Testing for market integration crude oil, coal, and natural gas  

SciTech Connect

Prompted by the contemporaneous spike in coal, oil, and natural gas prices, this paper evaluates the degree of market integration both within and between crude oil, coal, and natural gas markets. Our approach yields parameters that can be readily tested against a priori conjectures. Using daily price data for five very different crude oils, we conclude that the world oil market is a single, highly integrated economic market. On the other hand, coal prices at five trading locations across the United States are cointegrated, but the degree of market integration is much weaker, particularly between Western and Eastern coals. Finally, we show that crude oil, coal, and natural gas markets are only very weakly integrated. Our results indicate that there is not a primary energy market. Despite current price peaks, it is not useful to think of a primary energy market, except in a very long run context.

Marketing coal ash, slag, and sludge  

Science Conference Proceedings (OSTI)

The increase in coal-fired power plants and tighter environmental problems have put utilities in the position of marketing coal ash, slag, and sludge by turning waste products into a resource. Many utilities are looking beyond road and structural fill uses in their marketing efforts. Slag can be made into sandblasting grit, aggregate, and roofing granules, or used for soil stabilization or the chemical fixation of municipal wastes. Composition and collection variations discourage many utilities from marketing their by-products, while availability can be a problem for customers if the power plant should shut down. Other problems include storage and transportation, competition, and institutional barriers. Documentation of the fly ash, bottom ash, boiler slag, and scrubber waste markets by the Electric Power Research Institute considers these factors and develops a marketing method to help utilities evaluate and promote their product.

Market integration in the international coal industry: A cointegration approach  

SciTech Connect

The purpose of this paper is to test the hypothesis of the existence of a single economic market for the international coal industry, separated for coking and steam coal, and to investigate market integration over time. This has been conducted by applying cointegration and error-correction models on quarterly price series data in Europe and Japan over the time period 1980-2000. Both the coking and the steam coal markets show evidence of global market integration, as demonstrated by the stable long-run cointegrating relationship between the respective price series in different world regions. This supports the hypothesis of a globally integrated market. However, when analyzing market integration over time it is not possible to confirm cointegration in the 1990s for steam coal. Thus, compared to the coking coal market, the steam coal market looks somewhat less global in scope.

Coal bed methane global market potential  

Science Conference Proceedings (OSTI)

Worldwide increases in energy prices, as well as the increased potential for project financing derived from emissions credits, have renewed focus on coal bed methane (CBM) and coal mine methane (CMM) projects in coal-producing countries around the world. Globally, CBM utilization projects (in the operational, development, or planning stages) capture and utilize methane from gassy underground coal mines in at least 13 countries. The total methane emission reductions that could be achieved by these projects are approximately 135 billion cubic feet per year (equal to 14.8 million tons of carbon equivalent per year). This global activity level reflects a growing awareness of the technological practicality and the economic attractiveness of coal mine methane recovery and use. This report outlines the potential of the global CBM market. Contents: An overview of CBM; Challenges and issues; Technologies to generate power from CAM; Global CBM/CMM utilization; Country highlights; Ranking of countries with the largest CMM development potential (Australia, Canada, China, Germany, Mexico, Poland, Russia, Ukraine, United Kingdom, USA, Bulgaria, Czech Republic, France, India, Japan, Kazakhstan, South Africa); Planning CBM/CMM projects; Pre-feasibility and feasibility studies; Demonstration projects; Development plan and application process; Equity and debt; Carbon financing; Government sponsors; Private sponsors; Project risk reduction support; Examples of integrated project financing; Glossary.

Revised market guide for coal exports from the United States  

SciTech Connect

The world market for steam coal is assessed. In recent years, much has changed in the world coal markets and in the expected opportunities for coal exports from the US. As an example, the overseas steam coal exports climbed from about 2 million tons in 1979 to about 35 million tons in 1981. Since then the overseas steam coal exports have fallen to 27 million tons in 1982 and to 17 million tons in 1983. In addition, metallurgical coal exports to overseas customers dropped from 60 million tons in 1982 to 43 million tons in 1983. This market guide is divided into four sections: Section one contains a review of the most frequently asked questions by individuals interested in the overseas coal markets and the role of US producers in this market; Section two contains an overview of the market for US steam and metallurgical coal exports, including forecasts of import demands, potential US market share, and the factors affecting this market share; Section three contains an outline of the current structure of the steam coal export trade in the US and the potential developments that will influence its future, and Section four contains a review of the important data on the nature of the energy-using industries, utilities and power plants, cement plants, coal quality requirements, and ports of the major steam and metallurgical coal importing countries. 14 figures, 45 tables.

Potential for producing and marketing gasoline substitutes from western coal  

SciTech Connect

Through June, 1978, one major emphasis of the program is a regional coal assessment for input to the ERDA National Coal Assessment (NCA). The NCA will utilize information on regional energy options to (1) generate development scenarios and to (2) evaluate regional impacts associated with these scenarios. One problem that the NCA must face is determining the likelihood of a particular development occurring within the region. Before embarking on a large-scale program to assess the socio-economic, environmental, and health effects of placing several coal liquefaction plants in the western United States, it was essential to have some indication of ''if'' and ''when'' state-of-the-art and future technologies might be utilized. A multisector model with regional detail would be required to thoroughly assess the likelihood of commercial-scale liquefaction occurring in Montana and Wyoming under market conditions. However, significant information can be obtained from a constrained partial analysis, which was the procedure for this study. Some fundamental terminology used in this analysis is reviewed in Section 2 of this report. Future demand and potential supply of gasoline from domestic crude oil are treated in Sections 3 and 4. The costs of supplying synthetic gasoline and methanol from western coal as well as the qualitative aspects of these fuels are examined in Section 5. In Section 6 the supply and demand functions are solved simultaneously under various import schemes to trace out a family of gasoline-market equilibrium price curves over time. Three scenarios are then analyzed by comparing the costs of supplying synthetic fuels with the market equilibrium prices for gasoline. Market potential for the synthetic fuels is estimated for a wide range of coal prices. Section 7 includes a summary, concluding comments, and research recommendations. (MCW)

Analysis of the market and product costs for coal-derived high Btu gas  

Science Conference Proceedings (OSTI)

DOE analyzed the market potential and economics of coal-derived high-Btu gas using supply and demand projections that reflect the effects of natural gas deregulation, recent large oil-price rises, and new or pending legislation designed to reduce oil imports. The results indicate that an increasingly large market for supplemental gas should open up by 1990 and that SNG from advanced technology will probably be as cheap as gas imports over a wide range of assumptions. Although several studies suggest that a considerable market for intermediate-Btu gas will also exist, the potential supplemental gas demand is large enough to support both intermediate - and high-Btu gas from coal. Advanced SNG-production technology will be particularly important for processing the US's abundant, moderately to highly caking Eastern coals, which current technology cannot handle economically.

coal market module (CMM) represents the mining, transportation, and pricing of coal, subject to end-use demand. Coal supplies are differentiated by heat and sulfur content. CMM also determines the minimum cost pattern of coal supply to meet exogenously defined U.S. coal export demands as a part of the world coal market. Coal supply is projected on a cost-minimizing basis, constrained by existing contracts. Twelve different coal types are differentiated with respect to thermal grade, sulfur content, and underground or surface mining. The domestic production and distribution of coal is forecast for 13 demand regions and 11 supply regions (Figures 19 and 20). coal market module (CMM) represents the mining, transportation, and pricing of coal, subject to end-use demand.

INTRODUCTION As deregulation unfolds and privatization of the utility market takes shape, priorities for power plant economics have shifted toward those of a "bottom-line" business and away from a regulated industry. Competition in utility generation and the exposure risks of large capital investments have led to a preference to minimize capital costs and fixed and variable operation and maintenance costs. With global competition from independent power producers (IPPs), non- utility generators, and utilities, the present trend of investments is with conventional pulverized

Regional Supply Outlook for Market Driver Coals: A New Set of Fundamentals?  

Science Conference Proceedings (OSTI)

Coal prices have peaked twice since 2000 and have yet to return to pre-2000 levels. In the wake of this volatility, this report examines how coal supply fundamentals are changing for key "market-driver" coals and how these changes impact future markets for coal. Many believe the power industry will be able to use a broader range of cheaper, more abundant coals once tighter environmental requirements force additional technology controls around the country. Contrary to this belief, this report provides evi...

Clean Coal Technology: Region 4 Market Description, South Atlantic. Summary  

Science Conference Proceedings (OSTI)

The Region 4 Market Description Summary provides information that can be used in developing an understanding of the potential markets for clean coal technologies (CCTs) in the South Atlantic Region. This region (which geographically is Federal Region 4) consists of the following eight states: Alabama, Florida, Georgia, Kentucky, Mississippi, North Carolina, South Carolina, and Tennessee. In order to understand the potential market. A description is provided of the region`s energy use, power generation capacity, and potential growth. Highlights of state government activities that could have a bearing on commercial deployment of CCTs are also presented. The potential markets characterized in this summary center on electric power generation by investor-owned, cooperative, and municipal electric utilities and involve planned new capacity additions and actions taken by utilities to comply with Phases I and II of the Clean Air Act Amendments (CAAA) of 1990. Regulations, policies, utility business strategies, and organizational changes that could impact the role of CCTs as a utility option are identified and discussed. The information used to develop the Region 4 Market Description is based mainly on an extensive review of plans and annual reports of 29 investor-owned, cooperative, and municipal coal-using electric utilities and public information on strategies and actions for complying with the CAAA of 1990.

Marketing coal ash, slag, and sludge  

SciTech Connect

Investigates the selling of by-products of coal-fired power generation--fly ash, bottom ash, boiler slag, and scrubber sludge--by utilities for use in highways, parking lots, cement, roofing, bricks, and blocks. Points out that the EPA has drafted tough new regulations for solid-waste storage, transportation, and disposal that may soon cost power plants $25-$40 a ton to dispose of wastes. Reports that the EPRI is studying high-volume by-product applications that have low technology requirements (e.g. fly ash for use in highways, parking lots, and utility construction) and medium-volume, medium-technology applications (e.g. by-products used for cement manufacture, asphalt, blocks, bricks, roofing granules, and wallboards). Reveals that EPRI plans to eventually identify a representative set of perhaps half a dozen basic fly ashes, characterize them, do proportion studies of existing concrete mixes (including those with fly ash in them), and then develop guidelines for fly ash proportions in concrete.

Markets for small-scale, advanced coal-combustion technologies  

SciTech Connect

This report examines the potential of using US-developed advanced coal technologies (ACTs) for small combustors in foreign markets; in particular, the market potentials of the member countries of the Organization of Economic Co-operation and Development (OECD) were determined. First, the United States and those OECD countries with very low energy demands were eliminated. The remaining 15 countries were characterized on the basis of eight factors that would influence their decision to use US ACTs: energy plan and situation, dependence on oil and gas imports, experience with coal, residential/commercial energy demand, industrial energy demand, trade relationship with the United States, level of domestic competition with US ACT manufacturers, and environmental pressure to use advanced technology. Each country was rated high, medium-high, low-medium, or low on each factor, based on statistical and other data. The ratings were then used to group the countries in terms of their relative market potential (good, good but with impediments, or limited). The best potential markets appear to be Spain, Italy, turkey, Greece, and Canada. 25 refs., 1 fig., 37 tabs.

Market penetration potential of new clean coal technologies  

SciTech Connect

The diverse nature of the electric utility sector, both in terms of supply and demand, will allow numerous new coal-burning technologies to find economic niches within the marketplace. The focus of this paper is on the potential market penetration rate for one clean coal technology, Integrated Gasifier Combined Cycles (IGCC), from 1995 to 2024. The market penetration of IGCC was examined in two power pools that are distinctly different in terms of electric supply and demand. These pools consist of groups of companies that aggregate their resources for dispatching or trading electricity to achieve operating economies through energy exchanges. The first pool is located in the Midwest and is part of the North American Electric Reliability Council's (NERC) East Central Area Reliability Coordination Agreement (ECAR) region. The second pool is the Florida subregion of NERC's Southeastern Electric Reliability Council (SERC) region. Emphasis is placed on how both the current technology configuration of the power pool and how future demand profiles influence the penetration rate of a new technology. The effects of fuel prices on technology penetration are also examined. The argonne Utility Simulation (ARGUS) model is used to estimate IGCC market penetration under various economic assumptions. 20 refs., 8 figs.

Analysis of industrial markets for low and medium Btu coal gasification. [Forecasting  

SciTech Connect

Low- and medium-Btu gases (LBG and MBG) can be produced from coal with a variety of 13 existing and 25 emerging processes. Historical experience and previous studies indicate a large potential market for LBG and MBG coal gasification in the manufacturing industries for fuel and feedstocks. However, present use in the US is limited, and industry has not been making substantial moves to invest in the technology. Near-term (1979-1985) market activity for LBG and MBG is highly uncertain and is complicated by a myriad of pressures on industry for energy-related investments. To assist in planning its program to accelerate the commercialization of LBG and MBG, the Department of Energy (DOE) contracted with Booz, Allen and Hamilton to characterize and forecast the 1985 industrial market for LBG and MBG coal gasification. The study draws five major conclusions: (1) There is a large technically feasible market potential in industry for commercially available equipment - exceeding 3 quadrillion Btu per year. (2) Early adopters will be principally steel, chemical, and brick companies in described areas. (3) With no additional Federal initiatives, industry commitments to LBG and MBG will increase only moderately. (4) The major barriers to further market penetration are lack of economic advantage, absence of significant operating experience in the US, uncertainty on government environmental policy, and limited credible engineering data for retrofitting industrial plants. (5) Within the context of generally accepted energy supply and price forecasts, selected government action can be a principal factor in accelerating market penetration. Each major conclusion is discussed briefly and key implications for DOE planning are identified.

Coal Coal Index (click to jump links) Coal Production and Prices Coal Mining Labor Productivity Coal Consumption Coal Production and Prices Emissions Caps Lead to More Use of Low-Sulfur Coal From Western Mines Continued improvements in mine productivity (which have averaged 5.9 percent per year since 1980) are projected to cause falling real minemouth prices throughout the forecast relative to historical levels. Higher electricity demand and lower prices, in turn, are projected to yield increasing coal demand, but the demand is subject to the overall sulfur emissions cap in the Clean Air Act Amendments of 1990, which encourages progressively greater reliance on the lowest sulfur coals (from Wyoming, Montana, Colorado, and Utah).

Report to the United States Congress clean coal technology export markets and financing mechanisms  

SciTech Connect

This report responds to a Congressional Conference Report that requests that $625,000 in funding provided will be used by the Department to identify potential markets for clean coal technologies in developing countries and countries with economies in transition from nonmarket economies and to identify existing, or new, financial mechanisms or financial support to be provided by the Federal government that will enhance the ability of US industry to participate in these markets. The Energy Information Administration (EIA) expects world coal consumption to increase by 30 percent between 1990 and 2010, from 5.1 to 6.5 billion short tons. Five regions stand out as major foreign markets for the export of US clean coal technologies: China; The Pacific Rim (other than China); South Asia (primarily India); Transitional Economies (Central Europe and the Newly Independent States); and Other Markets (the Americas and Southern Africa). Nearly two-thirds of the expected worldwide growth in coal utilization will occur in China, one quarter in the United States. EIA forecasts nearly a billion tons per year of additional coal consumption in China between 1990 and 2010, a virtual doubling of that country`s coal consumption. A 30-percent increase in coal consumption is projected in other developing countries over that same period. This increase in coal consumption will be accompanied by an increase in demand for technologies for burning coal cost-effectively, efficiently and cleanly. In the Pacific Rim and South Asia, rapid economic growth coupled with substantial indigenous coal supplies combine to create a large potential market for CCTS. In Central Europe and the Newly Independent States, the challenge will be to correct the damage of decades of environmental neglect without adding to already-considerable economic disruption. Though the situation varies, all these countries share the basic need to use indigenous low-quality coal cleanly and efficiently.

Low-rank coal study. Volume 4. Regulatory, environmental, and market analyses  

Science Conference Proceedings (OSTI)

The regulatory, environmental, and market constraints to development of US low-rank coal resources are analyzed. Government-imposed environmental and regulatory requirements are among the most important factors that determine the markets for low-rank coal and the technology used in the extraction, delivery, and utilization systems. Both state and federal controls are examined, in light of available data on impacts and effluents associated with major low-rank coal development efforts. The market analysis examines both the penetration of existing markets by low-rank coal and the evolution of potential markets in the future. The electric utility industry consumes about 99 percent of the total low-rank coal production. This use in utility boilers rose dramatically in the 1970's and is expected to continue to grow rapidly. In the late 1980's and 1990's, industrial direct use of low-rank coal and the production of synthetic fuels are expected to start growing as major new markets.

Market assessment of environmental issues affecting coal use for Los Alamos National Laboratory  

SciTech Connect

This is a market assessment of environmental issues affecting coal use through 2020. It was prepared by Los Alamos National Laboratories for the Fossil Energy R&D Program. It is based on interviews of representatives of 8 coal, coal technology, electricity and environmental groups concerned with the future of energy and the environment. Interviewees generally agreed that the U.S. and other countries would continue to need to use coal into the middle of the next century. The size of the market for coal would be determined by the ability of coal and coal technologies to meet environmental requirements at costs that would compete with natural gas. Outside the U.S., three interviewees suggested that there is a market for low cost coal technologies that will reduce the environmental impact of coal use, particularly in developing countries that have few alternative sources of energy. The principal environmental concerns mentioned in these interviews were: efficiency and carbon, air toxics, and NO{sub x}. Several also mentioned potential modifications to the SO{sub x} standards, a fine particulate standard, bottom and fly ash, and methane from coalbeds.

