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.

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

SciTech Connect

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

Annual prospects for world coal trade 1985: with projections to 1995  

SciTech Connect

The Energy Information Administration (EIA) projects US and world coal trade to 1995, and annually updates the projections in the Annual Energy Outlook. The current projections assume that world coal trade will expand between now and 1995 in response to increasing demand for steam coal. US coal exports rose rapidly between 1979 and 1981, from 66 million short tons to 113 million short tons, partly as a result of labor problems in Poland and Australia. After declining slightly to 106 million short tons in 1982, US coal exports decreased sharply to 78 million short tons in 1983 due to increased supplies of Polish coal in Western Europe and Australian coal in Asia. Moreover, the continued strength of the US dollar made US coal more expensive overseas. US coal exports rose slightly in 1984, to 81 million short tons. Exports of US coal in 1985 are projected to be approximately 71 million short tons. As a high-cost supplier of export coal, the United States has been the ''swing supplier'' because of its ability to ship large amounts of coal on short notice. The United States is likely to maintain a significant share of the world market as a reliable supplier of high-quality coal. EIA projections of US coal exports and world coal trade for 1990 and 1995 are provided in a mid-demand (or base) case as well as in two other cases, a low-demand case and a high-demand case, that reflect uncertainties in the projections. EIA estimates of import coal demand for 1990 and 1995 were developed using key energy supply and demand information for the principal coal-importing countries in Western Europe and Asia, and evaluating that information in the context of estimated trends in economic growth and energy use. 3 figs., 26 tabs.

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.

The 2006-2011 world outlook for coal mining  

SciTech Connect

This study covers the world outlook for coal mining across more than 200 countries. For each year reported, estimates are given for the latent demand, or potential industry earnings (P.I.E.), for the country in question (in millions of U.S. dollars), the percent share the country is of the region and of the globe. These comparative benchmarks allow the reader to quickly gauge a country against others. Using econometric models which project fundamental economic dynamics within each country and across countries, latent demand estimates are created. This report does not discuss the specific players in the market serving the latent demand, nor specific details at the product level. The study, therefore, is strategic in nature, taking an aggregate and long-run view, irrespective of the players or products involved. This study does not report actual sales data. This study gives, however, estimates for the worldwide latent demand, or the P.I.E., for coal mining. It also shows how the P.I.E. is divided across the world's regional and national markets. For each country, estimates are given of how the P.I.E. grows over time (positive or negative growth).

Dominant Middle East oil reserves critically important to world supply  

SciTech Connect

This paper reports that the location production, and transportation of the 60 million bbl of oil consumed in the world each day is of vital importance to relations between nations, as well as to their economic wellbeing. Oil has frequently been a decisive factor in the determination of foreign policy. The war in the Persian Gulf, while a dramatic example of the critical importance of oil, is just the latest of a long line of oil-influenced diplomatic/military incidents, which may be expected to continue. Assuming that the world's remaining oil was evenly distributed and demand did not grow, if exploration and development proceeded as efficiently as they have in the U.S., world oil production could be sustained at around current levels to about the middle of the next century. It then would begin a long decline in response to a depleting resource base. However, the world's remaining oil is very unevenly distributed. It is located primarily in the Eastern Hemisphere, mostly in the Persian Gulf, and much is controlled by the Organization of Petroleum Exporting Countries. Scientific resource assessments indicate that about half of the world's remaining conventionally recoverable crude oil resource occurs in the Persian Gulf area. In terms of proved reserves (known recoverable oil), the Persian Gulf portion increase to almost two-thirds.

EIA cites importance of key world shipping routes  

SciTech Connect

A disruption of crude oil or products shipments through any of six world chokepoints would cause a spike in oil prices, the US Energy Information Administration (EIA) warns. The strategic importance of each major shipping lane varies because of differing oil volumes and access to other transportation routes. But nearly half of the 66 million b/d of oil consumed worldwide flows through one or more of these key tanker routes, involving: 14 million b/d through the Strait of Hormuz from the Persian Gulf to the Gulf of Oman and Arabian Sea; 7 million b/d through the Strait of Malacca from the northern Indian Ocean into the South China Sea and Pacific Ocean; 1.6 million b/d through the Bosporus from the Black Sea to the Mediterranean Sea; 900,000 b/d through the Suez Canal from the Red Sea to the Mediterranean Sea; 600,000 b/d through Rotterdam Harbor from the North Sea to Dutch and German refineries on or near the Rhine River; and 500,000 b/d through the Panama Canal from the Pacific Ocean to the Caribbean Sea. In today's highly interdependent oil markets, the mere perception of less secure oil supplies is enough to boost oil prices, EIA said. Growing oil and product tanker traffic is increasing the likelihood of supply disruptions through oil arteries because of bad weather, tanker collisions, or acts of piracy, terrorism, or war. What's more, the increasing age of the world tanker fleet and dependability of navigational equipment could increase chances of accidents and, therefore, oil supply disruptions.

Coal - prices tumble as the glut continues  

SciTech Connect

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

China's new oil import status underpins world's most dynamic petroleum scene  

SciTech Connect

China is poised to become a net importer of oil in 1994--95. That sets the stage for China importing more than 1 million b/d of crude oil and refined products on a net basis by the turn of the century. That development underpins a bigger story -- arguably the biggest story on the petroleum scene today. The turnabout that is seeing the world's fifth biggest oil producer go from significant oil exporter in recent years to major oil importer by the turn of the century points to several other truisms in the petroleum industry: That an oil demand surge in the Asia-Pacific region led by China will fuel overall world oil demand growth for years to come; that a refining and petrochemical boom in a country that accounts for about one fifth of the world's population has dramatic implications for those two industries; that privatization has gathered so much momentum in the global petroleum industry that even Communist China has embraced some form of it; that China's domestic crude supply shortfall is creating unprecedented opportunities for foreign upstream investors in one of the world's most prospective yet underexplored and underexploited regions; and that the same new openness that is distinguishing China's petroleum industry today is turning some of its state owned companies into major competitors to be reckoned with on the international scene, upstream and downstream. The paper discusses China's oil export/import balance, supply/demand outlook, policy changes, and new regulations governing export of crude oil and products.

Appalachia: the land of coal  

SciTech Connect

The Appalachian region of the United States is an area known worldwide for its long history as a source of coal. If any area of the Unted States is to gain from the projected growth of the coal industry, both domestic and international, it would surely be the coal mining areas of this region, including its biggest coal producing states - Pennsylvania, West Virginia, Kentucky and Ohio. An important facet of the region's coal industry is not only the presence of the giant coal companies but also the small, independent operator. These men are owner-operators and every dollar spent for their operations must bring a return. There is no room for error. WORLD COAL editors have recently traveled to areas in Appalachia and visited mines that are run by these independent operators. One such area was Harlan County, Kentucky. Virtually all mining done in Harlan is underground. Shaft mines are uncommon; most operations have access to exposed seams in the hillsides. Most of the small operations in this region use room and pillar mining and productivity is quite good. It is imperative that the transportation infrastructure be improved so that the expected increased movement of coal out of the region be handled efficiently. Potential domestic consumers of coal from Appalachia are numerous. New England, New York, the mid-Atlantic states, and the South are all looking to this nearby region to help reduce their dependence on oil. Other countries also are looking to the area.

Section 5 - Coal  

Science Journals Connector (OSTI)

Coal has the longest history of use among the fossil fuels, with use as a fuel dating to 3000 BC in China and Wales. Marco Polo’s “Description of the World” (1298) comments on many novel customs and practices of China, including the use of “stones that burn like logs” (coal). By the thirteenth century the mining of coal was widespread in England in regions such as Durham, Nottinghamshire, Derbyshire, Staffordshire, and North and South Wales. By the early seventeenth century nearly half of England’s maritime trade consisted of coal exports. Coal was the fuel that launched the Industrial Revolution in Europe and then the United States. By the late 1890s, the U.S. assumed the lead in world coal production. Britain now ranked second, after having been the world leader since the beginnings of the formal industry in the 1500s. Germany was third, an indication of its growing industrial power relative to continental rival France. Coal’s leading role in energy use peaked in the early twentieth century, after which it was supplanted by oil and natural gas. By the late twentieth century China’s rapid economic expansion, surging demand for electricity, and prodigious coal resources combined to propel it to become the world leader in production. Continuous improvements in coal mining technology have produced lower costs, improved safety, and greater labor productivity. John Buddle introduced the first air pump to ventilate coal mines (1803), followed shortly by the miner’s safety lamps that were developed independently by Sir Humphry Davy, William Clanny, and George Stephenson (1813-1816). Coal mining underwent a rapid transition in the 1880s to mechanical coal cutting in mines in the United Kingdom, the United States, and Russia. The St. Joseph Lead Company of Missouri (1900) invented the first underground mine roof bolts that became a key safety feature in underground coal mines. The first commercially successful bucket wheel excavator was used at the Luise Mine in Braunkohlemwerke, Germany (1925), followed by the first successful continuous miners in U.S. underground coal mining (1948). The first mechanized U.S. longwall mining system appeared in 1951, and was followed by the self-advancing hydraulic longwall support system that provided greater support for the roof of the mine. LeTourneau Technologies, Inc. of Texas manufactured the largest rubber tired front-end wheel loader in the world, the L-2350, which would play an important role in loading coal in Wyoming’s large surface mines (2005). Coal mining has always been a very hazardous occupation, and has produced some of history’s worst industrial disasters. The Courrières mine disaster, Europe's worst mining accident, caused the death of 1,099 miners in Northern France (1906). An explosion in a coal mine in Liaoning province in northeastern China killed more than 1,500 Chinese miners (1942), as did other major accidents in Ky?sh?, Japan (1914), Wankie, Rhodesia (1972), Wales (1913), Bihar, India (1965), and West Virginia, U.S. (1907), to name just a few. Legislation such as the Federal Coal Mine Health and Safety Act in the U.S. (1969) improved working conditions in many nations. The Great Smog of London (1952) occurred after an exceptionally cold winter forced homes and factories to burn large quantities of coal. A temperature inversion formed, trapping pollutants above the ground. More than 4,000 people died from respiratory ailments within the following week. The use of coal has been impacted by legislation to control the environmental impacts associated with its mining and combustion. The first known environmental regulation of coal dates to 1306 when King Edward II of England prohibited burning sea coal while Parliament was in session because of its offensive smoke. Sulfur dioxide from coal combustion was tied to acid rain in the 1960s, and carbon dioxide emissions became a concern beginning in the 1980s when climate change emerged as a critical environmental issue.

Coal Coal Fossil Energy Study Guide: Coal Coal is the most plentiful fuel in the fossil family. The United States has more coal reserves than any other country in the world. In fact, one-fourth of all known coal in the world is in the United States, with large deposits located in 38 states. The United States has almost as much energ y in coal that can be mined as the rest of the world has in oil that can be pumped from the ground. TYPES OF COAL Coal is a black rock made up of large amounts of carbon. Like all fossil fuels, coal can be burned to release energy.

Coal preparation: The essential clean coal technology  

SciTech Connect

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

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.

4 - Coal resources and reserves  

Science Journals Connector (OSTI)

Abstract: Coal resources still make up a significant proportion of the world’s energy supplies. Coal resources are estimated to be 860 billion tonnes. These resources are geographically well distributed and current production provides fuel for 29% of the world’s primary energy consumption. The classification of coal resources and reserves has been redefined in recent years, with the standards and codes of practice adopted by the principal coal-producing countries being equated on a global basis. Details of the principal classifications are given, together with their international equivalents. Reporting of resources and reserves plus methods of calculation are also given, together with recent assessments of global coal reserves.

Initiation of weak coal-dust explosions in long galleriesand the importance of the time dependence of the explosion pressure  

Science Journals Connector (OSTI)

Weak coal-dust explosions in galleries (large horizontal tubes) are defined in the paper asthe early stages of what may eventually become a self-sustaining, steady-state situation, if the scale is large enough. An initiating explosion producing a pressure rise of at least 12 kPa is needed to start an explosion from any additional dust that lies beyond the initiating zone; entrainment of this additional dust leads to the main explosion. In long galleries, initiating explosions in the range 16±2 kPa are mostly used. The early stages of the main explosion resemble explosions in which combustion of a very low concentration of coal-dust particles is taking place over a considerable volume at any given time, rather than explosions in which a flame, having a more or less definable front and rear, is propagating through a preformed explosive mixture. The explosions are described in terms of the general shape of the pressure changes occurring at a point near the outermost extent of the flame that is produced by the initiation explosion alone. The initial pressure rise is determined by the form of the initiating explosion and is followed by a roughly exponential pressure increase (from atmospheric pressure), whose time constant depends on the nature of the coal-dust, its dispersion, and the dimensions and characteristics of the gallery. The effects on the development of the explosion of the presence of short dust deposits, suppressive devices, and the ignition of predispersed clouds are briefly discussed. It is concluded that, in weak explosions, propagation results from dust being swept from the floor into the zone of combustion behind the flame front. However, as pressures increase to above, say, 100 kPa, other mechanisms become responsible and, perhaps, a pre-detonation regime sets in.

Investigations into coal coprocessing and coal liquefaction  

SciTech Connect

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.

