    The United States produced 242 million short tons of coal in the first quarter of 1993, a decrease of 6 percent (14 million short tons) from the amount produced during the first quarter of 1992. The decrease was due to a decline in production east of the Mississippi River. All major coal-producing States in this region had lower coal production levels led by West Virginia, which produced 5 million short tons less coal. The principal reasons for the overall drop in coal output compared to a year earlier were: A decrease in demand for US coal in foreign markets; a slower rate of producer/distributor stock build-up; and a drawn-down of electric utility coal stocks. Distribution of US coal in the first quarter of 1993 was 10 million short tons lower than in the first quarter of 1992, with 5 million short tons less distributed to both electric utilities and overseas markets. The average price of coal delivered to electric utilities during the first quarter of 1993 was $28.65 per short ton, the lowest value since the first quarter of 1980. Coal consumption in the first quarter of 1993 was 230 million short tons, 4 percent higher than in the first quarter of 1992, due primarily to a 5-percent increase in consumption at electric utility plants. Total consumer stocks, at 153 million short tons, and electric utility stocks, at 144 million short tons, were at their lowest quarterly level since the end of 1989. US. coal exports totaled 19 million short tons, 6 million short tons less than in the first quarter of 1992, and the lowest quarterly level since 1988. The decline was primarily due to a 1-million-short-ton drop in exports to each of the following destinations: Italy, France, Belgium and Luxembourg, and Canada.

    This Review of a Proposed Quartery Coal Publication contains findings and recommendations regarding the content of a new summary Energy Information Administration (EIA) coal and coke publication entitled The Quarterly Coal Review (QCR). It is divided into five sections: results of interviews with selected EIA data users; identification of major functions of the coal and coke industries; analysis of coal and coke data collection activities; evaluation of issues conerning data presentation including recommendations for the content of the proposed QCR; and comparison of the proposed QCR with other EIA publications. Major findings and recommendations are as follows: (1) User interviews indicate a definite need for a compehensive publication that would support analyses and examine economic, supply and demand trends in the coal industry; (2) the organization of the publication should reflect the natural order of activities of the coal and coke industries. Based on an analysis of the industries, these functions are: production, stocks, imports, exports, distribution, and consumption; (3) current EIA coal and coke surveys collect sufficient data to provide a summary of the coal and coke industries on a quarterly basis; (4) coal and coke data should be presented separately. Coke data could be presented as an appendix; (5) three geographic aggregations are recommended in the QCR. These are: US total, coal producing districts, and state; (6) coal consumption data should be consolidated into four major consumer categories: electric utilities, coke plants, other industrial, and residential commercial; (7) several EIA publications could be eliminated by the proposed QCR.

    In the second quarter of 1993, the United States produced 235 million short tons of coal. This brought the total for the first half of 1993 to 477 million short tons, a decrease of 4 percent (21 million short tons) from the amount produced during the first half of 1992. The decrease was due to a 26-million-short-ton decline in production east of the Mississippi River, which was partially offset by a 5-million-short-ton increase in coal production west of the Mississippi River. Compared with the first 6 months of 1992, all States east of the Mississippi River had lower coal production levels, led by West Virginia and Illinois, which produced 9 million short tons and 7 million short tons less coal, respectively. The principal reasons for the drop in coal output for the first 6 months of 1993 compared to a year earlier were: a decrease in demand for US coal in foreign markets, particularly the steam coal markets; a draw-down of electric utility coal stocks to meet the increase in demand for coal-fired electricity generation; and a lower producer/distributor stock build-up. Distribution of US coal in the first half of 1993 was 15 million short tons lower than in the first half of 1992, with 13 million short tons less distributed to overseas markets and 2 million short tons less distributed to domestic markets.

    The Quarterly Coal Report provides comprehensive information about coal production, exports, imports, receipts, consumption, and stocks in the United States. The data presented in this report were collected and published by the Energy Information Administration (EIA) to fulfill its data collection and dissemination responsibilities as specified in the Federal Energy Administration Act of 1974 (P.L. 93-275) as amended. This issue shows detailed quarterly data for April-June 1985, aggregated quarterly historical and projected data for 1980 through 1986, and aggregated annual historical and projected data for 1960 through 1995. All data for 1984 and previous years are final. All 1985 data are preliminary and subject to revision. During the first and second quarters of 1985, the US coal industry continued to return to normal operations after the threat of a strike by US coal miners in 1984. For the first 6 months of 1985 the industry showed the following developments: Coal production was only 2.4% less than in the same period of 1984, when it reached a record January-June total. Coal exports were 10.0% higher than their 1984 level for the same time period. The United States imported 52.3% more coal than it did in the first 6 months of 1984, chiefly from Colombia. Domestic coal consumption reached a record-setting level for January-June, 3.6% greater than the previous record in 1984.