Does the presence of pseudovitrinite indicate gas-saturated coals? Some interesting observations from the Gething coals in Canada  

Science Conference Proceedings (OSTI)

The presence of pseudovitrinite at a depth of 1,000 m in the very gassy (up to 862 scf/ton total gas content, as-received basis) but low absolute permeability (0.5 mD), low-volatile bituminous Gething coals in the Canadian Foothills has been documented. Because oxidation is unlikely to occur at such depth, it is reasonable to expect that pseudovitrinite formed as a result of desiccation in a gas-saturated environment prior to the coals being uplifted to their present day depth. This raises the possibility that a coal that contains pseudovitrinite may have moisture content that is below its equilibrium moisture, which leads to higher methane adsorptive capacity compared with the same coal that has normal vitrinite (collotelinite). The presence of inertinite macerals in the coal, derived from wood fibers and charred remnants, has aided in the development and preservation of phyteral porosity and in the formation of interconnected microcavities, which should result in higher micropermeability and aid the flow of gas locally within the coal seam and surrounding strata. The Gething coals in the Highhat corehole share some of these characteristics, which may have important implications on the dynamics of coal-bed methane production. Volumetric strain (matrix shrinkage) of these gassy coals during production is conservatively estimated to be 0.5-0.75%, which may result in an absolute permeability increase of between 5 to 12 times, based on studies on coals of similar rank and gas content in United States basins. Although observations made in this preliminary study do not constitute a proof, they leave open the possibility of using pseudovitrinite, under certain circumstances, as an indicator of improved gas sorptive capacity and enhanced permeability in deep coals.

We used data from a survey of 16493 West Virginians merged with county-level coal production and other covariates to investigate the relations between health indicators and residential proximity to coal mining. Results of hierarchical analyses indicated that high levels of coal production were associated with worse adjusted health status and with higher rates of cardiopulmonary disease, chronic obstructive pulmonary disease, hypertension, lung disease, and kidney disease. Research is recommended to ascertain the mechanisms, magnitude, and consequences of a community coal-mining exposure effect.

Potential markets for small coal-fired combustors in OECD countries: Country screening  

SciTech Connect

This report examines potential for use of US-developed advanced coal technology (ACT) for small combustor applications in foreign markets, in particular, the member countries of the Organization of Economic Co-operation and Development (OECD). After screening out OECD countries were evaluated on eight important factors favoring use of US ACT, including: the energy plan and/or situation; oil/gas import dependency; coal experience; residential/commercial energy demand; industrial energy demand; trade relations with the United States; lack of domestic competition in the country to US ACT manufacturers; and environmental pressure for use of advanced technology. Statistical and other information was gathered to support each country's rating---high, medium-high, low-medium, or low---for each factor. The country/factor ratings were then used to group the countries into categories indicating their relative potential as markets were found to exist in Spain, Italy, Turkey, Greece, and Canada. It was recommended that Spain, Italy, and Turkey be the subject of future studies, in which more detailed analysis will be made. 23 refs., 1 fig., 2 tabs.

Market effects of environmental regulation: coal, railroads, and the 1990 Clean Air Act  

Science Conference Proceedings (OSTI)

Many environmental regulations encourage the use of 'clean' inputs. When the suppliers of such an input have market power, environmental regulation will affect not only the quantity of the input used but also its price. We investigate the effect of the Title IV emissions trading program for sulfur dioxide on the market for low-sulfur coal. We find that the two railroads transporting coal were able to price discriminate on the basis of environmental regulation and geographic location. Delivered prices rose for plants in the trading program relative to other plants, and by more at plants near a low-sulfur coal source.

An analysis of markets for small-scale, advanced coal-combustion technology in Spain, Italy, and Turkey  

Science Conference Proceedings (OSTI)

This report discusses the examination of potential overseas markets for using small-scale, US-developed, advanced coal-combustion technologies (ACTs). In previous work, member countries of the Organization for Economic Cooperation and Development (OECD) were rated on their potential for using ACTs through a comprehensive screening methodology. The three most promising OECD markets were found to be Spain, Italy, and Turkey. This report provides in-depth analyses of these three selected countries. First, it addresses changes in the European Community with particular reference to the 1992 restructuring and its potential effect on the energy situation in Europe, specifically in the three subject countries. It presents individual country studies that examine demographics, economics, building infrastructures, and energy-related factors. Potential niches for ACTs are explored for each country through regional analyses. Marketing channels, strategies, and the trading environments in each country are also discussed. The information gathered indicates that Turkey is a most promising market, Spain is a fairly promising market, and Italy appears to be a somewhat limited market for US ACTs. 76 refs., 16 figs., 14 tabs.

Comparison of coal-based systems: marketability of medium-Btu gas and SNG (substitute natural gas) for industrial applications. Final report, July 1979-March 1982  

Science Conference Proceedings (OSTI)

In assessing the marketability of synthetic fuel gases from coal, this report emphasizes the determination of the relative attractiveness of substitute natural gas (SNG) and medium-Btu gas (MBG) for serving market needs in eight industrial market areas. The crucial issue in predicting the marketability of coal-based synthetic gas is the future price level of competing conventional alternatives, particularly oil. Under a low oil-price scenario, the market outlook for synthetic gases is not promising, but higher oil prices would encourage coal gasification.

Commercialization of coal diesel engines for non-utility and export power markets  

DOE Green Energy (OSTI)

The basic motivation behind this project is to develop coal-burning heat engine technology primarily for 10-100 MW modular stationary power applications in the late 1990`s and beyond, when oil and gas prices may return to the $5--7/MMBtu range. The fuel is a low-cost, coal-based liquid with the consistency of black paint, composed of 12-micron mean size premium 2% ash coal dust mixed 50/50 with water. The Clean Coal Diesel Plant of the future is targeted for the 10-100 MW non-utility generation (NUG) and small utility markets, including independent power producers (IPP) and cogeneration. A family of plant designs will be offered using the Cooper-Bessemer 3.8, 5.0, and 6.3 MW Model LS engines as building blocks. In addition, larger plants will be configured with an engine in the 10-25 MW class (Cooper will license the technology to other large bore stationary engine manufacturers). The reciprocating engine offers a remarkable degree of flexibility in selecting plant capacity. This flexibility exists because the engines are modular in every sense (fuel cell stacks have similar modularity). Scale-up is accomplished simply by adding cylinders (e.g., 20 vs 16) or by adding engines (4 vs 3). There is no scale-up of the basic cylinder size. Thus, there is essentially no technical development needed to scale-up the Cooper-Bessemer Clean Coal Diesel Technology all the way from 2 MW (one 6-cylinder engine) to 50 MW (eight 20-cylinder engines), other than engineering adaptation of the turbocharger to match the engine.

Clean coal technologies---An international seminar: Seminar evaluation and identification of potential CCT markets  

Science Conference Proceedings (OSTI)

The need for environmentally responsible electricity generation is a worldwide concern. Because coal is available throughout the world at a reasonable cost, current research is focusing on technologies that use coal with minimal environmental effects. The United States government is supporting research on clean coal technologies (CCTs) to be used for new capacity additions and for retrofits to existing capacity. To promote the worldwide adoption of US CCTs, the US Department of Energy, the US Agency for International Development, and the US Trade and Development Program sponsored a two-week seminar titled Clean Coal Technologies -- An International Seminar. Nineteen participants from seven countries were invited to this seminar, which was held at Argonne National Laboratory in June 1991. During the seminar, 11 US CCT vendors made presentations on their state-of-the-art and commercially available technologies. The presentations included technical, environmental, operational, and economic characteristics of CCTs. Information on financing and evaluating CCTs also was presented, and participants visited two CCT operating sites. The closing evaluation indicated that the seminar was a worthwhile experience for all participants and that it should be repeated. The participants said CCT could play a role in their existing and future electric capacity, but they agreed that more CCT demonstration projects were needed to confirm the reliability and performance of the technologies.

Analysis of market penetration scenarios of clean coal technologies in China using the LLNL China Energy Model  

SciTech Connect

This paper presents the results of an analysis of the market penetration of Clean Coal Technologies in the electric utility market in China. The analysis is based on a model of the Chinese energy system developed at Lawrence Livermore National Laboratory. Under this model, the market penetration of a technology depends on the relative prices of all technologies in a market. The model assumes that for each technology there is a distribution of effective prices to the consumers in the market place. The prices for each technology computed in the model are assumed to be the means of these distributions: sometime the effective price is greater than this and sometimes it is less. Thus even a relatively expensive technology may cost less than its competitors in a fraction of the transactions. Using several scenarios about the possible dispersion of prices, we estimate the market share of CCTs over the next 50 years. We find that some CCTs penetrate under all scenarios, but the more expensive ones only show significant penetration when larger values of price dispersion are assumed. Generally the penetration of the CCTs is 15% or less of the market by 2020. However, advanced pulverized coal does exceed 15% in some cases.

Assessment of underground coal gasification in bituminous coals: potential UCG products and markets. Final report, Phase I  

Science Conference Proceedings (OSTI)

The following conclusions were drawn from the study: (1) The US will continue to require new sources of energy fuels and substitutes for petrochemical feedstocks into the foreseeable future. Most of this requirement will be met using coal. However, the cost of mining, transporting, cleaning, and preparing coal, disposing of ash or slag and scrubbing stack gases continues to rise; particularly, in the Eastern US where the need is greatest. UCG avoids these pitfalls and, as such, should be considered a viable alternative to the mining of deeper coals. (2) Of the two possible product gases LBG and MBG, MBG is the most versatile. (3) The most logical use for UCG product in the Eastern US is to generate power on-site using a combined-cycle or co-generation system. Either low or medium Btu gas (LBG or MBG) can be used. (4) UCG should be an option whenever surface gasification is considered; particularly, in areas where deeper, higher sulfur coal is located. (5) There are environmental and social benefits to use of UCG over surface gasification in the Eastern US. (6) A site could be chosen almost anywhere in the Illinois and Ohio area where amenable UCG coal has been determined due to the existence of existing transportation or transmission systems. (7) The technology needs to be demonstrated and the potential economic viability determined at a site in the East-North-Central US which has commercial quantities of amenable bituminous coal before utilities will show significant interest.

Human capital theory predicts that individuals acquire less schooling when the returns to schooling are small. To test this theory, we study the effect of the coal boom in Appalachia on high school enrollments. During the 1970s, a boom in the coal industry increased the earnings of high school dropouts relative to graduates. During the 1980s, the boom subsided and the earnings of high school dropouts declined relative to graduates. We find that high school enrollment rates in Kentucky and Pennsylvania declined considerably in the 1970s and increased A simple model of human capital predicts that increases in the wages of workers with low education relative to workers with high education will reduce investments in schooling because the returns to additional years of schooling are diminished. In this paper, we exploit a particularly unique opportunity to study the effect of a decrease in the wage gap between high

Outlook and Challenges for Chinese Coal  

Science Conference Proceedings (OSTI)

China has been, is, and will continue to be a coal-powered economy. The rapid growth of coal demand since 2001 has created deepening strains and bottlenecks that raise questions about supply security. Although China's coal is 'plentiful,' published academic and policy analyses indicate that peak production will likely occur between 2016 and 2029. Given the current economic growth trajectory, domestic production constraints will lead to a coal gap that is not likely to be filled with imports. Urbanization, heavy industry growth, and increasing per-capita consumption are the primary drivers of rising coal usage. In 2006, the power sector, iron and steel, and cement accounted for 71% of coal consumption. Power generation is becoming more efficient, but even extensive roll-out of the highest efficiency units could save only 14% of projected 2025 coal demand. If China follows Japan, steel production would peak by 2015; cement is likely to follow a similar trajectory. A fourth wedge of future coal consumption is likely to come from the burgeoning coal-liquefaction and chemicals industries. New demand from coal-to-liquids and coal-to-chemicals may add 450 million tonnes of coal demand by 2025. Efficient growth among these drivers indicates that China's annual coal demand will reach 4.2 to 4.7 billion tonnes by 2025. Central government support for nuclear and renewable energy has not been able to reduce China's growing dependence on coal for primary energy. Few substitution options exist: offsetting one year of recent coal demand growth would require over 107 billion cubic meters of natural gas, 48 GW of nuclear, or 86 GW of hydropower capacity. While these alternatives will continue to grow, the scale of development using existing technologies will be insufficient to substitute significant coal demand before 2025. The central role of heavy industry in GDP growth and the difficulty of substituting other fuels suggest that coal consumption is inextricably entwined with China's economy in its current mode of growth. Ongoing dependence on coal reduces China's ability to mitigate carbon dioxide emissions growth. If coal demand remains on its current growth path, carbon dioxide emissions from coal combustion alone would exceed total US energy-related carbon emissions by 2010. Broadening awareness of the environmental costs of coal mining, transport, and combustion is raising the pressure on Chinese policy makers to find alternative energy sources. 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 is short of high-quality reserves, but is producing its best coal first. Declining quality will further strain production and transport. Transporting coal to users has overloaded the train system and dramatically increased truck use, raising transport oil demand. Growing international imports have helped to offset domestic transport bottlenecks. In the long term, import demand is likely to exceed 200 mt by 2025, significantly impacting regional markets. The looming coal gap threatens to derail China's growth path, possibly undermining political, economic, and social stability. High coal prices and domestic shortages will have regional and global effects. Regarding China's role as a global manufacturing center, a domestic coal gap will increase prices and constrain growth. Within the Asia-Pacific region, China's coal gap is likely to bring about increased competition with other coal-importing countries including Japan, South Korea, Taiwan, and India. As with petroleum, China may respond with a government-supported 'going-out' strategy of resource acquisition and vertical integration. Given its population and growing resource constraints, China may favor energy security, competitiveness, and local environmental protection over global climate change mitigation. The possibility of a large coal gap suggests that Chinese and international policy makers should maximize institutional and financial support

EIA - Future role of the United States in world coal trade  

Gasoline and Diesel Fuel Update (EIA)

Future role of the United States in world coal trade Future role of the United States in world coal trade International Energy Outlook 2010 Future role of the United States in world coal trade U.S. coal exports increased each year from 2002 to 2008 at an average annual rate of 12.8 percent, to 82 million tons in 2008. Some analysts have viewed the sharp increase in U.S. exports as an indication of the growing importance of the United States as a world coal supplier. There has also been speculation that China's growing demand for coal will support this trend in the future. However, U.S. coal is a relatively high-cost supply source when shipped to Asian markets, and in the long term U.S. coal will be competing in the Chinese market with lower cost suppliers, notably Australia and Indonesia among others. U.S. exports compete most strongly in European markets and then only when less expensive options are unavailable. In IEO2010, the United States remains a marginal coal supplier over the long term, responding to short-term disruptions or spikes in demand rather than significantly expanding its market share of world coal trade.

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

Coal sector profile  

SciTech Connect

Coal is our largest domestic energy resource with recoverable reserves estimated at 268 billion short tons or 5.896 quads Btu equivalent. This is approximately 95 percent of US fossil energy resources. It is relatively inexpensive to mine, and on a per Btu basis it is generally much less costly to produce than other energy sources. Its chief drawbacks are the environmental, health and safety concerns that must be addressed in its production and consumption. Historically, coal has played a major role in US energy markets. Coal fueled the railroads, heated the homes, powered the factories. and provided the raw materials for steel-making. In 1920, coal supplied over three times the amount of energy of oil, gas, and hydro combined. From 1920 until the mid 1970s, coal production remained fairly constant at 400 to 600 million short tons a year. Rapid increases in overall energy demands, which began during and after World War II were mostly met by oil and gas. By the mid 1940s, coal represented only half of total energy consumption in the US. In fact, post-war coal production, which had risen in support of the war effort and the postwar Marshall plan, decreased approximately 25 percent between 1945 and 1960. Coal demand in the post-war era up until the 1970s was characterized by increasing coal use by the electric utilities but decreasing coal use in many other markets (e.g., rail transportation). The oil price shocks of the 1970s, combined with natural gas shortages and problems with nuclear power, returned coal to a position of prominence. The greatly expanded use of coal was seen as a key building block in US energy strategies of the 1970s. Coal production increased from 613 million short tons per year in 1970 to 950 million short tons in 1988, up over 50 percent.

Integrated system for coal-methanol liquefaction and slurry pipeline transportation. Final report. [In slurry transport  

DOE Green Energy (OSTI)

The engineering economics of an integrated coal-to-methanol conversion system and coal-in-methanol transportation system are examined, under the circumstances of the western coalfields, i.e., long distances from major markets and scarcity of water in the vicinity of the mines. The transportation economics are attractive, indicating tariffs of approximately 40 cents per million Btu per thousand miles for the coal-methanol pipeline vs 60 cents via coal-water pipelines and upwards of a dollar via rail. Energy consumption is also less in the coal-methanol pipeline than in the coal-water pipeline, and about equal to rail. It is also concluded that, by a proper marriage of the synthetic fuel (methanolization) plant to the slurrification plant, most, and in some cases all, of the water required by the synthetic fuel process can be supplied by the natural moisture of the coal itself. Thus, the only technology which presently exists and by which synthetic fuel from western coal can displace petroleum in the automotive fuel market is the integrated methanol conversion and tranportation system. The key element is the ability of the methanol slurry pipeline to accept and to deliver dry (1 to 5% moisture) coal, allowing the natural coal moisture to be used as synthesis feedstock in satisfaction of the large water requirement of any synthetic fuel plant. By virtue of these unique properties, this integrated system is seen as the only means in the foreseeable future whereby western coal can be converted to synthetic fuel and moved to distant markets.