Coal dust explosibility  

Science Journals Connector (OSTI)

This paper reports US Bureau of Mines (USBM) research on the explosibility of coal dusts. The purpose of this work is to improve safety in mining and other industries that process or use coal. Most of the tests were conducted in the USBM 20 litre laboratory explosibility chamber. The laboratory data show relatively good agreement with those from full-scale experimental mine tests. The parameters measured included minimum explosible concentrations, maximum explosion pressures, maximum rates of pressure rise, minimum oxygen concentrations, and amounts of limestone rock dust required to inert the coals. The effects of coal volatility and particle size were evaluated, and particle size was determined to be at least as important as volatility in determining the explosion hazard. For all coals tested, the finest sizes were the most hazardous. The coal dust explosibility data are compared to those of other hydrocarbons, such as polyethylene dust and methane gas, in an attempt to understand better the basics of coal combustion.

Some of the developing nations aim to earn foreign currency by exporting oil and/or gas and to increase the domestic consumption of coal to ensure a secure energy supply. Therefore, it is very important to promote effective coal utilization in these nations. Currently, these countries experience problems associated with coal use for household cooking and household industries. For household cooking, coal creates too much smoke and smells unpleasant. In addition, illegally obtained firewood is almost free in local agricultural regions. Coal is also used in household industries; however, simple stoker boilers are inefficient, since unburned coal particles tend to drop through screens during the combustion process. The bio-coal briquette, on the other hand, is an effective and efficient fuel, since it utilizes coal, which is to be used extensively in households and in small and medium-scale industry sectors in some coal-producing countries, as a primary fuel and bamboos (agricultural waste) as a secondary fuel. In addition, the use of bio-coal briquettes will greatly help reduce unburned coal content.

Coal science for the clean use of coal  

SciTech Connect

Coal will need to be retained as a major source of energy in the next century. It will need to be used more effectively and more cleanly. In order to achieve this, it is necessary to introduce new technology supported by a local community of science and technology. Only in this way can the full benefits of international advances in coal utilization be fully achieved. It is important that full advantage be taken of the advances that have been achieved in laboratory techniques and in the better understanding of fundamental coal science. This paper reviews available technologies in power generation, industrial process heat, coal combustion, coal gasification, and coal analytical procedures.

Chapter 3 - Coal-fired Power Plants  

Science Journals Connector (OSTI)

Abstract Coal provides around 40% of the world’s electricity, more than any other source. Most modern coal-fired power stations burn pulverized coal in a boiler to raise steam for a steam turbine. High efficiency is achieved by using supercritical boilers made of advanced alloys that produce high steam temperatures, and large, high-efficiency steam turbines. Alternative types of coal-fired power plants include fluidized bed boilers that can burn a variety of poor fuels, as well as coal gasifiers that allow coal to be turned into a combustible gas that can be burned in a gas turbine. Emissions from coal plants include sulfur dioxide, nitrogen oxide, and trace metals, all of which must be controlled. Capturing carbon dioxide from a coal plant is also under consideration. This can be achieved using post-combustion capture, a pre-combustion gasification process, or by burning coal in oxygen instead of air.

1 - Social and economic value of coal  

Science Journals Connector (OSTI)

Abstract: As the world’s leading source of electric power, coal is the continuing cornerstone of economic development, social progress, and a higher quality of life. Coal is powering the twenty-first century economic miracles rapidly unfolding in China and India, as reliability, affordability, and availability make coal the fuel of choice in the developing world. Demand modeling from both the International Energy Agency and US Energy Information Administration indicates that coal will provide the most amount of incremental energy over the next two decades. Looking forward, with the expanding implementation of clean coal technologies, the door to coal’s global leadership role will remain open as the world strives to meet the ever-rising demand for energy while reducing greenhouse gas emissions.

SNG Production from Coal: A Possible Solution to Energy Demand  

Science Journals Connector (OSTI)

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

Forecast of Advanced Technology for Coal Power Generation Towards the Year of 2050 in CO2 Reduction Model of Japan  

Science Journals Connector (OSTI)

Abstract In the fossil fuel, coal is enough to get easily because it has supply and price stability brought about its ubiquitously. Coal is used for power generation as the major fuel in the world. However it is true that control of global warming should be applied to coal power generations. Therefore, many people expect CO2 reduction by technical innovation such as efficiency improvement, Carbon dioxide Capture and Storage (CCS). In case of coal power plant are considered for improving efficiency. Some of them have already put into commercial operation but others are still under R&D stage. Especially, the technical development prospect of the power plant is very important for planning the energy strategy in the resource-importing country. Japan Coal Energy Center (JCOAL) constructed a program to forecast the share of advanced coal fired plants/natural gas power plants towards the year of 2050. Then, we simulated the future prediction about 2 cases (the Japanese scenario and the world scenario). The fuel price and the existence of CCS were considered in the forecast of the technical development of the thermal power generation. Especially in the Japanese scenario, we considered the CO2 reduction target which is 80% reduction in 1990. In the world scenario, coal price had almost no influence on the share of coal fired plant. However, when the gas price increased 1.5% or more, the share of coal fired plant increased. In that case, CO2 emissions increased because coal-fired plant increased. Compared with both cases, the amount of CO2 in 2050 without CCS case was 50% higher than that of with CCS case. In Japanese scenario, achievement of 80% CO2 reduction target is impossible without CCS. If CCS is introduced into all the new establishment coal fired plant, CO2 reduction target can be attained. In the Japanese scenario, the gas price more expensive than a coal price so that the amount of the coal fired plant does not decline. Since the reduction of the amount of CO2 will be needed in all over the world, introductory promotion and technical development of CCS are very important not only Japan but also all over the world.

Rationale for continuing R&D in direct coal conversion to produce high quality transportation fuels  

SciTech Connect

For the foreseeable future, liquid hydrocarbon fuels will play a significant role in the transportation sector of both the United States and the world. Factors favoring these fuels include convenience, high energy density, and the vast existing infrastructure for their production and use. At present the U.S. consumes about 26% of the world supply of petroleum, but this situation is expected to change because of declining domestic production and increasing competition for imports from countries with developing economies. A scenario and time frame are developed in which declining world resources will generate a shortfall in petroleum supply that can be allieviated in part by utilizing the abundant domestic coal resource base. One option is direct coal conversion to liquid transportation fuels. Continued R&D in coal conversion technology will results in improved technical readiness that can significantly reduce costs so that synfuels can compete economically in a time frame to address the shortfall.

CBM and CO2-ECBM related sorption processes in coal: A review  

Science Journals Connector (OSTI)

This article reviews the state of research on sorption of gases (CO2, CH4) and water on coal for primary recovery of coalbed methane (CBM), secondary recovery by an enhancement with carbon dioxide injection (CO2-ECBM), and for permanent storage of CO2 in coal seams. Especially in the last decade a large amount of data has been published characterizing coals from various coal basins world-wide for their gas sorption capacity. This research was either related to commercial CBM production or to the usage of coal seams as a permanent sink for anthropogenic CO2 emissions. Presently, producing methane from coal beds is an attractive option and operations are under way or planned in many coal basins around the globe. Gas-in-place determinations using canister desorption tests and CH4 isotherms are performed routinely and have provided large datasets for correlating gas transport and sorption properties with coal characteristic parameters. Publicly funded research projects have produced large datasets on the interaction of CO2 with coals. The determination of sorption isotherms, sorption capacities and rates has meanwhile become a standard approach. In this study we discuss and compare the manometric, volumetric and gravimetric methods for recording sorption isotherms and provide an uncertainty analysis. Using published datasets and theoretical considerations, water sorption is discussed in detail as an important mechanisms controlling gas sorption on coal. Most sorption isotherms are still recorded for dry coals, which usually do not represent in-seam conditions, and water present in the coal has a significant control on CBM gas contents and CO2 storage potential. This section is followed by considerations of the interdependence of sorption capacity and coal properties like coal rank, maceral composition or ash content. For assessment of the most suitable coal rank for CO2 storage data on the CO2/CH4 sorption ratio data have been collected and compared with coal rank. Finally, we discuss sorption rates and gas diffusion in the coal matrix as well as the different unipore or bidisperse models used for describing these processes. This review does not include information on low-pressure sorption measurements (BET approach) to characterize pore sizes or pore volume since this would be a review of its own. We also do not consider sorption of gas mixtures since the data base is still limited and measurement techniques are associated with large uncertainties.

New developments in coal briquetting technology  

SciTech Connect

Briquetting of coal has been with us for well over a century. In the earliest applications of coal briquetting, less valuable fine coal was agglomerated into briquettes using a wide variety of binders, including coal tar, pitch and asphalt. Eventually, roll briquetters came into more widespread use, permitting the process to become a continuous one. Coal briquetting went out of favor during the 1950s in most of the industrialized world. The major reason for this decline in use was the discovery that the coal gas distillates used for binders were harmful to human health. Also, the abundance of cheap petroleum made coal briquettes a less attractive alternative as an industrial or domestic fuel. The re-emergence of coal as a primary industrial fuel and also its increased prominence as a fuel for thermal electric power stations led to a large increase in the annual volume of coal being mined worldwide. Coal preparation technology steadily improved over the years with the general exception of fine coal preparation. The processes available for treating this size range were considerably more expensive per unit mass of coal treated than coarse coal processes. Also, costly dewatering equipment was required after cleaning to remove surface moisture. Even with dewatering, the high surface area per unit mass of fine coal versus coarse coal resulted in high moisture contents. Therefore, little incentive existed to improve the performance of fine coal processes since this would only increase the amount of wet coal fines which would have to be dealt with. With such an ever-increasing volume of coal fines being created each year, there emerged an interest in recovering this valuable product. Several schemes were developed to recover coal fines discarded in abandoned tailings impoundments by previous operations.

Risk assessment of mortality for all-cause, ischemic heart disease, cardiopulmonary disease, and lung cancer due to the operation of the world's largest coal-fired power plant  

Science Journals Connector (OSTI)

Abstract Based on recent understanding of PM2.5 health-related problems from fossil-fueled power plants emission inventories collected in Taiwan, we have determined the loss of life expectancy (LLE) and the lifetime (75-year) risks for PM2.5 health-related mortalities as attributed to the operation of the world's largest coal-fired power plant; the Taichung Power Plant (TCP), with an installed nominal electrical capacity of 5780 MW in 2013. Five plausible scenarios (combinations of emission controls, fuel switch, and relocation) and two risk factors were considered. It is estimated that the lifetime (75-y) risk for all-cause mortality was 0.3%–0.6% for males and 0.2%–0.4% for females, and LLE at 84 days in 1997 for the 23 million residents of Taiwan. The risk has been reduced to one-fourth at 0.05%–0.10% for males and 0.03%–0.06% for females, and LLE at 15 days in 2007, which was mainly attributed to the installation of desulfurization and de-NOx equipment. Moreover, additional improvements can be expected if we can relocate the power plant to a downwind site on Taiwan, and convert the fuel source from coal to natural gas. The risk can be significantly reduced further to one-fiftieth at 0.001%–0.002% for males and 0.001% for females, and LLE at 0.3 days. Nonetheless, it is still an order higher than the commonly accepted elevated-cancer risk at 0.0001% (10?6), indicating that the PM2.5 health-related risk for operating such a world-class power plant is not negligible. In addition, this study finds that a better-chosen site (involving moving the plant to the leeward side of Taiwan) can reduce the risk significantly as opposed to solely transitioning the fuel source to natural gas. Note that the fuel cost of using natural gas (0.11 USD/kWh in 2013) in Taiwan is about twice the price of using coal fuel (0.05 USD/kWh in 2013).

Upgrading low-rank coals using the liquids from coal (LFC) process  

SciTech Connect

Three unmistakable trends characterize national and international coal markets today that help to explain coal`s continuing and, in some cases, increasing share of the world`s energy mix: the downward trend in coal prices is primarily influenced by an excess of increasing supply relative to increasing demand. Associated with this trend are the availability of capital to expand coal supplies when prices become firm and the role of coal exports in international trade, especially for developing nations; the global trend toward reducing the transportation cost component relative to the market, preserves or enhances the producer`s profit margins in the face of lower prices. The strong influence of transportation costs is due to the geographic relationships between coal producers and coal users. The trend toward upgrading low grade coals, including subbituminous and lignite coals, that have favorable environmental characteristics, such as low sulfur, compensates in some measure for decreasing coal prices and helps to reduce transportation costs. The upgrading of low grade coal includes a variety of precombustion clean coal technologies, such as deep coal cleaning. Also included in this grouping are the coal drying and mild pyrolysis (or mild gasification) technologies that remove most of the moisture and a substantial portion of the volatile matter, including organic sulfur, while producing two or more saleable coproducts with considerable added value. SGI International`s Liquids From Coal (LFC) process falls into this category. In the following sections, the LFC process is described and the coproducts of the mild pyrolysis are characterized. Since the process can be applied widely to low rank coals all around the world, the characteristics of coproducts from three different regions around the Pacific Rim-the Powder River Basin of Wyoming, the Beluga Field in Alaska near the Cook Inlet, and the Bukit Asam region in south Sumatra, Indonesia - are compared.

Trends toward introducing clean coal technologies and the use of natural gas will accelerate in response to tighter environmental standards by 2000. The most important coal conversion technology for Asia, particularly China, in the long term is likely to be integrated gasification combined-cycle (IGCC), but only under the assumption of multiple products.