    1995-12-01

    The objective of this research project is to determine the molecular and structural changes that occur in swelled coal as a result of oxidation and moisture los both in the presence and absence of light using our newly developed EPR spin probe method. The proposed study will make it possible to deduce the molecular accessibility distribution swelled, {ital oxidized} APCS coal for each rank as a function of (1) size (up to 6 nm) and shape, (2) the relative acidic/basic reactive site distributions, and (3) the role of hydrogen bonding as a function of swelling solvents. The advantage of the EPR method is that it permits molecules of selected shape, size and chemical reactivity to be used as probes of molecular accessible regions of swelled coal. From such data an optimum catalyst can be designed to convert oxidized coal into a more convenient form and methods can be devised to lessen the detrimental weathering process. This quarter we have continued to examine the effect of exposure of light before alkylation versus after O-alkylation of the coal structure. The variation in uptake of spin probe VII (amine group) is depicted in figure 1 for Wyodak-Anderson. Before O-alkylation, a significant decrease occurred in the uptake of VII with increasing exposure to ambient light. This suggests that partial break-up of the hydrogen bond network occurs, making it possible to wash out more of the spin probes. This effect was eliminated if the coal was O-alkylated after exposure to sunlight (Figure 2). The removal of the source of hydrogen bonding is responsible for the lack of spin probe up-take variation with time of exposure to light. Further experiments have shown that the data in Figures 1 and 2 is reproducible with a deviation of less than {+-} 10%. It has also been observed that if Wyodak-Anderson coal is exposed to sunlight before swelling, the oscillatory up-take of spin probe VII as a function of percent pyridine is essentially removed.

    The Clean Air Act Amendments of 1990 identify a number of hazardous air pollutants (HAPs) as candidates for regulation. Should regulations be imposed on HAP emissions from coal-fired power plants, a sound understanding of the fundamental principles controlling the formation and partitioning of toxic species during coal combustion will be needed. With support from the Federal Energy Technology Center (FETC), the Electric Power Research Institute, and VTT (Finland), Physical Sciences Inc. (PSI) has teamed with researchers from USGS, MIT, the University of Arizona (UA), the University of Kentucky (UKy), the University of Connecticut, and Princeton University to develop a broadly applicable emissions model useful to regulators and utility planners. The new Toxics Partitioning Engineering Model (ToPEM) will be applicable to all combustion conditions including new fuels and coal blends, low-NOx combustion systems, and new power generation plants. Development of ToPEM will be based on PSI`s existing Engineering Model for Ash Formation (EMAF). During the past quarter the final program coal, from the Wyodak seam in the Powder River Basin, was acquired and distributed. Extensive coal characterization and laboratory work is underway to develop and test new sub-models. Coal characterization in the past quarter included direct identification of the modes of occurrence of various trace inorganic species in coal and ash using unique analytical techniques such as XAFS analysis and selective leaching. Combustion testing of the bituminous coals continued and additional data were obtained on trace element vaporization in the combustion zone. Studies of post-combustion trace element transformations, such as mercury speciation in the flue gas, were also begun in the last quarter.

    DOE's program for the conversion of coal to liquid fuels was begun by two of DOE's predecessor agencies: Office of Coal Research (OCR) in 1962, and Bureau of Mines, US Department of the Interior, in the 1930's. Current work is aimed at improved process configurations for both catalytic and non-catalytic processes to provide more attractive processing economics and lower capital investment. The advantage of coal liquefaction is that the entire range of liquid products, especially boiler fuel, distillate fuel oil, and gasoline, can be produced from coal by varying the type of process and operating conditions used in the process. Furthermore, coal-derived liquids have the potential for use as chemical feedstocks. To provide efficient and practical means of utilizing coal resources, DOE is supporting the development of several conversion processes that are currently in the pilot plant stage. DOE, together with the Electric Power Research Institue, has contracted with fourteen projects are described brieflly: funding, description, status, history, and progress in the current quarter.