Pelletization of fine coals  

SciTech Connect

The present research project attempts to provide a basis to determine the pelletizability of fine coals, to ascertain the role of additives and binders and to establish a basis for binder selection. Currently, there are no established techniques for determining the quality of coal pellets. Our research is intended to develop a series of tests on coal pellets to measure their storage characteristics, transportability, ease of gasification and rate of combustion. Information developed from this research should be valuable for making knowledgeable decisions for on-time plant design, occasional binder selection and frequent process control during the pelletization of coal fines. During the last quarter, we continued the batch pelletization studies on Upper Freeport coal. The results as presented in that last quarterly report (April 1991) indicated that the surface conditions on the coal particle influenced the pelletizing growth rates. For example, a fresh (run of mine) sample of coal will display different pelletizing growth kinetics than a weathered sample of the same coal. Since coal is a heterogeneous material, the oxidized product of coal is equally variable. We found it to be logistically difficult to consistently produce large quantities of artificially oxidized coal for experimental purposes and as such we have used a naturally weathered coal. We have plans to oxidize coals under controlled oxidizing conditions and be able to establish their pelletizing behavior. The next phase of experiments were directed to study the effect of surface modification, introduced during the coal cleaning steps, on pelletizing kinetics. Accordingly, we initiated studies with two additives commonly used during the flotation of coal: dextrin (coal depressant) and dodecane (coal collector).

Estimating coal production peak and trends of coal imports in China  

SciTech Connect

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.

American coal imports 2015  

SciTech Connect

As 2007 ends, the US coal industry passes two major milestones - the ending of the Synfuel tax break, affecting over 100M st annually, and the imposition of tighter and much more expensive safety measures, particularly in deep mines. Both of these issues, arriving at a time of wretched steam coal price levels, promise to result in a major shake up in the Central Appalachian mining sector. The report utilizes a microeconomic regional approach to determine whether either of these two schools of thought have any validity. Transport, infrastructure, competing fuels and regional issues are examined in detail and this forecasts estimates coal demand and imports on a region by region basis for the years 2010 and 2015. Some of the major highlights of the forecast are: Import growth will be driven by steam coal demand in the eastern and southern US; Transport will continue to be the key driver - we believe that inland rail rates will deter imports from being railed far inland and that the great majority of imports will be delivered directly by vessel, barge or truck to end users; Colombian coal will be the overwhelmingly dominant supply source and possesses a costs structure to enable it to compete with US-produced coal in any market conditions; Most of the growth will come from existing power plants - increasing capacity utilization at existing import facilities and other plants making investments to add imports to the supply portfolio - the growth is not dependent upon a lot of new coal fired capacity being built. Contents of the report are: Key US market dynamics; International supply dynamics; Structure of the US coal import market; and Geographic analysis.

Clean coal technologies in Asia  

Science Conference Proceedings (OSTI)

Asia`s growing need for cleaner coal technology will likely translate into increased opportunities for independent developers and equipment suppliers. Coal is projected to play a central role in meeting Asia`s rapidly growing electric power demand. In order to minimize the negative effects of coal comsumption, the application of clean coal technologies (CCTs) will be increasingly important for the viability of coal-fired plants developed by independent power producers. The environmental impact of coal consumption has created a growing market for clean coal technologies in Asia. A study commissioned by the US DOE estimates the market for new and retrofit installation of coal facilities in Asia to be between $410 billion and $560 billion between 1993 and 2010. Actual expenditures for CCTs during the same period are likely to be much less, but still significant. Cost continues to be a factor limiting the more wide spread application of these technologies. In most cases, the application of CCTs leads to a 15 percent to 20 percent increase in capital costs and 10 to 20 percent in operating costs.

Market Organization and Market Efficiency in Electricity Markets  

E-Print Network (OSTI)

Electricity markets in the United States exhibit two different forms of organization: decentralized bilateral trading and centralized auction markets. Using detailed data on prices, quantities, and production costs, we examine how market outcomes changed when a large region in the Eastern US rapidly switched from a bilateral system of trade to a well-designed centralized auction market in 2004. Although economic theory yields ambiguous predictions, the empirical evidence indicates that shifting the venue of trade substantially improved overall market efficiency, and that these efficiency gains far exceeded implementation costs. Our analysis points to the merits of organized market institutions for electricity, a central issue in policy debates over market-oriented regulatory reforms.

Comparison of coal liquefaction processes. Final report on Task 006  

SciTech Connect

Five processes were studied to determine which could give best results for supplying hydrocarbon fuels to replace petroleum products. The processes were Fischer-Tropsch; M-Gasoline; H-Coal; Exxon Donor Solvent; and Solvent Refined Coal. The conclusions of the study are that all of the processes are considered commercially feasible and, because the different products from the different processes will meet different market demands, any significant future liquids from coal market will probably use some of each of these processes. The anticipated conversion efficiency values are given to indicate resource utilization. Simplified capital costs are approximated for each process. These are used in combination with product amounts and relative values to achieve a cost ranking. Because the study was concerned solely with liquid products, Fischer-Tropsch was at a disadvantage. The remaining four were relatively close and a final decision would depend upon the actual end use requirements. For a situation with residual fuels selling at severe discounts, M-Gasoline and H-Coal (Syncrude Mode) were the better choices.

Competitive interstate taxation of western coal  

SciTech Connect

This paper analyzes the potential market power of western states in setting coal severance taxes. An attempt to determine the emphasis placed by the western states on the development of their coal resources is also made. Three market structures are analyzed. One involves a western regional cartel, setting taxes collectively. The other cases are noncooperative tax equilibria with Montana and Wyoming competing against each other. We study the effects on these equilibria of changes in each region's relative emphasis on development of coal resources vs tax revenue. The welfare impacts of these tax setting policies are also addressed. The analysis is based on an activity analysis of US coal markets. The results show that the taxes associated with the noncooperative competitive tax equilibria are close to present tax levels. Additionally, we conclude that western states currently are quite efficient extractors of economic rent from coal produced within their boundaries, in terms of welfare loss per dollar of tax revenue collected. 2 figures.

Coal plasticity at high heating rates and temperatures  

SciTech Connect

Effects of coal type on coal plasticity are investigated. Seven coals, from the Argonne premium sample bank ranging from lignite to low volatile bituminous, are studied. Different indices and structural data of a coal are shown to affect its plastic behavior. A coal-specific parameter incorporating the effects of labile bridges, oxygen, and hydrogen on plasticity has been used to successfully correlate measured values of maximum plasticity (i.e. minimum apparent viscosity) at elevated temperature with coal type.

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.

China's Coal: Demand, Constraints, and Externalities  

Science Conference Proceedings (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.

Gasifier feed - Tailor-made from Illinois coals  

SciTech Connect

The main purpose of this project is to produce a feedstock from preparation plant fines from an illinois coal that is ideal for a slurry fed, slagging, entrained-flow coal gasifier. The high sulfur content and high Btu value of Illinois coals are particularly advantageous in such a gasifier; preliminary calculations indicate that the increased cost of removing sulfur from the gas from a high sulfur coal is more than offset by the increased revenue from the sale of the elemental sulfur; additionally the high Btu Illinois coal concentrates more energy into the slurry of a given coal to water ratio. The Btu is higher not only because of the higher Btu value of the coal but also because Illinois coal requires less water to produce a pumpable slurry than western coal, i.e., as little as 30--35% water may be used for Illinois coal as compared to approximately 45% for most western coals.

The coal-wind connection  

Science Conference Proceedings (OSTI)

The USA now has more than 10,000 MW of wind capacity and more wind farms are expected to be built. However transmissions constraints are great, especially in the Northwest and upper Midwest, where abundant wind resources span sparsely populated regions. These areas also hold major deposits of coal. Partnerships are being developed to share transmission to accommodate both new wind and new coal-fired capacity. Wyoming may well be the epicentre of the issue. Another idea, in wind-prone Texas, is to further integrate wind with baseload fossil power resources by creation of competitive renewable energy zones (CREZs). New transmission corridors will be set up linking the renewable energy zones to power markets in ERCOT, the Electric Reliability Council of Texas. There are problems of co-developing coal and wind capacity with common transmission. If coal gasification technology emerges on a commercial scale there would be a good opportunity for integrated gasification combined cycle which can cycle to firm up variable wind generation. Several coal companies in Wyoming are considering gasifying coal and putting it into the pipeline. 2 photos.

COAL SLAGGING AND REACTIVITY TESTING  

SciTech Connect

Union Fenosa's La Robla I Power Station is a 270-MW Foster Wheeler arch-fired system. The unit is located at the mine that provides a portion of the semianthracitic coal. The remaining coals used are from South Africa, Russia, Australia, and China. The challenges at the La Robla I Station stem from the various fuels used, the characteristics of which differ from the design coal. The University of North Dakota Energy & Environmental Research Center (EERC) and the Lehigh University Energy Research Center (LUERC) undertook a program to assess problematic slagging and unburned carbon issues occurring at the plant. Full-scale combustion tests were performed under baseline conditions, with elevated oxygen level and with redistribution of air during a site visit at the plant. During these tests, operating information, observations and temperature measurements, and coal, slag deposit, and fly ash samples were obtained to assess slagging and unburned carbon. The slagging in almost all cases appeared due to elevated temperatures rather than fuel chemistry. The most severe slagging occurred when the temperature at the sampling port was in excess of 1500 C, with problematic slagging where first-observed temperatures exceeded 1350 C. The presence of anorthite crystals in the bulk of the deposits analyzed indicates that the temperatures were in excess of 1350 C, consistent with temperature measurements during the sampling period. Elevated temperatures and ''hot spots'' are probably the result of poor mill performance, and a poor distribution of the coal from the mills to the specific burners causes elevated temperatures in the regions where the slag samples were extracted. A contributing cause appeared to be poor combustion air mixing and heating, resulting in oxygen stratification and increased temperatures in certain areas. Air preheater plugging was observed and reduces the temperature of the air in the windbox, which leads to poor combustion conditions, resulting in unburned carbon as well as slagging. A second phase of the project involved advanced analysis of the baseline coal along with an Australian coal fired at the plant. These analysis results were used in equilibrium thermodynamic modeling along with a coal quality model developed by the EERC to assess slagging, fouling, and opacity for the coals. Bench-scale carbon conversion testing was performed in a drop-tube furnace to assess the reactivity of the coals. The Australian coal had a higher mineral content with significantly more clay minerals present than the baseline coal. The presence of these clay minerals, which tend to melt at relatively low temperatures, indicated a higher potential for problematic slagging than the baseline coal. However, the pyritic minerals, comprising over 25% of the baseline mineral content, may form sticky iron sulfides, leading to severe slagging in the burner region if local areas with reducing conditions exist. Modeling results indicated that neither would present significant fouling problems. The Australian coal was expected to show slagging behavior much more severe than the baseline coal except at very high furnace temperatures. However, the baseline coal was predicted to exhibit opacity problems, as well as have a higher potential for problematic calcium sulfate-based low-temperature fouling. The baseline coal had a somewhat higher reactivity than the Australian coal, which was consistent with both the lower average activation energy for the baseline coal and the greater carbon conversion at a given temperature and residence time. The activation energy of the baseline coal showed some effect of oxygen on the activation energy, with E{sub a} increasing at the lower oxygen concentration, but may be due to the scatter in the baseline coal kinetic values at the higher oxygen level tested.

Clean coal: Global opportunities for small businesses  

Science Conference Proceedings (OSTI)

The parallel growth in coal demand and environmental concern has spurred interest in technologies that burn coal with greater efficiency and with lower emissions. Clean Coal Technologies (CCTs) will ensure that continued use of the world`s most abundant energy resource is compatible with a cleaner, healthier environment. Increasing interest in CCTs opens the door for American small businesses to provide services and equipment for the clean and efficient use of coal. Key players in most coal-related projects are typically large equipment manufacturers, power project developers, utilities, governments, and multinational corporations. At the same time, the complexity and scale of many of these projects creates niche markets for small American businesses with high-value products and services. From information technology, control systems, and specialized components to management practices, financial services, and personnel training methods, small US companies boast some of the highest value products and services in the world. As a result, American companies are in a prime position to take advantage of global niche markets for CCTs. This guide is designed to provide US small businesses with an overview of potential international market opportunities related to CCTs and to provide initial guidance on how to cost-effectively enter that growing global market.

CO2 Sequestration Potential of Texas Low-Rank Coals  

SciTech Connect

Injection of CO{sub 2} in coalbeds is a plausible method of reducing atmospheric emissions of CO{sub 2}, and it can have the additional benefit of enhancing methane recovery from coal. Most previous studies have evaluated the merits of CO{sub 2} disposal in high-rank coals. The objective of this research was to determine the technical and economic feasibility of CO{sub 2} sequestration in, and enhanced coalbed methane (ECBM) recovery from, low-rank coals in the Texas Gulf Coast area. Our research included an extensive coal characterization program, including acquisition and analysis of coal core samples and well transient test data. We conducted deterministic and probabilistic reservoir simulation and economic studies to evaluate the effects of injectant fluid composition (pure CO{sub 2} and flue gas), well spacing, injection rate, and dewatering on CO{sub 2} sequestration and ECBM recovery in low-rank coals of the Calvert Bluff formation of the Texas Wilcox Group. Shallow and deep Calvert Bluff coals occur in two, distinct, coalbed gas petroleum systems that are separated by a transition zone. Calvert Bluff coals < 3,500 ft deep are part of a biogenic coalbed gas system. They have low gas content and are part of a freshwater aquifer. In contrast, Wilcox coals deeper than 3,500 ft are part of a thermogenic coalbed gas system. They have high gas content and are part of a saline aquifer. CO{sub 2} sequestration and ECBM projects in Calvert Bluff low-rank coals of East-Central Texas must be located in the deeper, unmineable coals, because shallow Wilcox coals are part of a protected freshwater aquifer. Probabilistic simulation of 100% CO{sub 2} injection into 20 feet of Calvert Bluff coal in an 80-acre 5-spot pattern indicates that these coals can store 1.27 to 2.25 Bcf of CO{sub 2} at depths of 6,200 ft, with an ECBM recovery of 0.48 to 0.85 Bcf. Simulation results of flue gas injection (87% N{sub 2}-13% CO{sub 2}) indicate that these same coals can store 0.34 to 0.59 Bcf of CO{sub 2} with an ECBM recovery of 0.68 to 1.20 Bcf. Economic modeling of CO{sub 2} sequestration and ECBM recovery indicates predominantly negative economic indicators for the reservoir depths (4,000 to 6,200 ft) and well spacings investigated, using natural gas prices ranging from $2 to $12 per Mscf and CO{sub 2} credits based on carbon market prices ranging from $0.05 to $1.58 per Mscf CO{sub 2} ($1.00 to $30.00 per ton CO{sub 2}). Injection of flue gas (87% N{sub 2} - 13% CO{sub 2}) results in better economic performance than injection of 100% CO{sub 2}. CO{sub 2} sequestration potential and methane resources in low-rank coals of the Lower Calvert Bluff formation in East-Central Texas are significant. The potential CO{sub 2} sequestration capacity of the coals ranges between 27.2 and 49.2 Tcf (1.57 and 2.69 billion tons), with a mean value of 38 Tcf (2.2 billion tons), assuming a 72.4% injection efficiency. Estimates of recoverable methane resources range between 6.3 and 13.6 Tcf, with a mean of 9.8 Tcf, assuming a 71.3% recovery factor. Moderate increases in gas prices and/or carbon credits could generate attractive economic conditions that, combined with the close proximity of many CO{sub 2} point sources near unmineable coalbeds, could enable commercial CO{sub 2} sequestration and ECBM projects in Texas low-rank coals. Additional studies are needed to characterize Wilcox regional methane coalbed gas systems and their boundaries, and to assess potential of other low-rank coal beds. Results from this study may be transferable to other low-rank coal formations and regions.

The potential CO{sub 2} sequestration capacity of the coals ranges between 27.2 and 49.2 Tcf (1.57 and 2.69 billion tons), with a mean value of 38 Tcf (2.2 billion tons), assuming a 72.4% injection efficiency. Estimates of recoverable methane resources range between 6.3 and 13.6 Tcf, with a mean of 9.8 Tcf, assuming a 71.3% recovery factor. Moderate increases in gas prices and/or carbon credits could generate attractive economic conditions that, combined with the close proximity of many CO{sub 2} point sources near unmineable coalbeds, could enable commercial CO{sub 2} sequestration and ECBM projects in Texas low-rank coals. Additional studies are needed to characterize Wilcox regional methane coalbed gas systems and their boundaries, and to assess potential of other low-rank coal beds. Results from this study may be transferable to other low-rank coal formations and regions.

Controlling Energy Costs with Coal Conversion  

E-Print Network (OSTI)

Even with a decade of substantial energy reduction in America's manufacturing plants and a temporary 'oil glut', energy often represents the largest plant expense, higher than labor or raw materials. Energy is not only a major plant expense; it is usually regarded as the most controllable. Fluidized bed combustion technology allows industrial steam users to use low-grade coals that are outside of mainstream coal markets, are abundant, and are very inexpensive, being one-quarter to one-third the price of oil or gas. This paper discusses the economics of low-grade coal, what is fluidized bed technology and its comparison to conventional coal and gas/oil fired systems, and one coal-fired FBC installation in Texas.

