Directory of coal production ownership, 1979  

SciTech Connect (OSTI)

Ownership patterns in the coal industry are highly complex. Many producers are diversified into other lines of activity. The pattern and extent of this diversification has varied through time. In the past, steel and nonferrous metals companies had major coal industry involvement. This is still true today. However, other types of enterprises have entered the industry de novo or through merger. Those of greatest significance in recent times have involved petroleum and particularly public utility companies. This report attempts to identify, as accurately as possible, production ownership patterns in the coal industry. The audience for this Directory is anyone who is interested in accurately tracing the ownership of coal companies to parent companies, or who is concerned about the structure of ownership in the US coal industry. This audience includes coal industry specialists, coal industry policy analysts, economists, financial analysts, and members of the investment community.

Clean coal technology. Coal utilisation by-products  

SciTech Connect (OSTI)

The need to remove the bulk of ash contained in flue gas from coal-fired power plants coupled with increasingly strict environmental regulations in the USA result in increased generation of solid materials referred to as coal utilisation by-products, or CUBs. More than 40% of CUBs were sold or reused in the USA in 2004 compared to less than 25% in 1996. A goal of 50% utilization has been established for 2010. The American Coal Ash Association (ACCA) together with the US Department of Energy's Power Plant Improvement Initiative (PPPI) and Clean Coal Power Initiative (CCPI) sponsor a number of projects that promote CUB utilization. Several are mentioned in this report. Report sections are: Executive summary; Introduction; Where do CUBs come from?; Market analysis; DOE-sponsored CUB demonstrations; Examples of best-practice utilization of CUB materials; Factors limiting the use of CUBs; and Conclusions. 14 refs., 1 fig., 5 tabs., 14 photos.

Coal Combustion Products Extension Program  

SciTech Connect (OSTI)

This final project report presents the activities and accomplishments of the ''Coal Combustion Products Extension Program'' conducted at The Ohio State University from August 1, 2000 to June 30, 2005 to advance the beneficial uses of coal combustion products (CCPs) in highway and construction, mine reclamation, agricultural, and manufacturing sectors. The objective of this technology transfer/research program at The Ohio State University was to promote the increased use of Ohio CCPs (fly ash, FGD material, bottom ash, and boiler slag) in applications that are technically sound, environmentally benign, and commercially competitive. The project objective was accomplished by housing the CCP Extension Program within The Ohio State University College of Engineering with support from the university Extension Service and The Ohio State University Research Foundation. Dr. Tarunjit S. Butalia, an internationally reputed CCP expert and registered professional engineer, was the program coordinator. The program coordinator acted as liaison among CCP stakeholders in the state, produced information sheets, provided expertise in the field to those who desired it, sponsored and co-sponsored seminars, meetings, and speaking at these events, and generally worked to promote knowledge about the productive and proper application of CCPs as useful raw materials. The major accomplishments of the program were: (1) Increase in FGD material utilization rate from 8% in 1997 to more than 20% in 2005, and an increase in overall CCP utilization rate of 21% in 1997 to just under 30% in 2005 for the State of Ohio. (2) Recognition as a ''voice of trust'' among Ohio and national CCP stakeholders (particularly regulatory agencies). (3) Establishment of a national and international reputation, especially for the use of FGD materials and fly ash in construction applications. It is recommended that to increase Ohio's CCP utilization rate from 30% in 2005 to 40% by 2010, the CCP Extension Program be expanded at OSU, with support from state and federal agencies, utilities, trade groups, and the university, to focus on the following four specific areas of promise: (a) Expanding use in proven areas (such as use of fly ash in concrete); (b) Removing or reducing regulatory and perceptual barriers to use (by working in collaboration with regulatory agencies); (c) Developing new or under-used large-volume market applications (such as structural fills); and (d) Placing greater emphasis on FGD byproducts utilization.

Create a Consortium and Develop Premium Carbon Products from Coal  

SciTech Connect (OSTI)

The objective of these projects was to investigate alternative technologies for non-fuel uses of coal. Special emphasis was placed on developing premium carbon products from coal-derived feedstocks. A total of 14 projects, which are the 2003 Research Projects, are reported herein. These projects were categorized into three overall objectives. They are: (1) To explore new applications for the use of anthracite in order to improve its marketability; (2) To effectively minimize environmental damage caused by mercury emissions, CO{sub 2} emissions, and coal impounds; and (3) To continue to increase our understanding of coal properties and establish coal usage in non-fuel industries. Research was completed in laboratories throughout the United States. Most research was performed on a bench-scale level with the intent of scaling up if preliminary tests proved successful. These projects resulted in many potential applications for coal-derived feedstocks. These include: (1) Use of anthracite as a sorbent to capture CO{sub 2} emissions; (2) Use of anthracite-based carbon as a catalyst; (3) Use of processed anthracite in carbon electrodes and carbon black; (4) Use of raw coal refuse for producing activated carbon; (5) Reusable PACs to recycle captured mercury; (6) Use of combustion and gasification chars to capture mercury from coal-fired power plants; (7) Development of a synthetic coal tar enamel; (8) Use of alternative binder pitches in aluminum anodes; (9) Use of Solvent Extracted Carbon Ore (SECO) to fuel a carbon fuel cell; (10) Production of a low cost coal-derived turbostratic carbon powder for structural applications; (11) Production of high-value carbon fibers and foams via the co-processing of a low-cost coal extract pitch with well-dispersed carbon nanotubes; (12) Use of carbon from fly ash as metallurgical carbon; (13) Production of bulk carbon fiber for concrete reinforcement; and (14) Characterizing coal solvent extraction processes. Although some of the projects funded did not meet their original goals, the overall objectives of the CPCPC were completed as many new applications for coal-derived feedstocks have been researched. Future research in many of these areas is necessary before implementation into industry.

Central Appalachia: Production potential of low-sulfur coal  

SciTech Connect (OSTI)

The vast preponderance of eastern US low sulfur and 1.2-lbs SO{sub 2}/MMBtu compliance coal comes from a relatively small area composed of 14 counties located in eastern Kentucky, southern West Virginia and western Virginia. These 14 counties accounted for 68% of all Central Appalachian coal production in 1989 as well as 85% of all compliance coal shipped to electric utilities from this region. A property-by-property analysis of total production potential in 10 of the 14 counties (Floyd, Knott, Letcher, Harlan, Martin and Pike in Kentucky and Boone, Kanawha, Logan and Mingo in West Virginia) resulted in the following estimates of active and yet to be developed properties: (1) total salable reserves for all sulfur levels were 5.9 billion tons and (2) 1.2-lbs. SO{sub 2}/MMBtu compliance'' reserves totaled 2.38 billion tons. This potential supply of compliance coal is adequate to meet the expanded utility demand expected under acid rain for the next 20 years. Beyond 2010, compliance supplies will begin to reach depletion levels in some areas of the study region. A review of the cost structure for all active mines was used to categorize the cost structure for developing potential supplies. FOB cash costs for all active mines in the ten counties ranged from $15 per ton to $35 per ton and the median mine cost was about $22 per ton. A total of 47 companies with the ability to produce and ship coal from owned or leased reserves are active in the ten-county region. Identified development and expansion projects controlled by active companies are capable of expanding the region's current production level by over 30 million tons per year over the next twenty years. Beyond this period the issue of reserve depletion for coal of all sulfur levels in the ten county region will become a pressing issue. 11 figs., 12 tabs.

PRODUCTION OF CARBON PRODUCTS USING A COAL EXTRACTION PROCESS  

SciTech Connect (OSTI)

This Department of Energy National Energy Technology Laboratory sponsored project developed carbon products, using mildly hydrogenated solvents to extract the organic portion of coal to create synthetic pitches, cokes, carbon foam and carbon fibers. The focus of this effort was on development of lower cost solvents, milder hydrogenation conditions and improved yield in order to enable practical production of these products. This technology is needed because of the long-term decline in production of domestic feedstocks such as petroleum pitch and coal tar pitch. Currently, carbon products represents a market of roughly 5 million tons domestically, and 19 million tons worldwide. Carbon products are mainly derived from feedstocks such as petroleum pitch and coal tar pitch. The domestic supply of petroleum pitch is declining because of the rising price of liquid fuels, which has caused US refineries to maximize liquid fuel production. As a consequence, the long term trend has a decline in production of petroleum pitch over the past 20 years. The production of coal tar pitch, as in the case of petroleum pitch, has likewise declined significantly over the past two decades. Coal tar pitch is a byproduct of metallurgical grade coke (metcoke) production. In this industry, modern metcoke facilities are recycling coal tar as fuel in order to enhance energy efficiency and minimize environmental emissions. Metcoke production itself is dependent upon the production requirements for domestic steel. Hence, several metcoke ovens have been decommissioned over the past two decades and have not been replaced. As a consequence sources of coal tar are being taken off line and are not being replaced. The long-term trend is a reduction in coal tar pitch production. Thus import of feedstocks, mainly from Eastern Europe and China, is on the rise despite the relatively large transportation cost. To reverse this trend, a new process for producing carbon products is needed. The process must be economically competitive with current processes, and yet be environmentally friendly as well. The solvent extraction process developed uses mild hydrogenation of low cost oils to create powerful solvents that can dissolve the organic portion of coal. The insoluble portion, consisting mainly of mineral matter and fixed carbon, is removed via centrifugation or filtration, leaving a liquid solution of coal chemicals and solvent. This solution can be further refined via distillation to meet specifications for products such as synthetic pitches, cokes, carbon foam and fibers. The most economical process recycles 85% of the solvent, which itself is obtained as a low-cost byproduct from industrial processes such as coal tar or petroleum refining. Alternatively, processes have been developed that can recycle 100% of the solvent, avoiding any need for products derived from petroleum or coal tar.

Estimating coal production peak and trends of coal imports in China  

SciTech Connect (OSTI)

More than 20 countries in the world have already reached a maximum capacity in their coal production (peak coal production) such as Japan, the United Kingdom and Germany. China, home to the third largest coal reserves in the world, is the world's largest coal producer and consumer, making it part of the Big Six. At present, however, China's coal production has not yet reached its peak. In this article, logistic curves and Gaussian curves are used to predict China's coal peak and the results show that it will be between the late 2020s and the early 2030s. Based on the predictions of coal production and consumption, China's net coal import could be estimated for coming years. This article also analyzes the impact of China's net coal import on the international coal market, especially the Asian market, and on China's economic development and energy security. 16 refs., 5 figs., 6 tabs.

SciTech Connect (OSTI)

The net liquid products from modern coal liquefaction processes are lower boiling and have much lower end points (mostly under 400{degree}C) than crude petroleum. Coal liquids have very low concentrations of heteroatoms, particularly S, and metals, and are free of resids and asphaltenes. High yields of low-S (0.01--0.03 wt %) naphtha, kerosene, and diesel fuel fractions can be obtained simply by atmospheric distillation, with a total yield of light fuel fractions ranging from 68 to 82 LV% (W260D exclusive). The coal naphtha has a low aromatics content (5--13 LV%), readily meeting projected year-2000 requirements. Its low Reid vapor pressure allows light components from other sources to be blended. The coal light distillate of in appropriate boiling range will be a good low-S blending stock for the light diesel fuel pool. The heavy distillate can be refined into a low-S No. 4 diesel fuel/fuel oil. This fraction, along with the >343{degree}C atmospheric bottoms, can be catalytically cracked or hydrocracked to make light liquid fuels. Thus, modern coal liquids should no longer be envisioned as thick liquids (or even solids) with high concentrations of aromatics and asphaltenes. Products obtained from advanced coal liquefaction technologies are more like light naphthene-base petroleum, but with lower heteroatoms and metals contents, and they are free of resids. Coal liquids are likely to be co-refined in existing petroleum refineries; and hydroprocessing of various severities would be needed for different fractions to produce quality blending stocks for refinery fuel pools.

The methods of steam coals usage for coke production  

SciTech Connect (OSTI)

Nowadays, high volatile bituminous coals are broadly used for metallurgical coke production in Russia. The share of such coals in the coking blend is variable from 20 to 40% by weight. There are some large coal deposits in Kuznetskii basin which have coals with low caking tendency. The low caking properties of such coals limit of its application in the coking process. At the same time the usage of low caking coals for coke production would allow flexibility of the feedstock for coke production. Preliminary tests, carried out in COAL-C's lab has shown some differences in coal properties with dependence on the size distribution. That is why the separation of the well-caking fraction from petrographically heterogeneous coals and its further usage in coking process may be promising. Another way for low caking coals application in the coke industry is briquettes production from such coals. This method has been known for a very long time. It may be divided into two possible directions. First is a direct coking of briquettes from the low caking coals. Another way is by adding briquettes to coal blends in defined proportion and combined coking. The possibility of application of coal beneficiation methods mentioned above was investigated in present work.

Land reclamation and strip-mined coal production in appalachia  

Science Journals Connector (OSTI)

This study quantifies the short-run impacts of reclamation on strip mining costs, coal prices, production, and employment in Appalachia. A process analysis model is developed and used to estimate short-run strip-mined coal supply functions under conditions of alternative reclamation requirements. Then, an econometric model is developed and used to estimate coal demand relations. Our results show that full reclamation has rather minor impacts. In 1972, full reclamation would have increased strip-mined coal production costs an average of $0.35 per ton, reduced strip-mined coal production by 10 million tons, and cost approximately 1600 jobs in Appalachia.

Hydrogen production with coal using a pulverization device  

DOE Patents [OSTI]

A method for producing hydrogen from coal is described wherein high temperature steam is brought into contact with coal in a pulverizer or fluid energy mill for effecting a steam-carbon reaction to provide for the generation of gaseous hydrogen. The high temperature steam is utilized to drive the coal particles into violent particle-to-particle contact for comminuting the particulates and thereby increasing the surface area of the coal particles for enhancing the productivity of the hydrogen.

Production of coal-based fuels and value-added products: coal to liquids using petroleum refinery streams  

SciTech Connect (OSTI)

We are studying several processes that utilize coal, coal-derived materials, or biomass in existing refining facilities. A major emphasis is the production of a coal-based replacement for JP-8 jet fuel. This fuel is very similar to Jet A and jet A-1 in commercial variation, so this work has significant carry-over into the private sector. We have been focusing on three processes that would be retrofitted into a refinery: (1) coal tar/refinery stream blending and hydro-treatment; (2) coal extraction using refinery streams followed by hydro-treatment; and (3) co-coking of coal blended with refinery streams. 4 figs., 5 tabs.

Electricity from coal and utilization of coal combustion by-products  

SciTech Connect (OSTI)

Most electricity in the world is conventionally generated using coal, oil, natural gas, nuclear energy, or hydropower. Due to environmental concerns, there is a growing interest in alternative energy sources for heat and electricity production. The major by-products obtained from coal combustion are fly ash, bottom ash, boiler slag, and flue gas desulfurization (FGD) materials. The solid wastes produced in coal-fired power plants create problems for both power-generating industries and environmentalists. The coal fly ash and bottom ash samples may be used as cementitious materials.

Coal combustion by-products: State regulatory overview  

SciTech Connect (OSTI)

Coal combustion by-products (CCBs) are generated from the combustion of coal for energy production. Approximately 82 million tons of CCBs are produced each year by electric utilities. (1991 Coal Combustion By-Product Production and Use, American Coal Ash Association, 1992.) There are several common types of CCBs produced by coal combustion--fly ash, bottom ash, boiler slag, flue gas desulfurization material (FGD) and fluidized bed combustion byproducts (FBC). Some CCBs, such as fly ash, have pozzolanic properties and may have cementitious properties, both of which are advantageous for engineering, construction and waste remediation applications. The American Society for Testing Materials (ASTM) in ASTM C-618 has created two classifications of useful and quality coal ash, Class F ash and Class C ash. Each class of coal ash has different pozzolanic and cementitious characteristics. Coal ash can be utilized in many manufacturing, mining, agricultural, engineering, construction and waste remediation applications. This is a review by state of regulations concerning coal combustion by-products.

Coal gasification power generation, and product market study. Topical report, March 1, 1995--March 31, 1996  

SciTech Connect (OSTI)

This Western Research Institute (WRI) project was part of a WRI Energy Resource Utilization Program to stimulate pilot-scale improved technologies projects to add value to coal resources in the Rocky Mountain region. The intent of this program is to assess the application potential of emerging technologies to western resources. The focus of this project is on a coal resource near the Wyoming/Colorado border, in Colorado. Energy Fuels Corporation/Kerr Coal Company operates a coal mine in Jackson County, Colorado. The coal produces 10,500 Btu/lb and has very low sulfur and ash contents. Kerr Coal Company is seeking advanced technology for alternate uses for this coal. This project was to have included a significant cost-share from the Kerr Coal Company ownership for a market survey of potential products and technical alternatives to be studied in the Rocky Mountain Region. The Energy Fuels Corporation/Kerr Coal Company and WRI originally proposed this work on a cost reimbursable basis. The total cost of the project was priced at $117,035. The Kerr Coal Company had scheduled at least $60,000.00 to be spent on market research for the project that never developed because of product market changes for the company. WRI and Kerr explored potential markets and new technologies for this resource. The first phase of this project as a preliminary study had studied fuel and nonfuel technical alternatives. Through related projects conducted at WRI, resource utilization was studied to find high-value materials that can be targeted for fuel and nonfuel use and eventually include other low-sulfur coals in the Rocky Mountain region. The six-month project work was spread over about a three-year period to observe, measure, and confirm over time-any trends in technology development that would lead to economic benefits in northern Colorado and southern Wyoming from coal gasification and power generation.

Coalbed methane production enhancement by underground coal gasification  

SciTech Connect (OSTI)

The sub-surface of the Netherlands is generally underlain by coal-bearing Carboniferous strata at greater depths (at many places over 1,500 m). These coal seams are generally thinner than 3 meter, occur in groups (5--15) within several hundred meters and are often fairly continuous over many square kilometers. In many cases they have endured complex burial history, influencing their methane saturation. In certain particular geological settings, a high, maximum coalbed methane saturation, may be expected. Carboniferous/Permian coals in the Tianjin-region (China) show many similarities concerning geological settings, rank and composition. Economical coalbed methane production at greater depths is often obstructed by the (very) low permeabilities of the coal seams as with increasing depth the deformation of the coal reduces both its macro-porosity (the cleat system) and microporosity. Experiments in abandoned underground mines, as well as after underground coal gasification tests indicate ways to improve the prospects for coalbed methane production in originally tight coal reservoirs. High permeability areas can be created by the application of underground coal gasification of one of the coal seams of a multi-seam cycle with some 200 meter of coal bearing strata. The gasification of one of the coal seams transforms that seam over a certain area into a highly permeable bed, consisting of coal residues, ash and (thermally altered) roof rubble. Additionally, roof collapse and subsidence will destabilize the overburden. In conjunction this will permit a better coalbed methane production from the remaining surrounding parts of the coal seams. Moreover, the effects of subsidence will influence the stress patterns around the gasified seam and this improves the permeability over certain distances in the coal seams above and below. In this paper the effects of the combined underground coal gasification and coalbed methane production technique are regarded for a single injection well. Known geotechnical aspects are combined with results from laboratory experiments on compaction of thermally treated rubble. An axi-symmetric numerical model is used to determine the effects induced by the gasified coal seam. The calculation includes the rubble formation, rubble compaction and induced stress effects in the overlying strata. Subsequently the stress effects are related to changes in coal permeability, based on experimental results of McKee et al.

However, conventional FTS catalysts produce undesirable waxes (C21+) that need to be upgraded to liquids (C5-C20) by hydrotreating. This adds significantly to the cost of FTS. The objectives of this project are (i) to demonstrate potential for CBTL cost reduction by maximizing the production of C5-C20 hydrocarbon liquids using a selective FTS catalyst and (ii) to evaluate the impacts of the addition of biomass to coal on product characteristics, carbon foot print, and economics.

Coal production forecast and low carbon policies in China  

Science Journals Connector (OSTI)

With rapid economic growth and industrial expansion, China consumes more coal than any other nation. Therefore, it is particularly crucial to forecast China's coal production to help managers make strategic decisions concerning China's policies intended to reduce carbon emissions and concerning the country's future needs for domestic and imported coal. Such decisions, which must consider results from forecasts, will have important national and international effects. This article proposes three improved forecasting models based on grey systems theory: the Discrete Grey Model (DGM), the Rolling DGM (RDGM), and the p value RDGM. We use the statistical data of coal production in China from 1949 to 2005 to validate the effectiveness of these improved models to forecast the data from 2006 to 2010. The performance of the models demonstrates that the p value RDGM has the best forecasting behaviour over this historical time period. Furthermore, this paper forecasts coal production from 2011 to 2015 and suggests some policies for reducing carbon and other emissions that accompany the rise in forecasted coal production.

Modeling of coal bed methane (CBM) production and CO2 sequestration in coal seams  

Science Journals Connector (OSTI)

A mathematical model was developed to predict the coal bed methane (CBM) production and carbon dioxide (CO2) sequestration in a coal seam accounting for the coal seam properties. The model predictions showed that, for a CBM production and dewatering process, the pressure could be reduced from 15.17 MPa to 1.56 MPa and the gas saturation increased up to 50% in 30 years for a 5.4 × 105 m2 of coal formation. For the CO2 sequestration process, the model prediction showed that the CO2 injection rate was first reduced and then slightly recovered over 3 to 13 years of injection, which was also evidenced by the actual in seam data. The model predictions indicated that the sweeping of the water in front of the CO2 flood in the cleat porosity could be important on the loss of injectivity. Further model predictions suggested that the injection rate of CO2 could be about 11 × 103 m3 per day; the injected CO2 would reach the production well, which was separated from the injection well by 826 m, in about 30 years. During this period, about 160 × 106 m3 of CO2 could be stored within a 21.4 × 105 m2 of coal seam with a thickness of 3 m.

Caustic washing for refining of direct coal liquefaction products  

SciTech Connect (OSTI)

Extensive research and development sponsored by the U.S. DOE/PETC over the past two decades has resulted in dramatic improvements in the quality of direct coal liquefaction products. High-quality coal-derived distillates are obtainable from catalytic two-stage liquefaction (TSL) processes, such as those developed at the Wilsonville, AL pilot plant and the Hydrocarbon Technologies Inc. (HTI) pilot plant and bench units. The products of the Wilsonville and HTI TSL operations are suitable as high quality feedstocks for producing transportation fuels in a refinery. These products have important quality advantages over crude petroleum: they are distillates boiling below about 700{degrees}F and are thus virtually free of resid and metals, and they have very low sulfur contents and low nitrogen contents. The coal liquids have carbon and hydrogen contents and Watson characterization factors within the range of crude petroleums. However, relative to crude petroleum, the crude coal products have elevated oxygen contents. This report describes the removal of phenols from coal liquids by caustic washing, and the the recovery of the cresylic acid by-product.

SNG Production from Coal: A Possible Solution to Energy Demand  

Science Journals Connector (OSTI)

Abstract In some areas of the world, natural gas demand cannot be fully satisfied either by domestic sources or foreign imports, while abundant coal resources are available. The conversion of coal to Substitute Natural Gas, SNG, by coal gasification and subsequent syngas methanation is one of the possible solutions to solve the problem. Foster Wheeler has developed a simple process for SNG production, named VESTA, utilizing catalysts from Clariant. The process concept has been proven by laboratory tests, and a demonstration unit will soon be completed. The VESTA process is very flexible and can handle syngas coming from several sources such as coal, biomass, petroleum coke and solid waste. In this paper our overview of the technology and its development status will be outlined.

SYSTEM ANALYSIS OF NUCLEAR-ASSISTED SYNGAS PRODUCTION FROM COAL  

SciTech Connect (OSTI)

A system analysis has been performed to assess the efficiency and carbon utilization of a nuclear-assisted coal gasification process. The nuclear reactor is a high-temperature helium-cooled reactor that is used primarily to provide power for hydrogen production via high-temperature electrolysis. The supplemental hydrogen is mixed with the outlet stream from an oxygen-blown coal gasifier to produce a hydrogen-rich gas mixture, allowing most of the carbon dioxide to be converted into carbon monoxide, with enough excess hydrogen to produce a syngas product stream with a hydrogen/carbon monoxide molar ratio of about 2:1. Oxygen for the gasifier is also provided by the high-temperature electrolysis process. Results of the analysis predict 90.5% carbon utilization with a syngas production efficiency (defined as the ratio of the heating value of the produced syngas to the sum of the heating value of the coal plus the high-temperature reactor heat input) of 66.1% at a gasifier temperature of 1866 K for the high-moisture-content lignite coal considered. Usage of lower moisture coals such as bituminous can yield carbon utilization approaching 100% and 70% syngas production efficiency.