    SciTech Connect (OSTI)

    1980-04-01

    In DOE's program for the conversion of coal to gaseous fuels both high-and low-Btu gasification processes are being developed. High-Btu gas can be distributed economically to consumers in the same pipeline systems now used to carry natural gas. Low-Btu gas, the cheapest of the gaseous fuels produced from coal, can be used economically only on site, either for electric power generation or by industrial and petrochemical plants. High-Btu natural gas has a heating value of 950 to 1000 Btu per standard cubic foot, is composed essentially of methane, and contains virtually no sulfur, carbon monoxide, or free hydrogen. The conversion of coal to High-Btu gas requires a chemical and physical transformation of solid coal. Coals have widely differing chemical and physical properties, depending on where they are mined, and are difficult to process. Therefore, to develop the most suitable techniques for gasifying coal, DOE, together with the American Gas Association (AGA), is sponsoring the development of several advanced conversion processes. Although the basic coal-gasification chemical reactions are the same for each process, each of the processes under development have unique characteristics. A number of the processes for converting coal to high-Btu gas have reached the pilot plant Low-Btu gas, with a heating value of up to 350 Btu per standard cubic foot, is an economical fuel for industrial use as well as for power generation in combined gas-steam turbine power cycles. Because different low-Btu gasification processes are optimum for converting different types of coal, and because of the need to provide commercially acceptable processes at the earliest possible date, DOE is sponsoring the concurrent development of several basic types of gasifiers (fixed-bed, fluidized-bed, and entrained-flow).

    This report describes work completed during the fourth quarter of a three year project to study the effects of mild chemical pretreatment on coal dissolution reactivity during low severity liquefaction or coal/oil coprocessing. The overall objective of this research is to elucidate changes in the chemical and physical structure of coal by pretreating with methanol or other simple organic solvent and a trace amount of hydrochloric acid and measure the influence of these changes on coal dissolution reactivity. This work is part of a larger effort to develop a new coal liquefaction or coal/oil coprocessing scheme consisting of three main process steps: (1) mile pretreatment of the feed coal to enhance dissolution reactivity and dry the coal, (2) low severity thermal dissolution of the pretreated coal to obtain a very reactive coal-derived residual material amenable to upgrading, and (3) catalytic upgrading of the residual products to distillate liquids.

    This project proposes a new method for removing organic sulfur from Illinois coals using readily available farm products. It proposes to use air and vegetable oils to disrupt the coal matrix, oxidize sulfur forms, increase volatiles, and desulfurize coal. This will be accomplished by impregnating coals with polyunsaturated oils, converting the oils to their hydroperoxides, and heating. Since these oils are relatively inexpensive and easily applied, this project could lead to a cost effective method for removing organic sulfur from coals. Moreover, the oils are environmentally safe; they will produce no noxious products and will improve burning qualities of the solid products. Preliminary experiments showed that EBC 104 coal catalyzes the formation of hydroperoxides in safflower oil and that more sulfur is extracted from the treated than untreated coal. During this first quarter the requirement of an added photosensitizer has been eliminated, the catalytic effect of coal has been confirmed, and the existence of a complex set of reactions revealed. These reactions between the oxygen, oil, hydroperoxides, and coal are hydroperoxide formation, which is catalyzed by the coal surface and by heat, an unknown coal-hydroperoxide reaction, and oil polymerization. Additionally, diffusion phenomena must be playing a role because oil polymerization occurs, but the importance of diffusion is difficult to assess because less polymerization occurs when coal is present. The first task has been completed and we are now ready to determine the ability of linseed oil hydroperoxides to oxidize organic sulfur in EBC 108 coal.

    The United States produced just over 1 billion short tons of coal in 1992, 0.4 percent more than in 1991. Most of the 4-million-short-ton increase in coal production occurred west of the Mississippi River, where a record level of 408 million short tons of coal was produced. The amount of coal received by domestic consumers in 1992 totaled 887 million short tons. This was 7 million short tons more than in 1991, primarily due to increased coal demand from electric utilities. The average price of delivered coal to each sector declined by about 2 percent. Coal consumption in 1992 was 893 million short tons, only 1 percent higher than in 1991, due primarily to a 1-percent increase in consumption at electric utility plants. Consumer coal stocks at the end of 1992 were 163 million short tons, a decrease of 3 percent from the level at the end of 1991, and the lowest year-end level since 1989. US coal exports fell 6 percent from the 1991 level to 103 million short tons in 1992. Less coal was exported to markets in Europe, Asia, and South America, but coal exports to Canada increased 4 million short tons.

    The objective of this program is to examine slags formed as a result of firing coals with varying concentration levels, size distribution, and orientation of pyrite with regard to mineral matter in the coal in a laboratory furnace. The program tasks are: (1) selection of eight candidate coals; (2) chemical characterization of the coal samples and identification of the pyrite size, distribution, and orientation with respect to other mineral matter and concentration levels; (3) testing of the candidate coals in a laboratory furnace; (4) chemical and physical characterization of the slag and fly ash samples created by the impurities in the coal sample; (5) influence of coal beneficiation on furnace slagging; and (6) analysis of data and identification of parameters influencing the contribution of pyrite to slagging problems. Washing of the Upper Freeport coal from Indiana County, Pennsylvania, was completed by the last quarter of 1983. The washed product was characterized for mineral content, and a combustion test was performed. Kentucky No. 9 from Henderson County, Kentucky, selected as the sixth coal to be investigated, was characterized using size and gravity fractionation techniques and was combusted in the laboratory furnace to evaluate its slagging and fouling potential. The remaining two coals to be characterized and combusted were identified as Illinois No. 5 and Lower Kittanning from Clarion County, Pennsylvania. 80 figures, 27 tables.