Kinetics of coal pyrolysis  

Science Conference Proceedings (OSTI)

This report contains results of a coordinated, multi-laboratory investigation of coal devolatilization. Data is reported pertaining to the devolatilization for bituminous coals over three orders of magnitude in apparent heating rate (100 to 100,000 + {degree}C/sec), over two orders of magnitude in particle size (20 to 700 microns), final particle temperatures from 400 to 1600{degree}C, heat transfer modes ranging from convection to radiative, ambient pressure ranging from near vacuum to one atmosphere pressure. The heat transfer characteristics of the reactors are reported in detail. It is assumed the experimental results are to form the basis of a devolatilization data base. Empirical rate expressions are developed for each phase of devolatilization which, when coupled to an awareness of the heat transfer rate potential of a particular devolatilization reactor, indicate the kinetics emphasized by a particular system reactor plus coal sample. The analysis indicates the particular phase of devolatilization that will be emphasized by a particular reactor type and, thereby, the kinetic expressions appropriate to that devolatilization system. Engineering rate expressions are developed from the empirical rate expressions in the context of a fundamental understanding of coal devolatilization developed in the course of the investigation. 164 refs., 223 figs., 44 tabs.

Forecasting of mine price for central Appalachian steam coal  

SciTech Connect

In reaction to Virginia's declining share of the steam coal market and the subsequent depression in southwest Virginia's economy, an optimization model of the central Appalachian steam coal market was developed. The input to the cost vector was the delivered cost of coal, which is comprised of the mine price (FOB) and transportation cost. One objective of the study was to develop a purchasing model that could be used to minimize the cost of coal procurement over a multi-period time span. The initial case study used a six-month period (7/86-12/86); this requires short-term, forecasts of the mine price of coal. Mine-cost equations and regression models were found to be inadequate for forecasting the mine price of coal. Instead forecasts were generated using modified time series models. This paper describes the application of classical time-series modeling to forecasting the mine price of coal in central Appalachia; in particular, the special modification to the classical methodology needed to generate short-term forecasts and their confidence limits and the need to take into account market-specific considerations such as the split between long-term contracts and the spot market. Special consideration is given to forecasting the spot market. 7 references, 4 figures, 3 tables.

Novel carbons from Illinois coal for natural gas storage. Technical report, March 1--May 31, 1995  

DOE Green Energy (OSTI)

Goal is to develop a technology for producing microengineered adsorbent carbons from Illinois coal and to evaluate their potential application for storing natural gas for use in emerging low pressure, natural gas vehicles (NGVs). Focus is to design and engineer adsorbents that meet or exceed performance and cost targets established for low-pressure natural gas storage materials. Potentially, about two million tons adsorbent could be consumed in NGVs by year 2000. If successful, the results could lead to use of Illinois coal in a market that could exceed 6 million tons per year. Activated carbon samples were prepared from IBC-106 coal by controlling both the preoxidation temperature and time, and the devolatilization temperature in order to eliminate coal caking. A 4.6 cc pressurized vessel was constructed to measure the Vm/Vs methane adsorption capacity (volume of stored methane at STP per volume storage container). Several IBC-106 derived activated carbons showed methane adsorption capacities comparable to that of a 1000 m{sup 2}/g commercial activated carbon. Results indicated that surface area and micropore volume of activated carbons are important for natural gas storage. Work is in progress to synthesize samples from IBC-106 coal with optimum pore diameter for methane adsorption.

Oxidative decomposition of formaldehyde catalyzed by a bituminous coal  

Science Conference Proceedings (OSTI)

It has been observed that molecular hydrogen is formed during long-term storage of bituminous coals via oxidative decomposition of formaldehyde by coal surface peroxides. This study has investigated the effects of coal quantity, temperature, and water content on the molecular hydrogen formation with a typical American coal (Pittsburgh No. 6). The results indicate that the coal's surface serves as a catalyst in the formation processes of molecular hydrogen. Furthermore, the results also indicate that low temperature emission of molecular hydrogen may possibly be the cause of unexplained explosions in confined spaces containing bituminous coals, for example, underground mines or ship holds. 20 refs., 4 figs., 6 tabs.

Alaska Coal Geology: GIS Data | OpenEI  

Open Energy Info (EERE)

Coal Geology: GIS Data Coal Geology: GIS Data Dataset Summary Description Estimated Alaska coal resources are largely in Cretaceous and Tertiary rocks distributed in three major provinces. Northern Alaska-Slope, Central Alaska-Nenana, and Southern Alaska-Cook Inlet. Cretaceous resources, predominantly bituminous coal and lignite, are in the Northern Alaska-Slope coal province. Most of the Tertiary resources, mainly lignite to subbituminous coal with minor amounts of bituminous and semianthracite coals, are in the other two provinces. The combined measured, indicated, inferred, and hypothetical coal resources in the three areas are estimated to be 5,526 billion short tons (5,012 billion metric tons), which constitutes about 87 percent of Alaska's coal and surpasses the total coal resources of the conterminous United States by 40 percent.

The good news is that market stability can be achieved through a combination of longer-term contracts, auctions for far enough in the future to permit new entry, a capacity management system, and a demand curve. The bad news is that if and when stable capacity markets are designed, the markets may seem to be relatively close to where we started - with integrated resource planning.

The crude oil market has been both quieter and thinner during the past few months. Various factors, including OPEC restraints, settlement of the British coal strike, and dollar exchange rates, have been stabilizing, although erratic output by Iran and the Soviet Union have caused fluctuations in prices. Higher gasoline prices have triggered a preference for sweet crudes and a possible shortage during the summer motoring season. Oil stocks appear to be at the bottom now, but restocking activities will probably not cause shortages. The author forecasts a continued weak market. 2 tables.

Preparation for upgrading western subbituminous coal  

SciTech Connect

The objective of this project was to establish the physical and chemical characteristics of western coal and determine the best preparation technologies for upgrading this resource. Western coal was characterized as an abundant, easily mineable, clean, low-sulfur coal with low heating value, high moisture, susceptibility to spontaneous ignition, and considerable transit distances from major markets. Project support was provided by the Morgantown Energy Technology Center (METC) of the US Department of Energy (DOE). The research was conducted by the Western Research Institute, (WRI) in Laramie, Wyoming. The project scope of work required the completion of four tasks: (1) project planning, (2) literature searches and verbal contacts with consumers and producers of western coal, (3) selection of the best technologies to upgrade western coal, and (4) identification of research needed to develop the best technologies for upgrading western coals. The results of this research suggest that thermal drying is the best technology for upgrading western coals. There is a significant need for further research in areas involving physical and chemical stabilization of the dried coal product. Excessive particle-size degradation and resulting dustiness, moisture reabsorption, and high susceptibility to spontaneous combustion are key areas requiring further research. Improved testing methods for the determination of equilibrium moisture and susceptibility to spontaneous ignition under various ambient conditions are recommended.

Coal gasification  

Science Conference Proceedings (OSTI)

A standard series of two staged gas generators (GG) has been developed in the United States for producing gas with a combustion heat from 4,700 to 7,600 kilojoules per cubic meter from coal (U). The diameter of the gas generators is from 1.4 to 3.65 meters and the thermal capacity based on purified cold gas is from 12.5 to 89 million kilojoules per hour. Certain standard sized gas generators have undergone experimental industrial tests which showed that it is most expedient to feed the coal into the gas generators pneumatically. This reduces the dimensions of the charging device, makes it possible to use more common grades of structural steels and reduces the cost of the gas. A double valve reliably prevents ejections of the gasification product and promotes the best distribution of the coal in the gas generator. The gas generators may successfully operate on high moisture (up to 36 percent) brown coal. Blasting with oxygen enriched to 38 percent made it possible to produce a gas with a combustion heat of 9,350 kilojoules per cubic meter. This supports a combustion temperature of 1,700C.

Lummus clean fuels from coal  

DOE Green Energy (OSTI)

This report compares two direct, catalytic, hydroliquefaction processes - H-Coal and Lummus Clean Fuels From Coal (LCFFC). These processes are compared for two sets of operating conditions. In the first, the reactors are operated to produce a product suitable for use as fuel oil (fuel oil mode). In the second, the operating conditions are more severe, so the resulting product slates more closely resemble crude oil (syncrude mode). The comparisons are performed using conceptual designs based on single point run data, with a design basis of 25,000 tpd (moisture-free basis) of Illinois No. 6 coal. Although all cost comparisons are well within the estimated 25% accuracy of the estimates, LCFFC shows generally lower costs. Three types of economic evaluation are performed: computation of internal rate of return (IRR) with product values set to estimated market value, computation of overall average product cost ($/MM Btu) with the discount rate set at 20%, and calculation of average product cost with naphtha credited at estimated market value and the discount rate set at 20%. H-Coal has a lower cost only in the fuel oil mode analysis with naphtha valued at market price. The processes are also compared with respect to the potential for commercialization and anticipated operability differences. It is concluded that the lower hydrogen content of LCFFC product may offset its advantage of lower cost if it is used as refinery feed, and that the design of the LCFFC reactor may make it harder to control. Suggestions for future research are presented.

A study of the interfacial chemistry of pyrite and coal in fine coal cleaning using flotation  

SciTech Connect

Surface oxidation, surface charge, and flotation properties have been systematically studied for coal, coal-pyrite and ore-pyrite. Electrochemical studies show that coal-pyrite exhibits much higher and more complex surface oxidation than ore-pyrite and its oxidation rate depends strongly on the carbon/coal content. Flotation studies indicate that pyrites have no self-induced floatability. Fuel oil significantly improves the floatability of coal and induces considerable flotation for coal-pyrite due to the hydrophobic interaction of fuel oil with the carbon/coal inclusions on the pyrite surface. Xanthate is a good collector for ore-pyrite but a poor collector for coal and coal-pyrite. The results from thermodynamic calculations, flotation and zeta potential measurements show that iron ions greatly affect the flotation of pyrite with xanthate and fuel oil. Various organic and inorganic chemicals have been examined for depressing coal-pyrite. It was found, for the first time, that sodium pyrophosphate is an effective depressant for coal-pyrite. Solution chemistry shows that pyrophosphate reacts with iron ions to form stable iron pyrophosphate complexes. Using pyrophosphate, the complete separation of pyrite from coal can be realized over a wide pH range at relatively low dosage.

The US Department of Energy's anthracite and residential coal programs are described. The residential coal effort is an outgrowth and extension of the anthracite program, which has been, and continues to be, involved in promoting increased production and use of anthracite and the restoration of anthracite as a viable economic alternative to soft coals and to imported oil and gas now supplying the Northeast. Since anthracite is a preferred fuel for residential heating, residential coal issues comprise an important part of our anthracite activities. We have commenced a study of residential coal utilization including: overview of the residential coal market; market potential for residential coal use; analysis of the state of technology, economics, constraints to increased use of coal and coal-based fuels in residential markets, and identification of research and development activities which would serve to increase the market potential for coal-fired residential systems. A considerable amount of information is given in this report on residential coal furnaces and coal usage in 1974, prices of heating oils and coal, methods of comparing these fuels (economics), air pollution, safety, wood and wood furnaces, regulations, etc.

Available information on potential markets for photovoltaic power systems is reviewed. A set of key parameters which affect the rate of photovoltaic market penetration is used to develop a simple anaytical structure that characterizes potential markets. Completed studies on photovoltaic markets were reviewed to describe potential markets using this structure. Selected markets were then examined in greater detail in a market demand workshop attended by potential purchasers in these markets. Available information, while sufficient to provide a rudimentary indication of how markets might develop, does not allow the construction of any single market scenario in which a high level of confidence can be placed. Major uncertainties in the available information on photovoltaic markets are highlighted.

Underground Coal Thermal Treatment  

Science Conference Proceedings (OSTI)

The long-term objective of this work is to develop a transformational energy production technology by insitu thermal treatment of a coal seam for the production of substitute natural gas (SNG) while leaving much of the coalâ??s carbon in the ground. This process converts coal to a high-efficiency, low-GHG emitting gas fuel. It holds the potential of providing environmentally acceptable access to previously unusable coal resources. This topical report discusses the development of experimental capabilities, the collection of available data, and the development of simulation tools to obtain process thermo-chemical and geo-thermal parameters in preparation for the eventual demonstration in a coal seam. It also includes experimental and modeling studies of CO{sub 2} sequestration. Efforts focused on: â?¢ Constructing a suite of three different coal pyrolysis reactors. These reactors offer the ability to gather heat transfer, mass transfer and kinetic data during coal pyrolysis under conditions that mimic in situ conditions (Subtask 6.1). â?¢ Studying the operational parameters for various underground thermal treatment processes for oil shale and coal and completing a design matrix analysis for the underground coal thermal treatment (UCTT). This analysis yielded recommendations for terms of targeted coal rank, well orientation, rubblization, presence of oxygen, temperature, pressure, and heating sources (Subtask 6.2). â?¢ Developing capabilities for simulating UCTT, including modifying the geometry as well as the solution algorithm to achieve long simulation times in a rubblized coal bed by resolving the convective channels occurring in the representative domain (Subtask 6.3). â?¢ Studying the reactive behavior of carbon dioxide (CO{sub 2}) with limestone, sandstone, arkose (a more complex sandstone) and peridotite, including mineralogical changes and brine chemistry for the different initial rock compositions (Subtask 6.4). Arkose exhibited the highest tendency of participating in mineral reactions, which can be attributed to the geochemical complexity of its initial mineral assemblage. In experiments with limestone, continuous dissolution was observed with the release of CO{sub 2} gas, indicated by the increasing pressure in the reactor (formation of a gas chamber). This occurred due to the lack of any source of alkali to buffer the solution. Arkose has the geochemical complexity for permanent sequestration of CO{sub 2} as carbonates and is also relatively abundant. The effect of including NH{sub 3} in the injected gas stream was also investigated in this study. Precipitation of calcite and trace amounts of ammonium zeolites was observed. A batch geochemical model was developed using Geochemists Workbench (GWB). Degassing effect in the experiments was corrected using the sliding fugacity model in GWB. Experimental and simulation results were compared and a reasonable agreement between the two was observed.

Fuel cell market applications  

DOE Green Energy (OSTI)

This is a review of the US (and international) fuel cell development for the stationary power generation market. Besides DOE, GRI, and EPRI sponsorship, the US fuel cell program has over 40% cost-sharing from the private sector. Support is provided by user groups with over 75 utility and other end-user members. Objectives are to develop and demonstrate cost-effective fuel cell power generation which can initially be commercialized into various market applications using natural gas fuel by the year 2000. Types of fuel cells being developed include PAFC (phosphoric acid), MCFC (molten carbonate), and SOFC (solid oxide); status of each is reported. Potential international applications are reviewed also. Fuel cells are viewed as a force in dispersed power generation, distributed power, cogeneration, and deregulated industry. Specific fuel cell attributes are discussed: Fuel cells promise to be one of the most reliable power sources; they are now being used in critical uninterruptible power systems. They need hydrogen which can be generated internally from natural gas, coal gas, methanol landfill gas, or other fuels containing hydrocarbons. Finally, fuel cell development and market applications in Japan are reviewed briefly.

Assessment of coal liquids as refinery feedstocks  

Science Conference Proceedings (OSTI)

The R D of direct coal liquefaction has reached such a stage that current two-stage processes can produce coal liquids with high yields and improved quality at a reasonable cost. To fully realize the potential value, these coal liquids should be refined into high-value liquid transportation fuels. The purpose of this study is to assess coal liquids as feedstocks to be processed by modern petroleum refining technologies. After the introduction, Section 2.0 summarizes ASTM specifications for major transportation fuels: gasoline, jet fuel, and diesel fuel, which serve as a target for coal-liquid refining. A concise description of modern refining processes follows with an emphasis on the requirements for the raw materials. These provide criteria to judge the quality of coal liquids as a refinery feedstock for the production of marketable liquid fuels. Section 3.0 surveys the properties of coal liquids produced by various liquefaction processes. Compared with typical petroleum oils, the current two-stage coal liquids are: Light in boiling range and free of resids and metals; very low in sulfur but relatively high in oxygen; relatively low in hydrogen and high in cyclics content; and essentially toxicologically inactive when end point is lower than 650[degrees]F, particularly after hydroprocessing. Despite these characteristics, the coal liquids are basically similar to petroleum. The modern refining technology is capable of processing coal liquids into transportation fuels meeting all specifications, and hydroprocessinq is obviously the major tool. The important point is the determination of a reasonable product slate and an appropriate refining scheme.

Coal-fired diesel generator  

SciTech Connect

The objective of the proposed project is to test the technical, environmental, and economic viability of a coal-fired diesel generator for producing electric power in small power generating markets. Coal for the diesel generator would be provided from existing supplies transported for use in the University`s power plant. A cleanup system would be installed for limiting gaseous and particulate emissions. Electricity and steam produced by the diesel generator would be used to supply the needs of the University. The proposed diesel generator and supporting facilities would occupy approximately 2 acres of land adjacent to existing coal- and oil-fired power plant and research laboratory buildings at the University of Alaska, Fairbanks. The environmental analysis identified that the most notable changes to result from the proposed project would occur in the following areas: power plant configuration at the University of Alaska, Fairbanks; air emissions, water use and discharge, and the quantity of solid waste for disposal; noise levels at the power plant site; and transportation of coal to the power plant. No substantive adverse impacts or environmental concerns were identified in analyzing the effects of these changes.