Volcanic ash in feed coal and its influence on coal combustion products  

SciTech Connect (OSTI)

The US Geological Survey and the University of Kentucky Center for Applied Energy Research are collaborating with an Indiana Utility to determine the physical and chemical properties of feed coal and coal combustion products (CCPs) from a coal-fired power plant. The plant utilizes a low-sulfur (.23--.47 weight percent S) coal from the Powder River Basin, Wyoming. Scanning Electron Microscope (SEM) and X-ray diffraction (XRD) analysis of feed coal samples identified two mineral suites. A primary suite (not authigenic) consisting of quartz (detrital and volcanic beta-form grains), biotite, and minor zircon and a secondary authigenic mineral suite containing calcite, alumino-phosphates (crandallite and gorceixite), kaolinite, quartz, anatase, barite, and pyrite. The authigenic minerals are attributed to air-fall and reworked volcanic ash that was deposited in peat-forming mires. The Powder River Basin feed coals contain higher amounts of Ba, Ca, Mg, Na, Sr, and P compared to other analyzed eastern coals. These elements are associated with alumino-phosphate, biotite, calcite, and clay minerals. The element associations are indicative of coal that incorporated volcanic ash during deposition. XRD analysis of CCPs revealed a predominance of glass, perovskite, lime, gehlenite, quartz, and phosphates with minor amounts of periclase, anhydrite, hematite, and spinel group minerals in the fly ash; and quartz, plagioclase (albite and anorthite), pyroxene (augite and fassaite), rhodonite, and akermanite in the bottom ash. Microprobe and SEM analysis of fly ash samples revealed quartz, zircon, monazite, euhedral laths of corundum with merrillite, hematite, dendritic spinels/ferrites, and rounded grains of wollastonite with periclase. The abundant Ca and Mg mineral phases in the fly ashes are related to the presence of carbonate, clay, and phosphate minerals in the feed coal. The Ca- and Mg-rich mineral phases in the CCPs can be attributed to volcanic minerals deposited in the peat-forming mire. Dissolution and alteration of these minerals occurred either in the peat-forming sate or during coalification/diagenesis contributing to the authigenic mineral suite. Additionally, detrital mineral input and epigenetic ground-water flow may have affected the geochemistry of the feed coal.

Integrated production/use of ultra low-ash coal, premium liquids and clean char  

SciTech Connect (OSTI)

This integrated, multi-product approach for utilizing Illinois coal starts with the production of ultra low-ash coal and then converts it to high-vale, coal-derived, products. The ultra low-ash coal is produced by solubilizing coal in a phenolic solvent under ChemCoal{trademark} process conditions, separating the coal solution from insoluble ash, and then precipitating the clean coal by dilution of the solvent with methanol. Two major products, liquids and low-ash char, are then produced by mild gasification of the low-ash coal. The low ash-char is further upgraded to activated char, and/or an oxidized activated char which has catalytic properties. Characterization of products at each stage is part of this project.

Petrochemicals from oil, natural gas, coal and biomass: Production costs in 2030–2050  

Science Journals Connector (OSTI)

Methane, coal and biomass are being considered as alternatives to crude oil for the production of basic petrochemicals, such as light olefins. This paper is a study on the production costs of 24 process routes utilizing these primary energy sources. A wide range of projected energy prices in 2030–2050 found in the open literature is used. The basis for comparison is the production cost per t of high value chemicals (HVCs or light olefin-value equivalent). A Monte Carlo method was used to estimate the ranking of production costs of all 24 routes with 10,000 trials of varying energy prices and CO2 emissions costs (assumed to be within $0–100/t CO2; the total CO2 emissions, or cradle-to-grave CO2 emissions, were considered). High energy prices in the first three quarter of 2008 were tested separately. The main findings are:• Production costs: while the production costs of crude oil- and natural gas-based routes are within $500–900/t HVCs, those of coal- and biomass-based routes are mostly within $400–800/t HVCs. Production costs of coal- and biomass-based routes are in general quite similar while in some cases the difference is significant. Among the top seven most expensive routes, six are oil- and gas-based routes. Among the top seven least expensive routes, six are coal and biomass routes. • CO2 emissions costs: the effect of CO2 emissions costs was found to be strong on the coal-based routes and also quite significant on the biomass-based routes. However, the effect on oil- and gas-based routes is found to be small or relatively moderate. • Energy prices in 2008: most of the coal-based routes and biomass-based routes (particularly sugar cane) still have much lower production costs than the oil- and gas-based routes (even if international freight costs are included). To ensure the reduction of CO2 emissions in the long-term, we suggest that policies for the petrochemicals industry focus on stimulating the use of biomass as well as carbon capture and storage features for coal-based routes.

A compact XRF unit for determining total sulphur content in coals  

SciTech Connect (OSTI)

A microcomputer based x-ray fluorescence (XRF) unit was developed for off-line determination of total sulphur content in coal samples. The unit consisted of the x-ray exciting/measuring set and the microcomputer with a plug-in interface card, An Fe-55 radioisotope was used as the exciting source while a krypton-filled proportional counter was used to measure x-rays from the samples. The x-ray spectrum was simultaneously displayed on the microcomputer screen. For quantitative determination of sulphur, the intensities of sulphur K x-rays as well as calcium K x-rays and scattered x-rays were taken into account. The unit was tested with finely-ground, dried and compressed lignite, subbituminous and bituminous samples. It was found that for low-calcium coals the results were in good agreement with those obtained from the standard chemical analysis method within {+-}0.2 %S and within {+-}0.5 %S for high-calcium coals.

RESEARCH ON CARBON PRODUCTS FROM COAL USING AN EXTRACTIVE PROCESS  

SciTech Connect (OSTI)

This report presents the results of a one-year effort directed at the exploration of the use of coal as a feedstock for a variety of industrially-relevant carbon products. The work was basically divided into three focus areas. The first area dealt with the acquisition of laboratory equipment to aid in the analysis and characterization of both the raw coal and the coal-derived feedstocks. Improvements were also made on the coal-extraction pilot plant which will now allow larger quantities of feedstock to be produced. Mass and energy balances were also performed on the pilot plant in an attempt to evaluate the scale-up potential of the process. The second focus area dealt with exploring hydrogenation conditions specifically aimed at testing several less-expensive candidate hydrogen-donor solvents. Through a process of filtration and vacuum distillation, viable pitch products were produced and evaluated. Moreover, a recycle solvent was also isolated so that the overall solvent balance in the system could be maintained. The effect of variables such as gas pressure and gas atmosphere were evaluated. The pitch product was analyzed and showed low ash content, reasonable yield, good coking value and a coke with anisotropic optical texture. A unique plot of coke yield vs. pitch softening point was discovered to be independent of reaction conditions or hydrogen-donor solvent. The third area of research centered on the investigation of alternate extraction solvents and processing conditions for the solvent extraction step. A wide variety of solvents, co-solvents and enhancement additives were tested with varying degrees of success. For the extraction of raw coal, the efficacy of the alternate solvents when compared to the benchmark solvent, N-methyl pyrrolidone, was not good. However when the same coal was partially hydrogenated prior to solvent extraction, all solvents showed excellent results even for extractions performed at room temperature. Standard analyses of the extraction products indicated that they had the requisite properties of viable carbon-product precursors.

Low-rank coal oil agglomeration product and process  

DOE Patents [OSTI]

A selectively-sized, raw, low-rank coal is processed to produce a low ash and relative water-free agglomerate with an enhanced heating value and a hardness sufficient to produce a non-degradable, shippable fuel. The low-rank coal is treated, under high shear conditions, in the first stage to cause ash reduction and subsequent surface modification which is necessary to facilitate agglomerate formation. In the second stage the treated low-rank coal is contacted with bridging and binding oils under low shear conditions to produce agglomerates of selected size. The bridging and binding oils may be coal or petroleum derived. The process incorporates a thermal deoiling step whereby the bridging oil may be completely or partially recovered from the agglomerate; whereas, partial recovery of the bridging oil functions to leave as an agglomerate binder, the heavy constituents of the bridging oil. The recovered oil is suitable for recycling to the agglomeration step or can serve as a value-added product.

The process incorporates a thermal deoiling step whereby the bridging oil may be completely or partially recovered from the agglomerate; whereas, partial recovery of the bridging oil functions to leave as an agglomerate binder, the heavy constituents of the bridging oil. The recovered oil is suitable for recycling to the agglomeration step or can serve as a value-added product.

PRODUCTION OF CARBON PRODUCTS USING A COAL EXTRACTION PROCESS  

SciTech Connect (OSTI)

High melting temperature synthetic pitches (Synpitches) were created using coal derivatives produced from a solvent extraction technique. Solvent extraction is used to separate hydrocarbons from mineral matter as well as other insolubles. Mild hydrogenation can be used to chemically modify resultant material to produce a true pitch. There are three main techniques which can be used to tailor the softening point of the Synpitch. First, the softening point can be controlled by varying the conditions of hydrogenation, chiefly the temperature, pressure and residence time in a hydrogen overpressure. Second, by selectively distilling light hydrocarbons, the softening point of the remaining pitch can be raised. Third, the Synpitch can be blended with another mutually soluble pitch or hydrocarbon liquid. Through such techniques, spinnable isotropic Synpitches have been created from coal feedstocks. Characteristics of Synpitches include high cross-linking reactivity and high molecular weight, resulting in carbon fibers with excellent mechanical properties. To date, mechanical properties have been achieved which are comparable to the state of the art achievable with conventional coal tar pitch or petroleum pitch.

REFINERY INTEGRATION OF BY-PRODUCTS FROM COAL-DERIVED JET FUELS  

SciTech Connect (OSTI)

This report summarizes the accomplishments toward project goals during the first six months of the project to assess the properties and performance of coal based products. These products are in the gasoline, diesel and fuel oil range and result from coal based jet fuel production from an Air Force funded program. Specific areas of progress include generation of coal based material that has been fractionated into the desired refinery cuts, acquisition and installation of a research gasoline engine, and modification of diesel engines for use in evaluating diesel produced in the project. The desulfurization of sulfur containing components of coal and petroleum is being studied so that effective conversion of blended coal and petroleum streams can be efficiently converted to useful refinery products. Equipment is now in place to begin fuel oil evaluations to assess the quality of coal based fuel oil. Coal samples have procured and are being assessed for cleaning prior to use in coking studies.

A NOVEL MEMBRANE REACTOR FOR DIRECT HYDROGEN PRODUCTION FROM COAL  

SciTech Connect (OSTI)

Gas Technology Institute is developing a novel concept of membrane reactor coupled with a gasifier for high efficiency, clean and low cost production of hydrogen from coal. The concept incorporates a hydrogen-selective membrane within a gasification reactor for direct extraction of hydrogen from coal-derived synthesis gases. The objective of this project is to determine the technical and economic feasibility of this concept by screening, testing and identifying potential candidate membranes under high temperature, high pressure, and harsh environments of the coal gasification conditions. The best performing membranes will be selected for preliminary reactor design and cost estimates. Hydrogen permeation data for several perovskite membranes BCN (BaCe{sub 0.9}Nd{sub 0.1}O{sub 3-x}), SCE (SrCe{sub 0.9}Eu{sub 0.1}O{sub 3}) and SCTm (SrCe{sub 0.95}Tm{sub 0.05}O{sub 3}) have been successfully obtained for temperatures between 800 and 950 C and pressures from 1 to 12 bar in this project. However, it is known that the cerate-based perovskite materials can react with CO{sub 2}. Therefore, the stability issue of the proton conducting perovskite materials under CO{sub 2} or H{sub 2}S environments was examined. Tests were conducted in the Thermo Gravimetric Analyzer (TGA) unit for powder and disk forms of BCN and SCE. Perovskite materials doped with zirconium (Zr) are known to be resistant to CO{sub 2}. The results from the evaluation of the chemical stability for the Zr doped perovskite membranes are presented. During this reporting period, flowsheet simulation was also performed to calculate material and energy balance based on several hydrogen production processes from coal using high temperature membrane reactor (1000 C), low temperature membrane reactor (250 C), or conventional technologies. The results show that the coal to hydrogen process employing both the high temperature and the low temperature membrane reactors can increase the hydrogen production efficiency (cold gas efficiency) by more than 50% compared to the conventional process. Using either high temperature or low temperature membrane reactor process also results in an increase of the cold gas efficiencies as well as the thermal efficiencies of the overall process.

NETL: IEP - Coal Utilization By-Products : Regulatory Drivers  

Broader source: All U.S. Department of Energy (DOE) Office Webpages (Extended Search)

Regulatory Drivers Regulatory Drivers Since 1993, Federal Regulations have treated the four major large-volume CUB's -- fly ash, bottom ash, boiler slag, and flue gas desulfurization (FGD) byproducts -- as solid wastes that do not warrant regulation as hazardous wastes under Subtitle C of RCRA, as long as these CUBÂ’s were not co-managed with other waste materials. On May 22, 2000, EPA published a final Regulatory Determination [PDF-320KB] that retained the hazardous waste exemption for coal utilization by-products. EPA has concluded that fossil fuel combustion wastes do not warrant regulation as hazardous under Subtitle C of RCRA and is retaining the hazardous waste exemption for these wastes. However, the Agency has determined that national non-hazardous waste regulations under RCRA Subtitle D are needed for coal combustion wastes disposed in surface impoundments and landfills and used as minefilling. EPA also concluded beneficial uses of these wastes, other than for minefilling, pose no significant risk and no additional national regulations are needed. This determination affects more than 110 million tons of fossil fuel combustion wastes that are generated each year, virtually all from burning coal.

A Novel Membrane Reactor for Direct Hydrogen Production From Coal  

SciTech Connect (OSTI)

Gas Technology Institute has developed a novel concept of a membrane reactor closely coupled with a coal gasifier for direct extraction of hydrogen from coal-derived syngas. The objective of this project is to determine the technical and economic feasibility of this concept by screening, testing and identifying potential candidate membranes under the coal gasification conditions. The best performing membranes were selected for preliminary reactor design and cost estimate. The overall economics of hydrogen production from this new process was assessed and compared with conventional hydrogen production technologies from coal. Several proton-conducting perovskite membranes based on the formulations of BCN (BaCe{sub 0.8}Nd{sub 0.2}O{sub 3-x}), BCY (BaCe{sub 0.8}Y{sub 0.2}O{sub 3-x}), SCE (Eu-doped SrCeO{sub 3}) and SCTm (SrCe{sub 0.95}Tm{sub 0.05}O{sub 3}) were successfully tested in a new permeation unit at temperatures between 800 and 1040 C and pressures from 1 to 12 bars. The experimental data confirm that the hydrogen flux increases with increasing hydrogen partial pressure at the feed side. The highest hydrogen flux measured was 1.0 cc/min/cm{sup 2} (STP) for the SCTm membrane at 3 bars and 1040 C. The chemical stability of the perovskite membranes with respect to CO{sub 2} and H{sub 2}S can be improved by doping with Zr, as demonstrated from the TGA (Thermal Gravimetric Analysis) tests in this project. A conceptual design, using the measured hydrogen flux data and a modeling approach, for a 1000 tons-per-day (TPD) coal gasifier shows that a membrane module can be configured within a fluidized bed gasifier without a substantial increase of the gasifier dimensions. Flowsheet simulations show that the coal to hydrogen process employing the proposed membrane reactor concept can increase the hydrogen production efficiency by more than 50% compared to the conventional process. Preliminary economic analysis also shows a 30% cost reduction for the proposed membrane reactor process, assuming membrane materials meeting DOE's flux and cost target. Although this study shows that a membrane module can be configured within a fluidized bed gasifier, placing the membrane module outside the gasifier in a closely coupled way in terms of temperature and pressure can still offer the same performance advantage. This could also avoid the complicated fluid dynamics and heat transfer issues when the membrane module is installed inside the gasifier. Future work should be focused on improving the permeability and stability for the proton-conducting membranes, testing the membranes with real syngas from a gasifier and scaling up the membrane size.

DEVELOPMENT OF CONTINUOUS SOLVENT EXTRACTION PROCESSES FOR COAL DERIVED CARBON PRODUCTS  

SciTech Connect (OSTI)

The purpose of this DOE-funded effort is to develop continuous processes for solvent extraction of coal for the production of carbon products. These carbon products include materials used in metals smelting, especially in the aluminum and steel industries, as well as porous carbon structural material referred to as ''carbon foam'' and carbon fibers. The Hydrotreatment Facility is being prepared for trials with coal liquids. Raw coal tar distillate trials have been carried out by heating coal tar in the holding tank in the Hydrotreatment Facility. The liquids are centrifuged to warm the system up in preparation for the coal liquids. The coal tar distillate is then recycled to keep the centrifuge hot. In this way, the product has been distilled such that a softening point of approximately 110 C is reached. Then an ash test is conducted.

Coal precursors for production of carbon and graphite products. Final report  

SciTech Connect (OSTI)

The main goal of this program was to demonstrate the utility of coal extracts from the West Virginia University (WVU) extraction process as suitable base raw materials for the carbon products encompassed by the Carbon Products Consortium (CPC) team. These include binder and impregnation pitches, Coke for graphite electrodes, Cokes for anodes and specialty graphite, matrices for C/C composites and raw material for mesophase pitch fibers. Previous work in this program has shown that the WVU coal extraction process coupled with hydrotreatment, does have the potential for achieving this objective. The current effort involved screening and evaluation of extracts produced by the WVU Group and recommending appropriate materials for scaleup for subsequent evaluation by Consortium Team members. The program involved an initial characterization of small-scale extracts using standard analytical methods and mesophase formation studies. This was followed by feedback to the WVU Group and to the CPC partners with recommendation of material for scaleup. Similar analytical and mesophase studies on some of the scaled-up extracts was performed. The activation of the coal extraction residues for the purpose of producing a useful active carbon was investigated. A further task was to fabricate a small graphite artifact using Coke derived from coal extract as the filler and the coal extract itself as a binder. The results of the studies are summarized in this report.

Solvent extraction of bituminous coals using light cycle oil: characterization of diaromatic products in liquids  

SciTech Connect (OSTI)

Many studies of the pyrolytic degradation of coal-derived and petroleum-derived aviation fuels have demonstrated that the coal-derived fuels show better thermal stability, both with respect to deposition of carbonaceous solids and cracking to gases. Much previous work at our institute has focused on the use of refined chemical oil (RCO), a distillate from the refining of coal tar, blended with light cycle oil (LCO) from catalytic cracking of vacuum gas oil. Hydroprocessing of this blend forms high concentrations of tetralin and decalin derivatives that confer particularly good thermal stability on the fuel. However, possible supply constraints for RCO make it important to consider alternative ways to produce an 'RCO-like' product from coal in an inexpensive process. This study shows the results of coal extraction using LCO as a solvent. At 350{sup o}C at a solvent-to-coal ratio of 10:1, the conversions were 30-50 wt % and extract yields 28-40 wt % when testing five different coals. When using lower LCO/coal ratios, conversions and extract yields were much smaller; lower LCO/coal ratios also caused mechanical issues. LCO is thought to behave similarly to a nonpolar, non-hydrogen donor solvent, which would facilitate heat-induced structural relaxation of the coal followed by solubilization. The main components contributed from the coal to the extract when using Pittsburgh coal are di- and triaromatic compounds. 41 refs., 3 figs., 12 tabs.

Oxidation of Mercury in Products of Coal Combustion  

SciTech Connect (OSTI)

Laboratory measurements of mercury oxidation during selective catalytic reduction (SCR) of nitric oxide, simulation of pilot-scale measurements of mercury oxidation and adsorption by unburned carbon and fly ash, and synthesis of new materials for simultaneous oxidation and adsorption of mercury, were performed in support of the development of technology for control of mercury emissions from coal-fired boilers and furnaces. Conversion of gas-phase mercury from the elemental state to water-soluble oxidized form (HgCl{sub 2}) enables removal of mercury during wet flue gas desulfurization. The increase in mercury oxidation in a monolithic V{sub 2}O{sub 5}-WO{sub 3}/TiO{sub 2} SCR catalyst with increasing HCl at low levels of HCl (< 10 ppmv) and decrease in mercury oxidation with increasing NH{sub 3}/NO ratio during SCR were consistent with results of previous work by others. The most significant finding of the present work was the inhibition of mercury oxidation in the presence of CO during SCR of NO at low levels of HCl. In the presence of 2 ppmv HCl, expected in combustion products from some Powder River Basin coals, an increase in CO from 0 to 50 ppmv reduced the extent of mercury oxidation from 24 {+-} 3 to 1 {+-} 4%. Further increase in CO to 100 ppmv completely suppressed mercury oxidation. In the presence of 11-12 ppmv HCl, increasing CO from 0 to {approx}120 ppmv reduced mercury oxidation from {approx}70% to 50%. Conversion of SO{sub 2} to sulfate also decreased with increasing NH{sub 3}/NO ratio, but the effects of HCl and CO in flue gas on SO{sub 2} oxidation were unclear. Oxidation and adsorption of mercury by unburned carbon and fly ash enables mercury removal in a particulate control device. A chemical kinetic mechanism consisting of nine homogeneous and heterogeneous reactions for mercury oxidation and removal was developed to interpret pilot-scale measurements of mercury oxidation and adsorption by unburned carbon and fly ash in experiments at pilot scale, burning bituminous coals (Gale, 2006) and blends of bituminous coals with Powder River Basin coal (Gale, 2005). The removal of mercury by fly ash and unburned carbon in the flue gas from combustion of the bituminous coals and blends was reproduced with satisfactory accuracy by the model. The enhancement of mercury capture in the presence of calcium (Gale, 2005) explained a synergistic effect of blending on mercury removal across the baghouse. The extent of mercury oxidation, on the other hand, was not so well described by the simulation, because of oversensitivity of the oxidation process in the model to the concentration of unburned carbon. Combined catalysts and sorbents for oxidation and removal of mercury from flue gas at low temperature were based on surfactant-templated silicas containing a transition metal and an organic functional group. The presence of both metal ions and organic groups within the pore structure of the materials is expected to impart to them the ability to simultaneously oxidize elemental mercury and adsorb the resulting oxidized mercury. Twelve mesoporous organosilicate catalysts/sorbents were synthesized, with and without metals (manganese, titanium, vanadium) and organic functional groups (aminopropyl, chloropropyl, mercaptopropyl). Measurement of mercury oxidation and adsorption by the candidate materials remains for future work.

Process for the production of fuel gas from coal  

DOE Patents [OSTI]

An improved apparatus and process for the conversion of hydrocarbonaceous materials, such as coal, to more valuable gaseous products in a fluidized bed gasification reaction and efficient withdrawal of agglomerated ash from the fluidized bed is disclosed. The improvements are obtained by introducing an oxygen containing gas into the bottom of the fluidized bed through a separate conduit positioned within the center of a nozzle adapted to agglomerate and withdraw the ash from the bottom of the fluidized bed. The conduit extends above the constricted center portion of the nozzle and preferably terminates within and does not extend from the nozzle. In addition to improving ash agglomeration and withdrawal, the present invention prevents sintering and clinkering of the ash in the fluidized bed and permits the efficient recycle of fine material recovered from the product gases by contacting the fines in the fluidized bed with the oxygen as it emanates from the conduit positioned within the withdrawal nozzle. Finally, the present method of oxygen introduction permits the efficient recycle of a portion of the product gases to the reaction zone to increase the reducing properties of the hot product gas.

Washability of trace elements in product coals from Illinois mines. Technical report, September 1--November 30, 1993  

SciTech Connect (OSTI)

The existing trace element washability data on Illinois coals are based on float-sink methods, and these data are not applicable to modern froth flotation or column flotation processes. Particularly, there is a lack of washability data on samples from modern preparation plants, as well as other product (as-shipped) coals. The goal of this project is to provide the needed trace element washability data on as-shipped coals that were collected during 1992--1993 from Illinois mines. The results generated by this project will promote Illinois coals for such prospective new markets as feed materials for advanced gasification processes, for synthetic organic chemicals, and to meet new environmental requirements for their use in utility steam generation. During the first quarter, each of 34 project samples were ground to about {approximately}100 mesh size and cleaned by use of a special froth flotation technique (release analysis). The flotation products were analyzed for ash, moisture, and heating value (BTU). The data were then used to construct a series of different-washability curves. For example, these curves can show variation in BTU or combustible recovery as a function of the amount of ash or S rejected, or as a function of the weight of the flotation products. From the relationship between %cumulative BTU and %cumulative weight, nine composite samples each having 80% of the total BTU were prepared from the individual flotation products and submitted for trace element analysis.

PRODUCTION OF FOAMS, FIBERS AND PITCHES USING A COAL EXTRACTION PROCESS  

SciTech Connect (OSTI)

This Department of Energy National Energy Technology Laboratory sponsored project developed processes for converting coal feedstocks to carbon products, including coal-derived pitch, coke foams and fibers based on solvent extraction processes. A key technology is the use of hydrogenation accomplished at elevated temperatures and pressures to obtain a synthetic coal pitch. Hydrogenation, or partial direct liquefaction of coal, is used to modify the properties of raw coal such that a molten synthetic pitch can be obtained. The amount of hydrogen required to produce a synthetic pitch is about an order of magnitude less than the amount required to produce synthetic crude oil. Hence the conditions for synthetic pitch production consume very little hydrogen and can be accomplished at substantially lower pressure. In the molten state, hot filtration or centrifugation can be used to separate dissolved coal chemicals from mineral matter and insolubles (inertinite), resulting in the production of a purified hydrocarbon pitch. Alternatively, if hydrogenation is not used, aromatic hydrocarbon liquids appropriate for use as precursors to carbon products can obtained by dissolving coal in a solvent. As in the case for partial direct liquefaction pitches, undissolved coal is removed via hot filtration or centrifugation. Excess solvent is boiled off and recovered. The resultant solid material, referred to as Solvent Extracted Carbon Ore or SECO, has been used successfully to produce artificial graphite and carbon foam.