Chapter 5 - Coal Composition and Reservoir Characterization  

Science Journals Connector (OSTI)

Abstract Coal consists of organic and mineral matter. Fixed carbon from organic matter measures the energy output of coal during combustion. Mineral matter determines how coal responds to combustion and affects reservoir porosity and permeability. Minerals infill pores, cleats, or fractures and replace the organic composition of coal. Organic composition is grouped into maceral association as microlithotypes and macrolithotypes, the latter for megascopic field descriptions (e.g. coal cores and mine face). Coal composition controls reservoir properties such as gas adsorption capacity, gas content, porosity, and permeability. Permeability is important to gas transport from coal matrix pores to the production well. Coal permeability is a function of the width, length, and height of cleats or fractures as well as the aperture, spacing, frequency or density, and connectivity of cleats or fractures. Coal cleats or fractures formed during burial, compaction, and coalification (endogenetic) and after coalification during deformation, uplift, and erosion of the basin of deposition.

Planning the future of Botswana's coal  

Science Journals Connector (OSTI)

Botswana has vast proven deposits of steam coal, which, for a long time, the government has wanted to develop but without much success. The main objectives of this study are: to forecast possible coal exports from Botswana and the land routes for these exports; to determine the competitiveness of Botswana's coal in world steam coal trade; to make recommendations on the appropriate policy for the exploitation of this coal. To accomplish these objectives, we construct a model of the global steam coal trade and apply this model to forecast the likely optimal size of mine, timing of capacity, and choice of export port for the years 2005 and 2010 from a 2000 base forecast year. The results of our regional analysis suggest that Botswana's coal exports are competitive in Asia and Western Europe. These results are shown to be least sensitive to changes in rail transportation costs and marginal supply costs but more sensitive to changes in capital costs for mine development.

Coal extraction  

SciTech Connect

Coal is extracted using a mixed solvent which includes a substantially aromatic component and a substantially naphthenic component, at a temperature of 400/sup 0/ to 500/sup 0/C. Although neither component is an especially good solvent for coal by itself, the use of mixed solvent gives greater flexibility to the process and offers efficiency gains.

Clean Coal Diesel Demonstration Project  

SciTech Connect

A Clean Coal Diesel project was undertaken to demonstrate a new Clean Coal Technology that offers technical, economic and environmental advantages over conventional power generating methods. This innovative technology (developed to the prototype stage in an earlier DOE project completed in 1992) enables utilization of pre-processed clean coal fuel in large-bore, medium-speed, diesel engines. The diesel engines are conventional modern engines in many respects, except they are specially fitted with hardened parts to be compatible with the traces of abrasive ash in the coal-slurry fuel. Industrial and Municipal power generating applications in the 10 to 100 megawatt size range are the target applications. There are hundreds of such reciprocating engine power-plants operating throughout the world today on natural gas and/or heavy fuel oil.

The International Coal Statistics Data Base program maintenance guide  

SciTech Connect

The International Coal Statistics Data Base (ICSD) is a microcomputer-based system which contains information related to international coal trade. This includes coal production, consumption, imports and exports information. The ICSD is a secondary data base, meaning that information contained therein is derived entirely from other primary sources. It uses dBase III+ and Lotus 1-2-3 to locate, report and display data. The system is used for analysis in preparing the Annual Prospects for World Coal Trade (DOE/EIA-0363) publication. The ICSD system is menu driven and also permits the user who is familiar with dBase and Lotus operations to leave the menu structure to perform independent queries. Documentation for the ICSD consists of three manuals -- the User's Guide, the Operations Manual, and the Program Maintenance Manual. This Program Maintenance Manual provides the information necessary to maintain and update the ICSD system. Two major types of program maintenance documentation are presented in this manual. The first is the source code for the dBase III+ routines and related non-dBase programs used in operating the ICSD. The second is listings of the major component database field structures. A third important consideration for dBase programming, the structure of index files, is presented in the listing of source code for the index maintenance program. 1 fig.

is a vital energy resource, is a vital energy resource, not only for the United States, but also for many developed and developing economies around the world. Finding ways to use coal cleanly and more efficiently at lower costs is a major research and development (R&D) challenge, and an ongoing focus of activities by the U.S. Department of Energy's (DOE) Office of Fossil Energy (FE). According to a Congressional Research Service analysis, coal represents 93 percent of total U.S. - and over half of world - fossil fuel reserves (expressed in barrels of oil equivalent). Based on recent rates of domestic consumption (averaging 1 billion tons annually, 2000-2010), estimated U.S. recoverable coal reserves of nearly 261 billion short tons are sufficient to last more than 2½ centuries.

Rationale for continuing R&D in direct coal conversion to produce high quality transportation fuels  

SciTech Connect

Liquid hydrocarbon fuels will continue to play a significant role in the transportation sector in the future of both the world and the United States because of the their convenience, high energy density, and vast existing infrastructure. At present the U.S. consumes about 26% of the world supply of petroleum, but this situation is expected to change because of declining domestic production and increasing competition for imports by developing overseas economies. A scenario and time frame are developed in which declining world resources will generate a shortfall in petroleum supply that can be alleviated in part by utilizing the abundant domestic coal resource base. Continued R&D in coal conversion technology is expected to significantly reduce costs so that synfuels can compete economically at a much earlier date than previously forecast.

China's Coal: Demand, Constraints, and Externalities  

SciTech Connect

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.

Conventional coal preparation in the United States  

SciTech Connect

Processing of bituminous and anthracite coal is widely practiced in the United States and, as mentioned earlier, about 80 percent of the production of these coals is processed as clean coal in preparation plants. Subbituminous coal is not widely processed, primarily because these low rank raw coals are low in sulfur (0.5 to 1.0 percent) and relatively low in ash (8 to 15 percent). They are also relatively low in heat content due to their high inherent moisture. Lignite coals, to the best of the authors{close_quote} knowledge, are not presently being processed in Conventional Coal Preparation plants. This is due to their unstable nature and putting them in water in a coal preparation plant is likely to cause severe degradation in particle size and add to their already high inherent moisture content. The following are the benefits of clean coal processing: produces a uniform product which can be utilized more efficiently; produces a higher quality product which results in higher efficiency at the power station or the steel mill; reduces sulfur dioxide and other adverse stack emissions during coal firing which is a very important environmental consideration; reduces ash or slag handling costs by the user; reduces shipping costs; and reduces handling and storage costs. Processing any stable raw coal in a coal preparation plant will always produce a higher grade product which is a more efficient and a more environmentally acceptable fuel for use at power stations, steel mills, home heating or industrial boilers.

Jute in the world, worlds of jute  

Science Journals Connector (OSTI)

This paper is in two parts. The first sketches out the reach of jute round the world from ancient times to the present, and, through examples ranging from Brazil to Bangladesh and from Cote d'Ivoire to the USA, makes the case that jute has played such a significant role that it deserves a place in world history alongside other great commodities like spices, sugar, tea, cotton, coal, and oil, that have shaped global history. The second part of the paper opens up the worlds of jute - from peasants who grew the jute, to male and female workers in Calcutta and Dundee, to the factory owners and managers - and makes comparisons between jute settings in different countries. A key issue explored is the interplay between the economic and ideological forces inherent in the manufacturing and marketing of jute products and the local cultures and traditions of workers and peasants within which the drama of jute was played out.

Clean Coal Technology Demonstration Program: Project fact sheets 2000, status as of June 30, 2000  

SciTech Connect

The Clean Coal Technology Demonstration Program (CCT Program), a model of government and industry cooperation, responds to the Department of Energy's (DOE) mission to foster a secure and reliable energy system that is environmentally and economically sustainable. The CCT Program represents an investment of over $5.2 billion in advanced coal-based technology, with industry and state governments providing an unprecedented 66 percent of the funding. With 26 of the 38 active projects having completed operations, the CCT Program has yielded clean coal technologies (CCTs) that are capable of meeting existing and emerging environmental regulations and competing in a deregulated electric power marketplace. The CCT Program is providing a portfolio of technologies that will assure that U.S. recoverable coal reserves of 274 billion tons can continue to supply the nation's energy needs economically and in an environmentally sound manner. As the nation embarks on a new millennium, many of the clean coal technologies have realized commercial application. Industry stands ready to respond to the energy and environmental demands of the 21st century, both domestically and internationally, For existing power plants, there are cost-effective environmental control devices to control sulfur dioxide (S02), nitrogen oxides (NO,), and particulate matter (PM). Also ready is a new generation of technologies that can produce electricity and other commodities, such as steam and synthetic gas, and provide efficiencies and environmental performance responsive to global climate change concerns. The CCT Program took a pollution prevention approach as well, demonstrating technologies that remove pollutants or their precursors from coal-based fuels before combustion. Finally, new technologies were introduced into the major coal-based industries, such as steel production, to enhance environmental performance. Thanks in part to the CCT Program, coal--abundant, secure, and economical--can continue in its role as a key component in the U.S. and world energy markets. The CCT Program also has global importance in providing clean, efficient coal-based technology to a burgeoning energy market in developing countries largely dependent on coal. Based on 1997 data, world energy consumption is expected to increase 60 percent by 2020, with almost half of the energy increment occurring in developing Asia (including China and India). By 2020, energy consumption in developing Asia is projected to surpass consumption in North America. The energy form contributing most to the growth is electricity, as developing Asia establishes its energy infrastructure. Coal, the predominant indigenous fuel, in that region will be the fuel of choice in electricity production. The CCTs offer a means to mitigate potential environmental problems associated with unprecedented energy growth, and to enhance the U.S. economy through foreign equipment sales and engineering services.

Producing liquid fuels from coal: prospects and policy issues  

SciTech Connect

The increase in world oil prices since 2003 has prompted renewed interest in producing and using liquid fuels from unconventional resources, such as biomass, oil shale, and coal. This book focuses on issues and options associated with establishing a commercial coal-to-liquids (CTL) industry within the United States. It describes the technical status, costs, and performance of methods that are available for producing liquids from coal; the key energy and environmental policy issues associated with CTL development; the impediments to early commercial experience; and the efficacy of alternative federal incentives in promoting early commercial experience. Because coal is not the only near-term option for meeting liquid-fuel needs, this book also briefly reviews the benefits and limitations of other approaches, including the development of oil shale resources, the further development of biomass resources, and increasing dependence on imported petroleum. A companion document provides a detailed description of incentive packages that the federal government could offer to encourage private-sector investors to pursue early CTL production experience while reducing the probability of bad outcomes and limiting the costs that might be required to motivate those investors.

Electricity from coal and utilization of coal combustion by-products  

SciTech Connect

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

Zero emission coal  

SciTech Connect

We discuss a novel, emission-free process for producing hydrogen or electricity from coal. Even though we focus on coal, the basic design is compatible with any carbonaceous fuel. The process uses cyclical carbonation of calcium oxide to promote the production of hydrogen from carbon and water. The carbonation of the calcium oxide removes carbon dioxide from the reaction products and provides the additional energy necessary to complete hydrogen production without additional combustion of carbon. The calcination of the resulting calcium carbonate is accomplished using the high temperature waste heat from solid oxide fuel cells (SOFC), which generate electricity from hydrogen fuel. Converting waste heat back to useful chemical energy allows the process to achieve very high conversion efficiency from fuel energy to electrical energy. As the process is essentially closed-loop, the process is able to achieve zero emissions if the concentrated exhaust stream of CO{sub 2} is sequestered. Carbon dioxide disposal is accomplished by the production of magnesium carbonate from ultramafic rock. The end products of the sequestration process are stable naturally occurring minerals. Sufficient rich ultramafic deposits exist to easily handle all the world's coal.

The decline of the world’s energy intensity  

Science Journals Connector (OSTI)

Energy intensity of the total primary energy supply (TPES), total final energy consumption (TFC) and LOSSES in the conversion from TPES to TFC were analyzed for the World, OECD and Rest of the World (ROW) countries. LOSSES increased significantly for all groups of countries due to the increase of electricity production from coal in the period studied (1971–2008). Electricity share final consumption almost doubled, increasing from 8.8% to 17.2% in the period studied. However the energy intensity of LOSSES remained practically constant, which reflects the fact that the efficiency of electricity generation from coal (the main source of electricity) remained practically constant in that period. Despite the attractiveness of end-use devices running on electricity such as computers, which is typical of modern societies, the CO2 emissions are bound to increase unless coal is replaced by less carbon emitting sources such as natural gas, renewables and nuclear energy.

Clean coal  

SciTech Connect

The article describes the physics-based techniques that are helping in clean coal conversion processes. The major challenge is to find a cost- effective way to remove carbon dioxide from the flue gas of power plants. One industrially proven method is to dissolve CO{sub 2} in the solvent monoethanolamine (MEA) at a temperature of 38{sup o}C and then release it from the solvent in another unit when heated to 150{sup o}C. This produces CO{sub 2} ready for sequestration. Research is in progress with alternative solvents that require less energy. Another technique is to use enriched oxygen in place of air in the combustion process which produces CO{sub 2} ready for sequestration. A process that is more attractive from an energy management viewpoint is to gasify coal so that it is partially oxidized, producing a fuel while consuming significantly less oxygen. Several IGCC schemes are in operation which produce syngas for use as a feedstock, in addition to electricity and hydrogen. These schemes are costly as they require an air separation unit. Novel approaches to coal gasification based on 'membrane separation' or chemical looping could reduce the costs significantly while effectively capturing carbon dioxide. 1 ref., 2 figs., 1 photo.