Survey of government assistance for the world's hard-coal industries  

Science Conference Proceedings (OSTI)

This report investigates the existence and use of subsidies and incentives that foreign nations give their coal industries. Of particular interest are those aids that promote and facilitate the export of coal. A survey of hard coal producing countries was conducted to compile, and quantify if possible, direct and indirect financial aids given by governments for the purposes of maintaining, expanding or creating an indigenous coal industry and facilitating exports. The survey found that government measures commonly used to maintain, expand or create coal production include deficit operating grants, capital grants, preferential loan credits, labor and tax benefits, and export marketing assistance. Typical measures used to guarantee and protect domestic coal markets are long-term supply agreements, price supports, government purchases, tariffs, import licenses, and quotas. Common types of financial assistance provided by governments that do not benefit current coal production or use are research and development funds, environmental grants for restoring past mined lands, and payments to unemployed miners.

Clean Coal Technology Program Clean Coal Technology Program Clean Coal 101 Lesson 2: The Clean Coal Technology Program The Clean Coal Technology Program began in 1985 when the United States and Canada decided that something had to be done about the "acid rain" that was believed to be damaging rivers, lakes, forests, and buildings in both countries. Since many of the pollutants that formed "acid rain" were coming from big coal-burning power plants in the United States, the U.S. Government took the lead in finding a solution. One of the steps taken by the U.S. Department of Energy was to create a partnership program between the Government, several States, and private companies to test new methods developed by scientists to make coal burning much cleaner. This became the "Clean Coal Technology Program."

Crime Indicators  

E-Print Network (OSTI)

data collection efforts are used to gauge the problem of crime in America. These two data series are intended to measure different aspects of crime, but this point is often lost in the front-page headline summaries of whether crime is “up,” “down, ” or about the same. Confusion regarding the two crime indicators is exacerbated when the two data series show substantially different trends, as was the case with the most recent release of data in 2001. For this column, we asked Michael Rand and Callie Rennison of the U.S. Bureau of Justice Statistics to describe the two national crime indicators and their differences. Their article clearly describes the distinct approaches to measuring crime used by these two data series, and provides a strong justification for maintaining these two approaches to address very distinct policy needs. Just a thought... A previous Window on Washington column from summer 1998 discussed the U.S. Census Bureau’s Small-Area Income and Poverty Estimates Program, which used administrative records and census data in conjunction with Current Population Survey estimates to produce modelbased small-area estimates that incorporated information from all these sources. It would be interesting to see if a similar approach might be used to provide small-area estimates of violent crime, possibly by fitting a regression model to the National Crime Victimization Survey data, using the Uniform Crime Reports and other data as explanatory variables. Such approaches to combine information from the two national crime indicators—continuing efforts to refine inferences from two frequently confused data series—are interesting possibilities for future research.

Market potential of IGCC for domestic power production  

SciTech Connect

Mitretek Systems and CONSOL Inc. have completed the first phase of a market potential study for Integrated Coal Gasification Combined Cycle (IGCC) domestic power production. The U. S. Department of Energy (DOE) funded this study. The objective of this study is to provide DOE with data to estimate the future domestic market potential of IGCC for electricity generation. Major drivers in this study are the state of technology development, feedstock costs, environmental control costs, demand growth, and dispatchability. This study examines IGCC potential for baseload power production in the Northeast U. S., an important market area by virtue of existing coal infrastructure and proximity to coal producing regions. IGCC market potential was examined for two levels of technology development as a function of natural gas price and carbon tax. This paper discusses the results of this study, including the levels of performance and cost necessary to insure competitiveness with natural gas combined cycle plants.

MOLECULAR ACCESSIBILITY IN OXIDIZED AND DRIED COALS  

DOE Green Energy (OSTI)

Changes in physical and chemical structure of the micropore system in eight solvent swelled Argonne Premium Coal Sample (APCS) coals upon weathering were studied using the EPR spin probe method. Spin probes, which are allowed to diffuse into the coal structure during swelling, are trapped when the swelling solvent is removed. Excess spin probes are removed from the coal surface and larger pores so that only the presence of spin probes trapped in pores which closely approximate the size of the spin probe are detected. Detailed explanations and illustrations of the experimental procedure used are given. Careful examination of the weathering process on coal as a function of rank was accomplished using the EPR spin probe method. The retention of spin probes in eight APCS coals provided valuable insight into both the loss of water and the oxidation which occur during the weathering process. The results could be explained in terms of the autoxidation process observed in other polymeric systems. It was shown that initial oxidation of coal can result in increased cross-linking in the coal structure. As the oxidation process continued, both the covalent and hydrogen bonded character of the coal were significantly altered. The retention character of some coals during oxidation was shown to change by as much as three orders of magnitude. Experiments were performed to study the effects of short term oxidation and dehydration on coal structure by exposing the coal samples to argon or oxygen for time periods up to five minutes. The results indicate that the structure of coal is extremely sensitive to environmental changes and exhibits significant changes in as little as 30 seconds. Exposure of Illinois No.6 coal to argon or oxygen for 30 seconds caused a decrease in the retention of polar spin probes by as much as an order of magnitude. The studies presented here suggest that the structure of coal is dynamic in nature, and has an intimate relationship with the nature of its environment. This method has been shown to be very sensitive to structural changes brought about in coal by oxidation and dehydration, and can be used to follow changes in coal during the swelling process. Additional ideas for future studies using the EPR spin probe method are also discussed.

Comparison of biomass and coal char reactivities  

SciTech Connect

Char combustion is typically the rate limiting step during the combustion of solid fuels. The magnitude and variation of char reactivity during combustion are, therefore, of primary concern when comparing solid fuels such as coal and biomass. In an effort to evaluate biomass` potential as a sustainable and renewable energy source, the reactivities of both biomass and coal chars were compared using Sandia`s Captive Particle Imaging (CPI) apparatus. This paper summarizes the experimental approach used to determine biomass and coal reactivities and presents results from CPT experiments. The reactivity of six types of char particles, two high-rank coal chars, two low-rank coal chars, and two biomass chars, were investigated using the CPT apparatus. Results indicate that both of the high-rank coal chars have relatively low reactivities when compared with the higher reactivities measured for the low-rank coal and the biomass chars. In addition, extinction behavior of the chars support related investigations that suggest carbonaceous structural ordering is an important consideration in understanding particle reactivity as a function of extent of burnout. High-rank coal chars were found to have highly ordered carbon structures, where as, both low-rank coal and biomass chars were found to have highly disordered carbon structures.

Evaluation of coal pretreatment prior to co-processing  

SciTech Connect

The Western Research Institute is currently developing a mild gasification process for the recovery of a stabilized char product for use as a fuel. A liquid product of limited value is produced during the mild gasification process that may be suited as a co-processing vehicle for coal-oil co-processing. Research was conducted to evaluate co-processing of this mild gasification liquid with coal. The two major areas of research discussed in this report are: (1) coal pretreatment with a coal-derived liquid to induce coal swelling and promote catalyst dispersion and (2) co-processing coal that has been thermally pretreated in the presence of the mild gasification liquid. The results of the investigation to evaluate co-processing of coal that has been thermally pretreated in the presence of the mild gasification liquid indicate that the thermal pretreatment adversely affected the coal-oil co-processing under hydrogen pressure. Thermally pretreated coals co-processed under a hydrogen atmosphere and without benefit of catalyst exhibited about 86 wt % conversion as compared to 96 wt % for coal that was only thermally dried. The addition of the iron pentacarbonyl catalyst precursor to the thermally pretreated coals did improve the conversion to near that of the dried coal. Results from analysis of the product obtained from co-processing the Illinois No. 6 coal showed it was upgraded in terms of oxygen content and hydrogen to carbon atomic ratio when compared to the mild gasification liquid.

Geographic market suitability analysis for low- and intermediate-temperature solar IPH systems  

DOE Green Energy (OSTI)

Previous studies of the industrial market for solar energy systems have considered the level of solar radiation as the main determinant of geographic markets in the US. This study evaluates geographical markets extensively based on such criteria as output of different types of low- and intermediate-temperature solar thermal collectors, air quality constraints for competitive fuels, state solar tax incentives, fuel costs, low industrial use of coal, high industrial growth areas, and industry energy consumption in different parts of the US. Market suitability analysis and mapping techniques, refined in the past 20 years by land use planners, were used to evaluate geographical markets. A computer-aided system, Generalized Map Analysis Planning System (GMAPS), performed interactive, cellular, computer mapping, and composite mapping. Results indicate that the US Southwest and West are the most attractive geographical markets for solar IPH, based on an equal weighting of the evaluation criteria. The West North-Central and East South-Central regions appear to have the least attractive markets. Specific areas within states where solar IPH systems have distinct marketing advantages also are apparent from the composite maps. However, when different weights are assigned to the various criteria, the results change significantly for some regions of the country, such as the New England, Mid-Atlantic, and West South-Central 2 regions. The results of this work will become less valid in the future as state incentives for solar IPH, air quality regulations, and the status of competitive fuels all change. Volume I contains study results and maps.

Affecting Policy by Manipulating Prediction Markets: Experimental Evidence 1  

E-Print Network (OSTI)

Documented results indicate prediction markets effectively aggregate information and form accurate predictions. This has led to a proliferation of markets predicting everything from the results of elections to a company’s sales to movie box office receipts. Recent research suggests prediction markets are robust to manipulation attacks and resulting market outcomes improve forecast accuracy. However, we present evidence from the lab indicating that well funded, single minded manipulators can in fact destroy a prediction market’s ability to aggregate information. Our results clearly indicate that the usefulness of prediction markets as inputs to decision making may be limited.

Coal data: A reference  

SciTech Connect

This report, Coal Data: A Reference, summarizes basic information on the mining and use of coal, an important source of energy in the US. This report is written for a general audience. The goal is to cover basic material and strike a reasonable compromise between overly generalized statements and detailed analyses. The section ``Supplemental Figures and Tables`` contains statistics, graphs, maps, and other illustrations that show trends, patterns, geographic locations, and similar coal-related information. The section ``Coal Terminology and Related Information`` provides additional information about terms mentioned in the text and introduces some new terms. The last edition of Coal Data: A Reference was published in 1991. The present edition contains updated data as well as expanded reviews and additional information. Added to the text are discussions of coal quality, coal prices, unions, and strikes. The appendix has been expanded to provide statistics on a variety of additional topics, such as: trends in coal production and royalties from Federal and Indian coal leases, hours worked and earnings for coal mine employment, railroad coal shipments and revenues, waterborne coal traffic, coal export loading terminals, utility coal combustion byproducts, and trace elements in coal. The information in this report has been gleaned mainly from the sources in the bibliography. The reader interested in going beyond the scope of this report should consult these sources. The statistics are largely from reports published by the Energy Information Administration.

Analysis & Projections Analysis & Projections ‹ See all Coal Reports U.S. Coal Supply and Demand: 2010 Year in Review Release Date: June 1, 2011 | Next Release Date: Periodically | full report Exports and Imports Exports Total U.S. coal exports for 2010 increased by 38.3 percent to 81.7 million short tons (Figure 8). Figure Data This increase was largely due to two factors. First, heavy rains and flooding in Australia, Indonesia, and Colombia reduced world coal supply and forced many coal importing nations to look elsewhere, primarily to the United States, to fulfill their coal needs. In addition, the shortage of their own domestic coal in relation to growing needs, namely for China and India, provided ample opportunities for U.S. coal producers to export to these markets.

Combustion characterization of coals for industrial applications  

Science Conference Proceedings (OSTI)

The five parent coals ear-marked for this study have been characterized. These coals include (1) a Texas (Wilcox) lignite; (2) a Montana (Rosebud) subbituminous; (4) an Alabama (Black Creek) high volatile bituminous; and (5) a Pennsylvania (Buck Mountain) anthracite. Samples for analyses were prepared in accordance with the ASTM standard (ASTM D 2013-72). The following ASTM analyses were performed on each coal: proximate, ultimate, higher heating value, Hardgrove grindability index, ash fusibility, and ash composition. Additionally, the flammability index (FI) of each coal was determined in an in-house apparatus. The FI is indicative of the ignition temperature of a given fuel on a relative basis. The combustion kinetic parameters (apparent activation energies and frequency factors) of Montana subbituminous and Pennsylvania anthracite chars have also been derived from data obtained in the Drop Tube Furnace System (DTFS). This information depicts the combustion characteristics of these two coal chars. 1 ref., 5 figs., 4 tabs.

BOILER MATERIALS FOR ULTRASUPERCRITICAL COAL POWER PLANTS  

SciTech Connect

The principal objective of this project is to develop materials technology for use in ultrasupercritical (USC) plant boilers capable of operating with 760 C (1400 F), and up to 5500 psi with emphasis upon 35 MPa (5000 psi) steam. In the 21st century, the world faces the critical challenge of providing abundant, cheap electricity to meet the needs of a growing global population while at the same time preserving environmental values. Most studies of this issue conclude that a robust portfolio of generation technologies and fuels should be developed to assure that the United States will have adequate electricity supplies in a variety of possible future scenarios. The use of coal for electricity generation poses a unique set of challenges. On the one hand, coal is plentiful and available at low cost in much of the world, notably in the U.S., China, and India. Countries with large coal reserves will want to develop them to foster economic growth and energy security. On the other hand, traditional methods of coal combustion emit pollutants and CO{sub 2} at high levels relative to other generation options. Maintaining coal as a generation option in the 21st century will require methods for addressing these environmental issues. This project has established a government/industry consortium to undertake a five-year effort to evaluate and develop advanced materials that allow the use of advanced steam cycles in coal-based power plants. These advanced cycles, with steam temperatures up to 760 C, will increase the efficiency of coal-fired boilers from an average of 35% efficiency (current domestic fleet) to 47% (HHV). This efficiency increase will enable coal-fired power plants to generate electricity at competitive rates (irrespective of fuel costs) while reducing CO{sub 2} and other fuel-related emissions by as much as 29%. Success in achieving these objectives will support a number of broader goals. First, from a national prospective, the program will identify advanced materials that will make it possible to maintain a cost-competitive, environmentally-acceptable coal-based electric generation option. High sulfur coals will specifically benefit in this respect by having these advanced materials evaluated in high-sulfur coal firing conditions and from the significant reductions in waste generation inherent in the increased operational efficiency. Second, from a national perspective, the results of this program will enable domestic boiler manufacturers to successfully compete in world markets for building high-efficiency coal-fired power plants.

Investigations into coal coprocessing and coal liquefaction  

DOE Green Energy (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.

Market power analysis in the EEX electricity market : an agent-based simulation approach.  

Science Conference Proceedings (OSTI)

In this paper, an agent-based modeling and simulation (ABMS) approach is used to model the German wholesale electricity market. The spot market prices in the European Energy Exchange (EEX) are studied as the wholesale market prices. Each participant in the market is modeled as an individual rationality-bounded agent whose objective is to maximize its own profit. By simulating the market clearing process, the interaction among agents is captured. The market clearing price formed by agentspsila production cost bidding is regarded as the reference marginal cost. The gap between the marginal cost and the real market price is measured as an indicator of possible market power exertion. Various bidding strategies such as physical withholding and economic withholding can be simulated to represent strategic bidding behaviors of the market participants. The preliminary simulation results show that some generation companies (GenCos) are in the position of exerting market power by strategic bidding.

Process for heating coal-oil slurries  

DOE Patents (OSTI)

Controlling gas to slurry volume ratio to achieve a gas holdup of about 0.4 when heating a flowing coal-oil slurry and a hydrogen containing gas stream allows operation with virtually any coal to solvent ratio and permits operation with efficient heat transfer and satisfactory pressure drops. The critical minimum gas flow rate for any given coal-oil slurry will depend on numerous factors such as coal concentration, coal particle size distribution, composition of the solvent (including recycle slurries), and type of coal. Further system efficiency can be achieved by operating with multiple heating zones to provide a high heat flux when the apparent viscosity of the gas saturated slurry is highest. Operation with gas flow rates below the critical minimum results in system instability indicated by temperature excursions in the fluid and at the tube wall, by a rapid increase and then decrease in overall pressure drop with decreasing gas flow rate, and by increased temperature differences between the temperature of the bulk fluid and the tube wall. At the temperatures and pressures used in coal liquefaction preheaters the coal-oil slurry and hydrogen containing gas stream behaves essentially as a Newtonian fluid at shear rates in excess of 150 sec[sup [minus]1]. The gas to slurry volume ratio should also be controlled to assure that the flow regime does not shift from homogeneous flow to non-homogeneous flow. Stable operations have been observed with a maximum gas holdup as high as 0.72. 29 figs.

Economics and market potential of hydrogen production  

DOE Green Energy (OSTI)

A study was undertaken to evaluate the economics of producing hydrogen from coal and from water and to assess the market potential for this hydrogen in chemical and fuel applications. Results of this study are summarized. Current chemical applications of hydrogen in manufacturing ammonia and methanol, in refining petroleum and in specialty uses provide a base market for penetration by new hydrogen production technologies, although prospects for the use of hydrogen in fuel applications remain unclear. Electrolysis and coal gasification will be complementary, not competitive, technologies for producing hydrogen. Coal gasification plants are better suited to production of large quantities of hydrogen, while electrolyzers are better suited to the production of hydrogen for small-scale uses. Hydrogen produced through coal gasification may be economical in chemical applications (e.g., ammonia production) by the late 1990's. Development programs now underway are expected to provide new coal gasification technologies with lower first costs and higher efficiencies than current technologies. An on-site coal gasification plant supplying hydrogen in the quantities usually required in chemical applications (from 10 to 100 million cubic feet per day) will be smaller than is generally proposed for syngas plants. Growth in smaller scale specialty uses of hydrogen and improvements in the technology for electrolysis will create conditions favorable to expanded use of hydrogen produced through water electrolysis. The major constraint on use of electrolysis will be the availability of low cost electricity. Shortages of natural gas caused by declining domestic production could induce shifts to producing hydrogen through electrolysis or through coal gasification earlier in time (i.e., the late 1980's or early 1990's) than is suggested by comparative cost calculations alone.