Advanced Multi-Product Coal Utilization By-Product Processing Plant  

SciTech Connect (OSTI)

The overall objective of this project is to design, construct, and operate an ash beneficiation facility that will generate several products from coal combustion ash stored in a utility ash pond. The site selected is LG&E's Ghent Station located in Carroll County, Kentucky. The specific site under consideration is the lower ash pond at Ghent, a closed landfill encompassing over 100 acres. Coring activities revealed that the pond contains over 7 million tons of ash, including over 1.5 million tons of coarse carbon and 1.8 million tons of fine (<10 {micro}m) glassy pozzolanic material. These potential products are primarily concentrated in the lower end of the pond adjacent to the outlet. A representative bulk sample was excavated for conducting laboratory-scale process testing while a composite 150 ton sample was also excavated for demonstration-scale testing at the Ghent site. A mobile demonstration plant with a design feed rate of 2.5 tph was constructed and hauled to the Ghent site to evaluate unit processes (i.e. primary classification, froth flotation, spiral concentration, secondary classification, etc.) on a continuous basis to determine appropriate scale-up data. Unit processes were configured into four different flowsheets and operated at a feed rate of 2.5 tph to verify continuous operating performance and generate bulk (1 to 2 tons) products for product testing. Cementitious products were evaluated for performance in mortar and concrete as well as cement manufacture process addition. All relevant data from the four flowsheets was compiled to compare product yields and quality while preliminary flowsheet designs were generated to determine throughputs, equipment size specifications and capital cost summaries. A detailed market study was completed to evaluate the potential markets for cementitious products. Results of the study revealed that the Ghent local fly ash market is currently oversupplied by more than 500,000 tpy and distant markets (i.e. Florida) are oversupplied as well. While the total US demand for ultrafine pozzolan is currently equal to demand, there is no reason to expect a significant increase in demand. Despite the technical merits identified in the pilot plant work with regard to beneficiating the entire pond ash stream, market developments in the Ohio River Valley area during 2006-2007 were not conducive to demonstrating the project at the scale proposed in the Cooperative Agreement. As a result, Cemex withdrew from the project in 2006 citing unfavorable local market conditions in the foreseeable future at the demonstration site. During the Budget Period 1 extensions provided by the DOE, CAER has contacted several other companies, including cement producers and ash marketing concerns for private cost share. Based on the prevailing demand-supply situation, these companies had expressed interest only in limited product lines, rather than the entire ash beneficiation product stream. Although CAER had generated interest in the technology, a financial commitment to proceed to Budget Period 2 could not be obtained from private companies. Furthermore, the prospects of any decisions being reached within a reasonable time frame were dim. Thus, CAER concurred with the DOE to conclude the project at the end of Budget Period 1, March 31, 2007. The activities presented in this report were carried out during the Cooperative Agreement period 08 November 2004 through 31 March 2007.

The recycling of the coal fly ash in glass production  

SciTech Connect (OSTI)

The recycling of fly ash obtained from the combustion of coal in thermal power plant has been studied. Coal fly ash was vitrified by melting at 1773 K for 5 hours without any additives. The properties of glasses produced from coal fly ash were investigated by means of Differential Thermal Analysis (DTA), X-ray Diffraction (XRD) and Scanning Electron Microscopy (SEM) techniques. DTA study indicated that there was only one endothermic peak at 1003 K corresponding to the glass transition temperature. XRD analysis showed the amorphous state of the glass sample produced from coal fly ash. SEM investigations revealed that the coal fly ash based glass sample had smooth surface. The mechanical, physical and chemical properties of the glass sample were also determined. Recycling of coal fly ash by using vitrification technique resulted to a glass material that had good mechanical, physical and chemical properties. Toxicity characteristic leaching procedure (TCLP) results showed that the heavy metals of Pb, Cr, Zn and Mn were successfully immobilized into the glass. It can be said that glass sample obtained by the recycling of coal fly ash can be taken as a non-hazardous material. Overall, results indicated that the vitrification technique is an effective way for the stabilization and recycling of coal fly ash.

HTGR-INTEGRATED COAL TO LIQUIDS PRODUCTION ANALYSIS  

SciTech Connect (OSTI)

As part of the DOE’s Idaho National Laboratory (INL) nuclear energy development mission, the INL is leading a program to develop and design a high temperature gas-cooled reactor (HTGR), which has been selected as the base design for the Next Generation Nuclear Plant. Because an HTGR operates at a higher temperature, it can provide higher temperature process heat, more closely matched to chemical process temperatures, than a conventional light water reactor. Integrating HTGRs into conventional industrial processes would increase U.S. energy security and potentially reduce greenhouse gas emissions (GHG), particularly CO2. This paper focuses on the integration of HTGRs into a coal to liquids (CTL) process, for the production of synthetic diesel fuel, naphtha, and liquefied petroleum gas (LPG). The plant models for the CTL processes were developed using Aspen Plus. The models were constructed with plant production capacity set at 50,000 barrels per day of liquid products. Analysis of the conventional CTL case indicated a potential need for hydrogen supplementation from high temperature steam electrolysis (HTSE), with heat and power supplied by the HTGR. By supplementing the process with an external hydrogen source, the need to “shift” the syngas using conventional water-gas shift reactors was eliminated. HTGR electrical power generation efficiency was set at 40%, a reactor size of 600 MWth was specified, and it was assumed that heat in the form of hot helium could be delivered at a maximum temperature of 700°C to the processes. Results from the Aspen Plus model were used to perform a preliminary economic analysis and a life cycle emissions assessment. The following conclusions were drawn when evaluating the nuclear assisted CTL process against the conventional process: • 11 HTGRs (600 MWth each) are required to support production of a 50,000 barrel per day CTL facility. When compared to conventional CTL production, nuclear integration decreases coal consumption by 66% using electrolysis and nuclear power as the hydrogen source. In addition, nuclear integration decreases CO2 emissions by 84% if sequestration is assumed and 96% without sequestration, when compared to conventional CTL. • The preliminary economic assessment indicates that the incorporation of 11 HTGRs and the associated HTSEs impacts the expected return on investment, when compared to conventional CTL with or without sequestration. However, in a carbon constrained scenario, where CO2 emissions are taxed and sequestration is not an option, a reasonable CO2 tax would equate the economics of the nuclear assisted CTL case with the conventional CTL case. The economic results are preliminary, as they do not include economies of scale for multiple HTGRs and are based on an uncertain reactor cost estimate. Refinement of the HTGR cost estimate is currently underway. • To reduce well to wheel (WTW) GHG emissions below baseline (U.S. crude mix) or imported crude derived diesel, integration of an HTGR is necessary. WTW GHG emissions decrease 8% below baseline crude with nuclear assisted CTL. Even with CO2 sequestration, conventional CTL WTW GHG emissions are 24% higher than baseline crude emissions. • Current efforts are underway to investigate the incorporation of nuclear integrated steam methane reforming for the production of hydrogen, in place of HTSE. This will likely reduce the number of HTGRs required for the process.

A global coal production forecast with multi-Hubbert cycle analysis  

Science Journals Connector (OSTI)

Based on economic and policy considerations that appear to be unconstrained by geophysics, the Intergovernmental Panel on Climate Change (IPCC) generated forty carbon production and emissions scenarios. In this paper, we develop a base-case scenario for global coal production based on the physical multi-cycle Hubbert analysis of historical production data. Areas with large resources but little production history, such as Alaska and the Russian Far East, are treated as sensitivities on top of this base-case, producing an additional 125 Gt of coal. The value of this approach is that it provides a reality check on the magnitude of carbon emissions in a business-as-usual (BAU) scenario. The resulting base-case is significantly below 36 of the 40 carbon emission scenarios from the IPCC. The global peak of coal production from existing coalfields is predicted to occur close to the year 2011. The peak coal production rate is 160 EJ/y, and the peak carbon emissions from coal burning are 4.0 Gt C (15 Gt CO2) per year. After 2011, the production rates of coal and CO2 decline, reaching 1990 levels by the year 2037, and reaching 50% of the peak value in the year 2047. It is unlikely that future mines will reverse the trend predicted in this BAU scenario.

Coal-bed methane production in eastern Kansas: Its potential and restraints  

SciTech Connect (OSTI)

In 1921 and again in 1988, workers demonstrated that the high volatile A and B coals of the Pennsylvanian Cherokee Group can be produced economically from vertically drilled holes, and that some of these coals have a gas content as high as 200 ft{sup 3}/ton. Detailed subsurface mapping on a county-by-county basis using geophysical logs shows the Weir coal seam to be the thickest (up to 6 ft thick) and to exist in numerous amoeba-shaped pockets covering several thousand acres. Lateral pinch-out into deltaic sands offers a conventional gas source. New attention to geophysical logging shows most coals have a negative SP response, high resistivities, and densities of 1.6 g/cm{sup 3}. Highly permeable coals cause lost circulation during drilling and thief zones during cementing, and they are the source of abundant unwanted salt water. Low-permeability coals can be recognized by their high fracture gradients, which are difficult to explain but are documented to exceed 2.2. Current successful completions use both limited-entry, small-volume nitrogen stimulations or an open hole below production casing. Subsurface coals are at normal Mid-Continent pressures and may be free of water. Initially, some wells flow naturally without pumping. Saltwater disposal is often helped by the need for water in nearby waterflood projects and the easy availability of state-approved saltwater disposal wells in Mississippi and Arbuckle carbonates. Recent attempts to recomplete coal zones in slim-hole completions are having mixed results. The major restraints to coal-bed methane production are restricted to low permeability of the coals and engineering problems, not to the availability or gas content of the coals.

Controls of coal fabric on coalbed gas production and compositional shift in both field production and canister desorption tests  

SciTech Connect (OSTI)

The production rates of coalbed gas wells commonly vary significantly, even in the same field with similar reservoir permeability and gas content. The compositional variation in produced gas is also not everywhere predictable, although in most fields produced gas becomes progressively enriched in CO, through the production life of a reservoir, such as parts of the San Juan basin. In contrast, it is generally observed that the ratio of CO{sub 2}:CH{sub 4} declines with time during field and laboratory desorption testing of coal cores. In this study, we investigate numerically the importance of coal fabric, namely cleat spacing and aperture width, on the performance of coalbed gas wells and gas compositional shifts during production. Because of the cubic relationship between fracture permeability and fracture aperture width (and thus fracture porosity) for a given cleat permeability, the production profile of coal seams varies depending on whether the permeability is distributed among closely spaced fractures (cleat) with narrower apertures or more widely spaced fractures (cleat) with wider apertures. There is a lower fracture porosity for coal with widely spaced fractures than for coal with closely spaced fractures. Therefore, the relative permeability to gas increases more rapidly for coals with more widely spaced cleats as less dewatering from fractures is required, assuming that the fractures are initially water saturated. The enrichment of CO{sub 2} in the production gas with time occurs because of the stronger adsorption of coals for CO{sub 2} than CH{sub 4}. However, during desorption of coal cores, CO{sub 2} desorbs more rapidly than methane because desorption rate is governed more by diffusion than by sorption affinity, and CO{sub 2} has much higher effective diffusivity in microporous coals than CH{sub 4}.

Strontium Isotope Study of Coal Untilization By-products Interacting with Environmental Waters  

SciTech Connect (OSTI)

Sequential leaching experiments on coal utilization by-products (CUB) were coupled with chemical and strontium (Sr) isotopic analyses to better understand the influence of coal type and combustion processes on CUB properties and the release of elements during interaction with environmental waters during disposal. Class C fly ash tended to release the highest quantity of minor and trace elements—including alkaline earth elements, sodium, chromium, copper, manganese, lead, titanium, and zinc—during sequential extraction, with bottom ash yielding the lowest. Strontium isotope ratios ({sup 87}Sr/{sup 86}Sr) in bulk-CUB samples (total dissolution of CUB) are generally higher in class F ash than in class C ash. Bulk-CUB ratios appear to be controlled by the geologic source of the mineral matter in the feed coal, and by Sr added during desulfurization treatments. Leachates of the CUB generally have Sr isotope ratios that are different than the bulk value, demonstrating that Sr was not isotopically homogenized during combustion. Variations in the Sr isotopic composition of CUB leachates were correlated with mobility of several major and trace elements; the data suggest that arsenic and lead are held in phases that contain the more radiogenic (high-{sup 87}Sr/{sup 86}Sr) component. A changing Sr isotope ratio of CUB-interacting waters in a disposal environment could forecast the release of certain strongly bound elements of environmental concern. This study lays the groundwork for the application of Sr isotopes as an environmental tracer for CUB–water interaction.

Process for forming coal compacts and product thereof  

DOE Patents [OSTI]

A process for forming durable, mechanically strong compacts from coal particulates without use of a binder is disclosed. The process involves applying a compressive stress to a particulate feed comprising substantially water-saturated coal particles while the feed is heated to a final compaction temperature in excess of about 100.degree. C. The water present in the feed remains substantially in the liquid phase throughout the compact forming process. This is achieved by heating and compressing the particulate feed and cooling the formed compact at a pressure sufficient to prevent water present in the feed from boiling. The compacts produced by the process have a moisture content near their water saturation point. As a result, these compacts absorb little water and retain exceptional mechanical strength when immersed in high pressure water. The process can be used to form large, cylindrically-shaped compacts from coal particles (i.e., "coal logs") so that the coal can be transported in a hydraulic coal log pipeline.

The US coal industry 1996  

SciTech Connect (OSTI)

Several years ago a friend and former classmate, Dr. Doug Dahl, put the coal industry into perspective. At that time he worked for Consol, whose parent company was DuPont. I will use his story, but update it with today`s statistics. As can be seen in Figure 1, total US coal production continues to show healthy growth. In 1995 we produced 1,032,000,000 tons, and 1,046,000,000 tons are projected for 1996. Unfortunately as seen in Figure 2, the average price per ton of coal sold is still dropping. The coal industry is experiencing the unusual situation of falling coal prices with increasing coal demand! In 1994 (1995 data not available) the average price for a ton of coal was only $19.41. Multiplying the two numbers, yields the total sales value for our entire industry, $20.1 billion in 1994. That`s roughly half the approximately $40 billion per year sales value for a single chemical company, DuPont, Dr. Dahl`s parent company. As Dr. Dahl pointed out, the coal industry just isn`t that big. As we can see in Figure 3, the yearly trends show that the total value of the US coal production is shrinking. The total value has fallen through the 90`s and follows the average price per ton trend. Even increases in production have generally not been enough to offset the falling prices.

Estimates of central Appalachian coal reserves by cost of production and sulfur content  

SciTech Connect (OSTI)

This study provides information on the quantity, quality, and production costs for all minable coal reserves in the major coal-producing counties of central Appalachia, a region that contains the large majority of low-sulfur and compliance coal reserves in the eastern US. Presently, the best source of detailed reserve information in the Appalachian region is the estimates produced by the mining and land holding companies that control the reserves. The authors have been able to obtain overall reserve estimates based on the detailed geological and engineering studies conducted by these companies. In areas where this information does not exist, the authors have relied on published estimates of reserves and modified these estimates based on known conditions on surrounding properties. This reserve information has been combined with data on coal quality and mining costs to produce cost curves for all minable coal reserves by sulfur content. Results to date indicate that most of the major coal-producing counties in central Appalachia will be able to increase production levels significantly on a sustainable basis for at least the next 20 years, without major real increases in coal prices.

Thermal-destruction products of coal in the blast-furnace gas-purification system  

SciTech Connect (OSTI)

The lean, poorly clinkering coal and anthracite used to replace coke in blast furnaces has a considerable content of volatile components (low-molecular thermaldestruction products), which enter the water and sludge of the blast-furnace gas-purification system as petroleum products. Therefore, it is important to study the influence of coal on the petroleum-product content in the water and sludge within this system. The liberation of primary thermal-destruction products is investigated for anthracite with around 4 wt % volatiles, using a STA 449C Jupiter thermoanalyzer equipped with a QMC 230 mass spectrometer. The thermoanalyzer determines small changes in mass and thermal effects with high accuracy (weighing accuracy 10{sup -8} g; error in measuring thermal effects 1 mV). This permits experiments with single layers of coal particles, eliminating secondary reactions of its thermal-destruction products.

ENHANCED COAL BED METHANE PRODUCTION AND SEQUESTRATION OF CO2 IN UNMINEABLE COAL SEAMS  

SciTech Connect (OSTI)

The availability of clean, affordable energy is essential for the prosperity and security of the United States and the world in the 21st century. Emissions of carbon dioxide (CO{sub 2}) into the atmosphere are an inherent part of electricity generation, transportation, and industrial processes that rely on fossil fuels. These energy-related activities are responsible for more than 80 percent of the U.S. greenhouse gas emissions, and most of these emissions are CO{sub 2}. Over the last few decades, an increased concentration of CO{sub 2} in the earth's atmosphere has been observed. Carbon sequestration technology offers an approach to redirect CO{sub 2} emissions into sinks (e.g., geologic formations, oceans, soils and vegetation) and potentially stabilize future atmospheric CO{sub 2} levels. Coal seams are attractive CO{sub 2} sequestration sinks, due to their abundance and proximity to electricity-generation facilities. The recovery of marketable coalbed methane (CBM) provides a value-added stream, potentially reducing the cost to sequester CO{sub 2} gas. Much research is needed to evaluate this technology in terms of CO{sub 2} storage capacity, sequestration stability, commercial feasibility and overall economics. CONSOL Energy Inc., Research & Development (CONSOL), with support from the US DOE, has embarked on a seven-year program to construct and operate a coal bed sequestration site composed of a series of horizontally drilled wells that originate at the surface and extend through two overlying coal seams. Once completed, all of the wells will be used initially to drain CBM from both the upper (mineable) and lower (unmineable) coal seams. After sufficient depletion of the reservoir, centrally located wells in the lower coal seam will be converted from CBM drainage wells to CO{sub 2} injection ports. CO{sub 2} will be measured and injected into the lower unmineable coal seam while CBM continues to drain from both seams. In addition to metering all injected CO{sub 2} and recovered CBM, the program includes additional monitoring wells to further examine horizontal and vertical migration of CO{sub 2}. This is the fifth Technical Progress report for the project. Progress this period was focused on reclamation of the north access road and north well site, and development of revised drilling methods. This report provides a concise overview of project activities this period and plans for future work.

An Industrial-Based Consortium to Develop Premium Carbon Products from Coal Final Report - Part 1  

SciTech Connect (OSTI)

Since 1998, The Pennsylvania State University successfully managed the Consortium for Premium Carbon Products from Coal (CPCPC), which was a vehicle for industry-driven research on the promotion, development, and transfer of innovative technologies on premium carbon products from coal to the U.S. industry. The CPCPC was an initiative led by Penn State, its cocharter member West Virginia University (WVU), and the U.S. Department of Energy's (DOE) National Energy Technology Laboratory (NETL), who also provided the base funding for the program, with Penn State responsible for consortium management. CPCPC began in 1998 under DOE Cooperative Agreement No. DE-FC26-98FT40350. This agreement ended November 2004 but the CPCPC activity continued under cooperative agreement No. DE-FC26-03NT41874, which started October 1, 2003 and ended December 31, 2010. The objective of the second agreement was to continue the successful operation of the CPCPC. The CPCPC enjoyed tremendous success with its organizational structure, which included Penn State and WVU as charter members, numerous industrial affiliate members, and strategic university affiliate members together with NETL, forming a vibrant and creative team for innovative research in the area of transforming coal to carbon products. The key aspect of CPCPC was its industry-led council that selected proposals submitted by CPCPC members to ensure CPCPC target areas had strong industrial support. CPCPC had 58 member companies and universities engaged over the 7-year period of this contract. Members were from 17 states and five countries outside of the U.S. During this period, the CPCPC Executive Council selected 46 projects for funding. DOE/CPCPC provided $3.9 million in funding or an average of $564,000 per year. The total project costs were $5.45 million with $1.5 million, or ~28% of the total, provided by the members as cost share. Total average project size was $118,000 with $85,900 provided by DOE/CPCPC. In addition to the research, technology transfer/outreach was a large component of CPCPC's activities. Efficient technology transfer was critical for the deployment of new technologies into the field. CPCPC organized and hosted technology transfer meetings, tours, and tutorials, attended outreach conferences and workshops to represent CPCPC and attract new members, prepared and distributed reports and publications, and developed and maintained a Web site. The second contract ended December 31, 2010, and it is apparent that CPCPC positively impacted the carbon industry and coal research. Statistics and information were compiled to provide a comprehensive account of the impact the consortium had and the beneficial outcomes of many of the individual projects. Project fact sheet, success stories, and other project information were prepared. Two topical reports, a Synthesis report and a Web report, were prepared detailing this information.

Preparation and evaluation of coal extracts as precursors for carbon and graphite products  

SciTech Connect (OSTI)

A coal extraction process coupled with coal hydrotreatment has been shown capable of producing suitable precursors for a variety of commercially important carbon and graphite products. The N-methylpyrolidone (NMP) extracts of hydrotreated coals have been analytically and chemically characterized and shown to have properties acceptable for use as binder and impregnation pitch. Mesophase formation studies have demonstrated their capability for producing both needle and anode grade coke as well as precursors for mesophase pitch fibers. A graphite artifact has been produced using a coal extract as a binder and coke derived from the extract as a filler. Further evaluation of the extract materials is being carried out by industrial members of the Carbon Products Consortium.

ENHANCED COAL BED METHANE PRODUCTION AND SEQUESTRATION OF CO2 IN UNMINEABLE COAL SEAMS  

SciTech Connect (OSTI)

The availability of clean, affordable energy is essential for the prosperity and security of the United States and the world in the 21st century. Carbon dioxide (CO{sub 2}) emissions to the atmosphere are an inherent part of energy-related activities, such as electricity generation, transportation, and building systems. These energy-related activities are responsible for roughly 85% of the U.S. greenhouse gas emissions, and 95% of these emissions are dominated by CO{sub 2}. Over the last few decades, an increased concentration of CO{sub 2} in the earth's atmosphere has been observed. Many scientists believe greenhouse gases, particularly CO{sub 2}, trap heat in the earth's atmosphere. Carbon sequestration technology offers an approach to redirect CO{sub 2} emissions into sinks (e.g., geologic formations, oceans, soils, and vegetation) and potentially stabilize future atmospheric CO{sub 2} levels. Coal seams are attractive CO{sub 2} sequestration sinks, due to their abundance and proximity to electricity-generation facilities. The recovery of marketable coal bed methane (CBM) provides a value-added stream, reducing the cost to sequester CO{sub 2} gas. Much research is needed to evaluate this technology in terms of CO{sub 2} storage capacity, sequestration stability, commercial feasibility and overall economics. CONSOL Energy, with support from the U.S. DOE, is conducting a seven-year program to construct and operate a coal bed sequestration site composed of a series of horizontally drilled wells that originate at the surface and extend through overlying coal seams in the subsurface. Once completed, the wells will be used to initially drain CBM from both the upper (mineable) and lower (unmineable) coal seams. After sufficient depletion of the reservoir, centrally located wells in the lower coal seam will be converted from CBM drainage wells to CO{sub 2} injection ports. CO{sub 2} will be measured and injected into the lower unmineable coal seam while CBM continues to drain from both seams. In addition to metering all injected CO{sub 2} and CBM produced, the program includes a plan to monitor horizontal migration of CO{sub 2} within the lower seam. This is the second Technical Progress report for the project. Progress to date has been focused on pre-construction activities; in particular, attaining site approvals and securing property rights for the project. This report provides a concise overview of project activity this period and plans for future work. This is the second semi-annual Technical Progress report under the subject agreement. During this report period, progress was made in completing the environmental assessment report, securing land and coal rights, and evaluating drilling strategies. These aspects of the project are discussed in detail in this report.

Development of Continuous Solvent Extraction Processes for Coal Derived Carbon Products  

SciTech Connect (OSTI)

This DOE NETL-sponsored effort seeks to develop continuous processes for producing carbon products from solvent-extracted coal. A key process step is removal of solids from liquefied coal. Three different processes were compared: gravity separation, centrifugation using a decanter-type Sharples Pennwalt centrifuge, and a Spinner-II centrifuge. The data suggest that extracts can be cleaned to as low as 0.5% ash level and probably lower using a combination of these techniques.

Annual Energy Outlook 2006 with Projections to 2030 - Coal  

Gasoline and Diesel Fuel Update (EIA)

Coal Coal Annual Energy Outlook 2006 with Projections to 2030 Market Share of Western Coal Continues To Increase U.S. coal production has remained near 1,100 million tons annually since 1996. In the AEO2006 reference case, increasing coal use for electricity generation at existing plants and construction of a few new coal-fired plants lead to annual production increases that average 1.1 percent per year from 2004 to 2015, when total production is 1,272 million tons. The growth in coal production is even stronger thereafter, averaging 2.0 percent per year from 2015 to 2030, as substantial amounts of new coal-fired generating capacity are added, and several CTL plants are brought on line.

Co-pyrolysis of low rank coals and biomass: Product distributions  

SciTech Connect (OSTI)

Pyrolysis and gasification of combined low rank coal and biomass feeds are the subject of much study in an effort to mitigate the production of green house gases from integrated gasification combined cycle (IGCC) systems. While co-feeding has the potential to reduce the net carbon footprint of commercial gasification operations, the effects of co-feeding on kinetics and product distributions requires study to ensure the success of this strategy. Southern yellow pine was pyrolyzed in a semi-batch type drop tube reactor with either Powder River Basin sub-bituminous coal or Mississippi lignite at several temperatures and feed ratios. Product gas composition of expected primary constituents (CO, CO{sub 2}, CH{sub 4}, H{sub 2}, H{sub 2}O, and C{sub 2}H{sub 4}) was determined by in-situ mass spectrometry while minor gaseous constituents were determined using a GC-MS. Product distributions are fit to linear functions of temperature, and quadratic functions of biomass fraction, for use in computational co-pyrolysis simulations. The results are shown to yield significant nonlinearities, particularly at higher temperatures and for lower ranked coals. The co-pyrolysis product distributions evolve more tar, and less char, CH{sub 4}, and C{sub 2}H{sub 4}, than an additive pyrolysis process would suggest. For lignite co-pyrolysis, CO and H{sub 2} production are also reduced. The data suggests that evolution of hydrogen from rapid pyrolysis of biomass prevents the crosslinking of fragmented aromatic structures during coal pyrolysis to produce tar, rather than secondary char and light gases. Finally, it is shown that, for the two coal types tested, co-pyrolysis synergies are more significant as coal rank decreases, likely because the initial structure in these coals contains larger pores and smaller clusters of aromatic structures which are more readily retained as tar in rapid co-pyrolysis.