Coal is an important source of energy and raw material for electric power production. Despite climate change legislation, growth in coal consumption thus far outpaced that of other fossil fuels in the twenty-first century. Coal is a reliable energy source, abundant, easily transported, easily traded and competitive in terms of price compared to other fossil fuels. The technology of coal preparation, coal cleaning and use in power generation is discussed. It covers issues such as coal properties and how these relate to coal performance in power generation, as well as ways to remove sulphur, mineral matter and water before coal combustion to improve the efficiency of power generation and reduce emissions from coal use.

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), 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 of 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 prospective, the results of this program will enable domestic boiler manufacturers to successfully compete in world markets for building high-efficiency coal-fired power plants.

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), 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 of 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.

Coal Bed Methane Primer  

SciTech Connect

During the second half of the 1990's Coal Bed Methane (CBM) production increased dramatically nationwide to represent a significant new source of income and natural gas for many independent and established producers. Matching these soaring production rates during this period was a heightened public awareness of environmental concerns. These concerns left unexplained and under-addressed have created a significant growth in public involvement generating literally thousands of unfocused project comments for various regional NEPA efforts resulting in the delayed development of public and fee lands. The accelerating interest in CBM development coupled to the growth in public involvement has prompted the conceptualization of this project for the development of a CBM Primer. The Primer is designed to serve as a summary document, which introduces and encapsulates information pertinent to the development of Coal Bed Methane (CBM), including focused discussions of coal deposits, methane as a natural formed gas, split mineral estates, development techniques, operational issues, producing methods, applicable regulatory frameworks, land and resource management, mitigation measures, preparation of project plans, data availability, Indian Trust issues and relevant environmental technologies. An important aspect of gaining access to federal, state, tribal, or fee lands involves education of a broad array of stakeholders, including land and mineral owners, regulators, conservationists, tribal governments, special interest groups, and numerous others that could be impacted by the development of coal bed methane. Perhaps the most crucial aspect of successfully developing CBM resources is stakeholder education. Currently, an inconsistent picture of CBM exists. There is a significant lack of understanding on the parts of nearly all stakeholders, including industry, government, special interest groups, and land owners. It is envisioned the Primer would being used by a variety of stakeholders to present a consistent and complete synopsis of the key issues involved with CBM. In light of the numerous CBM NEPA documents under development this Primer could be used to support various public scoping meetings and required public hearings throughout the Western States in the coming years.

Influence of coal thermoplastic properties on coking pressure generation: Part 2 – A study of binary coal blends and specific additives  

Science Journals Connector (OSTI)

A number of coal blends and pitch/coal blends were evaluated using rheometry, thermogravimetric analysis and microscopy to confirm and further elucidate the coking pressure mechanism previously proposed by Duffy et al. (2007) [1]. We confirm that blending a low rank, high fluidity, low coking pressure coal, with a high rank, low fluidity, high coking pressure coal can significantly reduce the coking pressure associated with the latter. Interestingly, blending does not necessarily result in a fluidity that is midway between that of the two coals; sometimes the fluidity of the blend is less than that of the low fluidity coal, especially when the coals are significantly different in rank. This occurs because the increase in complex viscosity (?*) through resolidification of the low rank, high fluidity coal counteracts the reduction in ?* resulting from softening of the high rank, low fluidity coal. It has also been confirmed that the ?* of the resultant blend can be estimated from the ?* of each component coal using a logarithmic additivity rule commonly employed for polymer blends. Polarised light microscopy has indicated that the degree of mixing between coals of different rank is minimal, with fusion restricted to the particle surface. It is therefore inappropriate to think of such a coal blend in the same way as a single coal, since each component coal behaves relatively independently. This limited fusion is important for understanding the coking pressure mechanism for blends. It is proposed here that the lower rank coal, which softens at lower temperature, is able to expand into the interparticle voids between the high rank coal that is yet to soften, and these voids can create channels for volatiles to traverse. Then, and importantly, when the high rank coal begins to expand, the pore structure developed in the resolidified structures of the low rank coal can facilitate removal of volatiles, while the resolidified material may also act as a suitable sorbent for volatile matter. This is considered to be the primary mechanism by which coal blending is able to alleviate coking pressure, and applies to addition of inert material also. Addition of a coal tar pitch was found to increase fluidity but also to extend the thermoplastic range to lower temperatures. This caused an increase in the swelling range, which was accompanied by a long plateau in ?*, a feature which has previously been observed for certain high fluidity, high pressure coals. Elasticity and ?* at the onset of expansion were also higher for both the pitch impregnated coals and the high pressure blends, which supports previous findings for singly charged high pressure coals, and confirms the potential use of such criteria for identifying potentially dangerous coals/blends.

Introduction of clean coal technology in Japan  

SciTech Connect

Coal is an abundant resource, found throughout the world, and inexpensive and constant in price. For this reason, coal is expected to play a role as one of the energy supply sources in the world. The most critical issues to promote utilization of coal are to decrease the environmental load. In this report, the history, outline and recent developments of the clean coal technology in Japan, mainly the thermal power generation technology are discussed. As recent topics, here outlined first is the technology against global warming such as the improvement of steam condition for steam turbines, improvement of power generation efficiency by introducing combined generation, carbon neutral combined combustion of biomass, and carbon dioxide capture and storage (CCS) technology. Also introduced are outlines of Japanese superiority in application technology against NOx and SO{sub 2} which create acid rain, development status of the technical improvement in the handling method for coal which is a rather difficult solid-state resource, and utilization of coal ash.

U.S. zero emission coal alliance techology  

SciTech Connect

For coal to maintain its major role in supplying the world's energy, eventually all emissions to the atmosphere must be eliminated. Not only must conventional pollutants, like sulfur compounds and dust particles be kept out of the air, but also the far larger quantities of carbon dioxide that result from the combustion of carbon. We present a new technology for coal-based power that generates hydrogen from carbon and water, avoids emissions to the atmosphere, and disposes of the carbon dioxide as inert, solid mineral carbonates. Based on the available resources, coal power is sustainable for centuries. Our zero emission technology makes coal energy as clean as renewable energy.

Environmental and economic challenges to coal`s future in China  

SciTech Connect

Coal accounts for approximately 75% of China`s total primary energy consumption, and is by far the largest contributor to air pollution. The highest growth sector for coal consumption is the power sector, accounting for about 36 percent of total coal consumption in 1993. Over the 1994--2010 period most new, large power plants are expected to be coal-fired. Therefore, the availability and price of coal, as well as environmental constraints will be critical to foreign investors evaluating coal and power projects in China. The purpose of this paper is to provide useful technical, economic and environmental information and analysis on coal and the power sectors of China. The target audiences are potential investors and government energy and environmental policy people. This paper suggests a number of important energy and environmental policy issues that need to be addressed in a timely fashion in order to promote adequate levels of investment in coal and power developments in China. Although this paper highlights problems faced by foreign investors in coal and power, it is important to balance these problems against the large investment opportunities developing in these sectors.

Clean Coal Program Research Activities  

SciTech Connect

Although remarkable progress has been made in developing technologies for the clean and efficient utilization of coal, the biggest challenge in the utilization of coal is still the protection of the environment. Specifically, electric utilities face increasingly stringent restriction on the emissions of NO{sub x} and SO{sub x}, new mercury emission standards, and mounting pressure for the mitigation of CO{sub 2} emissions, an environmental challenge that is greater than any they have previously faced. The Utah Clean Coal Program addressed issues related to innovations for existing power plants including retrofit technologies for carbon capture and sequestration (CCS) or green field plants with CCS. The Program focused on the following areas: simulation, mercury control, oxycoal combustion, gasification, sequestration, chemical looping combustion, materials investigations and student research experiences. The goal of this program was to begin to integrate the experimental and simulation activities and to partner with NETL researchers to integrate the Program's results with those at NETL, using simulation as the vehicle for integration and innovation. The investigators also committed to training students in coal utilization technology tuned to the environmental constraints that we face in the future; to this end the Program supported approximately 12 graduate students toward the completion of their graduate degree in addition to numerous undergraduate students. With the increased importance of coal for energy independence, training of graduate and undergraduate students in the development of new technologies is critical.

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.

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.

Chapter 2 - Coal as Multiple Sources of Energy  

Science Journals Connector (OSTI)

Abstract Coal as multiple sources of energy is mined for its solid and gas-, oil-, and condensate-derived hydrocarbons as well as liquefied for synfuels. More than 50 countries mine coal as feedstock for power plants to generate electricity but only six of these countries monopolize 73% of the total recoverable coalbed gas resources of the world. Worldwide, about 30,000 coal mine explosions are caused by methane and carbon dioxide, and to prevent outbursts and emissions, underground, surface, and abandoned coalmine gases are exploited for industrial and commercial uses. Still, a large volume of unrecovered fugitive coalmine gases is released as global greenhouse gas emissions. An alternative source for foreign oil dependent countries is synfuels from coal liquefaction technology. Also, coal-derived hydrocarbons are a part of the conventional resources that is, gas, oil, and condensate sourced from coal but expelled into adjoining reservoirs, are attractive alternative energy sources.

The First Coal Plants  

NLE Websites -- All DOE Office Websites (Extended Search)

Coal Plants Coal Plants Nature Bulletin No. 329-A January 25, 1969 Forest Preserve District of Cook County George W. Dunne, President Roland F. 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.

SciTech Connect

Coal Production 1992 provides comprehensive information about US coal production, the number of mines, prices, productivity, employment, productive capacity, and recoverable reserves to a wide audience including Congress, Federal and State agencies, the coal industry, and the general public. In 1992, there were 3,439 active coal mining operations made up of all mines, preparation plants, and refuse operations. The data in Table 1 cover the 2,746 mines that produced coal, regardless of the amount of production, except for bituminous refuse mines. Tables 2 through 33 include data from the 2,852 mining operations that produced, processed, or prepared 10 thousand or more short tons of coal during the period, except for bituminous refuse, and includes preparation plants with 5 thousand or more employee hours. These mining operations accounted for over 99 percent of total US coal production and represented 83 percent of all US coal mining operations in 1992.

The status of coal briquetting technology in Korea  

SciTech Connect

Anthracite is the only indigenous fossil fuel resource produced in Korea and is an important main source of residential fuel. Due to its particular characteristics, the best way to use Korean coal is in the form of briquettes, called {open_quotes}Yontan.{close_quotes} The ability to use this coal as briquettes was a great discovery made nearly 50 years ago and since then, has made a great contribution to the energy consumption of low and middle income households. Korean anthracite in coal briquette form has been used widely for household heating purposes. Collieries in Korea produced no more than one million tons of anthracite annually in the 1960s. Production, however, increased substantially up to about 17 million tons per year in the mid-1970s. In 1986, Korea succeeded in raising its coal production to 24.2 million tons, which was the maximum production level achieved by the Korean coal industrial sector. Since then, anthracite production has fallen. In 1991, coal output dropped to 15.1 million tons, a decrease of 12.2 percent from the 17.2 million tons produced in 1990, due to falling coal demand and rising labor costs. The role of coal as an energy source will be more important in the future to meet projected economic growth in Korea. While the production of indigenous Korean anthracite is expected to decrease under a coal mining rationalization policy, imports of bituminous coal will increase rapidly and will be used as an oil substitute in industry and power generation. In this chapter, general aspects of the Korean coal industry and coal utilization for residential uses, especially the Yontan coal briquetting techniques, are discussed. In addition, coal briquetting technology applications suitable for the APEC region will be presented.

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

SciTech Connect

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

Pricing of Australia's coking coal exports: A regional hedonic analysis  

Science Journals Connector (OSTI)

Black coal is Australia's most important export commodity, but the profitability of the domestic coal industry has been low relative to the mining sector average. As a consequence, a key policy issue in Australia has been the extent to which Japan's coal pricing and investment policies have influenced coal market outcomes. In this paper, a regional hedonic pricing model of Australia's coking coal exports is estimated for the period JFY1989 to 1996. Non-Japan regional intercept dummy variables were found to be significantly different from zero, although these varied across coal categories and years. However, the empirical evidence indicates that Japan does not pay significantly lower prices relative to other major export markets for coking coal of a given quality.

A fresh look at coal-derived liquid fuels  

SciTech Connect

35% of the world's energy comes from oil, and 96% of that oil is used for transportation. The current number of vehicles globally is estimated to be 700 million; that number is expected to double overall by 2030, and to triple in developing countries. Now consider that the US has 27% of the world's supply of coal yet only 2% of the oil. Coal-to-liquids technologies could bridge the gap between US fuel supply and demand. The advantages of coal-derived liquid fuels are discussed in this article compared to the challenges of alternative feedstocks of oil sands, oil shale and renewable sources. It is argued that pollutant emissions from coal-to-liquid facilities could be minimal because sulfur compounds will be removed, contaminants need to be removed for the FT process, and technologies are available for removing solid wastes and nitrogen oxides. If CO{sub 2} emissions for coal-derived liquid plants are captured and sequestered, overall emissions of CO{sub 2} would be equal or less than those from petroleum. Although coal liquefaction requires large volumes of water, most water used can be recycled. Converting coal to liquid fuels could, at least in the near term, bring a higher level of stability to world oil prices and the global economy and could serve as insurance for the US against price hikes from oil-producing countries. 7 figs.