Coal char fragmentation during pulverized coal combustion  

Science Conference Proceedings (OSTI)

A series of investigations of coal and char fragmentation during pulverized coal combustion is reported for a suite of coals ranging in rank from lignite to low-volatile (lv) bituminous coal under combustion conditions similar to those found in commercial-scale boilers. Experimental measurements are described that utilize identical particle sizing characteristics to determine initial and final size distributions. Mechanistic interpretation of the data suggest that coal fragmentation is an insignificant event and that char fragmentation is controlled by char structure. Chars forming cenospheres fragment more extensively than solid chars. Among the chars that fragment, large particles produce more fine material than small particles. In all cases, coal and char fragmentation are seen to be sufficiently minor as to be relatively insignificant factors influencing fly ash size distribution, particle loading, and char burnout.

The Upgraded Coal Interest Group (UCIG) is an EPRI 'users group' that focuses on clean, low-cost options for coal-based power generation. The UCIG covers topics that involve (1) pre-combustion processes, (2) co-firing systems and fuels, and (3) reburn using coal-derived or biomass-derived fuels. The UCIG mission is to preserve and expand the economic use of coal for energy. By reducing the fuel costs and environmental impacts of coal-fired power generation, existing units become more cost effective and thus new units utilizing advanced combustion technologies are more likely to be coal-fired.

The coal feed lock comprises a rotor member with a diametral bore therethrough. A hydraulically activated piston is slidably mounted in the bore. With the feed lock in a charging position, coal is delivered to the bore and then the rotor member is rotated to a discharging position so as to communicate with the gas producer. The piston pushes the coal into the gas producer. The rotor member is then rotated to the charging position to receive the next load of coal.

Liquid Tin Anode Direct Coal Fuel Cell Final Program Report  

SciTech Connect

This SBIR program will result in improved LTA cell technology which is the fundamental building block of the Direct Coal ECL concept. As described below, ECL can make enormous efficiency and cost contributions to utility scale coal power. This program will improve LTA cells for small scale power generation. As described in the Commercialization section, there are important intermediate military and commercial markets for LTA generators that will provide an important bridge to the coal power application. The specific technical information from this program relating to YSZ electrolyte durability will be broadly applicable SOFC developers working on coal based SOFC generally. This is an area about which very little is currently known and will be critical for successfully applying fuel cells to coal power generation.

Novel carbons from Illinois coal for natural gas storage. Technical report, September 1--November 30, 1994  

DOE Green Energy (OSTI)

The goal of this project is to develop a technology for producing microengineered adsorbent carbons from Illinois coal and to evaluate the potential application of these novel materials for storing natural gas for use in emerging low pressure, natural gas vehicles (NGV). Potentially, about two million tons of adsorbent could be consumed in natural gas vehicles by year 2000. If successful, the results obtained in this project could lead to the use of Illinois coal in a growing and profitable market that could exceed 6 million tons per year. During this reporting period, a pyrolysis-gasification reactor system was designed and assembled. Four carbon samples were produced from a {minus}20+100 mesh size fraction of an Illinois Basin Coal (IBC-106) using a three-step process. The three steps were: coal oxidation in air at 250 C, oxicoal (oxidized coal) devolatilization in nitrogen at 425 C and char gasification in 50% steam-50% nitrogen at 860 C. These initial tests were designed to evaluate the effects of pre-oxidation on the surface properties of carbon products, and to determine optimum reaction time and process conditions to produce an activated carbon with high surface area. Nitrogen-BET surface areas of the carbon products ranged from 700--800 m{sup 2}/g. Work is in progress to further optimize reaction conditions in order to produce carbons with higher surface areas. A few screening tests were made with a pressurized thermogravimetric (PTGA) to evaluate the suitability of this instrument for obtaining methane adsorption isotherms at ambient temperature and pressures ranging from one to 30 atmospheres. The preliminary results indicate that PTGA can be used for both the adsorption kinetic and equilibrium studies.

Essays on Efficiency of the Farm Credit System and Dynamic Correlations in Fossil Fuel Markets  

E-Print Network (OSTI)

Markets have always changed in response to either exogenous or endogenous shocks. Many large events have occurred in financial and energy markets the last ten years. This dissertation examines market behavior and volatility in agricultural credit and fossil fuel markets under exogenous and endogenous changes in the last ten years. The efficiency of elements within the United States Farm Credit System, a major agricultural lender in the United States, and the dynamic correlation between coal, oil and natural gas prices, the three major fossil fuels, are examined. The Farm Credit system is a key lender in the U.S. agricultural sector, and its performance can influence the performance of the agricultural sector. However, its efficiency in providing credit to the agricultural sector has not been recently examined. The first essay of the dissertation provides assessments on the performance of elements within the Farm Credit System by measuring their relative efficiency using a stochastic frontier model. The second essay addresses the changes in relationship in coal, oil, and natural gas markets with respect to changes and turbulence in the last decade, which has also not been fully addressed in literature. The updated assessment on the relative performance of entities within the Farm Credit System provides information that the Farm Credit Administration and U.S. policy makers can use in their management of and policy toward the Farm Credit System. The measurement of the changes in fossil fuel markets’ relationships provides implications for energy investment, energy portfolio anagement, energy risk management, and energy security. It can also be used as a foundation for structuring forecasting models and other models related to energy markets. The dynamic correlations between coal, oil, and natural gas prices are examined using a dynamic conditional correlation multivariate autoregressive conditional heteroskedasticity (MGARCH DCC) model. The estimated results show that the FCS’s five banks and associations with large assets have more efficiently produced credit to the U.S. agricultural sector than smaller sized associations. Management compensation is found to be positively associated with the system’s efficiency. More capital investment and monitoring along with possible consolidation are implied for smaller sized associations to enhance efficiency. On average, the results show that the efficiency of the associations is increasing over time while the average efficiency of the five large banks is more stable. Overall, the associations exhibit a higher variation of efficiency than the five banks. In terms of energy markets the estimates from the MGARCH DCC model indicate significant and changing dynamic correlations and related volatility between the coal, oil, and natural gas prices. The coal price was found to experience more volatility and become more closely related to oil and natural gas prices in recent periods. The natural gas price was found to become more stable and drift away from its historical relationship with oil.

Soviets welcome advanced coal mining technology  

SciTech Connect

The coal production target for the Soviet Union for 1985 is 770 - 800 million tonnes. In 1981, surface mining provided 38% of output, this should increase to 40% by 1985. Soviet coal reserves are quoted as 8.6 x 10/sup 12/ tons, of which 90% are in the east. Many of the deposits are in areas where climate and transportation pose major problems. The location of the principal coal deposits is shown and their reserves are indicated. The emphasis in future production will be on surface mining, in very large units.

Hard truths: facing the hard truths about energy. Topic Paper No. 1: Coal impact  

Science Conference Proceedings (OSTI)

The United States has the largest coal reserves in the world, followed by Russia and China. Coal now provides about a quarter of the energy used in the United States. The share of US energy to be supplied by coal is projected to increase modestly to 2030. Coal use worldwide exhibits the same characteristics as in the United States. The largest increase in coal use through 2030 is projected to be in China, followed by the United States and India. Coal is consumed in large quantities throughout the United States, while most production is focussed in a few states, requiring significant quantities of coal to be transported long distances. To that end US coal consumers and producers have access to the world's most comprehensive and efficient coal transportation system. The extent to which coal is able to help meet future US energy challenges will depend heavily on the performance of coal transporters. Contents are: United States coal market; supply growth; demand growth; US coal transportation infrastructure: issues and prospects; and other factors impacting supply/demand growth. 25 figs., 12 tabs., 1 app.

Coal-fueled high-speed diesel engine development. Final report, September 28, 1990--November 30, 1993  

DOE Green Energy (OSTI)

The goal of this program was to study the feasibility of operating a Detroit Diesel Series 149 engine at high speeds using a Coal-Water-Slurry (CWS) fuel. The CWS-fueled 149 engine is proposed for the mine-haul off-highway truck and work boat marine markets. Economic analysis studies indicate that, for these markets, the use of CWS fuel could have sufficient operating cost savings, depending upon the future diesel fuel price, emission control system capital and operating costs, and maintenance and overhaul costs. A major portion of the maintenance costs is expected to be due to lower life and higher cost of the CWS injectors. Injection and combustion systems were specially designed for CWS, and were installed in one cylinder of a Detroit Diesel 8V-149TI engine for testing. The objective was to achieve engine operation for sustained periods at speeds up to 1,900 rpm with reasonable fuel economy and coal burnout rate. A computer simulation predicted autoignition of coal fuel at 1,900 rpm would require an average droplet size of 18 microns and 19:1 compression ratio, so the injection system, and pistons were designed accordingly. The injection system was capable of supplying the required volume of CWS/injection with a duration of approximately 25 crank angle degrees and peak pressures on the order of 100 mpa. In addition to the high compression ratio, the combustion system also utilized hot residual gases in the cylinder, warm inlet air admission and ceramic insulated engine components to enhance combustion. Autoignition of CWS fuel was achieved at 1900 rpm, at loads ranging from 20--80 percent of the rated load of diesel-fuel powered cylinders. Limited emissions data indicates coal burnout rates in excess of 99 percent. NO{sub x} levels were significantly lower, while unburned hydrocarbon levels were higher for the CWS fueled cylinder than for corresponding diesel-fuel powered cylinders.

Advanced coal-fueled industrial cogeneration gas turbine system. Annual report, 2 June 1992--1 June 1993  

SciTech Connect

This program was initiated in June of 1986 because advances in coal-fueled gas turbine technology over the previous few years, together with DOE-METC sponsored studies, served to provide new optimism that the problems demonstrated in the past can be economically resolved and that the coal-fueled gas turbine could ultimately be the preferred system in appropriate market application sectors. In early 1991 it became evident that a combination of low natural gas prices, stringent emission limits of the Clean Air Act and concerns for CO{sub 2} emissions made the direct coal-fueled gas turbine less attractive. In late 1991 it was decided not to complete this program as planned. The objective of the Solar/METC program was to prove the technical, economic, and environmental feasibility of a coal-fired gas turbine for cogeneration applications through tests of a Centaur Type H engine system operated on coal fuel throughout the engine design operating range. Component development of the coal-fueled combustor island and cleanup system while not complete indicated that the planned engine test was feasible. Preliminary designs of the engine hardware and installation were partially completed. A successful conclusion to the program would have initiated a continuation of the commercialization plan through extended field demonstration runs. After notification of the intent not to complete the program a replan was carried out to finish the program in an orderly fashion within the framework of the contract. A contract modification added the first phase of the Advanced Turbine Study whose objective is to develop high efficiency, natural gas fueled gas turbine technology.

Eisenbeis, Supt. of Conservation THE FIRST COAL PLANTS Coal has been called "the mainspring" of our civilization. You are probably familiar, in a general way, with the story of how it originated ages ago from beds of peat which were very slowly changed to coal; and how it became lignite or brown coal, sub-bituminous, bituminous, or anthracite coal, depending on bacterial and chemical changes in the peat, how much it was compressed under terrific pressure, and the amount of heat involved in the process. You also know that peat is formed by decaying vegetation in shallow clear fresh-water swamps or bogs, but it is difficult to find a simple description of the kinds of plants that, living and dying during different periods of the earth's history, created beds of peat which eventually became coal.

Overview of coal conversion  

SciTech Connect

The structure of coal and the processes of coal gasification and coal liquefaction are reviewed. While coal conversion technology is not likely to provide a significant amount of synthetic fuel within the next several years, there is a clear interest both in government and private sectors in the development of this technology to hedge against ever-diminishing petroleum supplies, especially from foreign sources. It is evident from this rather cursory survey that there is some old technology that is highly reliable; new technology is being developed but is not ready for commercialization at the present state of development. The area of coal conversion is ripe for exploration both on the applied and basic research levels. A great deal more must be understood about the reactions of coal, the reactions of coal products, and the physics and chemistry involved in the various stages of coal conversion processes in order to make this technology economically viable.

Oxidation of coal and coal pyrite mechanisms and influence on surface characteristics. Technical progress report, [June--August 1993  

SciTech Connect

The objective of this research is to develop a mechanistic understanding of the oxidation of coal and coal pyrite, and to correlate the intrinsic physical and chemical properties of these minerals, along with changes resulting from oxidation, with those surface properties that influence the behavior in physical cleaning processes. The results will provide fundamental insight into oxidation, in term of the bulk and surface chemistry, the microstructure, and the semiconductor properties of the pyrite. During the twelfth quarter, wet and dry oxidation tests were done at room temperature on coal samples from the Pennsylvania State Coal Bank. Previous results had indicated that oxidation at high temperatures induced changes in surface properties through loss of volatiles. As-received and oxidized coal samples were studied by ion exchange methods to determine the carboxylate and phenolic group concentrations. Film flotation tests were done to characterize the floatability of as-received and oxidized coals. Surface area measurements were done on as-received coals.

Mild coal pretreatment to improve liquefaction reactivity  

SciTech Connect

This report describes work completed during the fifth quarter of a three year project to study the effects of mild chemical pretreatment on coal dissolution reactivity during low severity liquefaction or coal/oil coprocessing. The overall objective of this research is to elucidate changes in the chemical and physical structure of coal by pretreating with methanol or other simple organic solvent and a trace amount of hydrochloric acid and measure the influence of these changes on coal dissolution reactivity. Work this quarter focused on analytical characterization of untreated and treated Wyodak subbituminous coal and Illinois {number sign}6 bituminous coal. Mossbauer spectroscopy and x-ray diffraction techniques were used to study the effect of methanol/HCl pretreatment on the composition of each coal's inorganic phase. Results from these studies indicated that calcite is largely removed during pretreatment, but that other mineral species such as pyrite are unaffected. This finding is significant, since calcite removal appears to directly correlate with low severity liquefaction enhancement. Further work will be performed to study this phenomenon in more detail.

Coal: the new black  

SciTech Connect

Long eclipsed by oil and natural gas as a raw material for high-volume chemicals, coal is making a comeback, with oil priced at more than $100 per barrel. It is relatively cheap feedstock for chemicals such as methanol and China is building plants to convert coal to polyolefins on a large scale and interest is spreading worldwide. Over the years several companies in the US and China have made fertilizers via the gasification of coal. Eastman in Tennessee gasifies coal to make methanol which is then converted to acetic acid, acetic anhydride and acetate fiber. The future vision is to convert methanol to olefins. UOP and Lurgi are the major vendors of this technology. These companies are the respective chemical engineering arms of Honeywell and Air Liquide. The article reports developments in China, USA and India on coal-to-chemicals via coal gasification or coal liquefaction. 2 figs., 2 photo.

Coal distribution, January-March 1985. [By district; 1981 to 1985  

Science Conference Proceedings (OSTI)

US coal distribution to domestic and foreign markets totaled 210.8 million short tons in the first quarter of 1985. This was 5.1% below coal shipments in the first quarter of 1984, but 10.7% above the depressed levels of the comparable period in 1983. Coal shipments to various regions of the United States and abroad showed mixed trends during the first 3 months of 1985. This is attributable primarily to large inventory buildups by eastern and midwestern consumers during the first 9 months of 1984 in preparation for a possible strike by the United Mine Workers of America in October of last year. Coal inventories at producers and distributors rose by 3.1% during the first quarter of 1985, reaching 35.2 million short tons on March 31, 1985, compared to 34.1 million short tons on December 31, 1984. Compared with the first quarter of 1984: Coal shipments from mines in Appalachia were 12.6% lower, while shipments from western mines were up by 9.7%, reaching another record first-quarter high. Export shipments moved ahead of their 1984 pace by 9.9% despite a 30.0% decline in shipments to Canada. Major markets in the West continued to enlarge their coal requirements as eastern markets curtailed shipments while working off excess stocks. Texas expanded its lead as the Nation's top state to receive coal, and North Dakota experienced an upsurge in coal receipts due to the startup of the Great Plains coal gasification project. Coal production and purchases were 211.5 million short tons, 5.0% below last year's level. The reduction in shipments reflected a substantial decline in coal originating in the Appalachian Region, notably District 8, and to a lesser extent in the Interior Region. In contrast, shipments of coal from the Western Region reached another first-quarter high. 5 figs., 33 tabs.

Corn/coal fuel characterization study  

DOE Green Energy (OSTI)

Laboratory analyses and tests were conducted to determine the suitability of shelled corn as a potential supplemental fuel for pulverized coal fired utility boilers. The analyses and tests used were those routinely used for the characterization of coal. The data indicated very high volatility and very low ash. Corn by itself would not be a suitable fuel for conventional boilers, primarily because of the severe fouling and slagging potential of corn ash. Blends of corn and coal minimized the fouling and slagging problems. The blend samples contained 10% corn by BTU or 14% by weight. Approximately 1.05 pounds of this blend would provide the heat equivalent of one pound of coal. The additional fuel input would place an additional load on fuel handling and preparation equipment, but the decrease in ash quantity would reduce the load on ash handling and particulate-type flue gas clean-up equipment.