    In the last report, it was shown that when lignin is added to coal, the rate of coal depolymerization is enhanced. The results,-reported were based upon a number of experiments conducted for the following three reasons: (i) to generate enough quantities of liquid products so that their stability in various environments can be ascertained, (ii) to closely characterize the reaction products, so that individual atomic mass balances can be performed, and (iii) to determine the reproducibility of the experiments conducted. The stability of liquid products was characterized by determining their solubility in pentane and benzene. Exposure of the coal- and coal+lignin-derived liquids to air at 40 and 80{degrees}C led to a decrease in the pentane-soluble and asphaltene fractions with a concomitant enhancement in the benzene insoluble fraction. However, relatively no degradation was observed for the liquid samples exposed to an inert (N{sub 2}) atmosphere. Preliminary data show that the coal+lignin-derived liquids are more stable than that obtained by coal liquefaction. In this quarterly report, individual atomic mass balances on various experiments conducted with coal, lignin and coal+lignin mixtures are also reported. Although the overall mass recoveries of 95--98% of the total mass charged to the reactor were obtained, the atomic mass balance data are somewhat difficult to interpret due to the possible incorporation of tetralin (solvent) in the reaction products.

    Resinite is a naturally occurring substance found in coal and derived from original plant resins. It is ubiquitous in North American coals. It makes up one to four percent by volume of most Illinois coals. It has been commercially exploited in the western USA for use in adhesives, varnishes and thermal setting inks. The overall objective of this project is to compare the properties of the resinite contained in Illinois Basin coals to resinite being commercially exploited in the western United States, and to recover the resinite from Illinois coals by microbubble column floatation techniques. The significance of this study is that it has the potential to show the way to recover a valuable chemical, resinite, from coal using only physical processing techniques. The value of the resinite at $1.00/kg or $0.50/lb makes it about fifty times more valuable than steam coal. The removal of resinite from coal does not decrease the value of the remaining coal in any way. The unique aspects are that: (1) it is the first examination of the resinite recovery potential of Illinois coal, (2) it integrates the latest characterization techniques such as density Gradient centrifugation, microspectrofluorometry, and gas chromatography- mass spectrometry, and (3) it uses microbubble column flotation to determine the resinite recovery potential. During this quarter samples were obtained, information from both the databases of both the Illinois State Geological Survey (ISGS) and the Pennsylvania State University (PSU) was obtained and evaluated, and EBCSP samples from the Herrin No. 6, the Springfield No. 5 and the Colchester No. 2 seams were analyzed petrographically and the resinites in these samples were characterized by fluorescence spectral analysis.

    Six runs on the bench unit were successfully completed this quarter. The runs covered twenty five different operating conditions and yield periods, and involved 336 hours of operation. In the bench unit, increased temperature of first stage operation (410{degree}C) and direct addition of the powdered solid sodium aluminate to the feed as first stage catalyst improved both coal and carbon monoxide conversion. To achieve 90%+ overall coal conversion, temperatures of 430{degree}C+ were required in the second stage. Oil yields (pentane soluble liquid product) in excess of 65 wt % based on MAF Black Thunder coal, were achieved both with iron oxide/dimethyl disulfide and ammonium molybdate/carbon disulfide second stage catalysts. C{sub l}-C{sub 3} hydrogen gas yields were modest, generally 7-8 wt % on MAF coal, and overall hydrogen consumption (including first stage shift hydrogen) was in the order of 7-8 wt % on MAF coal. The ammonium molybdate catalyst system appeared to give slightly higher oil yields and hydrogen consumption, as was expected, but the differences may not be significant.

During this second quarter working with IBC-108 coal (2.3% organic S. 0.4% pyrite S), the effects of different ratios of oil:coal, different extraction solvents, and different temperatures were examined. A new pretreatment which combines alkali with linseed oil was discovered. Best organic sulfur removal is approximately 26% using alkali pretreatment combined with linseed oil at 1OO{degree}C. BTU loses can be kept to a minimum of 3% with proper use of solvents.