The purpose of this DOE-funded effort is to develop continuous processes for solvent extraction of coal for the production of carbon products. The largest applications are those which support metals smelting, such as anodes for aluminum smelting and electrodes for arc furnaces. Other carbon products include materials used in creating fuels for the Direct Carbon Fuel Cell, and porous carbon structural material referred to as ''carbon foam'' and carbon fibers. During this reporting period, hydrotreatment of solvent was completed in preparation for pitch fabrication for graphite electrodes. Coal digestion has lagged but is expected to be complete by next quarter. Studies are reported on coal dissolution, pitch production, foam synthesis using physical blowing agents, and alternate coking techniques.

EFFECTS OF COFIRING LIGNIN AND BIOSOLIDS WITH COAL ON FIRESIDE PERFORMANCE AND COMBUSTION PRODUCTS  

SciTech Connect (OSTI)

Lignin, derived from municipal solid waste and biosolid feedstocks using Masada Resource Group's patented CES OxyNol{trademark} process, and acidified biosolids were evaluated as supplemental fuels with coal for producing steam and electricity. Tests were conducted in a pilot-scale (550,000-Btu/hr [580-MJ/hr]) combustion system to evaluate the effects of coal characteristics, blend mixture (on a dry wt% basis) and furnace exit gas temperature (FEGT) on boiler heat-exchange surface slagging and fouling, NO{sub x} and SO{sub x} production, fly ash characteristics, and combustion efficiency. The effects of blending lignin and acidified biosolids with coal on fuel handling and pulverization characteristics were also addressed. An 80 wt% Colorado--20 wt% subbituminous Powder River Basin coal blend from the Tennessee Valley Authority Colbert Steam Plant, hereafter referred to as the Colbert coal, and a bituminous Pittsburgh No. 8 coal were tested. The lignin and acidified biosolids were characterized by possessing higher moisture content and lower carbon, hydrogen, and heating values relative to the coals. Ash contents of the fuels were similar. The lignin also possessed higher concentrations of TiO{sub 2}, CaO, and SO{sub 3} and lower concentrations of SiO{sub 2}, Al{sub 2}O{sub 3}, Fe{sub 2}O{sub 3}, K{sub 2}O, and N relative to the coals. The sulfur content of lignin could be reduced through a more thorough washing and drying of the lignin in an efficient commercial-scale dewatering device. Acidified biosolids were distinguished by higher concentrations of P{sub 2}O{sub 5} and MgO and lower SiO{sub 2} and Al{sub 2}O{sub 3} relative to the other fuels. Trace element concentrations, especially for Cr, Pb, Hg, and Ni, were generally greater in the lignin and acidified biosolid fuels relative to the Colbert coal. Maximum trace element emission factors were calculated for 95:5 Colbert coal--lignin and 90:5:5 Colbert coal--lignin--acidified biosolid blends and compared to U.S. Environmental Protection Agency emission factors for pulverized coal-fired units that are unequipped with pollution control devices. Calculated maximum trace element emission factors for the fuel blends were generally less than or within the range of those for the uncontrolled coal-fired units, except for Cr and Pb which were greater.

Utilization of coal mine methane for methanol and SCP production. Topical report, May 5, 1995--March 4, 1996  

SciTech Connect (OSTI)

The feasibility of utilizing a biological process to reduce methane emissions from coal mines and to produce valuable single cell protein (SCP) and/or methanol as a product has been demonstrated. The quantities of coal mine methane from vent gas, gob wells, premining wells and abandoned mines have been determined in order to define the potential for utilizing mine gases as a resource. It is estimated that 300 MMCFD of methane is produced in the United States at a typical concentration of 0.2-0.6 percent in ventilation air. Of this total, almost 20 percent is produced from the four Jim Walter Resources (JWR) mines, which are located in very gassy coal seams. Worldwide vent gas production is estimated at 1 BCFD. Gob gas methane production in the U.S. is estimated to be 38 MMCFD. Very little gob gas is produced outside the U.S. In addition, it is estimated that abandoned mines may generate as much as 90 MMCFD of methane. In order to make a significant impact on coal mine methane emissions, technology which is able to utilize dilute vent gases as a resource must be developed. Purification of the methane from the vent gases would be very expensive and impractical. Therefore, the process application must be able to use a dilute methane stream. Biological conversion of this dilute methane (as well as the more concentrated gob gases) to produce single cell protein (SCP) and/or methanol has been demonstrated in the Bioengineering Resources, Inc. (BRI) laboratories. SCP is used as an animal feed supplement, which commands a high price, about $0.11 per pound.

Reuse of coal combustion by-products: A new profit center  

SciTech Connect (OSTI)

Coal combustion by-products (CCBs) are generated from the combustion of coal for energy production. Approximately 82 million tons of CCBs are produced each year by electric utilities. There are several common types of CCBs produced by coal combustion--fly ash, bottom ash, boiler slag, flue gas desulfurization material (FGD) and fluidized bed combustion byproducts (FBC). Some CCBs such as fly ash, have pozzolanic properties and may have cementitious properties, both of which are advantageous for engineering, construction and waste remediation applications. The American Society for Testing Materials (ASTM) in ASTM C-618 has created two classifications of useful and quality coal ash, Class F ash and Class C ash. Each class of coal ash has different pozzolanic and cementitious characteristics. Coal ash can be utilized in many manufacturing, mining, agricultural, engineering, construction and waste remediation applications. These potential applications may provide a new revenue source for utilities. The profitability of these applications can, however, be limited by applicable state regulations. Prior to initiating any reuse application, a utility should ensure regulatory approval of the proposed use. Approval may be apparent from a review of state law and regulations. Often times, further regulatory analysis and consultations may be necessary.

UTILIZATION OF LOW NOx COAL COMBUSTION BY-PRODUCTS  

SciTech Connect (OSTI)

Potomac Electric Power Company (PEPCo) Class F fly ash is the first material to be worked on in this project. A head sample was taken and a screen analysis performed. Each size fraction was evaluated for LOI content. Table 1 shows the distribution of the as-received material by size and LOI content. From the data, 80% of the as-received material is finer than 400 mesh and the LOI content goes from high at coarse fractions and decreases to a low at the finest size fraction. SEM chemical analysis identified the as-received fly ash to mainly consist of silica (46%), aluminum oxide (21%), and iron in various forms (16%). The high iron content presents an extreme case as compared to other fly ash samples we have evaluated previously. Its effect on product testing applications could identify physical and chemical limitations as product testing progresses. Because of the high iron content, it was realized that magnetic separation would be incorporated into the early part of the pilot plant flowsheet to remove magnetic iron and, hopefully, reduce the total iron content. More analytical data will be presented in the next reporting period.

System analysis of nuclear-assisted syngas production from coal - article no. 042901  

SciTech Connect (OSTI)

A system analysis has been performed to assess the efficiency and carbon utilization of a nuclear-assisted coal gasification process. The nuclear reactor is a high-temperature helium-cooled reactor that is used primarily to provide power for hydrogen production via high-temperature electrolysis. The supplemental hydrogen is mixed with the outlet stream from an oxygen-blown coal gasifier to produce a hydrogen-rich gas mixture, allowing most of the carbon dioxide to be converted into carbon monoxide, with enough excess hydrogen to produce a syngas product stream with a hydrogen/carbon monoxide molar ratio of about 2:1. Oxygen for the gasifier is also provided by the high-temperature electrolysis process. The results of the analysis predict 90.5% carbon utilization with a syngas production efficiency (defined as the ratio of the heating value of the produced syngas to the sum of the heating value of the coal plus the high-temperature reactor heat input) of 64.4% at a gasifier temperature of 1866 K for the high-moisture-content lignite coal considered. Usage of lower moisture coals such as bituminous can yield carbon utilization approaching 100% and 70% syngas production efficiency.

Investigation of benefit of using coal wastes in cement production  

Science Journals Connector (OSTI)

Waste disposal in coal preparation plants leads to serious environmental problems. These wastes usually contain about 20% carbon, and the composition of the remaining ash is similar to clay. Addition of these wastes to cement clinker raw material utilises carbon as a source of energy. In this investigation, the effect of addition of these waste materials to the raw materials used in cement manufacture is studied. Ordinary type II cement and sulphoaluminate cement may be produced from the wastes. Mechanical strength, chemical and phase analysis, setting time and particle size distribution of the cement were studied. The results of the experiments show that an addition of about 3% of the coal wastes to the raw materials used in cement manufacture produces cements with good quality. Further, energy consumption may be reduced by up to 15%.

DEVELOPMENT OF CONTINUOUS SOLVENT EXTRACTION PROCESSES FOR COAL DERIVED CARBON PRODUCTS

The purpose of this DOE-funded effort is to develop continuous processes for solvent extraction of coal for the production of carbon products. These carbon products include materials used in metals smelting, especially in the aluminum and steel industries, as well as porous carbon structural material referred to as ''carbon foam'' and carbon fibers. Table 1 provides an overview of the major markets for carbon products. Current sources of materials for these processes generally rely on petroleum distillation products or coal tar distillates obtained as a byproduct of metcoke production facilities. In the former case, the American materials industry, just as the energy industry, is dependent upon foreign sources of petroleum. In the latter case, metcoke production is decreasing every year due to the combined difficulties associated with poor economics and a significant environmental burden. Thus, a significant need exists for an environmentally clean process which can used domestically obtained raw materials and which can still be very competitive economically.

Broader source: All U.S. Department of Energy (DOE) Office Webpages (Extended Search)

16, 2008 16, 2008 Innovative Coal-Based Product Bumps Petroleum Out of Equation Synthetic Binder Pitch Uses Hydrocarbons from Coal in Place of Petroleum Feedstocks WASHINGTON, DC - Through a cooperative agreement with the Office of Fossil Energy's National Energy Technology Laboratory (NETL), a team headed by West Virginia University (WVU) has developed and successfully demonstrated a synthetic binder pitch that uses hydrocarbons from coal to supplement or replace petroleum feedstocks. The new binder pitch, and similar coal-derived products, could potentially reduce America's dependence on imported oil. Binder pitch - a carbon-rich, tar-like material - is an important ingredient in making graphite rods used in electric arc furnaces for the manufacture of steel from scrap. Conventional binder pitch usually blends petroleum pitch with standard coal-tar pitch. The new synthetic pitch could replace at least 19,000 tons of conventional pitch needed each year by graphite electrode manufacturers. WVU claims that the same pitch could be used by the aluminum industry; if so, demand for the new product would be close to one million barrels per year.

Composition of the ozonolytic degradation products of the organic matter of Barzasskii sapromyxite coal  

SciTech Connect (OSTI)

The ozonization of Barzasskii sapromyxite coal in chloroform and the composition of ozonolytic degradation products were studied. Water-insoluble high-molecular-weight products were predominant among the ozonization products. A half of water-soluble substances consisted of aliphatic C{sub 5}-C{sub 12} dicarboxylic acids and benzenedicarboxylic acid derivatives. Sapromyxite has been suggested as a substitute for crude petroleum in the manufacture of motor fuels.

Integrated production/use of ultra low-ash coal, premium liquids and clean char. Technical report, September 1, 1991--November 30, 1991  

SciTech Connect (OSTI)

This integrated, multi-product approach for utilizing Illinois coal starts with the production of ultra low-ash coal and then converts it to high-vale, coal-derived, products. The ultra low-ash coal is produced by solubilizing coal in a phenolic solvent under ChemCoal{trademark} process conditions, separating the coal solution from insoluble ash, and then precipitating the clean coal by dilution of the solvent with methanol. Two major products, liquids and low-ash char, are then produced by mild gasification of the low-ash coal. The low ash-char is further upgraded to activated char, and/or an oxidized activated char which has catalytic properties. Characterization of products at each stage is part of this project.

Studies on the production of ultra-clean coal by alkali-acid leaching of low-grade coals  

SciTech Connect (OSTI)

The use of low-grade coal in thermal power stations is leading to environmental pollution due to the generation of large amounts of fly ash, bottom ash, and CO{sub 2} besides other pollutants. It is therefore important to clean the coal before using it in thermal power stations, steel plants, or cement industries etc. Physical beneficiation of coal results in only limited cleaning of coal. The increasing environmental pollution problems from the use of coal have led to the development of clean coal technologies. In fact, the clean use of coal requires the cleaning of coal to ultra low ash contents, keeping environmental norms and problems in view and the ever-growing need to increase the efficiency of coal-based power generation. Therefore this requires the adaptation of chemical cleaning techniques for cleaning the coal to obtain ultra clean coal having ultra low ash contents. Presently the reaction conditions for chemical demineralization of low-grade coal using 20% aq NaOH treatment followed by 10% H{sub 2}SO{sub 4} leaching under reflux conditions have been optimized. In order to reduce the concentration of alkali and acid used in this process of chemical demineralization of low-grade coals, stepwise, i.e., three step process of chemical demineralization of coal using 1% or 5% aq NaOH treatment followed by 1% or 5% H{sub 2}SO{sub 4} leaching has been developed, which has shown good results in demineralization of low-grade coals. In order to conserve energy, the alkali-acid leaching of coal was also carried out at room temperature, which gave good results.

Techno-economic analysis of coal gasification based co-production systems  

Science Journals Connector (OSTI)

Abstract Coal gasification based co-production systems are increasing popular in the world because they are assumed to be advantageous in energy efficiency and economic cost. However, there has been seldom researches on quantifying these advantages. In this paper, the co-prouction systems are analyzed from the technical and ecnomic point of views. During the study, the co-production system, of which the products are electricity and methanol, is modeled and simulated. For analysis, the energy analysis model and the economy analysis model are established. Results show that the co-production system has higher energy efficiency and less capital expenditure than tranditional single production systems.

Process for the production of ethylene and other hydrocarbons from coal  

SciTech Connect (OSTI)

A process is claimed for the production of substantial amounts of ethylene and other hydrocarbon compounds, such as benzene from coal. Coal is reacted with methane at a temperature in the approximate range of 500/sup 0/C to 1100/sup 0/C at a partial pressure less than about 200 psig for a period of less than 10 seconds, and preferably at a temperature of approximately 850/sup 0/C, and a partial pressure of 50 psig for a period of approximately 2 seconds. Ethylene and other hydrocarbon compounds may be separated from the product stream so produced, and the methane recycled for further production of ethylene. In another embodiment, other compounds produced, such as by-product tars, may be burned to heat the recycled methane.

Method for controlling boiling point distribution of coal liquefaction oil product  

DOE Patents [OSTI]

The relative ratio of heavy distillate to light distillate produced in a coal liquefaction process is continuously controlled by automatically and continuously controlling the ratio of heavy distillate to light distillate in a liquid solvent used to form the feed slurry to the coal liquefaction zone, and varying the weight ratio of heavy distillate to light distillate in the liquid solvent inversely with respect to the desired weight ratio of heavy distillate to light distillate in the distillate fuel oil product. The concentration of light distillate and heavy distillate in the liquid solvent is controlled by recycling predetermined amounts of light distillate and heavy distillate for admixture with feed coal to the process in accordance with the foregoing relationships. 3 figs.

An evaluation of Substitute natural gas production from different coal gasification processes based on modeling  

Science Journals Connector (OSTI)

Coal and lignite will play a significant role in the future energy production. However, the technical options for the reduction of CO2 emissions will define the extent of their share in the future energy mix. The production of synthetic or substitute natural gas (SNG) from solid fossil fuels seems to be a very attractive process: coal and lignite can be upgraded into a methane rich gas which can be transported and further used in high efficient power systems coupled with CO2 sequestration technologies. The aim of this paper is to present a modeling analysis comparison between substitute natural gas production from coal by means of allothermal steam gasification and autothermal oxygen gasification. In order to produce SNG from syngas several unit operations are required such as syngas cooling, cleaning, potential compression and, of course, methanation reactors. Finally the gas which is produced has to be conditioned i.e. removal of unwanted species, such as CO2 etc. The heat recovered from the overall process is utilized by a steam cycle, producing power. These processes were modeled with the computer software IPSEpro™. An energetic and exergetic analysis of the coal to SNG processes have been realized and compared.

Stable isotope geochemistry of coal bed and shale gas and related production waters: A review  

Science Journals Connector (OSTI)

Abstract Coal bed and shale gas can be of thermogenic, microbial or of mixed origin with the distinction made primarily on the basis of the molecular and stable isotope compositions of the gases and production waters. Methane, ethane, carbon dioxide and nitrogen are the main constituents of coal bed and shale gases, with a general lack of C2+ hydrocarbon species in gases produced from shallow levels and more mature coals and shales. Evidence for the presence of microbial gas include ?13C–CH4 values less than ? 50‰, covariation of the isotope compositions of gases and production water, carbon and hydrogen isotope fractionations consistent with microbial processes, and positive ?13C values of dissolved inorganic carbon in production waters. The CO2-reduction pathway is distinguished from acetate/methyl-type fermentation by somewhat lower ?13C–CH4 and higher ?D–CH4, but can also have overlapping values depending on the openness of the microbial system and the extent of substrate depletion. Crossplots of ?13C–CH4 versus ?13C–CO2 and ?D–CH4 versus ?13C–H2O may provide a better indication of the origin of the gases and the dominant metabolic pathway than the absolute carbon and hydrogen isotope compositions of methane. In the majority of cases, microbial coal bed and shale gases have carbon and hydrogen isotope fractionations close to those expected for CO2 reduction. Primary thermogenic gases have ?13C–CH4 values greater than ? 50‰, and ?13C values that systematically increase from C1 to C4 and define a relatively straight line when plotted against reciprocal carbon number. Although coals and disseminated organic matter in shales represent a continuum as hydrocarbon source rocks, current data suggest a divergence between these two rock types at the high maturity end. In deep basin shale gas, reversals or rollovers in molecular and isotopic compositions are increasingly reported in what is effectively a closed shale system as opposed to the relative openness in coal measure environments. Detailed geochemical studies of coal bed and shale gas and related production waters are essential to determine not only gas origins but also the dominant methanogenic pathway in the case of microbial gases.

Production and Optimization of Direct Coal Liquefaction derived Low Carbon-Footprint Transportation Fuels  

SciTech Connect (OSTI)

This report summarizes works conducted under DOE Contract No. DE-FC26-05NT42448. The work scope was divided into two categories - (a) experimental program to pretreat and refine a coal derived syncrude sample to meet transportation fuels requirements; (b) system analysis of a commercial scale direct coal liquefaction facility. The coal syncrude was derived from a bituminous coal by Headwaters CTL, while the refining study was carried out under a subcontract to Axens North America. The system analysis included H{sub 2} production cost via six different options, conceptual process design, utilities requirements, CO{sub 2} emission and overall plant economy. As part of the system analysis, impact of various H{sub 2} production options was evaluated. For consistence the comparison was carried out using the DOE H2A model. However, assumptions in the model were updated using Headwaters database. Results of Tier 2 jet fuel specifications evaluation by the Fuels & Energy Branch, US Air Force Research Laboratory (AFRL/RZPF) located at Wright Patterson Air Force Base (Ohio) are also discussed in this report.

ADVANCED MULTI-PRODUCT COAL UTILIZATION BY-PRODUCT PROCESSING PLANT  

SciTech Connect (OSTI)

The objective of the project is to build a multi-product ash beneficiation plant at Kentucky Utilities 2,200-MW Ghent Generating Station, located in Carroll County, Kentucky. This part of the study includes the examination of the feedstocks for the beneficiation plant. The ash, as produced by the plant, and that stored in the lower pond were examined. The ash produced by the plant was found to be highly variable as the plant consumes high and low sulfur bituminous coal, in Units 1 and 2 and a mixture of subbituminous and bituminous coal in Units 3 and 4. The ash produced reflected this consisting of an iron-rich ({approx}24%, Fe{sub 2}O{sub 3}), aluminum rich ({approx}29% Al{sub 2}O{sub 3}) and high calcium (6%-7%, CaO) ash, respectively. The LOI of the ash typically was in the range of 5.5% to 6.5%, but individual samples ranged from 1% to almost 9%. The lower pond at Ghent is a substantial body, covering more than 100 acres, with a volume that exceeds 200 million cubic feet. The sedimentation, stratigraphy and resource assessment of the in place ash was investigated with vibracoring and three-dimensional, computer-modeling techniques. Thirteen cores to depths reaching nearly 40 feet, were retrieved, logged in the field and transported to the lab for a series of analyses for particle size, loss on ignition, petrography, x-ray diffraction, and x-ray fluorescence. Collected data were processed using ArcViewGIS, Rockware, and Microsoft Excel to create three-dimensional, layered iso-grade maps, as well as stratigraphic columns and profiles, and reserve estimations. The ash in the pond was projected to exceed 7 million tons and contain over 1.5 million tons of coarse carbon, and 1.8 million tons of fine (<10 {micro}m) glassy pozzolanic material. The size, quality and consistency of the ponded material suggests that it is the better feedstock for the beneficiation plant.

China's Coal: Demand, Constraints, and Externalities  

SciTech Connect (OSTI)

This study analyzes China's coal industry by focusing on four related areas. First, data are reviewed to identify the major drivers of historical and future coal demand. Second, resource constraints and transport bottlenecks are analyzed to evaluate demand and growth scenarios. The third area assesses the physical requirements of substituting coal demand growth with other primary energy forms. Finally, the study examines the carbon- and environmental implications of China's past and future coal consumption. There are three sections that address these areas by identifying particular characteristics of China's coal industry, quantifying factors driving demand, and analyzing supply scenarios: (1) reviews the range of Chinese and international estimates of remaining coal reserves and resources as well as key characteristics of China's coal industry including historical production, resource requirements, and prices; (2) quantifies the largest drivers of coal usage to produce a bottom-up reference projection of 2025 coal demand; and (3) analyzes coal supply constraints, substitution options, and environmental externalities. Finally, the last section presents conclusions on the role of coal in China's ongoing energy and economic development. China has been, is, and will continue to be a coal-powered economy. In 2007 Chinese coal production contained more energy than total Middle Eastern oil production. The rapid growth of coal demand after 2001 created supply strains and bottlenecks that raise questions about sustainability. Urbanization, heavy industrial growth, and increasing per-capita income are the primary interrelated drivers of rising coal usage. In 2007, the power sector, iron and steel, and cement production accounted for 66% of coal consumption. Power generation is becoming more efficient, but even extensive roll-out of the highest efficiency units would save only 14% of projected 2025 coal demand for the power sector. A new wedge of future coal consumption is likely to come from the burgeoning coal-liquefaction and chemicals industries. If coal to chemicals capacity reaches 70 million tonnes and coal-to-liquids capacity reaches 60 million tonnes, coal feedstock requirements would add an additional 450 million tonnes by 2025. Even with more efficient growth among these drivers, China's annual coal demand is expected to reach 3.9 to 4.3 billion tonnes by 2025. Central government support for nuclear and renewable energy has not reversed China's growing dependence on coal for primary energy. Substitution is a matter of scale: offsetting one year of recent coal demand growth of 200 million tonnes would require 107 billion cubic meters of natural gas (compared to 2007 growth of 13 BCM), 48 GW of nuclear (compared to 2007 growth of 2 GW), or 86 GW of hydropower capacity (compared to 2007 growth of 16 GW). Ongoing dependence on coal reduces China's ability to mitigate carbon dioxide emissions growth. If coal demand remains on a high growth path, carbon dioxide emissions from coal combustion alone would exceed total US energy-related carbon emissions by 2010. Within China's coal-dominated energy system, domestic transportation has emerged as the largest bottleneck for coal industry growth and is likely to remain a constraint to further expansion. China has a low proportion of high-quality reserves, but is producing its best coal first. Declining quality will further strain production and transport capacity. Furthermore, transporting coal to users has overloaded the train system and dramatically increased truck use, raising transportation oil demand. Growing international imports have helped to offset domestic transport bottlenecks. In the long term, import demand is likely to exceed 200 million tonnes by 2025, significantly impacting regional markets.

DEVELOPMENT OF CONTINUOUS SOLVENT EXTRACTION PROCESSES FOR COAL DERIVED CARBON PRODUCTS  

SciTech Connect (OSTI)

The purpose of this DOE-funded effort is to develop continuous processes for solvent extraction of coal for the production of carbon products. These carbon products include materials used in metals smelting, especially in the aluminum and steel industries, as well as porous carbon structural material referred to as ''carbon foam'' and carbon fibers. A process has been developed which results in high quality binder pitch suitable for use in graphite electrodes or carbon anodes. A detailed description of the protocol is given by Clendenin. Briefly, aromatic heavy oils are hydro-treated under mild conditions in order to increase their ability to dissolve coal. An example of an aromatic heavy oil is Koppers Carbon Black Base (CBB) oil. CBB oil has been found to be an effective solvent and acceptably low cost (i.e., significantly below the market price for binder pitch, or about $280 per ton at the time of this writing). It is also possible to use solvents derived from hydrotreated coal and avoid reliance on coke oven recovery products completely if so desired.