Survey and evaluation of current and potential coal beneficiation processes  

SciTech Connect

Coal beneficiation is a generic term used for processes that prepare run-of-mine coal for specific end uses. It is also referred to as coal preparation or coal cleaning and is a means of reducing the sulfur and the ash contents of coal. Information is presented regarding current and potential coal beneficiation processes. Several of the processes reviewed, though not yet commercial, are at various stages of experimental development. Process descriptions are provided for these processes commensurate with the extent of information and time available to perform the evaluation of these processes. Conceptual process designs, preliminary cost estimates, and economic evaluations are provided for the more advanced (from a process development hierarchy viewpoint) processes based on production levels of 1500 and 15,000 tons/day (maf) of cleaned product coal. Economic evaluations of the coal preparation plants are conducted for several project financing schemes and at 12 and 15% annual after-tax rates of return on equity capital. A 9% annual interest rate is used on the debt fraction of the plant capital. Cleaned product coal prices are determined using the discounted cash flow procedure. The study is intended to provide information on publicly known coal beneficiation processes and to indicate the relative costs of various coal beneficiation processes. Because of severe timeconstraints, several potential coal beneficiation processes are not evaluated in great detail. It is recommended that an additional study be conducted to complement this study and to more fully appreciate the potentially significant role of coal beneficiation in the clean burning of coal.

Biological upgrading of coal liquids. Final report  

SciTech Connect

A large number of bacterial enrichments have been developed for their ability to utilize nitrogen and sulfur in coal liquids and the model compound naphtha. These bacteria include the original aerobic bacteria isolated from natural sources which utilize heteroatom compounds in the presence of rich media, aerobic nitrogen-utilizing bacteria and denitrifying bacteria. The most promising isolates include Mix M, a mixture of aerobic bacteria; ER15, a pyridine-utilizing isolate; ERI6, an aniline-utilizing isolate and a sewage sludge isolate. Culture optimization experiments have led to these bacteria being able to remove up to 40 percent of the sulfur and nitrogen in naphtha and coal liquids in batch culture. Continuous culture experiments showed that the coal liquid is too toxic to the bacteria to be fed without dilution or extraction. Thus either semi-batch operation must be employed with continuous gas sparging into a batch of liquid, or acid extracted coal liquid must be employed in continuous reactor studies with continuous liquid flow. Isolate EN-1, a chemical waste isolate, removed 27 percent of the sulfur and 19 percent of the nitrogen in fed batch experiments. Isolate ERI5 removed 28 percent of the nitrogen in coal liquid in 10 days in fed batch culture. The sewage sludge isolate removed 22.5 percent of the sulfur and 6.5 percent of the nitrogen from extracted coal liquid in continuous culture, and Mix M removed 17.5 percent of the nitrogen from medium containing extracted coal liquid. An economic evaluation has been prepared for the removal of nitrogen heteroatom compounds from Wilsonville coal liquid using acid extraction followed by fermentation. Similar technology can be developed for sulfur removal. The evaluation indicates that the nitrogen heteroatom compounds can be removed for $0.09/lb of coal liquid treated.

Development and Testing of Industrial Scale Coal Fired Combustion System, Phase 3  

SciTech Connect

Coal Tech Corp's mission is to develop, license & sell innovative, lowest cost, solid fuel fired power systems & total emission control processes using proprietary and patented technology for domestic and international markets. The present project 'DEVELOPMENT & TESTING OF INDUSTRIAL SCALE, COAL FIRED COMBUSTION SYSTEM, PHASE 3' on DOE Contract DE-AC22-91PC91162 was a key element in achieving this objective. The project consisted of five tasks that were divided into three phases. The first phase, 'Optimization of First Generation 20 MMBtu/hr Air-Cooled Slagging Coal Tech Combustor', consisted of three tasks, which are detailed in Appendix 'A' of this report. They were implemented in 1992 and 1993 at the first generation, 20 MMBtu/hour, combustor-boiler test site in Williamsport, PA. It consisted of substantial combustor modifications and coal-fired tests designed to improve the combustor's wall cooling, slag and ash management, automating of its operation, and correcting severe deficiencies in the coal feeding to the combustor. The need for these changes was indicated during the prior 900-hour test effort on this combustor that was conducted as part of the DOE Clean Coal Program. A combination of combustor changes, auxiliary equipment changes, sophisticated multi-dimensional combustion analysis, computer controlled automation, and series of single and double day shift tests totaling about 300 hours, either resolved these operational issues or indicated that further corrective changes were needed in the combustor design. The key result from both analyses and tests was that the combustor must be substantially lengthened to maximize combustion efficiency and sharply increase slag retention in the combustor. A measure of the success of these modifications was realized in the third phase of this project, consisting of task 5 entitled: 'Site Demonstration with the Second Generation 20 MMBtu/hr Air-Cooled Slagging Coal Tech Combustor'. The details of the task 5 effort are contained in Appendix 'C'. It was implemented between 1994 and 1998 after the entire 20 MMBtu/hr combustor-boiler facility was relocated to Philadelphia, PA in 1994. A new test facility was designed and installed. A substantially longer combustor was fabricated. Although not in the project plan or cost plan, an entire steam turbine-electric power generating plant was designed and the appropriate new and used equipment for continuous operation was specified. Insufficient funds and the lack of a customer for any electric power that the test facility could have generated prevented the installation of the power generating equipment needed for continuous operation. All other task 5 project measures were met and exceeded. 107 days of testing in task 5, which exceeded the 63 days (about 500 hours) in the test plan, were implemented. Compared to the first generation 20 MMBtu/hr combustor in Williamsport, the 2nd generation combustor has a much higher combustion efficiency, the retention of slag inside the combustor doubled to about 75% of the coal ash, and the ash carryover into the boiler, a major problem in the Williamsport combustor was essentially eliminated. In addition, the project goals for coal-fired emissions were exceeded in task 5. SO{sub 2} was reduced by 80% to 0.2 lb/MMBtu in a combination of reagent injection in the combustion and post-combustion zones. NO{sub x} was reduced by 93% to 0.07 lb/MMBtu in a combination of staged combustion in the combustor and post-combustion reagent injection. A baghouse was installed that was rated to 0.03 lb/MMBtu stack particle emissions. The initial particle emission test by EPA Method 5 indicated substantially higher emissions far beyond that indicated by the clear emission plume. These emissions were attributed to steel particles released by wall corrosion in the baghouse, correction of which had no effect of emissions.

CO2 SEQUESTRATION POTENTIAL OF TEXAS LOW-RANK COALS  

Science Conference Proceedings (OSTI)

The objectives of this project are to evaluate the feasibility of carbon dioxide (CO{sub 2}) sequestration in Texas low-rank coals and to determine the potential for enhanced coalbed methane (CBM) recovery as an added benefit of sequestration. The main tasks for this reporting period were to correlate well logs and refine coal property maps, evaluate methane content and gas composition of Wilcox Group coals, and initiate discussions concerning collection of additional, essential data with Anadarko. To assess the volume of CO{sub 2} that may be sequestered and volume of methane that can be produced in the vicinity of the proposed Sam Seymour sequestration site, we used approximately 200 additional wells logs from Anadarko Petroleum Corp. to correlate and map coal properties of the 3 coal-bearing intervals of Wilcox group. Among the maps we are making are maps of the number of coal beds, number of coal beds greater than 5 ft thick, and cumulative coal thickness for each coal interval. This stratigraphic analysis validates the presence of abundant coal for CO{sub 2} sequestration in the Wilcox Group in the vicinity of Sam Seymour power plant. A typical wellbore in this region may penetrate 20 to 40 coal beds with cumulative coal thickness between 80 and 110 ft. Gas desorption analyses of approximately 75 coal samples from the 3 Wilcox coal intervals indicate that average methane content of Wilcox coals in this area ranges between 216 and 276 scf/t, basinward of the freshwater boundary indicated on a regional hydrologic map. Vitrinite reflectance data indicate that Wilcox coals are thermally immature for gas generation in this area. Minor amounts of biogenic gas may be present, basinward of the freshwater line, but we infer that most of the Wilcox coalbed gas in the deep coal beds is migrated thermogenic gas. Analysis based on limited data suggest that sites for CO{sub 2} sequestration and enhanced coalbed gas recovery should be located basinward of the Wilcox freshwater contour, where methane content is high and the freshwater aquifer can be avoided.

Determination of Coal Permeability Using Pressure Transient Methods  

SciTech Connect

Coalbed methane is a significant natural resource in the Appalachian region. It is believed that coalbed methane production can be enhanced by injection of carbon dioxide into coalbeds. However, the influence of carbon dioxide injection on coal permeability is not yet well understood. Competitive sorption of carbon dioxide and methane gases onto coal is a known process. Laboratory experiments and limited field experience indicate that coal will swell during sorption of a gas and shrink during desorption of a gas. The swelling and shrinkage may change the permeability of the coal. In this study, the permeability of coal was determined by using carbon dioxide as the flowing fluid. Coal samples with different dimensions were prepared for laboratory permeability tests. Carbon dioxide was injected into the coal and the permeability was determined by using pressure transient methods. The confining pressure was variedto cover a wide range of depths. The permeability was also determined as a function of exposure time of carbon dioxide while the confining stress was kept constant. CT scans were taken before and after the introduction of carbon dioxide. Results show that the porosity and permeability of the coal matrix was very low. The paper presents experimental data and theoretical aspects of the flow of carbon dioxide through a coal sample during pressure transient tests. The suitability of the pressure transient methods for determining permeability of coal during carbon dioxide injection is discussed in the paper.

Outlook and challenges to coal in Asia: 1994--2015  

SciTech Connect

The two key threats to coal`s long term dominance in Asia are: (1) its uneven distribution of reserves and lack of adequate rail transportation infrastructure, and (2) growing environmental concerns about coal-related pollution. Even with increased attention to emissions control for coal, continued growth in coal consumption is expected to result in further deterioration of the environment in Asia for another one to two decades. China will remain the largest polluter in Asia, but it`s believed it will become Asia`s largest user of emissions control technology by 2015. The authors have subjectively weighed the above constraints to increased coal use in preparing the projections of the future role of coal in the Asian region. This paper shows past trends in coal production and consumption, plus projections of coal production, consumption and trade over the 1994--2015 period. The projections in this paper are useful as a general indicator of long term patterns in Asia. However, there are too many uncertainties about economic growth rates and energy and environmental policies to suggest that the projections will be accurate for every economy. This paper concludes with the preliminary results of research under way, which suggests that increasing economic wealth in China is the most important factor in solving China`s coal-related pollution problems.

Most of the major enviromental pollutants from coals originate as impurities in the coal structure. These include various organic compounds, minerals, and trace elements that are released into the air and water when coal is mined, processed and utilized. The use of coal preparation to produce cleaner burning fuels involves an environmental compromise, wherein reduced emissions and solid wastes from coal burning sources are achieved at the expense of greater environmental degradation from coal cleaning wastes.

The release of iron during coal combustion. Milestone report  

Science Conference Proceedings (OSTI)

Iron plays an important role in the formation of both fly ash and deposits in many pulverized-coal-fired boilers. Several authors indicate that iron content is a significant indicator of the slagging propensity of a majority of US bituminous coals, in particular eastern bituminous coals. The pyritic iron content of these coals is shown to be a particularly relevant consideration. A series of investigations of iron release during combustion is reported for a suite of coals ranging in rank from lignite to low-volatile bituminous coal under combustion conditions ranging from oxidizing to inert. Experimental measurements are described in which, under selected conditions, major fractions of the iron in the coal are released within a 25 ms period immediately following coal devolatilization. Mechanistic interpretation of the data suggest that the iron is released as a consequence of oxygen attack on porous pyrrhotite particles. Experimental testing of the proposed mechanism reveals that the release is dependent on the presence of both pyrite in the raw coal and oxygen in the gas phase, that slow preoxidation (weathering) of the pyrite significantly inhibits the iron release, and that iron loss increases as oxygen penetration of the particle increases. Each observation is consistent with the postulated mechanism.

THE DEVELOPMENT OF COAL-BASED TECHNOLOGIES FOR DEPARTMENT OF DEFENSE FACILITIES  

Science Conference Proceedings (OSTI)

The third phase of a three-phase project investigating the development of coal-based technologies for US Department of Defense (DOD) facilities was completed. The objectives of the project were to: decrease DOD's dependence on foreign oil and increase its use of coal; promote public and private sector deployment of technologies for utilizing coal-based fuels in oil-designed combustion equipment; and provide a continuing environment for research and development of coal-based fuel technologies for small-scale applications at a time when market conditions in the US are not favorable for the introduction of coal-fired equipment in the commercial and industrial capacity ranges. The Phase III activities were focused on evaluating deeply-cleaned coals as fuels for industrial boilers and investigating emissions control strategies for providing ultra-low emissions when firing coal-based fuels. This was addressed by performing coal beneficiation and preparation studies, and bench- to demonstration-scale emissions reduction studies. In addition, economic studies were conducted focused on determining cost and market penetration, selection of incentives, and regional economic impacts of coal-based technologies.

Development of an Ultra-fine Coal Dewatering Technology and an Integrated Flotation-Dewatering System for Coal Preparation Plants  

SciTech Connect

The project proposal was approved for only the phase I period. The goal for this Phase I project was to develop an industrial model that can perform continuous and efficient dewatering of fine coal slurries of the previous flotation process to fine coal cake of {approx}15% water content from 50-70%. The feasibility of this model should be demonstrated experimentally using a lab scale setup. The Phase I project was originally for one year, from May 2005 to May 2006. With DOE approval, the project was extended to Dec. 2006 without additional cost from DOE to accomplish the work. Water has been used in mining for a number of purposes such as a carrier, washing liquid, dust-catching media, fire-retardation media, temperature-control media, and solvent. When coal is cleaned in wet-processing circuits, waste streams containing water, fine coal, and noncombustible particles (ash-forming minerals) are produced. In many coal preparation plants, the fine waste stream is fed into a series of selection processes where fine coal particles are recovered from the mixture to form diluted coal fine slurries. A dewatering process is then needed to reduce the water content to about 15%-20% so that the product is marketable. However, in the dewatering process currently used in coal preparation plants, coal fines smaller than 45 micrometers are lost, and in many other plants, coal fines up to 100 micrometers are also wasted. These not-recovered coal fines are mixed with water and mineral particles of the similar particle size range and discharged to impoundment. The wasted water from coal preparation plants containing unrecoverable coal fine and mineral particles are called tailings. With time the amount of wastewater accumulates occupying vast land space while it appears as threat to the environment. This project developed a special extruder and demonstrated its application in solid-liquid separation of coal slurry, tailings containing coal fines mostly less than 50 micron. The extruder is special because all of its auger surface and the internal barrier surface are covered with the membranes allowing water to drain and solid particles retained. It is believed that there are four mechanisms working together in the dewatering process. They are hydrophilic diffusion flow, pressure flow, agitation and air purging. Hydrophilic diffusion flow is effective with hydrophilic membrane. Pressure flow is due to the difference of hydraulic pressure between the two sides of the membrane. Agitation is provided by the rotation of the auger. Purging is achieved with the air blow from the near bottom of the extruder, which is in vertical direction.

Alternative and innovative transport modes for moving US steam-coal exports to the Asian Pacific Basin  

Science Conference Proceedings (OSTI)

The United States is well positioned to play an expanding role in meeting the energy demands of the Asian Pacific Basin (APB). US coal reserves, among the world's largest, contain vast amounts of surface-mineable coal in the West in addition to significant volumes in the Midwest and East. However, high inland-transportation costs and the relatively low calorific value of some Western coals have recently resulted in delivered prices exceeding those of the world market -- maintaining the United States as a marginal supplier in a market that now receives one-third of worldwide steam-coal exports. This study describes alternatives that might reduce these delivered costs, emphasizing transport modes for four regions and mentioning blending for a fifth: (1) subbituminous coals of the Powder River Basin (Wyoming and Montana), (2) bituminous coals of central Utah and Colorado, (3) bituminous and subbituminous coals of the Four Corners Region (where Utah, Colorado, New Mexico, and Arizona meet), (4) bituminous and subbituminous coals of Alaska, and (5) bituminous coals of the Illinois Basin (Illinois, Indiana, and western Kentucky). It investigates innovative rail and ocean transport modes, coal-slurry pipelines, coal blends, and unconventional transport modes like overland conveyors and intermodal containers. It compares delivered prices under various scenarios, combining different transportation alternatives. 142 refs., 28 figs., 38 tabs.

Understanding the China energy market: trends and opportunities 2006  

SciTech Connect

The report details the current and future state of the energy industry in China. It is intended for strategists and researchers seeking to identify market potential for their products and services in all sectors of the China energy industry. The report is in 4 Sections: Overview of China Energy Market; Market Analysis; Market Segments (including electricity and coal); and Breaking into theMmarket. China's economic trajectory has driven its expanding energy needs, and it is now the world's second largest energy consumer behind the United States. China's energy sector has enormous potential, especially the coal, petroleum and natural gas industries, yet China is currently a net importer of oil, and imports are expected to increase to more than 900 million barrels in 2006, against a total demand of 1.993 billion barrels per year. China is looking to expand its production of coal, natural gas, and renewable energy sources such as nuclear, solar and hydroelectric power to meet the enormous appetite for energy spawned by its massive industrial complex and consumer sectors. It is estimated that in 2020, China will need 2.8 billion tons of coal and 600 million tons of crude oil, two and a half times more than in 2000.