    The objectives of this quarter of study on the co-firing of high sulfur coal with refuse derived fuels project were two-fold. First, the effect of S0{sub 2} on the formation of chlorine during combustion processes was examined. To simulate the conditions used in the AFBC system, experiments were conducted in a quartz tube in an electrically heated furnace. The principle analytical technique used for identification of the products from this study was GC/MS. The evolved gas was trapped by an absorbent and analyzed with a GC/MS system. The preliminary results indicate an inhibiting effect of S0{sub 2} on the Deacon Reaction. Secondly, information on the evolution of chlorine, sulfur and organic compounds from coals 95031 and 95011 were studied with the AFBC system. 2 figs., 1 tab.

    Low severity coal liquefaction allows for solubilization of coal with reduced gas make. These lower severity conditions may result in some selective bond rupture. Promotion of coal solubilization through hydrogen transfer using highly active and effective hydrogen donors is the objective of this study. The highly effective donors being tested are cyclic olefins. Representative cyclic olefins are isotetralin, which is 1,4,5,8-tetrahydronaphthalene, and 1,4,5,8,9,10-hexahydroanthracene. These compounds are hydroaromatics without aromatic rings and have been shown to be highly effective donors. The objective of the work performed in this study during this quarter was to evaluate reaction parameters for low severity liquefaction reactions using the cyclic olefin, hexahydroanthracene, and the aromatic, anthracene. These model compounds were reacted under a variety of conditions to evaluate their reactivity without coal. The reactions were performed under both thermal and catalytic conditions. Finely divided catalysts from different molybdenum precursors were used to determine their activity in promoting hydrogenation and hydrogen transfer at low severity conditions. The catalysts used were Molyvan L, sulfurized oxymolybdenum dithiocarbamate, molybdenum naphthenate, and Molyvan 822, organo molybdenum dithiocarbamate.

    Research Triangle Institute (RTI), Eastman Chemical Company, and Bechtel collectively are developing a novel process for the synthesis of methyl methacrylate (MMA) from coal-derived syngas that consists of three steps of synthesis of a propionate, its condensation with formaldehyde, and esterification of resulting methacrylic acid (MAA) with methanol to produce MMA. Over the last quarter, Eastman developed two new processes which have resulted in two new invention reports. One process deals with carbonylation of benzyl ether which represents a model for coal liquefaction and the second focuses on the acceleration of carbonylation rates for propionic acid synthesis, via use of polar aprotic solvents. These two inventions are major improvements in the novel Mo-catalyzed homogeneous process for propionic acid synthesis technology, developed by Eastman. Over the last quarter, RTI completed three reaction cycles and two regeneration cycles as a part of long-term reaction regeneration cycle study on a 10% Nb{sub 2}O{sub 5}/Si0{sub 2} catalyst, for vapor phase condensation reaction of formaldehyde with propionic acid.

    A key objective is to determine the most desirable ways of integrating coal liquefaction liquids into existing petroleum refineries to produce transportation fuels meeting current and future, e.g. year 2000, Clean Air Act Amendment (CAAA) standards. An intregral part of the above objectives is to test the fuels or blends produced and compare them with established ASTM fuels. The comparison will include engine tests to ascertain compliance of the fuels produced with CAAA and other applicable fuel quality and performance standards. The final part of the project includes a detailed economic evaluation of the cost of processing the coal liquids to their optimum products. The cost analyses is for the incremental processing cost; in other words, the feed is priced at zero dollars. The study reflects costs for operations using state of the art refinery technology; no capital costs for building new refineries is considered. Some modifications to the existing refinery may be required. Economy of scale dictates the minimum amount of feedstock that should be processed. To enhance management of the study, the work has been divided into two parts, the Basic Program and Option 1. The objectives of the Basic Program are to: characterize the coal liquids; develop, an optimized refinery configuration for processing indirect and direct coal liquids; and develop a LP refinery model with the Process Industry Modeling System (PICS) software. The objectives of Option 1 are to: confirm the validity of the optimization work of the Basic Program; produce large quantities of liquid transportation fuel blending stocks; conduct engine emission tests; and determine the value and the processing costs of the coal liquids. The major efforts conducted during the first quarter of 1994 were in the areas of: subcontract preparation and negotiation; and linear programming modeling.

    It is the objective of this project to isolate the asphaltene and preasphaltene fractions from coal liquids from a number of liquefaction processes. These processes consist of in general: catalytic hydrogenation, staged pyrolysis and solvent refining. These asphaltene fractions may be further separated by both gradient elution through column chromatography, and molecular size distribution through gel permeation chromatography. Those coal-derived asphaltene and preasphaltene fractions will be investigated by various chemical and physical methods for characterization of their structures. After the parameters are obtained, these parameters will be correlated with the refining and conversion variables which control a given type of liquefaction process. The effects of asphaltene in catalysis, ash or metal removal, desulfurization and denitrification will also be correlated. It is anticipated that understanding the role of asphaltenes in liquefaction processes will enable engineers to both improve existing processes, and to make recommendations for operational changes in planned liquefaction units in the United States. The objective of Phase 1 was to complete the isolation and separation of coal liquid fractions and to initiate their characterization. The objective of Phase 2 is to continue the characterization of coal asphaltenes and other coal liquid fractions by use of physical and instrumental methods. The structural parameters obtained will be used to postulate hypothetical average structures for coal liquid fractions. The objective of Phase 3 is to concentrate on the characterization of the preasphaltene (benzene insoluble fraction) of coal liquid fraction by the available physical and chemical methods to obtain a number of structural parameters.