WABASH RIVER INTEGRATED METHANOL AND POWER PRODUCTION FROM CLEAN COAL TECHNOLOGIES (IMPPCCT)  

SciTech Connect (OSTI)

The Wabash River Integrated Methanol and Power Production from Clean Coal Technologies (IMPPCCT) project is evaluating integrated electrical power generation and methanol production through clean coal technologies. The project is conducted by a multi-industry team lead previously by Gasification Engineering Corporation (GEC). The project is now under the leadership of ConocoPhillips Company (COP) after it acquired GEC and the E-Gas{trademark} gasification technology from Global Energy in July 2003. The Phase I of this project was supported by Air Products and Chemicals, Inc., Dow Chemical Company, Dow Corning Corporation, Methanex Corporation, and Siemens Westinghouse Power Corporation, while the Phase II is supported by Gas Technology Institute, TDA Research, Inc., and Nucon International, Inc. The two project phases planned for execution include: (1) Feasibility study and conceptual design for an integrated demonstration facility at Global Energy's existing Wabash River Energy Limited (WREL) plant in West Terre Haute, Indiana, and for a fence-line commercial embodiment plants (CEP) operated at Dow Chemical or Dow Corning chemical plant locations (2) Research, development, and testing (RD&T) to define any technology gaps or critical design and integration issues. The WREL facility was designed, constructed, and operated under a project selected and co-funded under the Round IV of the United States Department of Energy's (DOE's) Clean Coal Technology Program. In this project, coal and/or other solid fuel feedstocks are gasified in an oxygen-blown, entrained-flow gasifier with continuous slag removal and a dry particulate removal system. The resulting product synthesis gas is used to fuel a combustion turbine generator whose exhaust is integrated with a heat recovery steam generator to drive a refurbished steam turbine generator. The gasifier uses technology initially developed by The Dow Chemical Company (the Destec Gasification Process), and now acquired and offered commercially by COP as the E-GAS{trademark} technology. In a joint effort with the DOE, a Cooperative Agreement was awarded under the Early Entrance Coproduction Plant (EECP) solicitation. GEC, and now COP and the industrial partners are investigating the use of synthesis gas produced by the E-GAS{trademark} technology in a coproduction environment to enhance the efficiency and productivity of solid fuel gasification combined cycle power plants. The objectives of this effort are to determine the feasibility of an EECP located at a specific site which produces some combination of electric power (or heat), fuels, and/or chemicals from synthesis gas derived from coal, or, coal in combination with some other carbonaceous feedstock. The project's intended result is to provide the necessary technical, economic, and environmental information that will be needed to move the EECP forward to detailed design, construction, and operation by industry.

Methods for the speciation and determination of arsenic and selenium in coal combustion products  

SciTech Connect (OSTI)

Methods of sample preparation for the determination of total selenium, and selenite, selenate, arsenite, and arsenate in coal fly ash materials were evaluated. The measurement methods use atomic spectroscopy for the determination of total concentrations and ion chromatography (IC) for the determination of individual ionic species. Sample preparation procedures which minimize the loss or alteration of the species of interest was explored and defined. The utility of the sample preparation methods can be sample dependent, so caution is advised in their use. IC conditions were established for the determination in extract solutions of selenite, selenate, arsenite, and arsenate with minimal interference from common anions.

Chemical structure of coal tar during devolatilization  

SciTech Connect (OSTI)

Enormous progress has been made in coal pyrolysis research during the last two decades. Models of coal devolatilization have progressed from simple rate expressions based on total mass release to empirical relationships based on the elemental composition of the parent coal to models that attempt to describe the macromolecular network of the coal. In the last several years, advancements in chemical analysis techniques have allowed quantitative investigations of the chemical structure of both coal and its pyrolysis products, including the nature of the resulting char. A prominent research goal is to accurately predict the rates, yields, and products of devolatilization from measurements of the parent coal structure. The prediction of nitrogen species evolved during devolatilization is of current interest. These goals necessitate modeling the reaction processes on the molecular scale, with activation energies that relate to chemical bond breaking rather than to the mass of products released from the coal. Solid-state {sup 13}C NMR spectroscopy has proven particularly useful in obtaining average values of chemical structure features of coal and char, while liquid phase {sup 1}H NMR spectroscopy has been used to determine some of the chemical features of coal tar. Pyridine extract residues from coal and partially-pyrolyzed coal chars have also been analyzed by solid-state {sup 13}C NMR spectroscopy, and the extracts have been analyzed by {sup 1}H NMR spectroscopy.

Development of a Hydrogasification Process for Co-Production of Substitute Natural Gas (SNG) and Electric Power from Western Coals  

SciTech Connect (OSTI)

This report presents the results of the research and development conducted on an Advanced Hydrogasification Process (AHP) conceived and developed by Arizona Public Service Company (APS) under U.S. Department of Energy (DOE) contract: DE-FC26-06NT42759 for Substitute Natural Gas (SNG) production from western coal. A double-wall (i.e., a hydrogasification contained within a pressure shell) down-flow hydrogasification reactor was designed, engineered, constructed, commissioned and operated by APS, Phoenix, AZ. The reactor is ASME-certified under Section VIII with a rating of 1150 pounds per square inch gage (psig) maximum allowable working pressure at 1950 degrees Fahrenheit ({degrees}F). The reaction zone had a 1.75 inch inner diameter and 13 feet length. The initial testing of a sub-bituminous coal demonstrated ~ 50% carbon conversion and ~10% methane yield in the product gas under 1625{degrees}F, 1000 psig pressure, with a 11 seconds (s) residence time, and 0.4 hydrogen-to-coal mass ratio. Liquid by-products mainly contained Benzene, Toluene, Xylene (BTX) and tar. Char collected from the bottom of the reactor had 9000-British thermal units per pound (Btu/lb) heating value. A three-dimensional (3D) computational fluid dynamic model simulation of the hydrodynamics around the reactor head was utilized to design the nozzles for injecting the hydrogen into the gasifier to optimize gas-solid mixing to achieve improved carbon conversion. The report also presents the evaluation of using algae for carbon dioxide (CO{sub 2}) management and biofuel production. Nannochloropsis, Selenastrum and Scenedesmus were determined to be the best algae strains for the project purpose and were studied in an outdoor system which included a 6-meter (6M) radius cultivator with a total surface area of 113 square meters (m{sup 2}) and a total culture volume between 10,000 to 15,000 liters (L); a CO{sub 2} on-demand feeding system; an on-line data collection system for temperature, pH, Photosynthetically Activate Radiation (PAR) and dissolved oxygen (DO); and a ~2 gallons per minute (gpm) algae culture dewatering system. Among the three algae strains, Scenedesmus showed the most tolerance to temperature and irradiance conditions in Phoenix and the best self-settling characteristics. Experimental findings and operational strategies determined through these tests guided the operation of the algae cultivation system for the scale-up study. Effect of power plant flue gas, especially heavy metals, on algae growth and biomass adsorption were evaluated as well.

Product Characterization for Entrained Flow Coal/Biomass Co-Gasification  

SciTech Connect (OSTI)

The U.S. Department of Energy‘s National Energy Technology Laboratory (DOE NETL) is exploring affordable technologies and processes to convert domestic coal and biomass resources to high-quality liquid hydrocarbon fuels. This interest is primarily motivated by the need to increase energy security and reduce greenhouse gas emissions in the United States. Gasification technologies represent clean, flexible and efficient conversion pathways to utilize coal and biomass resources. Substantial experience and knowledge had been developed worldwide on gasification of either coal or biomass. However, reliable data on effects of blending various biomass fuels with coal during gasification process and resulting syngas composition are lacking. In this project, GE Global Research performed a complete characterization of the gas, liquid and solid products that result from the co-gasification of coal/biomass mixtures. This work was performed using a bench-scale gasifier (BSG) and a pilot-scale entrained flow gasifier (EFG). This project focused on comprehensive characterization of the products from gasifying coal/biomass mixtures in a high-temperature, high-pressure entrained flow gasifier. Results from this project provide guidance on appropriate gas clean-up systems and optimization of operating parameters needed to develop and commercialize gasification technologies. GE‘s bench-scale test facility provided the bulk of high-fidelity quantitative data under temperature, heating rate, and residence time conditions closely matching those of commercial oxygen-blown entrained flow gasifiers. Energy and Environmental Research Center (EERC) pilot-scale test facility provided focused high temperature and pressure tests at entrained flow gasifier conditions. Accurate matching of syngas time-temperature history during cooling ensured that complex species interactions including homogeneous and heterogeneous processes such as particle nucleation, coagulation, surface condensation, and gas-phase reactions were properly reproduced and lead to representative syngas composition at the syngas cooler outlet. The experimental work leveraged other ongoing GE R&D efforts such as biomass gasification and dry feeding systems projects. Experimental data obtained under this project were used to provide guidance on the appropriate clean-up system(s) and operating parameters to coal and biomass combinations beyond those evaluated under this project.

Coal fly ash–carbide lime bricks: An environment friendly building product  

Science Journals Connector (OSTI)

Abstract Coal fly ash and carbide lime are industrial by-products of coal combustion in thermal power plants and of manufacture of acetylene gas, respectively, available in profusion in southern Brazil. Research has been carried out to search for possible use of such materials to produce environmental friendly bricks that have high compressive strength. This study aims to evaluate strength controlling parameters of coal fly ash–carbide lime mixtures, as well as to show that porosity/carbide lime (?/Lv) ratio (corresponding to porosity divided by the volumetric carbide lime content) can be used to predict compressive strength (qu). The controlling parameters evaluated here are carbide lime content, porosity, curing temperature, curing time and porosity/carbide lime ratio. A number of unconfined compression tests were carried out. The results show that a power function adapts better the relation qu versus ?/Lv, in which Lv is adjusted by an exponent (in this case 0.11) for all coal fly ash–carbide lime mixtures studied. Equations that control the compressive strength for each curing period and curing temperature examined can be formulated using this unique ratio. Preferred strategies for varying ranges of qu are also proposed based on the energy required for heating, considering distinct curing periods and temperatures.

Prevention of trace and major element leaching from coal combustion products by hydrothermally-treated coal ash  

SciTech Connect (OSTI)

The most important structural components of coal ash obtained by coal combustion in 'Nikola Tesla A' power plant located near Belgrade (Serbia) are amorphous alumosilicate, alpha-quartz, and mullite. The phase composition of coal ash can be altered to obtain zeolite type NaA that crystallizes in a narrow crystallization field (SiO{sub 2}/Al{sub 2}O{sub 3}; Na{sub 2}O/SiO{sub 2}; H{sub 2}O/Na{sub 2}O ratios). Basic properties (crystallization degree, chemical composition, the energy of activation) of obtained zeolites were established. Coal ash extracts treated with obtained ion-exchange material showed that zeolites obtained from coal ash were able to reduce the amounts of iron, chromium, nickel, zinc, copper, lead, and manganese in ash extracts, thus proving its potential in preventing pollution from dump effluent waters.

Matrix Shrinkage and Swelling Effects on Economics of Enhanced Coalbed Methane Production and CO2 Sequestration in Coal  

SciTech Connect (OSTI)

Increases in CO2 levels in the atmosphere and their contributions to global climate change have been a major concern. It has been shown that CO2 injection can enhance the methane recovery from coal. Accordingly, sequestration costs can be partially offset by the value added product. Indeed, coal seam sequestration may be profitable, particularly with the introduction of incentives for CO2 sequestration. Hence, carbon dioxide sequestration in unmineable coals is a very attractive option, not only for environmental reasons, but also for possible economic benefits. Darcy flow through cleats is an important transport mechanism in coal. Cleat compression and permeability changes due to gas sorption desorption, changes of effective stress, and matrix swelling and shrinkage introduce a high level of complexity into the feasibility of a coal sequestration project. The economic effects of carbon dioxide-induced swelling on permeabilities and injectivities has received little (if any) detailed attention. Carbon dioxide and methane have different swelling effects on coal. In this work, the Palmer-Mansoori model for coal shrinkage and permeability increases during primary methane production was re-written to also account for coal swelling caused by carbon dioxide sorption. The generalized model was added to PSU-COALCOMP, a dual porosity reservoir simulator for primary and enhanced coalbed methane production. A standard five-spot of vertical wells and representative coal properties for Appalachian coals were used.[1] Simulations and sensitivity analyses were performed with the modified simulator for nine different parameters, including coal seam and operational parameters and economic criteria. The coal properties and operating parameters that were varied included Young’s modulus, Poisson’s ratio, the cleat porosity, and the injection pressure. The economic variables included CH4 price, CO2 cost, CO2 credit, water disposal cost, and interest rate. Net present value analyses of the simulation results included profits due to methane production, and potential incentives for CO2 sequestered. This work shows that for some coal-property values, the compressibility and cleat porosity of coal may be more important than more purely economic criteria.

Volumetric strain associated with methane desorption and its impact on coalbed gas production from deep coal seams  

SciTech Connect (OSTI)

For deep coal seams, significant reservoir pressure drawdown is required to promote gas desorption because of the Langmuir-type isotherm that typifies coals. Hence, a large permeability decline may occur because of pressure drawdown and the resulting increase in effective stress, depending on coal properties and the stress field during production. However, the permeability decline can potentially be offset by the permeability enhancement caused by the matrix shrinkage associated with methane desorption. The predictability of varying permeability is critical for coalbed gas exploration and production-well management. We have investigated quantitatively the effects of reservoir pressure and sorption-induced volumetric strain on coal-seam permeability with constraints from the adsorption isotherm and associated volumetric strain measured on a Cretaceous Mesaverde Group coal (Piceance basin) and derived a stress-dependent permeability model. Our results suggest that the favorable coal properties that can result in less permeability reduction during earlier production and an earlier strong permeability rebound (increase in permeability caused by coal shrinkage) with methane desorption include (1) large bulk or Young's modulus; (2) large adsorption or Langmuir volume; (3) high Langmuir pressure; (4) high initial permeability and dense cleat spacing; and (5) low initial reservoir pressure and high in-situ gas content. Permeability variation with gas production is further dependent on the orientation of the coal seam, the reservoir stress field, and the cleat structure. Well completion with injection of N2 and displacement of CH{sub 4} only results in short-term enhancement of permeability and does not promote the overall gas production for the coal studied.

Split and collectorless flotation to medium coking coal fines for multi-product zero waste concept  

Science Journals Connector (OSTI)

The medium coking coal fines of ? 0.5 mm from Jharia coal field were taken for this investigation. The release analysis of the composite coal reveals that yield is very low at 10.0% ash, about 25% at 14% ash and 50% at 17% ash level. The low yield is caused by the presence of high ash finer fraction. The size-wise ash analysis of ? 0.5 mm coal indicated that ? 0.5 + 0.15 mm fraction contains less ash than ? 0.15 mm fraction. Thus, the composite feed was split into ? 0.5 + 0.15 mm and ? 0.15 mm fractions and subjected to flotation separately. The low ash bearing fraction (? 0.5 + 0.15 mm) was subjected to two stages collectorless flotation to achieve the concentrate with 10% ash. The cleaner concentrate (18.9%) with 10% ash was recovered which has an application in metallurgical industries. The concentrate of 30.2% yield with 12.5% ash could be achieved in one stage collectorless flotation which is suitable for use in coke making as sweetener. As the ? 0.15 mm fraction contains relatively high ash, collector aided flotation using sodium silicate was performed to get a concentrate of 23.6% yield with about 17% ash. The blending of this product with cleaner tail obtained from ? 0.5 + 0.15 mm produces about 35.0% yield with 17% ash and that can be utilized for coke making. The reject from the two fractions can be used for conventional thermal power plant or cement industries using a 23.5% ash after one stage collector aided flotation and the final tailings produced content ash of 61.6% can be used for fluidization combustion bed (FBC). This eventually leads to complete utilization of coal.

Production of cements from Illinois coal ash. Technical report, September 1, 1995--November 30, 1995  

SciTech Connect (OSTI)

The objective of this program is to convert Illinois coal combustion residues, such as fly ash, bottom ash, and boiler slag, into novel cementitious materials for use in the construction industry. Currently only about 30% of the 5 million tons of these coal combustion residues generated in Illinois each year are utilized, mainly as aggregate. These residues are composed largely Of SiO{sub 2}, Al{sub 2}O{sub 3}, Fe{sub 2}O{sub 3}, MgO, and CaO, which are also the major components of cement. The process being developed in this program will use the residues directly in the manufacture of cement products. Therefore, a much larger amount of residues can be utilized. To achieve the above objective, in the first phase (current year) samples of coal combustion residues will be blended and mixed, as needed, with a lime or cement kiln dust (CKD) to adjust the CaO composition. Six mixtures will be melted in a laboratory-scale furnace at CTL. The resulting products will then be tested for cementitious properties. Two preliminary blends have been tested. One blend used fly ash with limestone, while the other used fly ash with CKD. Each blend was melted and then quenched, and the resulting product samples were ground to a specific surface area similar to portland cement. Cementitious properties of these product samples were evaluated by compression testing of 1-inch cube specimens. The specimens were formed out of cement paste where a certain percentage of the cement paste is displaced by one of the sample products. The specimens were cured for 24 hours at 55{degrees}C and 100% relative humidity. The specimens made with the product samples obtained 84 and 89% of the strength of a pure portland cement control cube. For comparison, similar (pozzolanic) materials in standard concrete practice are required to have a compressive strength of at least 75% of that of the control.

Coal availability and coal recoverability studies: A reevaluation of the United States coal resources  

SciTech Connect (OSTI)

A cooperative program between the US Geological Survey (USGS), US Bureau of Mines (USBM), and geological agencies of the principal coal-bearing States has began to (1) identify and delineate current major land-use/environmental and technologic/geologic restrictions on the availability of coal resources; (2) estimate the amount of remaining coal resources that may be available for development under those constraints; (3) estimate the amount that can be economically extracted and marketed; and (4) identify possible social and economic disruptions that could occur within local and regional economies as coal resources are exhausted. Within major coal-producing regions, selected 7.5-minute quadrangles are chosen to represent variations in geology, topography, and land-use patterns so that results might be extrapolated throughout the entire region. After identifying State and Federal coal mining regulations, USGS and State scientists consult with local coal-industry engineers, geologists, and mine operators to ascertain local mining practices. Coal bed outcrop lines, current and past mined areas, and restrictions to mining are plotted at 1:24,000 scale and geographic information system (GIS) techniques are applied. Coal availability/recoverability studies have expanded into the central and northern Appalachian regions, Illinois basin, and Powder River basin. The first four basins, with 75% of current US coal production, should be completed by 1998. The total program is designed to cover 150 quadrangles from within the 11 major coal regions of the US. These 11 regions represent 97% of current US coal production. Planned project completion is 2001.

Development of a coal combustion product (CCP) database system. Final report  

SciTech Connect (OSTI)

Nearly 90 million tons of coal combustion products (CCPs) are produced annually in the United States. The value of CCPs is well established by research and commercial practice; however, only 25% of these products are utilized. The objective of this project was to develop a computer program containing a database of advanced analytical and comprehensive engineering information on CCPs, accessible through a user-friendly interface. Version 1.0 of the ACAA CCP Data Manager was specifically designed to: perform multiple-criteria queries to produce a set of sample for in-depth study; view and print standard test reports, such as C618 reports; compare and contrast analytical results in graphs and tables; graph utilization information by application and region; and save data to a file for use in other computer applications, such as spreadsheet programs. The program was designed to contain descriptive information about a given CCP sample, including sample formation data (material type, sample location, fuel type, collection device etc.), combustion system design data (steam generator type, furnace type, SO{sub 2} and NO{sub x} control information, ash-handling configurations), test data (chemical, mineralogical, and physical characterization data), and utilization potential of the CCP. The location of the plant is identified by region. The database has been initially populated with information on over 800 CCP samples, taken from the Coal Ash Resources Research Consortium (CARRC). An installation package and user`s guide was developed for unlimited distribution by the American Coal Ash Association (ACAA).

Wabash River Integrated Methanol and Power Production from Clean Coal Technologies (IMPPCCT)  

SciTech Connect (OSTI)

The Wabash River Integrated Methanol and Power Production from Clean Coal Technologies (IMPPCCT) project was established to evaluate integrated electrical power generation and methanol production through clean coal technologies. The project was under the leadership of ConocoPhillips Company (COP), after it acquired Gasification Engineering Corporation (GEC) and the E-Gas gasification technology from Global Energy Inc. in July 2003. The project has completed both Phase 1 and Phase 2 of development. The two project phases include the following: (1) Feasibility study and conceptual design for an integrated demonstration facility at SG Solutions LLC (SGS), previously the Wabash River Energy Limited, Gasification Facility located in West Terre Haute, Indiana, and for a fence-line commercial embodiment plant (CEP) operated at the Dow Chemical Company or Dow Corning Corporation chemical plant locations. (2) Research, development, and testing (RD&T) to define any technology gaps or critical design and integration issues. Phase 1 of this project was supported by a multi-industry team consisting of Air Products and Chemicals, Inc., The Dow Chemical Company, Dow Corning Corporation, Methanex Corporation, and Siemens Westinghouse Power Corporation, while Phase 2 was supported by Gas Technology Institute, TDA Research Inc., and Nucon International, Inc. The SGS integrated gasification combined cycle (IGCC) facility was designed, constructed, and operated under a project selected and co-funded under the Round IV of the United States Department of Energy's (DOE's) Clean Coal Technology Program. In this project, coal and/or other carbonaceous fuel feedstocks are gasified in an oxygen-blown, entrained-flow gasifier with continuous slag removal and a dry particulate removal system. The resulting product synthesis gas (syngas) is used to fuel a combustion turbine generator whose exhaust is integrated with a heat recovery steam generator to drive a refurbished steam turbine generator. The gasifier uses technology initially developed by The Dow Chemical Company (the Destec Gasification Process), and now acquired and offered commercially by COP as the E-Gas technology. In a joint effort with the DOE, a Cooperative Agreement was awarded under the Early Entrance Coproduction Plant (EECP) solicitation. GEC, and later COP and the industrial partners investigated the use of syngas produced by the E-Gas technology in a coproduction environment to enhance the efficiency and productivity of solid fuel gasification combined cycle power plants. The objectives of this effort were to determine the feasibility of an EECP located at a specific site which produces some combination of electric power (or heat), fuels, and/or chemicals from syngas derived from coal, or, coal in combination with some other carbonaceous feedstock. The intended result of the project was to provide the necessary technical, economic, and environmental information that would be needed to move the EECP forward to detailed design, construction, and operation by industry. The EECP study conducted in Phase 1 of the IMPPCCT Project confirmed that the concept for the integration of gasification-based (E-Gas) electricity generation from coal and/or petroleum coke and methanol production (Liquid Phase Methanol or LPMEOH{trademark}) processes was feasible for the coproduction of power and chemicals. The results indicated that while there were minimal integration issues that impact the deployment of an IMPPCCT CEP, the major concern was the removal of sulfur and other trace contaminants, which are known methanol catalyst poisons, from the syngas. However, economic concerns in the domestic methanol market which is driven by periodic low natural gas prices and cheap offshore supplies limit the commercial viability of this more capital intensive concept. The objective of Phase 2 was to conduct RD&T as outlined in the Phase 1 RD&T Plan to enhance the development and commercial acceptance of coproduction technology. Studies were designed to address the technical concerns that would mak

DEVELOPMENT OF CONTINUOUS SOLVENT EXTRACTION PROCESSES FOR COAL DERIVED CARBON PRODUCTS  

SciTech Connect (OSTI)

This NETL sponsored effort seeks to develop continuous technologies for the production of carbon products, which may be thought of as the heavier products currently produced from refining of crude petroleum and coal tars obtained from metallurgical grade coke ovens. This effort took binder grade pitch, produced from liquefaction of West Virginia bituminous grade coal, all the way to commercial demonstration in a state of the art arc furnace. Other products, such as crude oil, anode grade coke and metallurgical grade coke were demonstrated successfully at the bench scale. The technology developed herein diverged from the previous state of the art in direct liquefaction (also referred to as the Bergius process), in two major respects. First, direct liquefaction was accomplished with less than a percent of hydrogen per unit mass of product, or about 3 pound per barrel or less. By contrast, other variants of the Bergius process require the use of 15 pounds or more of hydrogen per barrel, resulting in an inherent materials cost. Second, the conventional Bergius process requires high pressure, in the range of 1500 psig to 3000 psig. The WVU process variant has been carried out at pressures below 400 psig, a significant difference. Thanks mainly to DOE sponsorship, the WVU process has been licensed to a Canadian Company, Quantex Energy Inc, with a commercial demonstration unit plant scheduled to be erected in 2011.

DEVELOPMENT OF CONTINUOUS SOLVENT EXTRACTION PROCESSES FOR COAL DERIVED CARBON PRODUCTS  

SciTech Connect (OSTI)

The purpose of this DOE-funded effort is to develop continuous processes for solvent extraction of coal for the production of carbon products. The largest applications are those which support metals smelting, such as anodes for aluminum smelting and electrodes for arc furnaces. Other carbon products include materials used in creating fuels for the Direct Carbon Fuel Cell, metals smelting, especially in the aluminum and steel industries, as well as porous carbon structural material referred to as ''carbon foam'' and carbon fibers. During this reporting period, efforts have focused on the development of carbon electrodes for Direct Carbon Fuel Cells (DCFC), and on carbon foam composites used in ballistic armor, as well as the hydrotreatment of solvents used in the basic solvent extraction process. A major goal is the production of 1500 pounds of binder pitch, corresponding to about 3000 pounds of hydrotreated solvent.