STUDY OF SOLVENT AND CATALYST INTERACTIONS IN DIRECT COAL LIQUEFACTION  

SciTech Connect

Major objectives of the present project are to develop a better understanding of the roles of the catalyst and the liquefaction solvent in the coal liquefaction process. An open question concerning the role of the catalyst is whether intimate contact between the catalyst and the coal particles is important or required. To answer this question, it had been planned to coat an active catalyst with a porous silica coating which was found to retain catalyst activity while preventing actual contact between catalyst and coal. Consultation with people in DuPont who coat catalysts for increasing abrasion resistance have indicated that only portions of the catalyst are coated by their process (spray drying) and that sections of uncoated catalyst remain. For that reason, it was decided to suspend the catalyst in a basket separated from the coal in the reactor. The basket walls were to be permeable to the liquefaction solvent but not to the coal particles. Several such baskets were constructed of stainless steel with holes which would not permit passage of coal particles larger than 30 mesh. Liquefactions run with the coal of greater than 30 mesh size gave normal conversion of coal to liquid in the absence of catalyst in the basket, but substantially increased conversion when Ni/Mo on alumina catalyst was in the basket. While this result is interesting and suggestive of some kind of mass transfer of soluble material occurring between the catalyst and the coal, it does not eliminate the possibility of breakdown of the coal particle into particle sizes permeable to the basket. Indeed, a small amount of fine coal has been found inside the basket. To determine whether fine coal from breakdown of the coal particles is responsible for the conversion, a new basket is being prepared with 0.5{micro}m pore size.

Low rank coal upgrading in a flow of hot water  

Science Conference Proceedings (OSTI)

Simultaneous hydrothermal degradation and extraction at around 350{sup o}C using flowing solvent as a reaction/extraction medium were proposed for upgrading brown coal, more specifically, for converting brown coal into several fractions having different molecular weight and chemical structure under mild conditions. When an Australian brown coal, Loy Yang coal, was treated by water at 350{sup o}C under 18 MPa, the coal was separated into four fractions: gaseous product by 8% yield, water-soluble extract at room temperature (soluble) by 23% yield, extract precipitates as solid at room temperature (deposit) by 23% yield, and residual coal (upgraded coal) by 46% yield on daf basis. The separation was found to be realized by in situ extraction of low-molecular-weight substances released from coal macromolecular structure and/or those generated by hydrothermal decomposition reactions at 350{sup o}C. The solid products obtained, deposit and upgraded coal, were characterized in detail to examine the possibility of their effective utilization as solid fuel and chemical feed stock. The upgraded coal showed higher heating value and higher gasification reactivity than the parent coal, indicating that the upgraded coal can be a better solid fuel than the parent coal. The solid extract, deposit, was found to show thermoplasticity at less than 200{sup o}C, suggesting the possibility of utilizing the deposit as a raw material of high performance carbon materials. Several variables affecting the performance of the proposed method are also examined in detail in this paper. 12 refs., 8 figs., 3 tabs.

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.

The Clean Coal Technology Program: Lessons learned  

Science Conference Proceedings (OSTI)

The Clean Coal Technology (CCT) Program is a unique partnership between the federal government and industry that has as its primary goal the successful introduction of new clean coal utilization technologies into the energy marketplace. Clean coal technologies being demonstrated under the CCT Program are establishing a technology base that will enable the nation to meet more stringent energy and environmental goals. Most of the, demonstrations are being conducted at commercial scale, in actual user environments, and under circumstances typical of commercial operations. These features allow the potential of the technologies to be evaluated in their intended commercial applications. Each application addresses one of the following four market sectors: advanced electric power generation; environmental control devices; coal processing for clean fuels; and industrial applications. The purpose of this report is fourfold: Explain the CCT program as a model for successful joint government industry partnership for selecting and demonstrating technologies that have promise for adaptation to the energy marketplace; set forth the process by which the process has been implemented and the changes that have been made to improve that process; outline efforts employed to inform potential users and other interested parties about the technologies being developed; and examine some of the questions which must be considered in determining if the CCT Program model can be applied to other programs.

GEOLOGIC SCREENING CRITERIA FOR SEQUESTRATION OF CO2 IN COAL: QUANTIFYING POTENTIAL OF THE BLACK WARRIOR COALBED METHANE FAIRWAY, ALABAMA  

SciTech Connect

Sequestration of CO{sub 2} in coal has potential benefits for reducing greenhouse gas emissions from the highly industrialized Carboniferous coal basins of North America and Europe and for enhancing coalbed methane recovery. Hence, enhanced coalbed methane recovery operations provide a basis for a market-based environmental solution in which the cost of sequestration is offset by the production and sale of natural gas. The Black Warrior foreland basin of west-central Alabama contains the only mature coalbed methane production fairway in eastern North America, and data from this basin provide an excellent basis for quantifying the carbon sequestration potential of coal and for identifying the geologic screening criteria required to select sites for the demonstration and commercialization of carbon sequestration technology. Coalbed methane reservoirs in the upper Pottsville Formation of the Black Warrior basin are extremely heterogeneous, and this heterogeneity must be considered to screen areas for the application of CO{sub 2} sequestration and enhanced coalbed methane recovery technology. Major screening factors include stratigraphy, geologic structure, geothermics, hydrogeology, coal quality, sorption capacity, technology, and infrastructure. Applying the screening model to the Black Warrior basin indicates that geologic structure, water chemistry, and the distribution of coal mines and reserves are the principal determinants of where CO{sub 2} can be sequestered. By comparison, coal thickness, temperature-pressure conditions, and coal quality are the key determinants of sequestration capacity and unswept coalbed methane resources. Results of this investigation indicate that the potential for CO{sub 2} sequestration and enhanced coalbed methane recovery in the Black Warrior basin is substantial and can result in significant reduction of greenhouse gas emissions while increasing natural gas reserves. Coal-fired power plants serving the Black Warrior basin in Alabama emit approximately 31 MMst (2.4 Tcf) of CO{sub 2} annually. The total sequestration capacity of the Black Warrior coalbed methane fairway at 350 psi is about 189 MMst (14.9 Tcf), which is equivalent to 6.1 years of greenhouse gas emissions from the coal-fired power plants. Applying the geologic screening model indicates that significant parts of the coalbed methane fairway are not accessible because of fault zones, coal mines, coal reserves, and formation water with TDS content less than 3,000 mg/L. Excluding these areas leaves a sequestration potential of 60 MMst (4.7 Tcf), which is equivalent to 1.9 years of emissions. Therefore, if about10 percent of the flue gas stream from nearby power plants is dedicated to enhanced coalbed methane recovery, a meaningful reduction of CO{sub 2} emissions can be realized for nearly two decades. If the fresh-water restriction were removed for the purposes of CO{sub 2} sequestration, an additional 10 MMst (0.9 Tcf) of CO{sub 2} could feasibly be sequestered. The amount of unswept coalbed methane in the fairway is estimated to be 1.49 Tcf at a pressure of 50 psi. Applying the screening model results in an accessible unswept gas resource of 0.44 Tcf. Removal of the fresh-water restriction would elevate this number to 0.57 Tcf. If a recovery factor of 80 percent can be realized, then enhanced recovery activities can result in an 18 percent expansion of coalbed methane reserves in the Black Warrior basin.

Structural response of coal to drying and pentane sorption  

Science Conference Proceedings (OSTI)

Experiments probed the response of coal toward drying and subsequent sorption and desorption of pentane. The change in porosity due to drying was calculated from the difference between the expected volume change associated with H{sub 2}O loss and the observed volume change. For low rank coals, a slight increase in porosity was found. For coals {gt}85 wt % carbon a slight decrease occurred. Pentane sorption experiments were conducted for up to 365 days using coals dried at room temperature. A significant amount of pentane could not be removed upon evacuation for 100 min at room temperature, conditions suitable for removal of this sorbate from interconnected macro-, meso-, and micropores. However, much of this pentane could be removed upon extended evacuation. Negligible swelling of coal accompanies pentane sorption despite its considerable presence indicating that pentane adsorbs on surfaces of open pore space. The quantity of 'slow reversible' pentane was compared to the quantity of CO{sub 2} determined from BET experiments. The degree of connectivity of the pore system of coal was estimated from the ratio of 'slow reversible' pentane surface area to CO{sub 2} BET surface area. A ratio of 1.0 indicates a completely unconnected pore network, while a ratio of 0.0 indicates a completely interconnected pore network. The range of this ratio was 0.46-0.73 for coal dried under high vacuum at room temperature. These findings indicate that interconnection among pores is incomplete for these coals. For most coals, drying at 150{sup o}C affects the quantity of slow reversible pentane, and this is associated with alteration in the connectivity of the network pore structure of coal. 52 refs., 7 figs., 9 tabs.

State coal profiles, January 1994  

SciTech Connect

The purpose of State Coal Profiles is to provide basic information about the deposits, production, and use of coal in each of the 27 States with coal production in 1992. Although considerable information on coal has been published on a national level, there is a lack of a uniform overview for the individual States. This report is intended to help fill that gap and also to serve as a framework for more detailed studies. While focusing on coal output, State Coal Profiles shows that the coal-producing States are major users of coal, together accounting for about three-fourths of total US coal consumption in 1992. Each coal-producing State is profiled with a description of its coal deposits and a discussion of the development of its coal industry. Estimates of coal reserves in 1992 are categorized by mining method and sulfur content. Trends, patterns, and other information concerning production, number of mines, miners, productivity, mine price of coal, disposition, and consumption of coal are detailed in statistical tables for selected years from 1980 through 1992. In addition, coal`s contribution to the State`s estimated total energy consumption is given for 1991, the latest year for which data are available. A US summary of all data is provided for comparing individual States with the Nation as a whole. Sources of information are given at the end of the tables.

Coal resource estimation in the Bayir field, Yatagan-Mugla, SW Turkey  

SciTech Connect

This study focuses on some coal properties and calculation of coal resources with two classical (isopach and polygon) methods in the Bayir field, Yatagan-Mugla, which is located in southwestern Anatolia. This field has not been mined because it is still in the exploration stage. A productive coal seam of Early (?)-Middle Miocene age has a mineable coal thickness of 1.25 m to 18.01 m. Proximate analysis results indicated that this coal seam contains high moisture, ash, volatile matter, total sulphur content, and net calorific values. The weighted average mineable coal thickness calculated from the isopachs is 7.52 m and 7.82 m from polygonal methods. The in situ tonnages with isopach and polygonal methods were calculated to be 122.8 Mt and 130 Mt, respectively. The average value of the two methods shows 126.4 Mt in situ coal tonnages. Total amount of the in situ mineable coal resources is 77.7 Mt, which indicates an important coal potential in the Bayir field. The overburden thickness ranges from 72 m to 493 m in the Bayir field, averaging 257 m, indicating a deep coal mine. The overburden ratio averages 37 m{sup 3}/ton, indicating an underground coal mine to feed a power plant in near future.

A combined physical/microbial process for coal beneficiation  

SciTech Connect

A combined physical/microbial process for the removal of pyritic sulfur from coal was demonstrated in a 200 L aerated trough slurry reactor. The reactor was divided into six sections, each of which acted as both a physical separator and a bioreactor. Settled solids from sections 2 through 6 were recycled to section 1 which acted as a rougher. The objective was physical removal of the larger pyritic inclusions, which would take many days to biodegrade, and biodegradation of the micropyrite, which is difficult to remove physically. The process was operated continuously for 8 months, treating two Illinois No. 6 coals (4 months each). Reduction of 90% in-pyritic sulfur with 90% energy recovery and 35% ash removal was obtained for a low pyrite Monterey coal at a 5 day coal retention time and 20% (w/w) slurry concentration. Increased coal loading reduced performance apparently due to losses of sulfur oxidizing bacteria. A low pyrite Consol coal gave 63--77% pyrite reduction with 23--30% ash removal and 77--90% heating value recovery. Product coal pyritic sulfur analysis indicated no differences between treatments of Consol coal. This suggests that the coal residence time could be further reduced and the slurry concentration increased in future work.

The recycling of the coal fly ash in glass production  

Science Conference Proceedings (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.

Summary of the APEC coal trade and investment liberalization and facilitation workshop: Facilitating trade and investment in Indonesia`s coal energy sector  

SciTech Connect

The Workshop brought together experts from APEC economies to discuss important issues related to coal development, trade and consumption in the APEC region, with a focus on Indonesia. Papers ranged from broad regional coal-related issues to specific policy and contract terms. The host, Indonesia, was selected as the focus of the workshop because it: (a) has APEC`s fastest growing electricity sector, (b) is in the process of switching from oil based electricity generation to coal and natural gas-based generation, (c) is among the fastest growing coal exporters in APEC, and (d) has a contract system for coal development that has been widely accepted by foreign investors. In addition, Indonesia is in the process of revising its coal policies, and might benefit from the timely discussions in this workshop. The papers presented in the workshop spanned the coal chain from coal resources and reserves, conversion technologies, economics and markets, legal and policy issues, to community and cultural concerns. Participants represented government, industry and academic interests, and provided perspectives of coal and technology suppliers, consumers, energy policy makers and legal experts.

Create a Consortium and Develop Premium Carbon Products from Coal  

DOE Green Energy (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.

Alaska coal gasification feasibility studies - Healy coal-to-liquids plant  

SciTech Connect

The Alaska Coal Gasification Feasibility Study entailed a two-phase analysis of the prospects for greater use of Alaska's abundant coal resources in industrial applications. Phase 1, Beluga Coal Gasification Feasibility Study (Report DOE/NETL 2006/1248) assessed the feasibility of using gasification technology to convert the Agrium fertilizer plant in Nikiski, Alaska, from natural gas to coal feedstock. The Phase 1 analysis evaluated coals from the Beluga field near Anchorage and from the Usibelli Coal Mine near Healy, both of which are low in sulfur and high in moisture. This study expands the results of Phase 1 by evaluating a similar sized gasification facility at the Usibelli Coal mine to supply Fischer-Tropsch (F-T) liquids to central Alaska. The plant considered in this study is small (14,640 barrels per day, bbl/d) compared to the recommended commercial size of 50,000 bbl/d for coal-to-liquid plants. The coal supply requirements for the Phase 1 analysis, four million tons per year, were assumed for the Phase 2 analysis to match the probable capacity of the Usibelli mining operations. Alaska refineries are of sufficient size to use all of the product, eliminating the need for F-T exports out of the state. The plant could produce marketable by-products such as sulfur as well as electric power. Slag would be used as backfill at the mine site and CO{sub 2} could be vented, captured or used for enhanced coalbed methane recovery. The unexpected curtailment of oil production from Prudhoe Bay in August 2006 highlighted the dependency of Alaskan refineries (with the exception of the Tesoro facility in Nikiski) on Alaska North Slope (ANS) crude. If the flow of oil from the North Slope declines, these refineries may not be able to meet the in-state needs for diesel, gasoline, and jet fuel. Additional reliable sources of essential fuel products would be beneficial. 36 refs., 14 figs., 29 tabs., 3 apps.

SURFACE-MODIFIED COALS FOR ENHANCED CATALYST DISPERSION AND LIQUEFACTION  

SciTech Connect

This is the final report of the Department of Energy Sponsored project DE-FGF22-95PC95229 entitled, surface modified coals for enhanced catalyst dispersion and liquefaction. The aims of the study were to enhance catalyst loading and dispersion in coal for improved liquefaction by preadsorption of surfactants and catalysts on the coal and to train and educate minority scientists in catalysts and separation science. Illinois No. 6 Coal (DEC-24) was selected for the study. The surfactants investigated included dodecyl dimethyl ethyl ammonium bromide (DDAB), a cationic surfactant, sodium dodecyl sulfate, an anionic surfactant, and Triton x-100, a neutral surfactant. Ammonium molybdate tetrahydrate was used as the molybdenum catalyst precursor. Zeta potential, BET, FTIR, AFM, UV-Vis and luminescence intensity measurements were undertaken to assess the surface properties and the liquefaction activities of the coal. The parent coal had a net negative surface charge over the pH range 2-12. However, in the presence of DDAB the negativity of the surface charge decreased. At higher concentrations of DDAB, a positive surface charge resulted. In contrast to the effect of DDAB, the zeta potential of the coal became more negative than the parent coal in the presence of SDS. Adsorption of Triton reduced the net negative charge density of the coal samples. The measured surface area of the coal surface was about 30 m{sup 2}/g compared to 77m{sup 2}/g after being washed with deionized water. Addition of the surfactants decreased the surface area of the samples. Adsorption of the molybdenum catalyst increased the surface area of the coal sample. The adsorption of molybdenum on the coal was significantly promoted by preadsorption of DDAB and SDS. Molybdenum adsorption showed that, over a wide range of concentrations and pH values, the DDAB treated coal adsorbed a higher amount of molybdenum than the samples treated with SDS. The infrared spectroscopy (FTIR) and the atomic force microscopy (AFM) also provided evidence that confirmed the adsorption of the surfactants onto the coal surface. The luminescence measurements showed that the coal and solid surfactants luminescence weakly. No statistically significant influence was observed that resulted from the action of the surfactants or surfactant-molybdenum catalyst. Interestingly, the liquefaction results produced data that indicated the use of surfactants did not significantly improve the liquefaction activity of the coal as had initially been hypothesized. The UV-adsorption tests provided evidence that suggest that this may have been due to oversaturation. Detailed discussions of the results and recommendations for future work are provided.