Activities included the operation and modification of the Solvent Refined Coal Pilot Plant at Fort Lewis, Washington; the Process Development Unit P-99 at Harmarville, Pennsylvania; and research at Merriam Laboratory in Merriam, Kansas. The Pilot Plant processed Powhatan No. 5 Coal in the SRC-II mode of operation studying the effect of coal particle size and system temperature on coal slurry blending and the effect of carbon monoxide concentration in the reaction feed gas on process yields. January and February were spent completing installation of a fourth High Pressure Separator on Process Development Unit P-99 to better simulate operating conditions for the proposed Demonstration Plant. During March, one run was completed at P-99 feeding Pittsburgh Seam Coal from the Powhatan No. 5 Mine. Merriam investigations included a study of the effect of iron containing additives on SRC-I operation, the addition of carbon monoxide to the feed gas, utilization of a hydrogenated solvent (Cresap process solvent) in the SRC-I mode under both normal and short residence time operating conditions, and development of a simulated distillation technique to determine the entire boiling range distribution of product oils.

    Organic sulfur is removed from coals by treatment with aqueous base, air, and vegetable oils with minimal loss of BTU. Such results were revealed during exploratory experiments on an ICCI funded project to remove organic sulfur from Illinois coals with hydroperoxides of vegetable oils. In fact, prewashing IBC-108 coal with dilute alkali prior to treating with linseed oil and air results in 26% removal of sulfur. This new method is being investigated by treating coals with alkali, impregnating coals with polyunsaturated oils, converting the oils to their hydroperoxides, and heating. Since these oils are relatively inexpensive and easily applied, this project could lead to a cost effective method for removing organic sulfur from coals. During the first quarter the selection of base fro pretreatment and extraction was completed. NaOH is better than NH{sub 4}OH for the pretreatment and Na{sub 2}CO{sub 3} is better than NaOH for the oil extraction. During the second quarter the effectiveness of linseed oil and NaOH for sulfur removal from IBC-108 coal was further tested by pretreating the coal with two base concentrations at four different times followed by treatment with linseed oil at 125{degrees}C for three different times and finally washing with 5% Na{sub 2}CO{sub 3} and methanol. During this third quarter more experimental parameters were systematically varied in order to study the effectiveness of linseed oil and NaOH for sulfur removal from IBC- 108 coal.

SRC-I turnaround activities at the Fort Lewis Pilot Plant and several other problems delayed successful startup until April 11. Slurry was injected to the Lummus Deashing Unit for the first time April 12. After approximately eight days, slurry feed was diverted because of indications that solids were accumulating in the settler vessel. The Fort Lewis Pilot Plant was shut down from April 28 to May 12, 1979, while the Lummus Unit settler vessel was hydroblasted. Cleaning of the settler vessel was complete May 10. Modifications to the unit were nearly complete at the end of the reporting period. Slurry feed to the Lummus Unit was reestablished June 15. To date, continuous production of specification product at design rates has not been achieved. One material balance run, MBR 79-1, was completed using Kentucky No. 9/14 coal at proposed design conditions for the SRC-I Demonstration Plant. Process Development Unit P-99 was on-stream for all of the second quarter of 1979, with the exception of a two-week scheduled turn-around. Six different run conditions were tested feeding Pittsburgh Seam coal from the Powhatan No. 5 Mine.

    The primary objective of this ``CAT`` (Coal Air Turbine) project is to complete a conceptual design of this unique new combination of existing technology with cost estimates to show that the CAT system offers the economic incentive with low technical risk for a plant to be built which will demonstrate its viability. The technologies involved in the components of a CAT plant are proven, and the integration of the components into a complete plant is the only new developmental activity involved. Industry and the Federal General Services Administration (GSA), require the demonstration of a commercial plant before the viability of a new concept is accepted. To satisfy this requirement the construction of a plant of commercially viable size in excess of 15 MW if cogeneration and above 30 MW if all power, is proposed. This plant will produce economical power and heat for the owner. The plant will operate for a full commercial life and continue as an operating demonstration of the viability of the technology, gathering long term life and maintenance data, all adding to the credibility of the concept. The major components of CAT plants are an air turbine, a heater of compressed air, a coal combustion system, means to recover waste heat and a steam turbine when appropriate. The plant burns raw coal in a fluid bed at atmospheric pressure. The air turbine operates on clean compressed air heated inside tubes immersed in the fluid bed. Progress during the fifth quarter is described.