Coal combustion products in Europe - sustainable raw materials for the construction industry  

Science Journals Connector (OSTI)

The production of coal combustion products (CCPs) in all the European member states is estimated to be about 100 million tonnes. The utilisation of CCPs is well established in some European countries, based on long term experience and technical as well as environmental benefits. The CCPs are mainly utilised in the building material and construction industry as a replacement for natural resources. By their utilisation, they help to reduce energy demand and greenhouse gas emissions to atmosphere for mining and production of products which are replaced and to save natural resources. By this, the use of CCPs contributes to the sustainability of construction materials. Furthermore, the majority of the CCPs is produced to meet certain requirements of standards or other specifications with respect to utilisation in certain areas. The standards and specifications are subject to regular revision by CEN or national authorities.

Resource Assessment & Production Testing for Coal Bed Methane in the Illinois Basin  

SciTech Connect (OSTI)

In order to assess the economic coal bed methane potential of the Illinois Basin, the geological surveys of Illinois, Indiana and Kentucky performed a geological assessment of their respective parts of the Illinois Basin. A considerable effort went into generating cumulative coal thickness and bed structure maps to identify target areas for exploratory drilling. Following this, the first project well was drilled in White County, Illinois in October 2003. Eight additional wells were subsequently drilled in Indiana (3) and Kentucky (5) during 2004 and 2005. In addition, a five spot pilot completion program was started with three wells being completed. Gas contents were found to be variable, but generally higher than indicated by historical data. Gas contents of more than 300 scf/ton were recovered from one of the bore holes in Kentucky. Collectively, our findings indicate that the Illinois Basin represents a potentially large source of economic coal bed methane. Additional exploration will be required to refine gas contents and the economics of potential production.

This report describes management planning, work breakdown structure development, and feasibility study activities by the IMPPCCT consortium in support of the first project phase. Project planning activities have been completed, and a project timeline and task list has been generated. Requirements for an economic model to evaluate the West Terre Haute implementation and for other commercial implementations are being defined. Specifications for methanol product and availability of local feedstocks for potential commercial embodiment plant sites have been defined. The WREL facility is a project selected and co-funded under the fifth phase solicitation of the U.S. Department of Energy's Clean Coal Technology Program. In this project, coal and/or other solid fuel feedstocks are gasified in an oxygen-blown, entrained-flow gasifier with continuous slag removal and a dry particulate removal system. The resulting product synthesis gas is used to fuel a combustion turbine generator whose exhaust is integrated with a heat recovery steam generator to drive a refurbished steam turbine generator. The gasifier uses technology initially developed by The Dow Chemical Company (the Destec Gasification Process), and now offered commercially by Global Energy, Inc., as the E-GAS{trademark} technology. In a joint effort with the U.S. Department of Energy, working under a Cooperative Agreement Award from the ''Early Entrance Coproduction Plant'' (EECP) initiative, the GEC and an Industrial Consortia are investigating the application of synthesis gas from the E-GAS{trademark} technology to a coproduction environment to enhance the efficiency and productivity of solid fuel gasification combined cycle power plants. The objectives of this effort are to determine the feasibility of an EECP located at a specific site which produces some combination of electric power (or heat), fuels, and/or chemicals from synthesis gas derived from coal, or, coal in combination with some other carbonaceous feedstock. The project's intended result is to provide the necessary technical, economic, and environmental information that will be needed to move the EECP forward to detailed design, construction, and operation by industry.

Task 1.13 - Data Collection and Database Development for Clean Coal Technology By-Product Characteristics and Management Practices  

SciTech Connect (OSTI)

U.S. Department of Energy Federal Energy Technology Center-Morgantown (DOE FETC) efforts in the areas of fossil fuels and clean coal technology (CCT) have included involvement with both conventional and advanced process coal conversion by-products. In 1993, DOE submitted a Report to Congress on "Barriers to the Increased Utilization of Coal Combustion Desulfurization Byproducts by Governmental and Commercial Sectors" that provided an outline of activities to remove the barriers identified in the report. DOE charged itself with participation in this process, and the work proposed in this document facilitates DOE's response to its own recommendations for action. The work reflects DOE's commitment to the coal combustion by-product (CCB) industry, to the advancement of clean coal technology, and to cooperation with other government agencies. Information from DOE projects and commercial endeavors in fluidized-bed combustion (FBC) and coal gasification is the focus of this task. The primary goal is to provide an easily accessible compilation of characterization information on the by-products from these processes to government agencies and industry to facilitate sound regulatory and management decisions. Additional written documentation will facilitate the preparation of an updated final version of background information collected for DOE in preparation of the Report to Congress on barriers to CCB utilization.

WABASH RIVER INTEGRATED METHANOL AND POWER PRODUCTION FROM CLEAN COAL TECHNOLOGIES (IMPPCCT)  

SciTech Connect (OSTI)

The Wabash River Integrated Methanol and Power Production from Clean Coal Technologies (IMPPCCT) project is evaluating integrated electrical power generation and methanol production through clean coal technologies. The project is conducted by a multi-industry team lead by Gasification Engineering Corporation (GEC), and supported by Air Products and Chemicals, Inc., Dow Chemical Company, Dow Corning Corporation, Methanex Corporation, and Siemens Westinghouse Power Corporation. Three project phases are planned for execution, including: (1) Feasibility study and conceptual design for an integrated demonstration facility, and for fence-line commercial embodiment plants (CEP) operated at Dow Chemical or Dow Corning chemical plant locations (2) Research, development, and testing (RD&T) to define any technology gaps or critical design and integration issues (3) Engineering design and financing plan to install an integrated commercial demonstration facility at the existing Wabash River Energy Limited (WREL) plant in West Terre Haute, Indiana. The WREL facility is a project selected and co-funded under the Round IV of the United States Department of Energy's (DOE's) Clean Coal Technology Program. In this project, coal and/or other solid fuel feedstocks are gasified in an oxygen-blown, entrained-flow gasifier with continuous slag removal and a dry particulate removal system. The resulting product synthesis gas is used to fuel a combustion turbine generator whose exhaust is integrated with a heat recovery steam generator to drive a refurbished steam turbine generator. The gasifier uses technology initially developed by The Dow Chemical Company (the Destec Gasification Process), and now offered commercially by Global Energy, Inc., parent company of GEC and WREL, as the E-GAS{trademark} technology. In a joint effort with the DOE, a Cooperative Agreement was awarded under the Early Entrance Coproduction Plant (EECP) solicitation. GEC and an Industrial Consortium are investigating the use of synthesis gas produced by the E-GAS{trademark} technology in a coproduction environment to enhance the efficiency and productivity of solid fuel gasification combined cycle power plants. The objectives of this effort are to determine the feasibility of an EECP located at a specific site which produces some combination of electric power (or heat), fuels, and/or chemicals from synthesis gas derived from coal, or, coal in combination with some other carbonaceous feedstock. The project's intended result is to provide the necessary technical, economic, and environmental information that will be needed to move the EECP forward to detailed design, construction, and operation by industry. During the reporting period, effort continues on identifying potential technologies for removing contaminants from synthesis gas to the level required by methanol synthesis. A liquid phase Claus process and a direct sulfur oxidation process were evaluated. Preliminary discussion was held with interested parties on cooperating on RD&T in Phase II of the project. Also, significant progress was made during the period in the submission of project deliverables. A meeting was held at DOE's National Energy Technology Laboratory in Morgantown between GEC and the DOE IMPPCCT Project Manager on the status of the project, and reached an agreement on the best way to wrap up Phase I and transition into the Phase II RD&T. Potential projects for the Phase II, cost, and fund availability were also discussed.

DEVELOPMENT OF CONTINUOUS SOLVENT EXTRACTION PROCESSES FOR COAL DERIVED CARBON PRODUCTS  

SciTech Connect (OSTI)

The purpose of this DOE-funded effort is to develop continuous processes for solvent extraction of coal for the production of carbon products. The largest applications are those which support metals smelting, such as anodes for aluminum smelting and electrodes for arc furnaces. Other carbon products include materials used in creating fuels for the Direct Carbon Fuel Cell, metals smelting, especially in the aluminum and steel industries, as well as porous carbon structural material referred to as ''carbon foam'' and carbon fibers. During this reporting period, coking and composite fabrication continued using coal-derived samples. These samples were tested in direct carbon fuel cells. Methodology was refined for determining the aromatic character of hydro treated liquid, based on Nuclear Magnetic Resonance (NMR) and Fourier Transform Infrared (FTIR). Tests at GrafTech International showed that binder pitches produced using the WVU solvent extraction protocol can result in acceptable graphite electrodes for use in arc furnaces. These tests were made at the pilot scale.

Improving process performances in coal gasification for power and synfuel production  

SciTech Connect (OSTI)

This paper is aimed at developing process alternatives of conventional coal gasification. A number of possibilities are presented, simulated, and discussed in order to improve the process performances, to avoid the use of pure oxygen, and to reduce the overall CO{sub 2} emissions. The different process configurations considered include both power production, by means of an integrated gasification combined cycle (IGCC) plant, and synfuel production, by means of Fischer-Tropsch (FT) synthesis. The basic idea is to thermally couple a gasifier, fed with coal and steam, and a combustor where coal is burnt with air, thus overcoming the need of expensive pure oxygen as a feedstock. As a result, no or little nitrogen is present in the syngas produced by the gasifier; the required heat is transferred by using an inert solid as the carrier, which is circulated between the two modules. First, a thermodynamic study of the dual-bed gasification is carried out. Then a dual-bed gasification process is simulated by Aspen Plus, and the efficiency and overall CO{sub 2} emissions of the process are calculated and compared with a conventional gasification with oxygen. Eventually, the scheme with two reactors (gasifier-combustor) is coupled with an IGCC process. The simulation of this plant is compared with that of a conventional IGCC, where the gasifier is fed by high purity oxygen. According to the newly proposed configuration, the global plant efficiency increases by 27.9% and the CO{sub 2} emissions decrease by 21.8%, with respect to the performances of a conventional IGCC process. 29 refs., 7 figs., 5 tabs.

Coal: evolving supply and demand in world seaborne steam coal trade. [1975 to 1985; forecasting to 1995  

SciTech Connect (OSTI)

This paper describes the evolution of world seaborne steam coal trade since 1975. It highlights current trends and the historic and present sources of supply and demand and discusses selected factors that may affect future world trade patterns. It concludes with a general discussion on the prospects for United States participation in the growing world markets for steam coal. Worldwide seaborne steam coal trade is linked very closely to the generation of electricity and industrial use of process heat in cement and other manufacturing plants. The main factors that influence this trade are: economic growth, electricity demand, indigenous coal production (and degree of protection from lower cost coal imports), and the delivered costs of coal relative to other substitutable fuels. It may be of interest to know how these factors have changed seaborne steam coal trade in the past twelve years. In 1970, the total world use of steam coal was about two billion short tons. International trade in steam coal was only 80 million tons or about 4% of the total. Seaborne trade accounted for about 30% of international trade, or about 25 million tons. In 1982, the latest year for which good statistics are available, total world use of steam coal was about 3.6 billion tons. Seaborne steam coal trade was 110 million tons which is about 3% of the total and 37% of the international trade. 11 figs., 2 tabs.

Production and screening of carbon products precursors from coal. Quarterly technical progress report and key personnel staffing report No. 6, April 1, 1996--June 30, 1996  

SciTech Connect (OSTI)

The main goal of this program is to demonstrate the utility of coal extracts from the West Virginia University (WVU) extraction process as suitable base raw materials for the carbon products encompassed by the Carbon Products Consortium (CPC) team. This quarterly report covers activities during the period from April 1, 1996 through June 30, 1996. The first year of the project ended in February, 1996; however, the WVU research effort has continued on a no-cost extension of the original contract. Samples have been supplied to CPC participants so they could conduct their portions of the project as contracted through ORNL. Progress reports are presented for the following tasks: project planning and administration; consortium administration and reporting; coal extraction; technical/economic evaluation of WVU extraction process; and technology transfer. Previous work has shown that the WVU coal extraction process coupled with hydrotreatment, does have the potential for producing suitable base raw materials for carbon products. Current effort, therefore, involved the screening and evaluation of extracts produced by the WVU Group and recommending appropriate materials for scaleup for subsequent evaluation by Consortium Team members. As part of this program, the activation of the coal extraction residues was investigated for the purpose of producing a useful active carbon. A further task, which was started towards the end of the program, was to fabricate a small graphite artifact using Coke derived from coal extract as the filler and the coal extract itself as a binder. The results of these studies are summarized in this report.

WABASH RIVER IMPPCCT, INTEGRATED METHANOL AND POWER PRODUCTION FROM CLEAN COAL TECHNOLOGIES  

SciTech Connect (OSTI)

In a joint effort with the U.S. Department of Energy, working under a Cooperative Agreement Award from the ''Early Entrance Coproduction Plant'' (EECP) initiative, the Gasification Engineering Corporation and an Industrial Consortium are investigating the application of synthesis gas from the E-GAS{trademark} technology to a coproduction environment to enhance the efficiency and productivity of solid fuel gasification combined cycle power plants. The objectives of this effort are to determine the feasibility of an Early Entrance Coproduction Plant located at a specific site which produces some combination of electric power (or heat), fuels, and/or chemicals from synthesis gas derived from coal, or, coal in combination with some other carbonaceous feedstock. The project's intended result is to provide the necessary technical, financial, and environmental information that will be needed to move the EECP forward to detailed design, construction, and operation by industry. The Wabash River Integrated Methanol and Power Production from Clean Coal Technologies (IMPPCCT) project is evaluating integrated electrical power generation and methanol production through clean coal technologies. The project is conducted by a multi-industry team lead by Gasification Engineering Corporation (GEC), and supported by Air Products and Chemicals Inc., The Dow Chemical Company, Dow Corning Corporation, Methanex Corporation, and Siemens Westinghouse Power Corporation. Three project phases are planned for execution, including: (1) Feasibility Study and conceptual design for an integrated demonstration facility and for fence-line commercial plants operated at The Dow Chemical Company or Dow Corning Corporation chemical plant locations (i.e. the Commercial Embodiment Plant or CEP) (2) Research, development, and testing to address any technology gaps or critical design and integration issues (3) Engineering design and financing plan to install an integrated commercial demonstration facility at the existing Wabash River Energy Ltd., plant in West Terre Haute, Indiana. During the reporting period work was furthered to support the development of capital and operating cost estimates associated with the installation of liquid or gas phase methanol synthesis technology in a Commercial Embodiment Plant (CEP) utilizing the six cases previously defined. In addition, continued development of the plant economic model was accomplished by providing combined cycle performance data. Performance and emission estimates for gas turbine combined cycles was based on revised methanol purge gas information. The economic model was used to evaluate project returns with various market conditions and plant configurations and was refined to correct earlier flaws. Updated power price projections were obtained and incorporated in the model. Sensitivity studies show that break-even methanol prices which provide a 12% return are 47-54 cents/gallon for plant scenarios using $1.25/MM Btu coal, and about 40 cents/gallon for most of the scenarios with $0.50/MM Btu petroleum coke as the fuel source. One exception is a high power price and production case which could be economically attractive at 30 cents/gallon methanol. This case was explored in more detail, but includes power costs predicated on natural gas prices at the 95th percentile of expected price distributions. In this case, the breakeven methanol price is highly sensitive to the required project return rate, payback period, and plant on-line time. These sensitivities result mainly from the high capital investment required for the CEP facility ({approx}$500MM for a single train IGCC-methanol synthesis plant). Finally, during the reporting period the Defense Contractor Audit Agency successfully executed an accounting audit of Global Energy Inc. for data accumulated over the first year of the IMPPCCT project under the Cooperative Agreement.

Coal preparation: The essential clean coal technology  

SciTech Connect (OSTI)

This chapter is a brief introduction to a broad topic which has many highly specialized areas. The aim is to summarize the essential elements of coal preparation and illustrate its important role in facilitating the clean use of coal. Conventional coal preparation is the essential first step in ensuring the economic and environmentally acceptable use of coal. The aim of coal preparation is to produce saleable products of consistent, specified quality which satisfy customer requirements while optimizing the utilization of the coal resource. Coal preparation covers all aspects of preparing coal for the market. It includes size reduction, blending and homogenization and, most importantly, the process of physical beneficiation or washing, which involves separation of undesirable mineral matter from the coal substance itself. Coal preparation can be performed at different levels of sophistication and cost. The degree of coal preparation required is decided by considering the quality of the raw coal, transport costs and, in particular, the coal quality specified by the consumer. However, the cost of coal beneficiation rises rapidly with the complexity of the process and some coal is lost with the waste matter because of process inefficiencies, therefore each situation requires individual study to determine the optimum coal preparation strategy. The necessary expertise is available within APEC countries such as Australia. Coals destined for iron making are almost always highly beneficiated. Physical beneficiation is mostly confined to the higher rank, hard coals, but all other aspects of coal preparation can be applied to subbituminous and lignitic coals to improve their utilization. Also, there are some interesting developments aimed specifically at reducing the water content of lower rank coals.

Production of cements from Illinois coal ash. Final technical report, September 1, 1995--August 31, 1996  

SciTech Connect (OSTI)

The objective of this program is to convert Illinois coal combustion residues, such as fly ash, bottom ash, and boiler slag, into novel cementitious materials for use in the construction industry. These residues are composed largely of SiO{sub 2}, Al{sub 2}O{sub 3}, Fe{sub 2}O{sub 3}, MgO, and CaO, which are also the major components of cement. Since the residues are used as an integral component of the cement and not just as additives to concrete, larger amounts of the residues can be utilized. The process uses submerged combustion to melt blends of coal combustion residues with lime, clay, and/or sand. The submerged combustion melter utilizes natural gas-oxidant firing directly into a molten bath to provide efficient melting of mineral-like materials. Use of this melter for cement production has many advantages over rotary kilns including very little, if any, grinding of the feed material, very low emissions, and compact size. During the first year of the program, samples of coal combustion residues were blended and mixed, as needed; with lime, clay, and/or sand to adjust the composition. Six mixtures, three with fly ash and three with bottom ash, were melted in a laboratory-scale furnace. The resultant products were used in mortar cubes and bars which were subjected to ASTM standard tests of cementitious properties. In the hydraulic activity test, mortar cubes were found to have a strength comparable to standard mortar cements. In the compressive strength test, mortar cubes were found to have strengths that exceeded ASTM blended cement performance specifications. In the ASR expansion test, mortar bars were subjected to alkali-silica reaction-induced expansion, which is a problem for siliceous aggregate-based concretes that are exposed to moisture. The mortar bars made with the products inhibited 85 to 97% of this expansion. These results show that residue-based products have an excellent potential as ASR-preventing additions in concretes.

Method and apparatus for the selective separation of gaseous coal gasification products by pressure swing adsorption  

SciTech Connect (OSTI)

Bulk separation of the gaseous components of multi-component gases provided by the gasification of coal including hydrogen, carbon monoxide, methane, and acid gases (carbon dioxide plus hydrogen sulfide) are selectively adsorbed by a pressure swing adsorption technique using activated carbon, zeolite or a combination thereof as the adsorbent. By charging a column containing the adsorbent with a gas mixture and pressurizing the column to a pressure sufficient to cause the adsorption of the gases and then reducing the partial pressure of the contents of the column, the gases are selectively and sequentially desorbed. Hydrogen, the least absorbable gas of the gaseous mixture, is the first gas to be desorbed and is removed from the column in a co-current direction followed by the carbon monoxide, hydrogen and methane. With the pressure in the column reduced to about atmospheric pressure the column is evacuated in a countercurrent direction to remove the acid gases from the column. The present invention is particularly advantageous as a producer of high parity hydrogen from gaseous products of coal gasification and as an acid gas scrubber.

Production of High-Hydrogen Content Coal-Derived Liquids [Part 2 of 3  

SciTech Connect (OSTI)

The primary goal of this project has been to evaluate and compare the effect of the intrinsic differences between cobalt (Co) and iron (Fe) catalysts for Fischer-Tropsch (FT) synthesis using coal-derived syngas. Crude oil, especially heavy, high-sulfur crude, is no longer the appropriate source for the additional, or marginal, amounts of middle-distillate fuels needed to meet growing US and world demand for diesel and jet fuels. Only about 1/3 of the marginal crude oil barrel can be made into diesel and jet fuels. The remaining 2/3 contributes further to global surpluses of by-products. FT can produce these needed marginal, low-sulfur middle-distillate fuels more efficiently, with less environmental impact, and from abundant US domestic resources. Cobalt FT catalyst is more efficient, and less expensive overall, than iron FT catalyst. Mechanisms of cobalt FT catalyst functioning, and poisoning, have been elucidated. Each of these primary findings is amplified by several secondary findings, and these are presented, and verified in detail. The most effective step the United States can take to begin building toward improved long-term national energy security, and to reduce dependence, over time, on imported crude oil from unfriendly and increasingly unstable areas of the world, is to begin producing additional, or marginal amounts of, middle-distillate-type fuels, such as ultralow sulfur diesel (ULSD) and jet fuel (not gasoline) from US domestic resources other than petroleum. FT synthesis of these middle distillate fuels offers the advantage of being able to use abundant and affordable US coal and biomass as the primary feedstocks. Use of the cobalt FT catalyst system has been shown conclusively to be more effective and less expensive than the use of iron FT catalyst with syngas derived from coal, or from coal and biomass combined. This finding is demonstrated in detail for the initial case of a relatively small FT plant of about 2000 barrels per day based upon coal and biomass. The primary feature of such a plant, in the current situation in which no commercial FT plants are operating in the US, is that it requires a relatively modest capital investment, meaning that such a plant could actually be built, operated, and replicated in the near term. This is in contrast to the several-billion dollar investment, and accompanying risk, that would be required for a plant of more than an order of magnitude greater capacity, which has been referred to in the technical literature on fuel production as the capacity required to be considered "commercial-scale." The effects of more than ten different potential poisons for cobalt FT catalyst have been studied extensively and in detail using laboratory continuous-stirred tank reactors (CSTRs) and bottled laboratory syngas "spiked" with precisely controlled amounts of the poisons, typically at the levels of 10s or 100s of parts per billion. This data set has been generated and interpreted by world-renowned experts on FT catalysis at the University of Kentucky Center for Applied Energy Research (UK-CAER), and has enabled unprecedented insight regarding the many molecular-scale mechanisms that can play a role in the "poisoning" of cobalt FT catalyst.

DEVELOPMENT OF CONTINUOUS SOLVENT EXTRACTION PROCESSES FOR COAL DERIVED CARBON PRODUCTS  

SciTech Connect (OSTI)

The purpose of this DOE-funded effort is to develop continuous processes for solvent extraction of coal for the production of carbon products. These carbon products include materials used in metals smelting, especially in the aluminum and steel industries, as well as porous carbon structural material referred to as ''carbon foam'' and carbon fibers. There are a number of parameters which are important for the production of acceptable cokes, including purity, structure, density, electrical resistivity, thermal conductivity etc. From the standpoint of a manufacturer of graphite electrodes such as GrafTech, one of the most important parameters is coefficient of thermal expansion (CTE). Because GrafTech material is usually fully graphitized (i.e., heat treated at 3100 C), very high purity is automatically achieved. The degree of graphitization controls properties such as CTE, electrical resistivity, thermal conductivity, and density. Thus it is usually possible to correlate these properties using a single parameter. CTE has proven to be a useful index for the quality of coke. Pure graphite actually has a slightly negative coefficient of thermal expansion, whereas more disordered carbon has a positive coefficient.

Environmental chamber measurements of mercury flux from coal utilization by-products  

SciTech Connect (OSTI)

An environmental chamber was constructed to measure the mercury flux from coal utilization by-product (CUB) samples. Samples of fly ash, FGD gypsum, and wallboard made from FGD gypsum were tested under both dark and illuminated conditions with or without the addition of water to the sample. Mercury releases varied widely, with 7-day experiment averages ranging from -6.8 to 73 ng/m2 h for the fly ash samples and -5.2 to 335 ng/m2 h for the FGD/wallboard samples. Initial mercury content, fly ash type, and light exposure had no observable consistent effects on the mercury flux. For the fly ash samples, the effect of a mercury control technology was to decrease the emission. For three of the four pairs of FGD gypsum and wallboard samples, the wallboard sample released less (or absorbed more) mercury than the gypsum.

Economical production of transportation fuels from coal, natural gas, and other carbonaceous feedstocks  

SciTech Connect (OSTI)

The Nation`s economy and security will continue to be vitally linked to an efficient transportation system of air, rail, and highway vehicles that depend on a continuous supply of liquid fuels at a reasonable price and with characteristics that can help the vehicle manufacturers meet increasingly strict environmental regulations. However, an analysis of US oil production and demand shows that, between now and 2015, a significant increase in imported oil will be needed to meet transportation fuel requirements. One element of an overall Department of Energy`s (DOE) strategy to address this energy security issue while helping meet emissions requirements is to produce premium transportation fuels from non-petroleum feedstocks, such as coal, natural gas, and biomass, via Fischer-Tropsch (F-T) and other synthesis gas conversion technologies.

Economic analysis of coal-based polygeneration system for methanol and power production  

Science Journals Connector (OSTI)

Polygeneration system for chemical and power co-production has been regarded as one of promising technologies to use fossil fuel more efficiently and cleanly. In this paper the thermodynamic and economic performances of three types of coal-based polygeneration system were investigated and the influence of energy saving of oxygenation systems on system economic performance was revealed. The primary cost saving ratio (PCS) is presented as a criterion, which represents the cost saving of polygeneration system compared with the single-product systems with the same products outputs, to evaluate economic advantages of polygeneration system. As a result, the system, adopting un-reacted syngas partly recycled to the methanol synthesis reactor and without the shift process, can get the optimal PCS of 11.8%, which results from the trade-off between the installed capital cost saving and the energy saving effects on the cost saving, and represents the optimal coupling relationship among chemical conversion, energy utilization and economic performance. And both of fuel price and the level of equipment capital cost affect on PCS faintly. This paper provides an evaluation method for polygeneration systems based on both technical and economic viewpoints.