Blackout: coal, climate and the last energy crisis  

SciTech Connect

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

The objective of the present research is to study the chemical reactivity of a mixture of methyl alcohol and aqueous sodium hydroxide solution in the temperature range 298 to 363 K, and a caustic concentration of 0 to 10 wt. %, on an Iowa bituminous coal. The sample studied was collected from coal zone 4, equivalent to most historical references to Laddsdale coal. The coals in this zone are typical high-sulfur, high-ash middle Pennsylvania Cherokee group coals. The apparent rank is high-volatile C bituminous coal. The relatively high content of sulfur and 23 other elements in these coals is related to near neutral (6-8) pH conditions in the depositional and early diagenetic environments, and to postdepositional sphalerite/calcite/pyrite/kaolinite/barite mineralization.

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.

This report covers the progress made on the title project during the current reporting period. Four major areas of inquiry are being pursued. Advanced solid state NMR methods are being developed to assay the distribution of the various important functional groups in coals that determine the reactivity of coals. Other methods are being developed which will also determine how these functional groups are linked together. A third area of investigation concerns how molecular mobility in coals impacts NMR relaxation times, which is important for interpretation of such data in terms of the mobile phase in coals model. Along the same lines we are also using these studies to establish protocols for obtaining the best quantitative response from coals in sold state C-13 NMR spectra. This quarter we have focussed on spin lattice relaxation measurements for several of the Argonne coals.

Coal Storage and Transportation  

Science Journals Connector (OSTI)

Abstract Coal preparation, storage, and transportation are essential to coal use. Preparation plants, located near to the mine, remove some inorganic minerals associated with raw coal. Coal is transported from the mines to the point of consumption, often an electric generating plant, by rail, barge and trucks. Railroads are the predominant form of coal transportation within a country. Global coal trade, movement by large ocean-going vessels, continues to increase. At the end use site, the coal is crushed, ground, and the moisture content reduced to the proper specifications for end use. Coal is stored at various points in the supply chain. Processed coal will weather and oxidize, changing its properties; it can self-ignite, unless precautions are taken. Technology in use today is similar to that used in previous decades. Performance improvements have come from improved software and instruments that deliver real-time data. These improve management of sub-processes in the coal supply chain and reduce costs along the supply chain.

Influence of coal as an energy source on environmental pollution  

SciTech Connect

This article considers the influence of coal energy on environmental pollution. Coal is undoubtedly part of the greenhouse problem. The main emissions from coal combustion are sulfur dioxide (SO{sub 2}), nitrogen oxides (NOx), particulates, carbon dioxide (CO{sub 2}), and mercury (Hg). Since 1980, despite a 36% increase in electricity generation and more than a 50% increase in coal use, electric utility SO{sub 2} and NOx emissions have declined significantly. Globally, the largest source of anthropogenic greenhouse gas (GHG) emissions is CO{sub 2} from the combustion of fossil fuels - around 75% of total GHG emissions covered under the Kyoto Protocol. At the present time, coal is responsible for 30-40% of world CO{sub 2} emission from fossil fuels.

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.

Coal plasticity at high heating rates and temperatures. Final technical progress report  

SciTech Connect

Plastic coals are important feedstocks in coke manufacture, coal liquefaction, gasification, and combustion. During these processes, the thermoplastic behavior of these coals is also important since it may contribute to desirable or undesirable characteristics. For example, during liquefaction, the plastic behavior is desired since it leads to liquid-liquid reactions which are faster than solid-liquid reactions. During gasification, the elastic behavior is undesired since it leads to caking and agglomeration of coal particles which result in bed bogging in fixed or fluidized bed gasifiers. The plastic behavior of different coals was studied using a fast-response plastometer. A modified plastometer was used to measure the torque required to turn at constant angular speed a cone-shaped disk embedded in a thin layer of coal. The coal particles were packed between two metal plates which are heated electrically. Heating rates, final temperatures, pressures, and durations of experiment ranged from 200--800 K/s, 700--1300 K, vacuum-50 atm helium, and 0--40 s, respectively. The apparent viscosity of the molten coal was calculated from the measured torque using the governing equation of the cone-and-plate viscometer. Using a concentrated suspension model, the molten coal`s apparent viscosity was related to the quantity of the liquid metaplast present during pyrolysis. Seven coals from Argonne National Laboratory Premium Coal Sample Bank were studied. Five bituminous coals, from high-volatile to low-volatile bituminous, were found to have very good plastic behavior. Coal type strongly affects the magnitude and duration of plasticity. Hvb coals were most plastic. Mvb and lvb coals, though the maximum plasticity and plastic period were less. Low rank coals such as subbituminous and lignite did not exhibit any plasticity in the present studies. Coal plasticity is moderately well correlated with simple indices of coal type such as the elemental C,O, and H contents.

EIA - Will carbon capture and storage reduce the world's carbon dioxide  

Gasoline and Diesel Fuel Update (EIA)

Will carbon capture and storage reduce the world's carbon dioxide emissions? Will carbon capture and storage reduce the world's carbon dioxide emissions? International Energy Outlook 2010 Will carbon capture and storage reduce the world'ss carbon dioxide emissions? The pursuit of greenhouse gas reductions has the potential to reduce global coal use significantly. Because coal is the most carbon-intensive of all fossil fuels, limitations on carbon dioxide emissions will raise the cost of coal relative to the costs of other fuels. Under such circumstances, the degree to which energy use shifts away from coal to other fuels will depend largely on the costs of reducing carbon dioxide emissions from coal-fired plants relative to the costs of using other, low-carbon or carbon-free energy sources. The continued widespread use of coal could rely on the cost and availability of carbon capture and storage (CCS) technologies that capture carbon dioxide and store it in geologic formations.

The challenge with coal has always been the management of its mineral matter, sulfur and nitrogen contents during use. The carbon content of fuels, including coal, is a more recent concern. With clean coal technologies, there are opportunities for ensuring the sustained use of coal for a very long time. The clean coal technologies of today are already capable of reducing, if not eliminating, harmful emissions. The technologies of the future will allow coal to be burned with greatly reduced emissions, thus eliminating the necessity to treat them after they occur.

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.

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.

Capture and Use of Coal Mine Ventilation-Air Methane  

NLE Websites -- All DOE Office Websites (Extended Search)

Capture and use of Coal Mine Capture and use of Coal Mine Ventilation - air Methane Background Methane emissions from coal mines represent about 10 percent of the U.S. anthropogenic methane released to the atmosphere. Methane-the second most important non-water greenhouse gas-is 21 times as powerful as carbon dioxide (CO 2 ) in its global warming potential. Ventilation-air methane (VAM)-the exhaust air from underground coal mines-is the largest source of coal mine methane, accounting for about half of the methane emitted from coal mines in the United States. Unfortunately, because of the low methane concentration (0.3-1.5 percent) in ventilation air, its beneficial use is difficult. However, oxidizing the methane to CO 2 and water reduces its global warming potential by 87 percent. A thermal

This document is a quarterly status report of the Coal Combustion Science Project that is being conducted at the Combustion Research Facility, Sandia National Laboratories. The information reported is for Apr-Jun 1993. The objective of this work is to support the Office of Fossil Energy in executing research on coal combustion science. This project consists of basic research on coal combustion that supports both the PETC Direct Utilization Advanced Research and Technology Development Program, and the International Energy Agency Coal Combustion Science Project. The objective of the kinetics and mechanisms of pulverized coal char combustion task is to characterize the combustion behavior of selected US coals under conditions relevant to industrial pulverized coal-fired furnaces. Work is being done in four areas: kinetics of heterogeneous fuel particle populations; char combustion kinetics at high carbon conversion; the role of particle structure and the char formation process in combustion and; unification of the Sandia char combustion data base. This data base on the high temperature reactivities of chars from strategic US coals will permit identification of important fuel-specific trends and development of predictive capabilities for advanced coal combustion systems. The objective of the fate of inorganic material during coal combustion task is the establish a quantitative understanding of the mechanisms and rates of transformation, fragmentation, and deposition of inorganic material during coal combustion as a function of coal type, particle size and temperature, the initial forms and distribution of inorganic species in the unreacted coal, and the local gas temperature and composition. In addition, optical diagnostic capabilities are being developed for in situ, real-time detection of inorganic vapor species and surface species during ash deposition. Selected papers have been indexed separately for inclusion in the Energy Science and Technology Database.

STEO November 2012 - coal supplies  

U.S. Energy Information Administration (EIA) Indexed Site

Despite drop in domestic coal production, U.S. coal exports to reach Despite drop in domestic coal production, U.S. coal exports to reach record high in 2012. 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 in China  

SciTech Connect

The article gives an overview of the production and use of coal in China, for power generation and in other sectors. Coal use for power generation was 850 million tonnes in 2003 and 800 million tonnes in the non-power sector. The majority of power will continue to be produced from coal, with a trend towards new larger pulverised coal fired units and introduction of circulating fluidised bed combustors. Stricter regulations are forcing introduction of improved pollution control technologies. It seems likely that China will need international finance to supplement private and state investment to carry out a programme to develop and apply clean coal technologies. The author concludes that there is evidence of a market economy being established but there is a need to resolve inconsistencies with the planned aspects of the economy and that additional policies are needed in certain sectors to achieve sustainable development. 1 ref., 2 figs., 2 tabs.

By 2020, however, the U.S. share of world carbon emissions is projected to decline to 20 percent, with China's share increasing to 21 percent. The substantial increase in carbon emissions in China over the period is attributable to expectations of strong economic growth and the country's continuing heavy reliance on fossil fuels, especially coal which remains the country's primary source of energy.

CO2 Sequestration Potential of Texas Low-Rank Coals  

SciTech Connect

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 primary objectives for this reporting period were to construct a coal geological model for reservoir analysis and to continue acquisition of data pertinent to coal characterization that would help in determining the feasibility of carbon dioxide sequestration. Structural analysis and detailed correlation of coal zones are important for reservoir analysis and modeling. Evaluation of existing well logs indicates local structural complexity that complicates interpretations of continuity of the Wilcox Group coal zones. Therefore, we have begun searching for published structural maps for the areas of potential injection CO{sub 2}, near the coal-fired power plants. Preliminary evaluations of data received from Anadarko Petroleum Corporation suggest that coal properties and gas content and chemical composition vary greatly among coal seams. We are assessing the stratigraphic and geographic distributions and the weight of coal samples that Anadarko has provided to select samples for further laboratory analysis. Our goal is to perform additional isotherm analyses with various pure and/or mixed gases to enhance our characterization model. Additionally, we are evaluating opportunities for field determination of permeability with Anadarko, utilizing one of their wells.

Effects of pulverized coal fly-ash addition as a wet-end filler in papermaking  

SciTech Connect

This experimental study is based on the innovative idea of using pulverized coal fly ash as a wet-end filler in papermaking. This is the first evaluation of the possible use of fly ash in the paper industry. Coal-based thermal power plants throughout the world are generating fly ash as a solid waste product. The constituents of fly ash can be used effectively in papermaking. Fly ash has a wide variation in particle size, which ranges from a few micrometers to one hundred micrometers. Fly ash acts as an inert material in acidic, neutral, and alkaline papermaking processes. Its physical properties such as bulk density (800-980 kg/m{sup 3}), porosity (45%-57%), and surface area (0.138-2.3076 m{sup 2}/g) make it suitable for use as a paper filler. Fly ash obtained from thermal power plants using pulverized coal was fractionated by a vibratory-sieve stack. The fine fraction with a particle size below 38 micrometers was used to study its effect on the important mechanical-strength and optical properties of paper. The effects of fly-ash addition on these properties were compared with those of kaolin clay. Paper opacity was found to be much higher with fly ash as a filler, whereas brightness decreased as the filler percentage increased Mechanical strength properties of the paper samples with fly ash as filler were superior to those with kaolin clay.

Upgrading of low-rank coals for conventional and advanced combustion systems  

SciTech Connect

Low-rank coals, subbituminous, lignitic, and brown coals, have a ubiquitous presence in the world, being found in all continents. Close to half of the world`s estimated coal resources are low- rank coals. Many countries have no alternative economic source of energy. In the lower 48 states of the United States, there are 220 billion tons of economically recoverable reserves of lignite and subbituminous coal. Add to this quantity 5 trillion tons of predominantly subbituminous coal in Alaska, and the combined amount represents the largest supply of the lowest-cost fuels available for generating electric power in the United States. However, to use these coals cost-effectively and in an environmentally acceptable way, it is imperative that their properties and combustion/gasification behavior be well understood. The Energy and Environmental Research Center (EERC) takes a cradle-to-grave approach (i.e., mining, precleaning, combustion/gasification, postcleaning, and reuse and disposal of residues) for all aspects of coal processing and utilization. The environmental impact of these activities must be matched with the appropriate technologies. Experience over many years has shown that variations in coal and ash properties have a critical impact on design, reliability and efficiency of operation, and environmental compliance when low-rank coals are burned in conventional systems. This chapter reviews the significant technical issues of beneficiation, which includes reduction in moisture as well as ash (including sulfur), in relation to low-rank coal properties and their impact on conventional and advanced power systems. Finally, the development and utilization of low-rank coal resources are briefly discussed in view of policy, economic, and strategic issues.