    Work this quarter focused on staged liquefaction. The effect of residence time on conversion in single pass experiments was found to be quite different for the subbituminous Belle Ayr Mine and bituminous Illinois No. 6 coals studied. With bituminous coal, conversion to soluble material is quite high and the limit of conversion is approached in only a few minutes. With a subbituminous coal, however, conversion is much lower and the limit of conversion is approached much more slowly. Short contact time (SCT) dissolution of Belle Ayr coal was studied as a possible first stage in a two-stage process. Conversion, hydrocarbon gas yield and hydrogen consumption were increased as residence time or temperature were increased. Conversion was also significantly increased by partial slurry recycle. Pyrite was found to be the most effective slurry catalyst for increasing conversion, followed by ammonium molybdate emulsion and finally nickel-molybdenum on alumina. Illinois No. 6 coal was liquefied in two stages. Conditions in the first stage dissolution were varied to determine the effect on upgradability in the second stage. An SCT (6 minute) coal dissolution stage is preferred over one at 30 minutes because hydrocarbon gas yield was much lower while overall oil yields for the combined dissolution and upgrading stages were nearly the same. Use of a NiMo/Al/sub 2/O/sub 3/ catalyst in a trickle-bed second stage resulted in a higher oil yield and lower product heteroatom content than use of the same catalyst in the slurry phase. The total oil yield was lower with a pyrite slurry catalyst than with a NiMo/Al/sub 2/O/sub 3/ slurry catalyst. With Belle Ayr coal and added pyrite, there was no change in total oil yield, conversion or product quality brought about by adding an 8-minute first stage at 450/sup 0/C (842/sup 0/F) to a 2-hour second stage operated at 420/sup 0/C (788/sup 0/F). 39 figures, 12 tables.

  6. Coal reserves are plentiful but unevenly distributed

    There is plenty of coal in Canada. The estimated coal resources are more than 360,000,000,000 tons with most of this coal located in the western provinces. The estimated minable coal reserves are more than 16,000,000,000 tons and the recoverable coal is more than 6,000,000,000 tons. The latter figure reflects the lack of current development in many coalfields. Very recent and current exploration for coal as well as for oil and gas has indicated coal resources in addition to those already estimated. Incremental additions to coal resources can be expected in northern and eastern Canada. In the latter region, more than 85 percent of the total coal resources are beneath the ocean. The main coal deposits in western Canada are very far from the large industrial markets of Ontario and Quebec. They are closer, yet still quite distant, from export ports on the Pacific Ocean. Current efforts to improve coal transportation are expected to decrease the disadvantages of the unfavorable location of the western coalfields. This will increase the coal reserves in the region as further exploration will surely follow.

    A potentially new use for Illinois coal is its use as a fuel injected into a blast furnace to produce molten iron as the first step in steel production. Because of its increasing cost and decreasing availability, metallurgical coke is now being replaced by coal injected at the tuyere area of the furnace where the blast air enters. The purpose of this study is to evaluate the combustion of coal during the blast furnace injection process and to delineate the optimum properties of the feed coal. This proposal is a follow-up to one funded for the 1992--1993 period. It is intended to complete the study already underway with the Armco Inc. Steel Company and to initiate a new cooperative study along somewhat similar lines with the Inland Steel Company. The results of this study will lead to the development of a testing and evaluation protocol that will give a unique and much needed understanding of the behavior of coal in the injection process and prove the potential of Illinois coals for such use. During this quarter a sample of the feed coal that is being used for injection into the No. 7 Blast Furnace of Inland Steel has been analyzed petrographically and compared to both the Herrin No. 6 coal and Armco feed coal. Additional characterization is underway and an advanced program of pyrolysis and reactivity testing has been initiated.

    This is the eleventh Quarterly Technical Progress Report under DOE Contract DE-AC22-89PC89883. Major topics reported are: (1) The results of a study designed to determine the effects of the conditions employed at the Wilsonville slurry preheater vessel on coal conversion is described. (2) Stable carbon isotope ratios were determined and used to source the carbon of three product samples from Period 49 of UOP bench-scale coprocessing Run 37. The results from this coprocessing run agree with the general trends observed in other coprocessing runs that we have studied. (3) Microautoclave tests and chemical analyses were performed to ``calibrate`` the reactivity of the standard coal used for determining donor solvent quality of process oils in this contract. (4) Several aspects of Wilsonville Close-Coupled Integrated Two-Stage Liquefaction (CC-ITSL) resid conversion kinetics were investigated; results are presented. Error limits associated with calculations of deactivation rate constants previously reported for Runs 258 and 261 are revised and discussed. A new procedure is described that relates the conversions of 850{degrees}F{sup +} , 1050{degrees}F{sup +}, and 850 {times} 1050{degrees}F material. Resid conversions and kinetic constants previously reported for Run 260 were incorrect; corrected data and discussion are found in Appendix I of this report.