The mixture subsequently travels along a moving conveyor belt together with the rest of the charge materials. The addition of up to 2% resin-bearing waste materials to the coal charge has not had any significant effect on the strength properties of the coke.

Mercury and Air Toxic Element Impacts of Coal Combustion By-Product Disposal and Utilizaton  

SciTech Connect (OSTI)

The University of North Dakota Energy & Environmental Research Center (EERC) conducted a multiyear study to evaluate the impact of mercury and other air toxic elements (ATEs) on the management of coal combustion by-products (CCBs). The ATEs evaluated in this project were arsenic, cadmium, chromium, lead, nickel, and selenium. The study included laboratory tasks to develop measurement techniques for mercury and ATE releases, sample characterization, and release experiments. A field task was also performed to measure mercury releases at a field site. Samples of fly ash and flue gas desulfurization (FGD) materials were collected preferentially from full-scale coal-fired power plants operating both without and with mercury control technologies in place. In some cases, samples from pilot- and bench-scale emission control tests were included in the laboratory studies. Several sets of 'paired' baseline and test fly ash and FGD materials collected during full-scale mercury emission control tests were also included in laboratory evaluations. Samples from mercury emission control tests all contained activated carbon (AC) and some also incorporated a sorbent-enhancing agent (EA). Laboratory release experiments focused on measuring releases of mercury under conditions designed to simulate CCB exposure to water, ambient-temperature air, elevated temperatures, and microbes in both wet and dry conditions. Results of laboratory evaluations indicated that: (1) Mercury and sometimes selenium are collected with AC used for mercury emission control and, therefore, present at higher concentrations than samples collected without mercury emission controls present. (2) Mercury is stable on CCBs collected from systems both without and with mercury emission controls present under most conditions tested, with the exception of vapor-phase releases of mercury exposed to elevated temperatures. (3) The presence of carbon either from added AC or from unburned coal can result in mercury being sorbed onto the CCB when exposed to ambient-temperature air. The environmental performance of the mercury captured on AC used as a sorbent for mercury emission control technologies indicated that current CCB management options will continue to be sufficiently protective of the environment, with the potential exception of exposure to elevated temperatures. The environmental performance of the other ATEs investigated indicated that current management options will be appropriate to the CCBs produced using AC in mercury emission controls.

While U.S. coal production is down 7 percent this year due in part to utilities switching to low-priced natural gas to generate electricity, American coal is still finding plenty of buyers in overseas markets. U.S. coal exports are expected to hit a record 125 million tons in 2012, the U.S. Energy Information Administration says in its new monthly short-term energy outlook. Coal exports are expected to decline in 2013, primarily because of continuing economic weakness in Europe, lower international coal prices, and higher coal production in Asia. However, U.S. coal exports next year are still expected to top 100 million tons for the third year in a row

The economical production of alcohol fuels from coal-derived synthesis gas: Case studies, design, and economics  

SciTech Connect (OSTI)

This project is a combination of process simulation and catalyst development aimed at identifying the most economical method for converting coal to syngas to linear higher alcohols to be used as oxygenated fuel additives. There are two tasks. The goal of Task 1 is to discover, study, and evaluate novel heterogeneous catalytic systems for the production of oxygenated fuel enhancers from synthesis gas, and to explore, analytically and on the bench scale, novel reactor and process concepts for use in converting syngas to liquid fuel products. The goal of Task 2 is to simulate, by computer, energy efficient and economically efficient processes for converting coal to energy (fuel alcohols and/or power). The primary focus is to convert syngas to fuel alcohols. This report contains results from Task 2. The first step for Task 2 was to develop computer simulations of alternative coal to syngas to linear higher alcohol processes, to evaluate and compare the economics and energy efficiency of these alternative processes, and to make a preliminary determination as to the most attractive process configuration. A benefit of this approach is that simulations will be debugged and available for use when Task 1 results are available. Seven cases were developed using different gasifier technologies, different methods for altering the H{sub 2}/CO ratio of the syngas to the desired 1.1/1, and with the higher alcohol fuel additives as primary products and as by-products of a power generation facility. Texaco, Shell, and Lurgi gasifier designs were used to test gasifying coal. Steam reforming of natural gas, sour gas shift conversion, or pressure swing adsorption were used to alter the H{sub 2}/CO ratio of the syngas. In addition, a case using only natural gas was prepared to compare coal and natural gas as a source of syngas.

Hydrogen production by high-temperature steam gasification of biomass and coal  

SciTech Connect (OSTI)

High-temperature steam gasification of paper, yellow pine woodchips, and Pittsburgh bituminous coal was investigated in a batch-type flow reactor at temperatures in the range of 700 to 1,200{sup o}C at two different ratios of steam to feedstock molar ratios. Hydrogen yield of 54.7% for paper, 60.2% for woodchips, and 57.8% for coal was achieved on a dry basis, with a steam flow rate of 6.3 g/min at steam temperature of 1,200{sup o}C. Yield of both the hydrogen and carbon monoxide increased while carbon dioxide and methane decreased with the increase in gasification temperature. A 10-fold reduction in tar residue was obtained at high-temperature steam gasification, compared to low temperatures. Steam and gasification temperature affects the composition of the syngas produced. Higher steam-to-feedstock molar ratio had negligible effect on the amount of hydrogen produced in the syngas in the fixed-batch type of reactor. Gasification temperature can be used to control the amounts of hydrogen or methane produced from the gasification process. This also provides mean to control the ratio of hydrogen to CO in the syngas, which can then be processed to produce liquid hydrocarbon fuel since the liquid fuel production requires an optimum ratio between hydrogen and CO. The syngas produced can be further processed to produce pure hydrogen. Biomass fuels are good source of renewable fuels to produce hydrogen or liquid fuels using controlled steam gasification.

Advanced coal technology by-products: Long-term results from landfill test cells and their implications for reuse or disposal applications  

SciTech Connect (OSTI)

New air pollution regulations under the 1991 Clean Air Act and other legislation are motivating continued development and implementation, of cleaner, more efficient processes for converting coal to electrical power. These clean coal processes produce solid by-products which differ in important respects from conventional pulverized coal combustion ash. Clean coal by-products` contain both residual sorbent and captured SO{sub 2} control products, as well as the mineral component of the coal. The Department of Energy/Morgantown Energy Technology Center has contracted Radian Corporation to construct and monitor landfill test cells with a several different advanced coal combustion by-products at three locations around the US; data from these sites provide a unique picture of the long-term field behavior of clean coal combustion by-products. The field testing sites were located in western Colorado, northern Ohio, and central Illinois. Fluidized bed combustion and lime injection residues are characterized by high lime and calcium sulfate contents` contributed by reacted and unreacted sorbent materials, and produce an leachate, when wetted. Compared with conventional coal fly ash, the clean coal technology ashes have been noted for potential difficulties when wetted, including corrosivity, heat generation, cementation, and swelling on hydration. On the other hand, the high lime content and chemical reactivity of clean coal residues offer potential benefits in reuse as a cementitious material.The results of three years of data collection suggest a fairly consistent pattern of behavior for the calcium-based dry sorbent systems involved in the project, despite differences in the initial of the by-products, differences in the methods of placement, and differences in climate at the test sites.

Extensive data on the coal resources, characteristics, demand and supply, coal production and plans for coal utilization to meet the energy needs in the countries of the Pacific Basin and Asia have been gathered. Two databases have been prepared based on this information which are compatible with the database on domestic coals available at NCTDC, PETC on coal resources and characteristics. Coal technologies and coal preparation methods currently in use in the Pacific Basin and Asia have also been addressed. In the second phase of this project, an assessment of the information obtained will be conducted and, wherever possible, this data will be compared with domestic data on coals and coal conversion practices so as to highlight similarities or differences. High quality and useful data will be enumerated in the form of graphs, tables and matrices for quick review. Conclusions from this data will depict work areas of potential mutual interest and areas of technology transfer. US products and services which can be exported will be emphasized.

Advanced Multi-Product Coal Utilization By-Product Processing Plant  

SciTech Connect (OSTI)

The objective of the project is to build a multi-product ash beneficiation plant at Kentucky Utilities 2,200-MW Ghent Generating Station, located in Carroll County, Kentucky. This part of the study includes the examination of the feedstocks for the beneficiation plant. The ash, as produced by the plant, and that stored in the lower pond were examined. Filter media candidates were evaluated for dewatering the ultrafine ash (UFA) product. Media candidates were selected based on manufacturer recommendations and evaluated using standard batch filtration techniques. A final media was selected; 901F, a multifilament polypropylene. While this media would provide adequate solids capture and cake moisture, the use of flocculants would be necessary to enable adequate filter throughput. Several flocculant chemistries were also evaluated and it was determined that polyethylene oxide (PEO) at a dosage of 5 ppm (slurry basis) would be the most suitable in terms of both settling rate and clarity. PEO was evaluated on a continuous vacuum filter using 901F media. The optimum cycle time was found to be 1.25 minutes which provided a 305% moisture cake, 85% solids capture with a throughput of 115 lbs dry solids per hour and a dry cake rate of 25 lb/ft2/hr. Increasing cycle time not did not reduce cake moisture or increase throughput. A mobile demonstration unit has been designed and constructed for field demonstration. The continuous test unit will be operated at the Ghent site and will evaluate three processing configurations while producing sufficient products to facilitate thorough product testing. The test unit incorporates all of the unit processes that will be used in the commercial design and is self sufficient with respect to water, electricity and processing capabilities.

Powder River Basin coalbed methane: The USGS role in investigating this ultimate clean coal by-product  

SciTech Connect (OSTI)

For the past few decades, the Fort Union Formation in the Powder River Basin has supplied the Nation with comparatively clean low ash and low sulfur coal. However, within the past few years, coalbed methane from the same Fort Union coal has become an important energy by-product. The recently completed US Geological Survey coal resource assessment of the Fort Union coal beds and zones in the northern Rocky Mountains and Great Plains (Fort Union Coal Assessment Team, 1999) has added useful information to coalbed methane exploration and development in the Powder River Basin in Wyoming and Montana. Coalbed methane exploration and development in the Powder River Basin has rapidly accelerated in the past three years. During this time more than 800 wells have been drilled and recent operator forecasts projected more than 5,000 additional wells to be drilled over the next few years. Development of shallow (less than 1,000 ft. deep) Fort Union coal-bed methane is confined to Campbell and Sheridan Counties, Wyoming, and Big Horn County, Montana. The purpose of this paper is to report on the US Geological Survey's role on a cooperative coalbed methane project with the US Bureau of Land Management (BLM), Wyoming Reservoir Management Group and several gas operators. This paper will also discuss the methodology that the USGS and the BLM will be utilizing for analysis and evaluation of coalbed methane reservoirs in the Powder River Basin. The USGS and BLM need additional information of coalbed methane reservoirs to accomplish their respective resource evaluation and management missions.

Comparing solar PV (photovoltaic) with coal-fired electricity production in the centralized network of South Africa  

Science Journals Connector (OSTI)

Abstract South Africa has a highly centralized network, in which almost all electricity is produced in Mpumalanga and transmitted throughout South Africa. In the case of the Western Cape, electricity has to be transmitted over 800–1370 km. This generates losses and entails high transmission costs. Investments in additional production and transmission capacity are needed to cope with the growing demand. Although there is a large potential for solar energy in South Africa, investments are lacking while large investments in new coal-fired power plants are being executed. These coal power plants do not only increase the need for heavier transmission infrastructure, but also have a higher CO2 emission level and a higher pressure on water reserves. This paper performs a more comprehensive cost-analysis between solar energy production and coal production facilities, to make a more elaborate picture of which technologies are more plausible to foresee in the growing demand of electricity. The current centralized electricity infrastructure makes the investment in large production facilities more likely. However, it should be questioned if the investment in large centralized solar parks will be more beneficial than the investments by consumers in smaller solar PV facilities on site.

RESOURCE ASSESSMENT & PRODUCTION TESTING FOR COAL BED METHANE IN THE ILLINOIS BASIN  

SciTech Connect (OSTI)

The geological surveys of Illinois, Indiana and Kentucky have completed the initial geologic assessment of their respective parts of the Illinois Basin. Cumulative thickness maps have been generated and target areas for drilling have been selected. The first well in the Illinois area of the Illinois Basin coal bed methane project was drilled in White County, Illinois in October 2003. This well was cored in the major coal interval from the Danville to the Davis Coals and provided a broad spectrum of samples for further analyses. Sixteen coal samples and three black shale samples were taken from these cores for canister desorption tests and were the subject of analyses that were completed over the following months, including desorbed gas volume, gas chemical and isotope composition, coal proximate, calorific content and sulfur analyses. Drilling programs in Indiana and Kentucky are expected to begin shortly.

Refined methods for the evaluation of coal resources, quantum leaps in productivity  

SciTech Connect (OSTI)

Studies of coal resource evaluations have been constantly refined since the inception of the Joint Coal Availability Project between the Kentucky Geological Survey and the U.S. Geological Survey in the mid 1980's. Originally geological, environmental, social and technical data was collected and analyzed on individual 7.5 minute quadrangles (areas of 50 to 60 square miles). Mineable coal beds were correlated using the best available data and map and mining information accuracy were closely scrutinized. Advancements in Geographical Information Systems (GIS) and the development of regional databases have allowed the US GS to model the geology and mining restrictions in the same detail, but, for much larger areas coal fields and basins, than in the past. This paper will discuss the GIS programs, methodologies, and computer hardware used in the coal evaluations, and results of Illinois, Powder River, and San Juan Basins and Wasatch Plateau studies.

SciTech Connect (OSTI)

Under the cooperative agreement with DOE, the Research and Development Department of CONSOL Energy (CONSOL R&D), teamed with Universal Aggregates, LLC, to conduct a systematic study of the durability of aggregates manufactured using a variety of flue gas desulfurization (FGD), fluidized-bed combustion (FBC) and fly ash specimens with different chemical and physical properties and under different freeze/thaw, wet/dry and long-term natural weathering conditions. The objectives of the study are to establish the relationships among the durability and characteristics of FGD material, FBC ash and fly ash, and to identify the causes of durability problems, and, ultimately, to increase the utilization of FGD material, FBC ash and fly ash as a construction material. Manufactured aggregates made from FGD material, FBC ash and fly ash, and products made from those manufactured aggregates were used in the study. The project is divided into the following activities: sample collection and characterization; characterization and preparation of manufactured aggregates; determination of durability characteristics of manufactured aggregates; preparation and determination of durability characteristics of manufactured aggregate products; and data evaluation and reporting.

Effects of matrix shrinkage and swelling on the economics of enhanced-coalbed-methane production and CO{sub 2} sequestration in coal  

SciTech Connect (OSTI)

In this work, the Palmer-Mansoori model for coal shrinkage and permeability increases during primary methane production was rewritten to also account for coal swelling caused by CO{sub 2} sorption. The generalized model was added to a compositional, dual porosity coalbed-methane reservoir simulator for primary (CBM) and ECBM production. A standard five-spot of vertical wells and representative coal properties for Appalachian coals was used. Simulations and sensitivity analyses were performed with the modified simulator for nine different parameters, including coal seam and operational parameters and economic criteria. The coal properties and operating parameters that were varied included Young's modulus, Poisson's ratio, cleat porosity, and injection pressure. The economic variables included CH{sub 4}, price, Col Cost, CO{sub 2} credit, water disposal cost, and interest rate. Net-present value (NPV) analyses of the simulation results included profits resulting from CH{sub 4}, production and potential incentives for sequestered CO{sub 2}, This work shows that for some coal seams, the combination of compressibility, cleat porosity, and shrinkage/swelling of the coal may have a significant impact on project economics.

Coal-Derived Warm Syngas Purification and CO2 Capture-Assisted Methane Production  

SciTech Connect (OSTI)

Gasifier-derived syngas from coal has many applications in the area of catalytic transformation to fuels and chemicals. Raw syngas must be treated to remove a number of impurities that would otherwise poison the synthesis catalysts. Inorganic impurities include alkali salts, chloride, sulfur compounds, heavy metals, ammonia, and various P, As, Sb, and Se- containing compounds. Systems comprising multiple sorbent and catalytic beds have been developed for the removal of impurities from gasified coal using a warm cleanup approach. This approach has the potential to be more economic than the currently available acid gas removal (AGR) approaches and improves upon currently available processes that do not provide the level of impurity removal that is required for catalytic synthesis application. Gasification also lends itself much more readily to the capture of CO2, important in the regulation and control of greenhouse gas emissions. CO2 capture material was developed and in this study was demonstrated to assist in methane production from the purified syngas. Simultaneous CO2 sorption enhances the CO methanation reaction through relaxation of thermodynamic constraint, thus providing economic benefit rather than simply consisting of an add-on cost for carbon capture and release. Molten and pre-molten LiNaKCO3 can promote MgO and MgO-based double salts to capture CO2 with high cycling capacity. A stable cycling CO2 capacity up to 13 mmol/g was demonstrated. This capture material was specifically developed in this study to operate in the same temperature range and therefore integrate effectively with warm gas cleanup and methane synthesis. By combining syngas methanation, water-gas-shift, and CO2 sorption in a single reactor, single pass yield to methane of 99% was demonstrated at 10 bar and 330oC when using a 20 wt% Ni/MgAl2O4 catalyst and a molten-phase promoted MgO-based sorbent. Under model feed conditions both the sorbent and catalyst exhibited favorable stability after multiple test cycles. The cleanup for warm gas cleanup of inorganics was broken down into three major steps: chloride removal, sulfur removal, and the removal for a multitude of trace metal contaminants. Na2CO3 was found to optimally remove chlorides at an operating temperature of 450ºC. For sulfur removal two regenerable ZnO beds are used for bulk H2S removal at 450ºC (<5 ppm S) and a non-regenerable ZnO bed for H2S polishing at 300ºC (<40 ppb S). It was also found that sulfur from COS could be adsorbed (to levels below our detection limit of 40 ppb) in the presence of water that leads to no detectable slip of H2S. Finally, a sorbent material comprising of Cu and Ni was found to be effective in removing trace metal impurities such as AsH3 and PH3 when operating at 300ºC. Proof-of-concept of the integrated cleanup process was demonstrated with gasifier-generated syngas produced at the Western Research Institute using Wyoming Decker Coal. When operating with a ~1 SLPM feed, multiple inorganic contaminant removal sorbents and a tar-reforming bed was able to remove the vast majority of contaminants from the raw syngas. A tar-reforming catalyst was employed due to the production of tars generated from the gasifier used in this particular study. It is envisioned that in a real application a commercial scale gasifier operating at a higher temperature would produce lesser amount of tar. Continuous operation of a poison-sensitive copper-based WGS catalyst located downstream from the cleanup steps resulted in successful demonstration. ?

Development of Continuous Solvent Extraction Processes For Coal Derived Carbon Products  

SciTech Connect (OSTI)

In this reporting period, tonnage quantities of coal extract were produced but solid separation was not accomplished in a timely manner. It became clear that the originally selected filtration process would not be effective enough for a serious commercial process. Accordingly, centrifugation was investigated as a superior means for removing solids from the extract. Results show acceptable performance. Petrographic analysis of filtered solids was carried out by R and D Carbon Petrography under the auspices of Koppers and consultant Ken Krupinski. The general conclusion is that the material appears to be amenable to centrifugation. Filtered solids shows a substantial pitch component as well as some mesophase, resulting in increased viscosity. This is likely a contributing reason for the difficulty in filtering the material. Cost estimates were made for the hydotreatment and digestion reactors that would be needed for a 20,000 ton per year demonstration plants, with the aid of ChemTech Inc. The estimates show that the costs of scaling up the existing tank reactors are acceptable. However, a strong recommendation was made to consider pipe reactors, which are thought to be more cost effective and potentially higher performance in large scale systems. The alternate feedstocks for coke and carbon products were used to fabricate carbon electrodes as described in the last quarterly report. Gregory Hackett successfully defended his MS Thesis on the use of these electrodes in Direct Carbon Fuel Cell (DCFC), which is excerpted in Section 2.4 of this quarterly report.

TREATMENT OF METAL-LADEN HAZARDOUS WASTES WITH ADVANCED CLEAN COAL TECHNOLOGY BY-PRODUCTS  

SciTech Connect (OSTI)

Metal-laden wastes can be stabilized and solidified using advanced clean coal technology by-products (CCTBs)--fluid bed combustor ash and spray drier solids. These utility-generated treatment chemicals are available for purchase through brokers, and commercial applications of this process are being practiced by treaters of metal-laden hazardous waste. A complex of regulations governs this industry, and sensitivities to this complex has discouraged public documentation of treatment of metal-laden hazardous wastes with CCTBs. This report provides a comprehensive public documentation of laboratory studies that show the efficacy of the stabilization and solidification of metal-laden hazardous wastes--such as lead-contaminated soils and sandblast residues--through treatment with CCTBs. It then describes the extensive efforts that were made to obtain the permits allowing a commercial hazardous waste treater to utilize CCTBs as treatment chemicals and to install the equipment required to do so. It concludes with the effect of this lengthy process on the ability of the treatment company to realize the practical, physical outcome of this effort, leading to premature termination of the project.

Water effects of the use of western coal for electrical production  

SciTech Connect (OSTI)

Water may be a constraint on the expanded development of coal resources in the semi-arid western United States. Water allocation in the West has been determined by the appropriative rights doctrine which allows perpetual use of water sources by those who first claim it for beneficial purposes. This has had the effect of placing a dominative interest in water allocation in one economic sector: agriculture. New water sources are available to coal producers but political and economic problems must be overcome. Water is required by every phase of coal development. Mines use water for dust control and land reclamation. Coal slurry pipelines would use water as a transport medium. Steam electric power plants use water for cooling, cleaning, and in the boiler. Coal gasification plants would use water for cooling, cleaning, and as a material input. In addition to these direct uses of water by coal development, the people who build and operate the development demand water for domestic and recreational purposes. The quantity of water required for a given element of a coal development is site specific and dependent on many factors. The available literature cites a range of estimates of the amount of water required for each type of development. The width of this range seems related to the stage of development of the particular technology. Estimates of water requirements for various schemes to provide an average electrical load of 9 GWe to a load center 1000 miles from western mines are shown in Table 5.

Co-management of coal combustion by-products and low-volume wastes: A Southeastern Site  

SciTech Connect (OSTI)

The Electric Power Research Institute initiated this study to provide environmental data on the co-management of utility high volume and low volume residues. This report presents results from a field investigation at an ash pond located at a 400 MW, coal-fired power plant in the southeastern US. The pond receives wet-sluiced fly ash and bottom ash from the generating station as well as low volume wastes from coal preparation, demineralizer regeneration, and boiler cleaning. A detailed hydrogeochemical characterization of the primary ash disposal pond and surrounding groundwater system was performed. A total of 25 monitoring wells were installed to characterize groundwater flow directions, rates and chemistry. Ash and soil cores were also collected for hydrogeochemical characterization.

Simulation of CO2 Sequestration and Enhanced Coalbed Methane Production in Multiple Appalachian Basin Coal Seams  

SciTech Connect (OSTI)

A DOE-funded field injection of carbon dioxide is to be performed in an Appalachian Basin coal seam by CONSOL Energy and CNX Gas later this year. A preliminary analysis of the migration of CO2 within the Upper Freeport coal seam and the resulting ground movements has been performed on the basis of assumed material and geometric parameters. Preliminary results show that ground movements at the field site may be in a range that are measurable by tiltmeter technology.

U.S. Coal Supply and Demand: 2003 Review  

Gasoline and Diesel Fuel Update (EIA)

3 Review 3 Review 1 U.S. Coal Supply and Demand: 2003 Review by Fred Freme U.S. Energy Information Administration Overview U.S. coal production fell for the second year in a row in 2003, declining by 24.8 million short tons to end the year at 1,069.5 million short tons according to preliminary data from the Energy Information Administration (Table 1), down 2.3 percent from the 2002 level of 1,094.3 million short tons. (Note: All percentage change calculations are done at the short ton level.) Total U.S. coal consumption rose in 2003, with all coal-consuming sectors increasing or remaining stable for the year. Coal consumption in the electric power sector increased by 2.4 percent. However, there were only slight gains in consumption by the other sectors. U.S. coal exports rose in 2003 for the first time in

Stable isotope and water quality analysis of coal bed methane production waters and gases from the Bowen Basin, Australia  

Science Journals Connector (OSTI)

Coal bed methane (CBM) is a significant growing industry in Queensland's energy sector. It is, however, a relatively new industry with little local water quality data and stable isotope compositions of production waters and gases available in the public domain. This study aims to determine whether water quality and stable isotope data can be correlated with gas and groundwater production and flow pathways, and identify zones of recharge and water mixing. Stable isotope analysis and accessory water quality tests were conducted on CBM production gas and water samples collected from two CBM producing bituminous coal seams within a single field in the Bowen Basin. In the production field, the reservoir seams are gently folded with eastwardly dipping fold axes, and compartmentalised by an ENE normal fault on the flank of a broad central anticline that contains minor faults. For one seam, splitting and a change in coal quality parallels the fault and fold axes. Although virgin reservoir conditions were similar, differing production performance north and south of the main fault suggests it acts as a barrier to water and gas flow along strike. The stable isotope analysis on the production water showed that waters with more positive ?D and ?18O compositions were associated with areas of higher water production and shallower depths, whereas more negative ?D and ?18O compositions were associated with lower water production and high gas production. The gas isotope analysis showed that production gases had both biogenic and thermogenic origins and that secondary biogenic gas generated through CO2 reduction comprises a significant portion of the CBM produced from this field. More negative CH4 ?13C values characterize the zones of meteoric recharge in shallow, up-dip areas. Gas production data and CO2 ?13C values suggest that this may result from 13CH4 stripping by the recharge waters and/or increased biogenic activity in this area. Smaller CO2–CH4 carbon isotopic fractionation values characterized zones of meteoric recharge, whereas higher isotopic fractionation values characterized the high gas production domain.