Modelling coal gasification  

Science Journals Connector (OSTI)

Coal gasification processes in a slurry-feed-type entrained-flow gasifier are studied. Novel simulation methods as well as numerical results are presented. We use the vorticity-stream function method to study the characteristics of gas flow and a scalar potential function is introduced to model the mass source terms. The random trajectory model is employed to describe the behaviour of slurry-coal droplets. Very detailed results regarding the impact of the O2/coal ratio on the distribution of velocity, temperature and concentration are obtained. Simulation results show that the methods are feasible and can be used to study a two-phase reacting flow efficiently.

Coal liquefaction process  

DOE Patents (OSTI)

A process is described for the liquefaction of coal wherein raw feed coal is dissolved in recycle solvent with a slurry containing recycle coal minerals in the presence of added hydrogen at elevated temperature and pressure. The highest boiling distillable dissolved liquid fraction is obtained from a vacuum distillation zone and is entirely recycled to extinction. Lower boiling distillable dissolved liquid is removed in vapor phase from the dissolver zone and passed without purification and essentially without reduction in pressure to a catalytic hydrogenation zone where it is converted to an essentially colorless liquid product boiling in the transportation fuel range. 1 fig.

Coal characterisation for \\{NOx\\} prediction in air-staged combustion of pulverised coals  

Science Journals Connector (OSTI)

A series of world-traded coal samples has been tested using the Imperial College high temperature wire mesh apparatus (HTWM) in order to assess the relationship between high temperature (1600°C) char nitrogen content and \\{NOx\\} formation in Hemweg Power Station (in the Netherlands) using deep furnace air staging. A linear relationship between high temperature char nitrogen and \\{NOx\\} formation has been confirmed. These results suggest that high temperature char N content is the main factor limiting \\{NOx\\} emissions with deep air-staged combustion. Char N and (hence apparently deep air-staged NOx) can be predicted with an accuracy of approximately ±20% for most coals from the coal proximate and ultimate analysis—but this might not be sufficient for stations operating close to their emission limits. Measuring high temperature char N directly reduces the likely uncertainty in deep air-staged \\{NOx\\} emissions for coals (and most blends) to approximately ±10%. Its use should be considered on a routine basis for coal selection on plants employing this technology.

Coal - U.S. Energy Information Administration (EIA) - U.S. Energy  

Gasoline and Diesel Fuel Update (EIA)

Summary Summary The U.S. coal industry rebounded in 2010, with coal exports showing impressive gains and domestic production up over the previous year. Metallurgical coal export prices hit record levels as weather problems continued to plague Australian producers, and steel-hungry China and India continued to import relatively large amounts of metallurgical coal. U.S. domestic coal price increases moderated for the electric power sector and declined for industrial plants and for commercial and institutional users. Positive trends established in 2010 are expected to carry over to 2011. Domestic coal consumption as well as metallurgical coal exports are expected to increase as U.S. and most other industrial economies continue to grow. Coal prices should continue to increase at a moderate pace. As

Kansas coal resources and their potential for utilization in the near future  

SciTech Connect

Preliminary evaluation of deep coal resources in Kansas indicates nearly 50 billion tons (45 billion MT) of coal in eastern Kansas. The Cherokee Group and Marmaton Groups of Middle Pennsylvanian age are the important coal-bearing geologic units. Most of the coal beds are thin, with only a limited amount (1.85 billion tons or 1.68 billion MT) from coal beds exceeding 42 in. (105 cm) in thickness. Most of these coal thicknesses were determined from geophysical logs run for oil and gas tests, and the potential for a much larger resource of thick coal exists in several areas of the state. Depths of this deep-coal resource range from 100 ft (30 m) down to approximately 3,000 ft (900 m) in the deeper parts of the western Cherokee basin.

Evolving performance characteristics of clean coal technologies

The United States Department of Energy (US DOE) Clean Coal Technology Demonstration Program (also referred to as the CCT Program) is a government and industry cofunded technology development effort to demonstrate a new generation of innovative coal utilization processes in a series of {open_quotes}semicommercial{close_quotes} facilities. These demonstrations are on a scale large enough to generate all the data, from design, construction, and operation, that are necessary for the private sector to judge commercial potential and make informed, confident decisions on commercial readiness. The projects in the program are demonstrating technologies that will encompass advanced electric power generation systems, high-performance pollution control devices, coal processing for clean fuels and industrial applications. The innovative CCTs being demonstrated offer tremendous potential as solutions to many complex problems in a rapidly changing arena dominated by energy, economic, and environmental issues. These issues include the following: air quality; global climate change; energy security; international competitiveness; acid rain; power production; and technology awareness. These technologies are expected to be of particular importance to the utility industry. Power production in the United States, particularly in the form of electricity, is expected to increase rapidly during the next 20 years. The growth in electricity consumption between 1990 and 2000 translates into the need for at least an additional 200,000 MWe of capacity by 2010. The ability to continue to use coal to produce electricity and as a source of industrial heat and power is critical. In the United States approximately 86 percent of coal is critical. The CCT Program is developing through demonstration new power and steam production systems using coal-based technologies that will permit coal to be a clean, efficient, reliable source of affordable energy.

Effect of bulk density of coking coal on swelling pressure  

Science Journals Connector (OSTI)

Abstract Coking coals are the important raw materials for the iron and steel industries and play an important role on its sustainable development, especially on the stamp-charging coke making with the characteristics of increasing the bulk density. There is a significance on the reasonable usage of the coking coal resource with the reduced production cost, improved efficiency of the economy to develop the stamp-charging coke making technology. Important effects of the density of coking coal on the coking and caking properties were investigated. In the article, the maximum values of swelling pressure and variation of Laowan gas coal and Xinjian 1/3 coking coal, Longhu fat coal and Didao coking coal, which were mined at Shenyang and Qitaihe respectively, were investigated under different bulk densities during the coking. The results showed that when the values of density increased from 0.85 ton/m3 to 1.05 ton/m3, for the Laowan gas coal, swelling pressure variation and even the maximum value changed slightly. The swelling pressure was 3.63 \\{KPa\\} when the density was improved to 1.05 ton/m3; for the Xinjian 1/3 coking coal, the values of swelling pressure changed significantly and the maximum values was 82.88 \\{KPa\\} with the density improved to 1.05 when the coal was heated to 600°C. The coke porosity, which was investigated by automatic microphotometer, decreased from 47.4% to 33.1% with the increasing of the density from 0.85 ton/m3 to 1.05 ton/m3, and the decreased value was 14.3%. Meanwhile, the pore structures of four cokes were characterized by an optical microscope.

Rail Coal Transportation Rates  

Gasoline and Diesel Fuel Update (EIA)

Methodology Methodology EIA uses the confidential version of the STB Waybill data, which includes actual revenue for shipments that originate and terminate at specific locations. The STB Waybill data are a sample of all rail shipments. EIA's 2011 report describes the sampling procedure. EIA aggregates the confidential STB data to three different levels: national, coal-producing basin to state, and state to state. EIA applies STB withholding rules to the aggregated data to identify records that must be suppressed to protect business-sensitive data. Also, EIA adds additional location fields to the STB data, identifying the mine from which the coal originates, the power plant that receives the coal, and, in some cases, an intermediate delivery location where coal is terminated by the initial carrier but then

Proximate analysis of coal  

SciTech Connect

This lab experiment illustrates the use of thermogravimetric analysis (TGA) to perform proximate analysis on a series of coal samples of different rank. Peat and coke are also examined. A total of four exercises are described. These are dry exercises as students interpret previously recorded scans. The weight percent moisture, volatile matter, fixed carbon, and ash content are determined for each sample and comparisons are made. Proximate analysis is performed on a coal sample from a local electric utility. From the weight percent sulfur found in the coal (determined by a separate procedure the Eschka method) and the ash content, students calculate the quantity of sulfur dioxide emissions and ash produced annually by a large coal-fired electric power plant.

Coal consumption and economic growth in China  

Science Journals Connector (OSTI)

The aim of this paper is to re-examine the relationship between coal consumption and real GDP of China with the use of panel data. This paper applies modern panel data techniques to help shed light on the importance of the heterogeneity among different regions within China. Empirical analyses are conducted for the full panel as well as three subgroups of the panel. The empirical results show that coal consumption and GDP are both I(1) and cointegrated in all regional groupings. Heterogeneity is found in the GDP equation of the full panel. The regional causality tests reveal that the coal consumption–GDP relationship is bidirectional in the Coastal and Central regions whereas causality is unidirectional from GDP to coal consumption in the Western region. Thus, energy conservation measures will not adversely affect the economic growth of the Western region but such measures will likely encumber the economy of the Coastal and Central regions, where most of the coal intensive industries are concentrated.

World Energy Consumption by Fuel Type, 1970-2020  

Gasoline and Diesel Fuel Update (EIA)

0 0 Notes: Natural gas is projected to be the fastest-growing component of primary world energy consumption, more than doubling between 1997 and 2020. Gas accounts for the largest increment in electricity generation (41 percent of the total increment of energy used for electricity generation). Combined-cycle gas turbine power plants offer some of the highest commercially available plant efficiencies, and natural gas is environmentally attractive because it emits less sulfur dioxide, carbon dioxide, and particulate matter than does oil or coal. In the IEO2000 projection, world natural gas consumption reaches the level of coal by 2005, and by 2020 gas use exceeds coal by 29 percent. Oil currently provides a larger share of world energy consumption than any other energy source and is expected to remain in that position

Potential for thermal coal and Clean Coal Technology (CCT) in the Asia-Pacific  

SciTech Connect

The Coal Project was able to make considerable progress in understanding the evolving energy situation in Asia and the future role of coal and Clean Coal Technologies. It is clear that there will be major growth in consumption of coal in Asia over the next two decades -- we estimate an increase of 1.2 billion metric tons. Second, all governments are concerned about the environmental impacts of increased coal use, however enforcement of regulations appears to be quite variable among Asian countries. There is general caution of the part of Asian utilities with respect to the introduction of CCT's. However, there appears to be potential for introduction of CCT's in a few countries by the turn of the century. It is important to emphasize that it will be a long term effort to succeed in getting CCT's introduced to Asia. The Coal Project recommends that the US CCT program be expanded to allow the early introduction of CCT's in a number of countries.

COAL LOGISTICS. Tracking U.S. Coal Exports  

SciTech Connect

COAL LOGISTICS has the capability to track coal from a U. S. mine or mining area to a foreign consumer`s receiving dock. The system contains substantial quantities of information about the types of coal available in different U. S. coalfields, present and potential inland transportation routes to tidewater piers, and shipping routes to and port capabilities in Italy, Japan, South Korea, Taiwan, and Thailand. It is designed to facilitate comparisons of coal quality and price at several stages of the export process, including delivered prices at a wide range of destinations. COAL LOGISTICS can be used to examine coal quality within or between any of 18 U. S. coalfields, including three in Alaska, or to compare alternative routes and associated service prices between coal-producing regions and ports-of-exit. It may be used to explore the possibilities of different ship sizes, marine routes, and foreign receiving terminals for coal exports. The system contains three types of information: records of coal quality, domestic coal transportation options, and descriptions of marine shipment routes. COAL LOGISTICS contains over 3100 proximate analyses of U. S. steam coals, usually supplemented by data for ash softening temperature and Hardgrove grindability; over 1100 proximate analyses for coals with metallurgical potential, usually including free swelling index values; 87 domestic coal transportation options: rail, barge, truck, and multi-mode routes that connect 18 coal regions with 15 U. S. ports and two Canadian terminals; and data on 22 Italian receiving ports for thermal and metallurgical coal and 24 coal receiving ports along the Asian Pacific Rim. An auxiliary program, CLINDEX, is included which is used to index the database files.

Coal rank is a factor of great importance in plasticity development during carbonization, since only some bituminous coals swell in a satisfactory manner and then resolidify to produce good commercial cokes. ... Diessel studied the carbonization behavior of the inertinite macerals in Australian coals by carrying out tests up to 1000 °C where the optical characteristics of the coked entities were correlated with their noncoked counterparts. ... For instance, large-scale coking experiments of some Australian coals containing more than 45% inertinite produced good quality coke, while a Carboniferous coal with that high of an inertinite content gave only a very poor coke. ...

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

SciTech Connect

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

Spatial characteristic of coal geochemistry: Some methodological considerations  

SciTech Connect

Identification and analysis of spatial patterns in coal geochemistry have important implications in coal science, notably for coal quality prediction, resource evaluation, and for interpretation of geological controls on coal geochemistry. Contour maps of elemental concentration for coal deposits may be reconstructed from raw data by using one of a number of interpolation methods commonly used within the earth sciences. Within a Geographic Information System (GIS), these surfaces may then be analyzed, and be integrated or compared with the distribution surfaces of other attributes such as coal petrography, seam thickness or mineralogy. The exact shape of the reconstructed geochemical contour map will vary depending on the method of interpolation selected and how the researcher chooses to divide data into classes by selection of class intervals. This paper and the associated poster presentation examine the range of output which may result when some of these methodological parameters are varied. Guidelines for selection of interpolation methodologies and data classification are suggested. A data set consisting of 14 coal samples from the Bullmoose mine area in northeastern British Columbia, Canada is used to illustrate the difference in coal geochemical surface reconstruction when using different interpolation techniques and class intervals.

Multi-parameter on-line coal bulk analysis  

SciTech Connect

This was a four-year grant that was given a no cost extension for one more year. The purpose of the grant was to develop a pulsed neutron-based technique that could measure on-line all the major and minor elements in coal. Such measurements would allow the continuous monitoring of bulk parameters such as coal heating value (BTU/lb), volatile matter, moisture etc., deemed important to the coal industry. Such parameters, along with the continuous measurement of elements such as sulfur and sodium, are of major economic and environmental concern, and their measurement would assist in a more efficient use of the coal-fired boilers, as well as limiting emissions controlled by the 1990 Clean Air Act Amendments. It was hoped that this study would lead to the development of a technique able to create a marketable product, an On-Line Elemental Coal Analyzer. The study was separated in the following major parts: (1) Devise an efficient system for the detection of gamma rays; (2) Prior to experimentation, perform modeling and simulations for items such as detector shielding, coal sample configuration, and neutron tube collimation; (3) Develop a computer code for data reduction and analysis; (4) Measure the elemental composition of various coal samples; and (5) Design a prototype, on-line elemental coal analyzer, based on the PFTNA principle.

Method of extracting coal from a coal refuse pile  

DOE Patents (OSTI)

A method of extracting coal from a coal refuse pile comprises soaking the coal refuse pile with an aqueous alkali solution and distributing an oxygen-containing gas throughout the coal refuse pile for a time period sufficient to effect oxidation of coal contained in the coal refuse pile. The method further comprises leaching the coal refuse pile with an aqueous alkali solution to solubilize and extract the oxidized coal as alkali salts of humic acids and collecting the resulting solution containing the alkali salts of humic acids. Calcium hydroxide may be added to the solution of alkali salts of humic acid to form precipitated humates useable as a low-ash, low-sulfur solid fuel.

Deep coal resources in the Cherokee Group (middle Pennsylvanian) in eastern Kansas  

SciTech Connect

Evaluation of over 800 gamma-ray/density and gamma-ray/neutron logs run for oil and gas tests in eastern Kansas shows a wide distribution of coal in the Cherokee Group in this area. With nearly 300 million tons (270 million metric tons) of high-volatile bituminous coal produced in southeastern Kansas, this group was important for further evaluation. Studies of the coals in the Cherokee Group too deep to strip mine in the Cherokee basin and the Forest City basin indicate a coal resource of nearly 50 billion tons (45 billion metric tons). This figure represents coal from 27 different coal beds in the three reliability categories of measured, indicated, and inferred. Most of the coal is recognized as thin bedded (< 28 in. or < 70 cm) like most of the coal beds in the outcrop belt in southeastern Kansas. Six coals beds with a total of over 1.4 billion tons (1.3 billion metric tons) of resources are present where coal thicknesses exceed 42 in. (105 cm) in parts of 12 different counties. Resource quantities of the Cherokee Group coal beds were made using Pacer and Garnet software developed for the National Coal Resources Data System (NCRDS) of the US Geological Survey.

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

SciTech Connect

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

Coal combustion system  

DOE Patents (OSTI)

In a coal combustion system suitable for a gas turbine engine, pulverized coal is transported to a rich zone combustor and burned at an equivalence ratio exceeding 1 at a temperature above the slagging temperature of the coal so that combustible hot gas and molten slag issue from the rich zone combustor. A coolant screen of water stretches across a throat of a quench stage and cools the combustible gas and molten slag to below the slagging temperature of the coal so that the slag freezes and shatters into small pellets. The pelletized slag is separated from the combustible gas in a first inertia separator. Residual ash is separated from the combustible gas in a second inertia separator. The combustible gas is mixed with secondary air in a lean zone combustor and burned at an equivalence ratio of less than 1 to produce hot gas motive at temperature above the coal slagging temperature. The motive fluid is cooled in a dilution stage to an acceptable turbine inlet temperature before being transported to the turbine.

Advanced Coal Wind Hybrid: Economic Analysis  

SciTech Connect

Growing concern over climate change is prompting new thinking about the technologies used to generate electricity. In the future, it is possible that new government policies on greenhouse gas emissions may favor electric generation technology options that release zero or low levels of carbon emissions. The Western U.S. has abundant wind and coal resources. In a world with carbon constraints, the future of coal for new electrical generation is likely to depend on the development and successful application of new clean coal technologies with near zero carbon emissions. This scoping study explores the economic and technical feasibility of combining wind farms with advanced coal generation facilities and operating them as a single generation complex in the Western US. The key questions examined are whether an advanced coal-wind hybrid (ACWH) facility provides sufficient advantages through improvements to the utilization of transmission lines and the capability to firm up variable wind generation for delivery to load centers to compete effectively with other supply-side alternatives in terms of project economics and emissions footprint. The study was conducted by an Analysis Team that consists of staff from the Lawrence Berkeley National Laboratory (LBNL), National Energy Technology Laboratory (NETL), National Renewable Energy Laboratory (NREL), and Western Interstate Energy Board (WIEB). We conducted a screening level analysis of the economic competitiveness and technical feasibility of ACWH generation options located in Wyoming that would supply electricity to load centers in California, Arizona or Nevada. Figure ES-1 is a simple stylized representation of the configuration of the ACWH options. The ACWH consists of a 3,000 MW coal gasification combined cycle power plant equipped with carbon capture and sequestration (G+CC+CCS plant), a fuel production or syngas storage facility, and a 1,500 MW wind plant. The ACWH project is connected to load centers by a 3,000 MW transmission line. In the G+CC+CCS plant, coal is gasified into syngas and CO{sub 2} (which is captured). The syngas is burned in the combined cycle plant to produce electricity. The ACWH facility is operated in such a way that the transmission line is always utilized at its full capacity by backing down the combined cycle (CC) power generation units to accommodate wind generation. Operating the ACWH facility in this manner results in a constant power delivery of 3,000 MW to the load centers, in effect firming-up the wind generation at the project site.

Characterization and preparation of Dipka coal from Korba coalfield in India  

SciTech Connect

The Korba coalfield is one of the most important non-coking coalfields in India because of large reserves and high annual production. The Dipka coal, from Korba coalfield, will be cleaned in the first private, non-coking coal washery being constructed in Bilaspur, India, as a joint venture of U.S. and Indian companies. The US Agency for International Development (USAID) has assisted these companies in an effort to demonstrate advanced coal beneficiation methods at this washery. Because of increasing dependence on coal-based power generation in India, coal production and preparation play an important role in this country`s economy and environmental management. USAID, through US Department of Energy, is providing the necessary technical support in activities related to coal preparation in India. An overview of these activities will be presented. An analysis of the Dipka coal was performed with emphasis on a large sample recently collected. The effects of raw coal variability and crushing on washability characteristics and energy recovery in coal preparation were studied. This study was conducted at the Federal Energy Technology Center (FETC) in Pittsburgh. Based on an analysis conducted and flowsheets developed at FETC, the Dipka coal was cleaned at the Central Fuel Research Institute`s pilot-plant in Dhanbad (India). The economic benefits of Dipka coal cleaning for power generation and the status of Bilaspur Washery construction and operation will be highlighted.

Dry cleaning of Turkish coal  

SciTech Connect

This study dealt with the upgrading of two different type of Turkish coal by a dry cleaning method using a modified air table. The industrial size air table used in this study is a device for removing stones from agricultural products. This study investigates the technical and economical feasibility of the dry cleaning method which has never been applied before on coals in Turkey. The application of a dry cleaning method on Turkish coals designated for power generation without generating environmental pollution and ensuring a stable coal quality are the main objectives of this study. The size fractions of 5-8, 3-5, and 1-3 mm of the investigated coals were used in the upgrading experiments. Satisfactory results were achieved with coal from the Soma region, whereas the upgrading results of Hsamlar coal were objectionable for the coarser size fractions. However, acceptable results were obtained for the size fraction 1-3 mm of Hsamlar coal.

Coal investment and long-term supply and demand outlook for coal in the Asia-Pacific Region  

SciTech Connect

The theme of this symposium to look ahead almost a quarter century to 2020 gives one the freedom to speculate more than usual in projections for coal. It is important to attempt to take a long term look into the future of coal and energy, so that one can begin to prepare for major changes on the horizon. However, it would be a mistake to believe that the crystal ball for making long term projections is accurate for 2020. Hopefully it can suggest plausible changes that have long term strategic importance to Asia`s coal sector. This paper presents the medium scenario of long term projects of coal production, consumption, imports and exports in Asia. The second part of the paper examines the two major changes in Asia that could be most important to the long term role of coal. These include: (1) the impact of strict environmental legislation on energy and technology choices in Asia, and (2) the increased role of the private sector in all aspects of coal in Asia.

Process for coal liquefaction employing selective coal feed  

DOE Patents (OSTI)

An improved coal liquefaction process is provided whereby coal conversion is improved and yields of pentane soluble liquefaction products are increased. In this process, selected feed coal is pulverized and slurried with a process derived solvent, passed through a preheater and one or more dissolvers in the presence of hydrogen-rich gases at elevated temperatures and pressures, following which solids, including mineral ash and unconverted coal macerals, are separated from the condensed reactor effluent. The selected feed coals comprise washed coals having a substantial amount of mineral matter, preferably from about 25-75%, by weight, based upon run-of-mine coal, removed with at least 1.0% by weight of pyritic sulfur remaining and exhibiting vitrinite reflectance of less than about 0.70%.

Chapter 8 - Coal Seam Degasification  

Science Journals Connector (OSTI)

Abstract The chapter discusses various techniques for coal seam degasification. All coal seams are gassy but they differ in their degree of gassiness. Pre-mining and post-mining techniques for underground coal mines are discussed. With good planning, 50–80% of in-situ gas in coal can be removed before mining improving both safety and productivity. Similarly, 50–80% of gas from mined-out areas (gobs) can be removed to minimize ventilation air requirements. Gas transport in underground mines and economics of coal seam degasification are also discussed.

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

Science Journals Connector (OSTI)

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

Coal-oil slurry preparation  

DOE Patents (OSTI)

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

Characteristics of coking coal burnout  

SciTech Connect

An attempt was made to clarify the characteristics of coking coal burnout by the morphological analysis of char and fly ash samples. Laboratory-scale combustion testing, simulating an ignition process, was carried out for three kinds of coal (two coking coals and one non-coking coal for reference), and sampled chars were analyzed for size, shape and type by image analysis. The full combustion process was examined in industrial-scale combustion testing for the same kinds of coal. Char sampled at the burner outlet and fly ash at the furnace exit were also analyzed. The difference between the char type, swelling properties, agglomeration, anisotropy and carbon burnout were compared at laboratory scale and at industrial scale. As a result, it was found that coking coals produced chars with relatively thicker walls, which mainly impeded char burnout, especially for low volatile coals.

Underground Coal Thermal Treatment  

SciTech Connect

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.

Extraction, separation, and analysis of high sulfur coal  

SciTech Connect

Coal Reaction Study: The results of the reaction of aqueous cupric chloride with Illinois {number sign}6 coal are listed on page 21. These results indicate that the oxidative desulfurization of coal with cupric chloride is more complex and less effective than previously reported. Although almost all the pyritic and sulfate sulfur are removed from the coal, the organic sulfur is actually reported to have increased. This may be due to an actual increase in the organic sulfur through a side reaction of the pyrite, or it may be caused by inaccuracy of the ASTM method when large proportions of chloro substituents are present. The amount of chlorine added to the coal (from 0 to 3.18%) is quite large and counterproductive. Most importantly, the amount of non-combustible ash has increased from 15.48 to 51.21%, most likely in the form of copper. This will dramatically decrease both the efficiency of combustion in terms of altering the heat capacity of the coal as well as decrease the amount of energy produced per ton of coal. As a result, it is quite evident that this method of desulfurization needs some modification prior to further exploitation.

The Coal Logistics System: Documentation and user's guide  

SciTech Connect

The Coal Logistics System (CLS) has the capability to track coal from a US mine or mining area to a foreign consumer's receiving dock. The system contains substantial quantities of information about the types of coal available in different US coalfields, present and potential inland transportation routes to tidewater piers, and shipping routes to and port capabilities in the five importing nations now included. It is designed to facilitate comparisons of coal quality and price at several stages of the export process, including delivered prices at a wide range of destinations from Trieste to Vado Ligure in Italy, and from Muroran in northern Japan, to Sri Racha, near Bangkok, along the Asian Pacific Rim. The CLS can also be used to examine coal quality within or between any of 18 US coalfields, including three in Alaska, or compare alternative routes and associated service prices between coal producing regions and ports-of-exit. It may be used to explore the possibilities of different ship sizes, marine routes, and foreign receiving terminals for coal exports. The CLS interacts with users through a series of menus that provide the user with simple choices. 30 figs.

An analysis of China's coal supply and its impact on China's future economic growth  

Science Journals Connector (OSTI)

Many people believe that China's economic growth can continue almost indefinitely. For a manufacturing-based economy such as China's to continue to grow, it needs an adequate supply of inexpensive energy. To date, this energy growth has primarily come from coal, but China's indigenous coal supplies are now falling short of the amount needed to support this growth. In this situation, the status of China's future coal supply will be very important for China's future economic development. Our analysis shows that China's ultimate recoverable coal reserves equal 223.6×109 MT, and its production will peak between 2025 and 2030, with peak production of approximately 3.9×109 MT. The extent to which China can import coal in the future is uncertain. With rising coal demand, this combination is likely to create a significant challenge to China's future economic development.