Tasks 1 and 2 involve preparation of a Project Management Plan and establishment of a Participants Agreement/Proprietary Information Agreement for members of the Carbon Products Consortium (CPC). These tasks are now complete. Task 3 is to provide a series of samples of solvent extracted coal to the CPC participants and to incorporate their feedback and suggestions into subsequent samples. As of September 30, 1995, UCAR has received two rounds of samples; Koppers has received one round of samples; ALCOA and AMOCO have not yet specified the types of samples they wish to receive; FMI has received one round of samples and has requested a rather large, five kilogram, sample of coal extracts to do multiple impregnation on a large carbon fiber preform. There are extensive communications between the WVU research team and the five industrial partners. Task 4, cooperation with MITRE on their preparation of an economic analysis of the solvent extraction, is complete. Task 5, Technology Transfer, is an on going endeavor with research team meetings, general CPC meetings, presentations of conference papers, and submission of required reports. The CPC is finally functioning as it has been envisioned, i.e., with the WVU solvent extracted coal materials being evaluated by several companies as precursor for their individual product lines. The companies are comparing the WVU materials with commercially available pitches and cokes.

Modernization of Ohio's coal reserves, Phase 1  

SciTech Connect (OSTI)

The objectives of this project were to determine state-level totals of the estimated economic resource, minable reserve base, and recoverable coal in Ohio, allocated to specified ranges of sulfur and heat content. In addition, resources and reserves were to be categorized by mining methods (surface and underground). Land use and environmental restrictions, needed to determine remaining minable reserves, were to be delineated and percentages of restricted coal calculated. In context of a Phase 1, one-year project, the objectives of this project were to update Ohio's coal reserves and resources for as many counties as time allowed, and to deplete production tonnages to January 1, 1991, on the remaining coal-producing counties. For the depleted counties, only estimated economic resources were required or possible with the data available. 24 refs., 9 figs., 3 tabs.

Design manual for management of solid by-products from advanced coal technologies  

SciTech Connect (OSTI)

Developing coal conversion technologies face major obstacles in byproduct management. This project has developed several management strategies based on field trials of small-scale landfills in an earlier phase of the project, as well as on published/unpublished sources detailing regulatory issues, current industry practice, and reuse opportunities. Field testing, which forms the basis for several of the disposal alternatives presented in this design manual, was limited to byproducts from Ca-based dry SO{sub 2} control technologies, circulating fluidized bed combustion ash, and bubbling bed fluidized bed combustion ash. Data on byproducts from other advanced coal technologies and on reuse opportunities are drawn from other sources (citations following Chapter 3). Field results from the 5 test cases examined under this project, together with results from other ongoing research, provide a basis for predictive modeling of long-term performance of some advanced coal byproducts on exposure to ambient environment. This manual is intended to provide a reference database and development plan for designing, permitting, and operating facilities where advanced coal technology byproducts are managed.

Investigations into coal coprocessing and coal liquefaction  

SciTech Connect (OSTI)

The conversion of coal to liquid suitable as feedstock to a petroleum refinery is dependent upon several process variables. These variables include temperature, pressure, coal rank, catalyst type, nature of the feed to the reactor, type of process, etc. Western Research Institute (WRI) has initiated a research program in the area of coal liquefaction to address the impact of some of these variables upon the yield and quality of the coal-derived liquid. The principal goal of this research is to improve the efficiency of the coal liquefaction process. Two different approaches are currently being investigated. These include the coprocessing of a heavy liquid, such as crude oil, and coal using a dispersed catalyst and the direct liquefaction of coal using a supported catalyst. Another important consideration in coal liquefaction is the utilization of hydrogen, including both externally- and internally-supplied hydrogen. Because the incorporation of externally-supplied hydrogen during conversion of this very aromatic fossil fuel to, for example, transportation fuels is very expensive, improved utilization of internally-supplied hydrogen can lead to reducing processing costs. The objectives of this investigation, which is Task 3.3.4, Coal Coprocessing, of the 1991--1992 Annual Research Plan, are: (1) to evaluate coal/oil pretreatment conditions that are expected to improve the liquid yield through more efficient dispersion of an oil-soluble, iron-based catalyst, (2) to characterize the coke deposits on novel, supported catalysts after coal liquefaction experiments and to correlate the carbon skeletal structure parameters of the coke deposit with catalyst performance as measured by coal liquefaction product yield, and (3) to determine the modes of hydrogen utilization during coal liquefaction and coprocessing. Experimental results are discussed in this report.

The economical production of alcohol fuels from coal-derived synthesis gas. Sixth quarterly technical progress report, January 1, 1993--March 31, 1993  

SciTech Connect (OSTI)

Preliminary economic investigations have focused on cost reduction measures in the production of syngas from coal. A spread sheet model has been developed which can determine the cost of syngas production based upon the cost of equipment and raw materials and the market value of energy and by-products. In comparison to natural gas derived syngas, coal derived syngas is much more expensive, suggesting a questionable economic status of coal derived alcohol fuels. While it is possible that use of less expensive coal or significant integration of alcohol production and electricity production may reduce the cost of coal derived syngas, it is unlikely to be less costly to produce than syngas from natural gas. Fuels evaluation is being conducted in three parts. First, standard ASTM tests are being used to analyze the blend characteristics of higher alcohols. Second, the performance characteristics of higher alcohols are being evaluated in a single-cylinder research engine. Third, the emissions characteristics of higher alcohols are being investigated. The equipment is still under construction and the measurement techniques are still being developed. Of particular interest is n-butanol, since the MoS{sub 2} catalyst produces only linear higher alcohols. There is almost no information on the combustion and emission characteristics of n-butanol, hence the importance of gathering this information in this research.

coal.gif (4423 bytes) coal.gif (4423 bytes) The NEMS Coal Market Module (CMM) provides forecasts of U.S. coal production, consumption, exports, distribution, and prices. The CMM comprises three functional areas: coal production, coal distribution, and coal exports. A detailed description of the CMM is provided in the EIA publication, Model Documentation: Coal Market Module of the National Energy Modeling System, DOE/EIA-MO60. Key Assumptions Coal Production The coal production submodule of the CMM generates a different set of supply curves for the CMM for each year of the forecast. Separate supply curves are developed for each of 11 supply regions, and 12 coal types (unique combinations of thermal grade, sulfur content, and mine type). The modeling approach used to construct regional coal supply curves addresses the relationship between the minemouth price of coal and corresponding levels of coal production, labor productivity, and the cost of factor inputs (mining equipment, mine labor, and fuel requirements).

The Wyodak-Anderson coal assessment, Powder River Basin, Wyoming and Montana -- An ArcView project  

SciTech Connect (OSTI)

In 1997, more than 305 million short tons of clean and compliant coal were produced from the Wyodak-Anderson and associated coal beds and zones of the Paleocene Fort Union Formation in the Powder River Basin, Wyoming and Montana. To date, all coal produced from the Wyodak-Anderson, which averages 0.47 percent sulfur and 6.44 percent ash, has met regulatory compliance standards. Twenty-eight percent of the total US coal production in 1997 was from the Wyodak-Anderson coal. Based on the current consumption rates and forecast by the Energy Information Administration (1996), the Wyodak-Anderson coal is projected to produce 413 million short tons by the year 2016. In addition, this coal deposit as well as other Fort Union coals have recently been targeted for exploration and development of methane gas. New US Geological Survey (USGS) digital products could provide valuable assistance in future mining and gas development in the Powder River Basin. An interactive format, with querying tools, using ArcView software will display the digital products of the resource assessment of Wyodak-Anderson coal, a part of the USGS National Coal Resource Assessment of the Powder River Basin. This ArcView project includes coverages of the data point distribution; land use; surface and subsurface ownerships; coal geology, stratigraphy, quality and geochemistry; and preliminary coal resource calculations. These coverages are displayed as map views, cross sections, tables, and charts.

Coal liquefaction quenching process  

DOE Patents [OSTI]

There is described an improved coal liquefaction quenching process which prevents the formation of coke with a minimum reduction of thermal efficiency of the coal liquefaction process. In the process, the rapid cooling of the liquid/solid products of the coal liquefaction reaction is performed without the cooling of the associated vapor stream to thereby prevent formation of coke and the occurrence of retrograde reactions. The rapid cooling is achieved by recycling a subcooled portion of the liquid/solid mixture to the lower section of a phase separator that separates the vapor from the liquid/solid products leaving the coal reactor.

Blackout: coal, climate and the last energy crisis  

SciTech Connect (OSTI)

Coal fuels more than 30 per cent of UK electricity production, and about 50 per cent in the US, providing a significant portion of total energy output. China and India's recent ferocious economic growth has been based almost entirely on coal-generated electricity. Coal currently looks like a solution to many of our fast-growing energy problems. However, while coal advocates are urging us full steam ahead, the increasing reliance on this dirtiest of all fossil fuels has crucial implications for energy policy, pollution levels, the global climate, world economy and geopolitics. Drawbacks to a coal-based energy strategy include: Scarcity - new studies suggest that the peak of world coal production may actually be less than two decades away; Cost - the quality of produced coal is declining, while the expense of transportation is rising, leading to spiralling costs and increasing shortages; and, Climate impacts - our ability to deal with the historic challenge of climate change may hinge on reducing coal consumption in future years.

Science Journals Connector (OSTI)

The paper describes the development of a computer-based total productive maintenance (TPM) model to improve electrical motors readiness and uptime while reducing capital overhead. The TPM model includes the consideration of reactive, periodic, and predictive practices. The input data is processed and the generated report details a set of periodic recommendations providing guidelines on recommended actions and their frequency. The details about test results indicating the current condition of the motor as well estimated reactive, periodic, and predictive maintenance cost details are presented. Based on the historic data stored in its database, the model can predict potential problems prior to failure as well as prescribe periodic maintenance actions to maximise motor life. The TPM model will be a useful tool to predict the degradation in motor life due to deterioration in insulation, bearing, rotor bar and stator windings of the motor.

Comanagement of coal combustion by-products and low-volume wastes: A midwestern site  

SciTech Connect (OSTI)

This report presents results from a field evaluation of the environmental effects of co-management of high-volume coal combustion residues with low-volume non-combustion wastes at a utility power plant. At the C-site, located in the midwestern United States, fly ash and bottom ash from the combustion of bituminous Indiana coal are co-managed with non-combustion wastes including pyrite rejects from coal cleaning, demineralizer regenerant, runoff water from the plant grounds, and boiler cleaning wastes. These wastes are disposed of in an unlined ash pond on site. The pond discharges primarily to the surrounding shallow groundwater with a limited surface discharge to a nearby river. Hydrological monitoring took place over a nine-month period in 1989 and 1990. Groundwater and soil samples were collected on three occasions during this time. Samples were analyzed to determine the groundwater chemistry, and soil and waste chemistry and geochemistry. Downgradient wells showed an increased concentration of several ash-derived species including boron, calcium, fluoride, potassium, sodium, strontium, and sulfate. The median sulfate concentration in downgradient wells was 350 mg/L, which exceeds the secondary drinking water limit. Statistical comparison of the composition of background groundwater with water from wells downgradient of the ash ponds was limited by a single set of background water samples. Soils beneath the pond appear to have limited attenuative capacity for ash-derived trace metals, and groundwater velocities are high; however, trace metal concentrations in downgradient wells are similar to background levels. No impact uniquely attributable to the co-management of low-volume wastes was detectable at this site.

Further investigation of the impact of the co-combustion of tire-derived fuel and petroleum coke on the petrology and chemistry of coal combustion products  

SciTech Connect (OSTI)

A Kentucky cyclone-fired unit burns coal and tire-derived fuel, sometimes in combination with petroleum coke. A parallel pulverized combustion (pc) unit at the same plant burns the same coal, without the added fuels. The petrology, chemistry, and sulfur isotope distribution in the fuel and resulting combustion products was investigated for several configurations of the fuel blend. Zinc and Cd in the combustion products are primarily contributed from the tire-derived fuel, the V and Ni are primarily from the petroleum coke, and the As and Hg are probably largely from the coal. The sulfur isotope distribution in the cyclone unit is complicated due to the varying fuel sources. The electrostatic precipitator (ESP) array in the pc unit shows a subtle trend towards heavier S isotopic ratios in the cooler end of the ESP.

Social dimensions of energy supply alternatives in steelmaking: comparison of biomass and coal production scenarios in Australia  

Science Journals Connector (OSTI)

Abstract Global climatic change is driving research and development in low emissions technologies. One such technology is the use of charcoal from biomass in steelmaking. This paper adapts social life cycle assessment methodologies to analyse the social dimensions of energy supply alternatives in steelmaking using regionalised production scenarios in Australia. Three energy supply alternatives are investigated: charcoal produced from Radiata pine plantation forestry; charcoal produced from Mallee eucalypt revegetation on agricultural land; and metallurgical coal. Impact indicators analysed include land-use, employment, workplace health & safety and a qualitative analysis of identified stakeholder issues. The research finds that biomass alternatives are significant generators of direct employment at the regional level; have concomitantly higher rates of workplace injuries and represent a significant change in land-use. Charcoal produced from Mallee biomass planted as a conservation measure on farmland, however, has the benefit of representing a shared land-use that provides an additional farm revenue stream and assists dryland salinity management. The paper finds that full substitution of coal by pine or Mallee charcoal does not provide a unique solution for optimising the social performance of the energy supply alternatives across all indicators.

Heat treatment of medium-temperature Sasol–Lurgi gasifier coal-tar pitch for polymerizing to higher value products  

Science Journals Connector (OSTI)

Two coal-derived pitch samples, one a medium temperature pitch from a Sasol–Lurgi gasifier and the other from a high temperature coking process, have been heat treated to induce polymerization, both separately and as a mixture of pitches (co-pyrolysis). The initial pitch samples and the heat-treated samples have been examined by size exclusion chromatography (SEC) in 1-methyl-2-pyrrolidinone (NMP), by UV-fluorescence spectroscopy (UV-F), by solid state 13C NMR; elemental analyses of the initial pitch samples have been carried out. The Sasol–Lurgi pitch showed larger apparent sizes, more alkyl and carbonyl functions, and smaller polycyclic aromatic hydrocarbon (PAH) groups than the high temperature pitch. Co-pyrolysis of the two pitches indicated that polymerized product from the Sasol–Lurgi pitch can be used as an extender for high-temperature binder pitch.

Sulfur and ash in Paleocene Wyodak-Anderson coal in the Powder River Basin, Wyoming and Montana: A fuel source beyond 2000  

SciTech Connect (OSTI)

When coal-fired power plants are required by the Environmental Protection Agency (EPA) to meet more stringent sulfur emission standards (0.6 pound per million Btu) after the year 2000, most of the clean and compliant coals will come from the Powder River Basin in Wyoming and Montana. In 1996 more than 300 million short toms of these clean and compliant coals were produced from the Paleocene Fort Union Formation in the northern Rocky Mountains and Great Plans region. This is more than 30% of the total US coal production of 1.03 billion short tons in 1996. Future demand for clean and compliant coals can probably be met through production of more F or Union coals in the region. It is projected by the Energy Information Agency (1996) that most of the low-sulfur and low-ash coals in the northern Rocky Mountains and Great Plains region will be produced from the Wyodak-Anderson coal bed/zone of the Paleocene Fort Union Formation in the Powder River Basin. To date, coal produced from the Wyodak-Anderson coal bed/zone, containing 0.5% sulfur, 1.2 lb SO{sub 2} per million btu, and 6% ash (mean values on an as-received basis) meet current EPA regulatory compliance. This coal bed/zone alone produced 262 million short toms of >26% of the total US coal production in 1996. Based on the current consumption rates of coal and a forecast by the EIA (1996), the Wyodak-Anderson coals are projected to produce an additional 153 million short tons a year by the year 2016. At this rate of production, high quality Wyodak-Anderson coals may be adequate to fill future energy needs.

Determination of total mercury in seafood and other protein-rich products  

SciTech Connect (OSTI)

A previously developed wet-digestion method for the determination of total mercury in plants by cold vapor atomic absorption spectroscopy (CVAAS) was extended to the analysis of seafood and other products rich in proteins. Oxidation of matrixes is accomplished by K{sub 2}Cr{sub 2}O{sub 7} in the presence of diluted H{sub 2}SO{sub 4}; a simple air condenser is used to reflux vapors released from the boiling mixture. The original procedure (A) and 2 modifications (B and C), which differ with respect to the mode of acidification and/or digestion time and the types of condensers used, were compared for precision and accuracy by means of National Institute of Standards and Technology Research Material 50 Albacore Tuna and proved to be reliable (Hg present, 0.95{plus_minus}0.1 {mu}g/g; Hg found, 0.97 {plus_minus} 0.029 {mu}g/g [A], 0.98 {plus_minus} 0.018 {mu}g/g [B], and 0.94 {plus_minus} 0.025 {mu}g/g [C]). The modified procedures were tested further in Hg recovery experiments on a variety of biological matrixes with different spiking substances and again showed good analytical characteristics (overall average recoveries = 98 {plus_minus} 5.1% for seafood and 100 {plus_minus} 3.6 for protein-rich baby foods). 22 refs., 1 fig., 5 tabs.

Coal-oil slurry preparation  

DOE Patents [OSTI]

A pumpable slurry of pulverized coal in a coal-derived hydrocarbon oil carrier which slurry is useful as a low-ash, low-sulfur clean fuel, is produced from a high sulfur-containing coal. The initial pulverized coal is separated by gravity differentiation into (1) a high density refuse fraction containing the major portion of non-coal mineral products and sulfur, (2) a lowest density fraction of low sulfur content and (3) a middlings fraction of intermediate sulfur and ash content. The refuse fraction (1) is gasified by partial combustion producing a crude gas product from which a hydrogen stream is separated for use in hydrogenative liquefaction of the middlings fraction (3). The lowest density fraction (2) is mixed with the liquefied coal product to provide the desired fuel slurry. Preferably there is also separately recovered from the coal liquefaction LPG and pipeline gas.

Coal - prices tumble as the glut continues  

SciTech Connect (OSTI)

The oil price collapse was the major event affecting coal markets around the world in 1986. The 8% expansion in international coal trade in 1985 was halted, and prices fell considerably. World coking coal trade declined and import and export prices fell due to a decrease in steel production and the use of oil, rather than pulverized coal, in blast furnaces. However steam coal trade increased by about 5 million mt because of various institutional constraints to utilities switching from coal burning to oil burning. The article covers coal trade and production in the following countries: Australia; Canada; China; Colombia; Western Europe; Japan; Poland; South Africa; and the USSR.

SciTech Connect (OSTI)

The Carbon Products Consortium (CPC) is a university, industry, national laboratory cooperative research, development and commercialization partnership focused on the use of coal-derived precursors for a wide range of carbon products. The CPC program has evolved over five years through the combined efforts of academic, congressional, industrial, and government agency participation and support. The PETC funded WVU portion of the CPC involves both administration and research. During the preceding quarter, the Project Management Plan specified in Task 1 of the Workplan has been initiated and a draft will be submitted to the DOE COR. A CPC Participants Agreement has been approved and signed by the university and industrial participants. The WVU carbon products group has added three additional technicians to help initiate the project. Several new reactor systems have been obtained for the solvent extraction lab. Due to WVU`s experience and background in solvent extraction of coal, the WVU portion of the project will be in operation very soon. Several small samples (one ounce or less) of coal extracts will be provided to UCAR for initial screening.

Comparative analysis of the production costs and life-cycle GHG emissions of FT liquid fuels from coal and natural gas  

SciTech Connect (OSTI)

Liquid transportation fuels derived from coal and natural gas could help the United States reduce its dependence on petroleum. The fuels could be produced domestically or imported from fossil fuel-rich countries. The goal of this paper is to determine the life-cycle GHG emissions of coal- and natural gas-based Fischer-Tropsch (FT) liquids, as well as to compare production costs. The results show that the use of coal- or natural gas-based FT liquids will likely lead to significant increases in greenhouse gas (GHG) emissions compared to petroleum-based fuels. In a best-case scenario, coal- or natural gas-based FT-liquids have emissions only comparable to petroleum-based fuels. In addition, the economic advantages of gas-to-liquid (GTL) fuels are not obvious: there is a narrow range of petroleum and natural gas prices at which GTL fuels would be competitive with petroleum-based fuels. CTL fuels are generally cheaper than petroleum-based fuels. However, recent reports suggest there is uncertainty about the availability of economically viable coal resources in the United States. If the U.S. has a goal of increasing its energy security, and at the same time significantly reducing its GHG emissions, neither CTL nor GTL consumption seem a reasonable path to follow. 28 refs., 2 figs., 4 tabs.

Forward and reverse combustion gasification of coal with production of high-quality syngas in a simulated pilot system for in situ gasification  

Science Journals Connector (OSTI)

Abstract This research focused on the feasibility and stability of applying the forward and reverse combustion approach to the in situ gasification of lignite and bituminous coal with oxygen or oxygen–steam mixtures as gasification agents, especially reverse combustion gasification. A high-quality syngas (H2 and CO) could be obtained using the reverse combustion gasification technique combined with forward combustion gasification in a pilot system for in situ gasification. The gasification time was extended more than 25% using the reverse combustion approach. The controlling conditions for reverse combustion gasification were obtained by comparing and analyzing experimental data. The results show the relationship between the inject gas flow within certain limits and velocity of the gasification flame was linear during reverse combustion. The underground conditions of the coal seam and strata were simulated in a pilot-scale underground gasifier during experiments. The combustion gasification of coal was carried out experimentally for over 5 days. The average effective content (H2 and CO) of syngas was in the range of 60–70%, meeting the requirement of synthesis gas. The optimal ranges of gasifying lignite and bituminous coal were found to be 1.5–2.0 and 1.3–1.75, respectively. The product gas flow was proportional to oxygen blast. These are expected to provide useful guidance on practical underground coal gasification operations and to give experimental evidence in support of theory.

Waste biomass from production process co-firing with coal in a steam boiler to reduce fossil fuel consumption: A case study  

Science Journals Connector (OSTI)

Abstract Waste biomass is always generated during the production process in industries. The ordinary way to get rid of the waste biomass is to send them to landfill or burn it in the open field. The waste may potentially be used for co-firing with coal to save fossil fuel consumption and also reduce net carbon emissions. In this case study, the bio-waste from a Nicotiana Tabacum (NT) pre-treatment plant is used as the biomass to co-fire with coal. The samples of NT wastes were analysed. It was found that the wastes were of the relatively high energy content which were suitable for co-firing with coal. To investigate the potential and benefits for adding NT wastes to a Fluidised Bed Combustion (FBC) boiler in the plant, detailed modelling and simulation are carried out using the European Coal Liquefaction Process Simulation and Evaluation (ECLIPSE) process simulation package. The feedstock blending ratios of NT waste to coal studied in this work are varied from 0% to 30%. The results show that the addition of NT wastes may decrease the emissions of CO2 and \\{SOx\\} without reducing the boiler performance.

Parametric analysis of total costs and energy efficiency of 2G enzymatic ethanol production  

Science Journals Connector (OSTI)

Abstract This paper presents an analysis of total costs (TPC) and energy efficiency of enzymatic ethanol production. The analysis is parametrized with respect to plant capacity and polysaccharides content (pc) of lignocellulosic feedstock. The feedstock is based on wheat straw whose price is proportional to its pc ranging from new straw with high pc and high cost to agro-wastes with limited pc but lower cost. The plant flowsheet was built using a conventional biochemical platform with co-saccharification and fermentation (SHF) technologies. A parametric analysis of TPC as a function of plant capacity (100–2100 ton DB/day) and pc (i.e. feedstock price) (80% (75 USD/ton DB)–35% (6 USD/ton DB)) was performed with Net Present Value (NPV) techniques. Current data from Mexican economics and the agro-industrial sector were used as an illustrative case. A quasi-linear section of the TCP surface was identified delimited by (300–1100 ton DB/day) and (80–55% pc) with increments no larger than 21% of the minimum TPC obtained (0.99 USD/l etOH for 2100 ton DB/day and 80% pc). Major cost contributions are detailed and quantified for boundary cases of this surface. Energy consumption and production were also calculated for all the plant capacity and feedstock pc cases, taking into consideration the Maximum Energy Recovery (MER) obtained from a Pinch analysis. The end-use energy index eer was less than 0.82 for all cases, thus stressing the need to use process equipment with lower energy requirements. TPC are compared against previously published results for SHF technology between 500 and 2100 ton DB/day plant capacities. These values were updated and normalized with respect to feedstock and enzyme costs employed in this work. Differences among TPC and recently published normalized results are within a ±5% range, thus confirming the dependence of TPC from feedstock and enzyme prices, regardless of flowsheet technology and economic conditions.