Coal surface control for advanced physical fine coal cleaning technologies  

SciTech Connect

This final report presents the research work carried out on the Coal Surface Control for Advanced Physical Fine Coal Cleaning Technologies project, sponsored by the US Department of Energy, Pittsburgh Energy Technology Center (DOE/PETC). The project was to support the engineering development of the selective agglomeration technology in order to reduce the sulfur content of US coals for controlling SO[sub 2] emissions (i.e., acid rain precursors). The overall effort was a part of the DOE/PETCs Acid Rain Control Initiative (ARCI). The overall objective of the project is to develop techniques for coal surface control prior to the advanced physical fine coal cleaning process of selective agglomeration in order to achieve 85% pyrite sulfur rejection at an energy recovery greater than 85% based on run-of-mine coal. The surface control is meant to encompass surface modification during grinding and laboratory beneficiation testing. The project includes the following tasks: Project planning; methods for analysis of samples; development of standard beneficiation test; grinding studies; modification of particle surface; and exploratory R D and support. The coal samples used in this project include three base coals, Upper Freeport - Indiana County, PA, Pittsburgh NO. 8 - Belmont County, OH, and Illinois No. 6 - Randolph County, IL, and three additional coals, Upper Freeport - Grant County- WV, Kentucky No. 9 Hopkins County, KY, and Wyodak - Campbell County, WY. A total of 149 drums of coal were received.

Coal fires in China over the last decade: A comprehensive review  

Science Journals Connector (OSTI)

Abstract Coal fires pose great threats to valuable energy resources, the environment, and human health and safety. They occur in numerous countries in the world. It is well-known that China, the largest coal producer and user globally, is one of the countries that have badly suffered from coal fires. Thus, over the course of the last decade, a lot of local research studies on coal fires in China have been published in international and Chinese scientific journals. The goal of this paper is to set the scene on past and current coal fire research in China. In this review we explore multidisciplinary investigations undertaken during the last decade associated with coal fires in China including fire detection, modeling, the assessment of environmental and human health impacts as well as fire-fighting engineering. We outline a systematic framework of research on coal fires and address inter-relations of sub-topics within this systematic framework. Additionally, the scientific and technical studies and their advantages, shortcomings and challenges for coal mine administrations are discussed. It is hoped that this comprehensive overview provides scientific guidance for management and coordination of coal fire projects.

Underground coal gasification: a brief review of current status  

SciTech Connect

Coal gasification is a promising option for the future use of coal. Similarly to gasification in industrial reactors, underground coal gasification (UCG) produces syngas, which can be used for power generation or for the production of liquid hydrocarbon fuels and other valuable chemical products. As compared with conventional mining and surface gasification, UCG promises lower capital/operating costs and also has other advantages, such as no human labor underground. In addition, UCG has the potential to be linked with carbon capture and sequestration. The increasing demand for energy, depletion of oil and gas resources, and threat of global climate change lead to growing interest in UCG throughout the world. In this article, we review the current status of this technology, focusing on recent developments in various countries.

Characterization of selected Ohio coals to predict their conversion behavior relative to 104 North American Coals. [Factors correlating with liquefaction behavior  

SciTech Connect

Twenty-six coal samples from Ohio were collected as washed and seam samples, and lithobodies within the seams. Characterization of these samples included determination of % maceral, % anti R/sub max/, LTA, chlorine content and proximate/ultimate and qualitative mineral analyses. These data were compared to data from a similar project by Yarzab, R.F., et al., 1980 completed at Pennsylvania State University using tetralin as the hydrogen donor solvent. The characteristics of these coals were correlated with liquefaction conversion and other data accrued on 104 North American coals by statistical analyses. Utilizing percent carbon, sulfur, volatile matter, reflectance, vitrinite and total reactive macerals, Q-mode cluster analysis demonstrated that Ohio coals are more similar to the coals of the Interior province than to those of the Appalachian province. Linear multiple regression analysis for the 104 North American coals provided a prediction equation for conversion (R = .96). The predicted conversion values for the samples range from 58.8 to 79.6%, with the Lower Kittanning (No. 5) and the Middle Kittanning (No. 6) coal seams showing the highest predicted percent conversion (respectively, 73.4 and 72.2%). The moderately low FSI values for the No. 5 and No. 6 coals (respectively, 2.5 and 3) and their moderately high alkaline earth content (respectively, 0.69 and 0.74%) suggest that these coals possess the best overall properties for conversion. Stepwise regression has indicated that the most important coal characteristics affecting conversion are, in decreasing order of importance: % volatile matter, % vitrinite and % total sulfur. Conversion processes can be expected to produce higher yields with Ohio coals due to the presence of such mineral catalysts as pyrite and kaolinite. It is believed that the presence of these disposable catalysts increases the marketability of Ohio coals.

Moist caustic leaching of coal  

DOE Patents (OSTI)

A process for reducing the sulfur and ash content of coal. Particulate coal is introduced into a closed heated reaction chamber having an inert atmosphere to which is added 50 mole percent NaOH and 50 mole percent KOH moist caustic having a water content in the range of from about 15% by weight to about 35% by weight and in a caustic to coal weight ratio of about 5 to 1. The coal and moist caustic are kept at a temperature of about 300.degree. C. Then, water is added to the coal and caustic mixture to form an aqueous slurry, which is washed with water to remove caustic from the coal and to produce an aqueous caustic solution. Water is evaporated from the aqueous caustic solution until the water is in the range of from about 15% by weight to about 35% by weight and is reintroduced to the closed reaction chamber. Sufficient acid is added to the washed coal slurry to neutralize any remaining caustic present on the coal, which is thereafter dried to produce desulfurized coal having not less than about 90% by weight of the sulfur present in the coal feed removed and having an ash content of less than about 2% by weight.

In 1992 the United States Agency for International Development (USAID) started sponsoring general projects in the Energy and Environmental Sector to improve health and well-being, to improve the efficiency of the existing fuel and energy base, and to assist in the establishment of a strong private sector. Coal Cleaning Program, covered in this report, is one of the recently completed projects by Burns and Roe, which is a prime USAID contractor in the field of energy and environment for the NIS. The basis for coal cleaning program is that large coal resources exist in northeast Kazakstan and coal represents the major fuel for heat and electricity generation at present and in the foreseeable future. The coal mined at Karaganda and Ekibastuz, the two main coal mining areas of Kazakstan, currently contains up to 55% ash, whereas most boilers in Kazakstan are designed to fire a coal with an ash content no greater than 36%. The objective of the task was to determine optimum, state-of-the-art coal cleaning and mining processes which are applicable to coals in Kazakstan considering ultimate coal quality of 36% ash, environmental quality, safety and favorable economics.

Coal Ash Corrosion Resistant Materials Testing Program  

SciTech Connect

The "Coal Ash Corrosion Resistant Materials Testing Program" is being conducted by The Babcock & Wilcox Company (B&W), the U.S. Department of Energy (DOE) and the Ohio Coal Development Office (OCDO) at Reliant Energy?s Niles plant in Niles, Ohio to provide full-scale, in-situ testing of recently developed boiler superheater materials. Fireside corrosion is a key issue for improving efficiency of new coal fired power plants and improving service life in existing plants. In November 1998, B&W began development of a system to permit testing of advanced tube materials at metal temperatures typical of advanced supercritical steam temperatures (1100°F and higher) in a boiler exhibiting coal ash corrosive conditions. Several materials producers including Oak Ridge National Laboratory (ORNL) contributed advanced materials to the project. In the spring of 1999 a system consisting of three identical sections, each containing multiple segments of twelve different materials, was installed. The sections are cooled by reheat steam, and are located just above the furnace entrance in Niles? Unit #1, a 110 MWe unit firing high sulfur Ohio coal. In November 2001 the first section was removed for thorough metallurgical evaluation after 33 months of operation. The second and third sections remain in service and the second is expected to be removed in the fall of 2003; the last is tentatively planned for the fall of 2004. This paper describes the program; its importance; the design, fabrication, installation and operation of the test system; materials utilized; experience to date; and results of the evaluation of the first section.

Coal production forecast and low carbon policies in China  

Science Journals Connector (OSTI)

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

Application of GIS on forecasting water disaster in coal mines  

SciTech Connect

In many coal mines of China, water disasters occur very frequently. It is the most important problem that water gets inrush into drifts and coal faces, locally known as water gush, during extraction and excavation. Its occurrence is controlled by many factors such as geological, hydrogeological and mining technical conditions, and very difficult to be predicted and prevented by traditional methods. By making use of overlay analysis of Geographic Information System, a multi-factor model can be built to forecast the potential of water gush. This paper introduced the method of establishment of the water disaster forecasting system and forecasting model and two practical successful cases of application in Jiaozuo and Yinzhuang coal mines. The GIS proved helpful for ensuring the safety of coal mines.

Caking coals are treated in a slurry including alkaline earth metal hydroxides at moderate pressures and temperatures in air to form noncaking carbonaceous material. Hydroxides such as calcium hydroxide, magnesium hydroxide or barium hydroxide are contemplated for slurrying with the coal to interact with the agglomerating constituents. The slurry is subsequently dewatered and dried in air at atmospheric pressure to produce a nonagglomerating carbonaceous material that can be conveniently handled in various coal conversion and combustion processes.

Selective mining and beneficiation at Grootegeluk coal mine Waterberg Coalfield, South Africa  

SciTech Connect

Grootegeluk Coal Mine, situated in the Waterberg Coalfield in the Northern Province of South Africa, ranks among the largest open pit coal mines in the world in terms of run of mine tonnage. Commissioned in 1980 to provide steel producer Iscor with coking coal, Grootegeluk currently produces 53 Mt of coking coal per annum. At present Iscor consumes 1.2 Mt of coking coal while Matimba, the world's largest direct dry cooled PowerStation consumes an additional 12.6 Mt. Fine washing and screening plants currently beneficiate the run of mine feed from this multi-seam multi-product mine. Although the Waterberg Coalfield contains approximately 50% of South Africa's coal reserves, Grootegeluk is the only operating mine in this coalfield. The coal seams of the Waterberg Coalfield occur in the Volksrust and Vryheids formations of the Karoo Sequence. Numerous coal seams ranging from a few millimeters up to 8 meters occur over a stratigraphic thickness of at least 120 meters. These coal seams are grouped into eleven coal bearing zones that can be correlated across the coalfield. The coal- and coalbearing strata in the Waterberg are of late Paleozoic to early Mesozoic age. Coal from the Volksrust formation is autochthonous while the coal from the Vryheid formation is allochthonous. To ensure that sufficient geological and analytical data are obtained from exploration boreholes an extensive sampling procedure was established with washability data ranging from 1,35 to 2,20 g/cc. The analyses indicated that certain parts of the coalbearing strata is not suitable for the production of coking coal due to the high phosphorus content or the poor coking properties. This resulted in an open pit with 11 mining benches. The upper parts of the deposit is extracted by conventional shovel and truck operations while the coal seams of the lower part of the deposit are mined selectively with hydraulic shovels. At Grootegeluk down the hole geophysics (natural gamma) are used for grade control and also to quantify the effect of over- or undermining on the various mining benches. Reconciliation between the run of mine material dispatched to the various plants and their resulted yields/qualities are done regularly.

Theoretical principles of use of coal fractions with different densities for combustion  

SciTech Connect

It is reasonable to complement the conventional preparation of steam coal involving the removal of ash components and pyritic sulfur by the isolation of the lightest organic fractions, which possess enhanced performance characteristics. These fractions are smoothly saleable both on the domestic and world markets for effective pulverized-coal combustion via new combustion technologies. Heavier (inertinite) fractions of the coal preparation concentrate marketed at lower prices can be considered appropriate fuel for burning in circulating fluidized-bed combustion systems. 13 refs., 5 figs., 4 tabs.

PRODUCTION OF CARBON PRODUCTS USING A COAL EXTRACTION PROCESS  

SciTech Connect

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

Relative permeabilities of gas and water for different rank coals  

Science Journals Connector (OSTI)

Characteristics of gas–water two-phase flow through coal seams play crucial roles in water depletion and gas production associated with coalbed methane (CBM) recovery. One of the most important characteristic is the relative permeability of gas and water which is largely dependent on gas/water saturations in coal, varying with coal ranks. For better understanding of the seepage mechanism of the gas–water flow in coal, the relative permeabilities of gas and water in different rank coals selected from south Qinshui Basin have been investigated under various gas/water saturations through water replacement with methane using an unsteady-state method. The results have shown that the ratio of effective methane permeability and absolute permeability is obviously increasing with rank, implying that the gas slippage of high rank coal has more significant effect than the low rank coal. A series of relative permeability curves for selected coals have been obtained. All of these curves show that the selected coals are featured by smaller methane permeabilities and narrow spans of two-phase flow regions and lower relative permeability, and have low methane permeabilities under irreducible water condition as well. The experiments also revealed that the selected coals exhibit high residual water saturation with low relative permeabilities of gas and water. With increasing of the maximal vitrinite reflectance, the irreducible water saturation exhibits a U-shaped tendency whereas the methane permeability under the irreducible water condition generally increases. The irreducible water saturation slightly increases with increasing of vitrinite and weakly decreases as inertinite increases, while the methane permeability under irreducible water condition is negatively related with vitrinite and positively related to inertinite to some extent. The experimental data were further parameterized to correlate the relative permeabilities of methane and water to gas saturation, showing that a correlation of power function can fit the experiments well. As a result, a permeability model incorporated with coal rank and maceral compositions with gas saturation was developed to predict the relative permeabilities of gas (methane) and water in coals.