    The quality characteristics of eastern Kentucky coal beds vary both spatially and stratigraphically. Average total sulfur contents are lowest, and calorific values highest, in the Big Sandy and Upper Cumberland Reserve Districts. Average coal thickness is greatest in these two districts as well. Conversely, the thinnest coal with the highest total sulfur content, and lowest calorific value, on average, occurs in the Princess and Southwest Reserve Districts. Several Title III trace elements, notably arsenic, cadmium, lead, mercury, and nickel, mirror this distribution (lower average concentrations in the Big Sandy and Upper Cumberland Districts, higher average concentrations in the Princess and Southwest Districts), probably because these elements are primarily associated with sulfide minerals in coal. Ash yields and total sulfur contents are observed to increase in a stratigraphically older to younger direction. Several Title III elements, notably cadmium, chromium, lead, and selenium follow this trend, with average concentrations being higher in younger coals. Average chlorine concentration shows a reciprocal distribution, being more abundant in older coals. Some elements, such as arsenic, manganese, mercury, cobalt, and, to a lesser extent, phosphorus show concentration spikes in coal beds directly above, or below, major marine zones. With a few exceptions, average Title III trace element concentrations for eastern Kentucky coals are comparable with element distributions in other Appalachian coal-producing states.

    Bechtel, with Southwest Research Institute, Amoco Oil R&D, and the M. W. Kellogg Co. as subcontractors, initiated a study on November 1, 1993, for the U.S. Department of Energy`s (DOE`s) Pittsburgh Energy Technology Center (PETC) to determine the most cost effective and suitable combination of existing petroleum refinery processes needed to make specification transportation fuels or blending stocks, from direct and indirect coal liquefaction product liquids. This 47-month study, with an approved budget of $4.4 million dollars, is being performed under DOE Contract Number DE-AC22-93PC91029. A key objective is to determine the most desirable ways of integrating coal liquefaction liquids into existing petroleum refineries to produce transportation fuels meeting current and future, e.g. year 2000, Clean Air Act Amendment (CAAA) standards. An integral part of the above objectives is to test the fuels or blends produced and compare them with established ASTM fuels. The comparison will include engine tests to ascertain compliance of the fuels produced with CAAA and other applicable fuel quality and performance standards. The final part of the project includes a detailed economic evaluation of the cost of processing the coal liquids to their optimum products. The cost analyses is for the incremental processing cost; in other words, the feed is priced at zero dollars. The study reflects costs for operations using state of the art refinery technology; no capital costs for building new refineries is considered. Some modifications to the existing refinery may be required. Economy of scale dictates the minimum amount of feedstock that should be processed. The major efforts conducted during the third quarter of 1996 were in the areas of hydrotreating production runs and FCC production run. 3 figs., 8 tabs.

    The objectives of this project are to support the DOE direct coal liquefaction process development program and to improve the useful application of analytical chemistry to direct coal liquefaction process development. Independent analyses by well-established methods will be obtained of samples produced in direct coal liquefaction processes under evaluation by DOE. Additionally, analytical instruments and techniques which are currently underutilized for the purpose of examining coal-derived samples will be evaluated. The data obtained from this study will be used to help guide current process development and to develop an improved data base on coal and coal liquids properties. A sample bank will be established and maintained for use in this project and will be available for use by other researchers. The reactivity of the non-distillable resids toward hydrocracking at liquefaction conditions (i.e., resid reactivity) will be examined. From the literature and data experimentally obtained, a mathematical kinetic model of resid conversion will be constructed. It is anticipated that such a model will provide insights useful for improving process performance and thus the economics of direct coal liquefaction. During this quarter, analyses were completed on 65 process samples from representative periods of HRI Run POC-2 in which coal, coal/plastics, and coal/rubber were the feedstocks. A sample of the oil phase of the oil/water separator from HRI Run POC-1 was analyzed to determine the types and concentrations of phenolic compounds. Chemical analyses and microautoclave tests were performed to monitor the oxidation and measure the reactivity of the standard coal (Old Ben Mine No. 1) which has been used for the last six years to determine solvent quality of process oils analyzed in this and previous DOE contracts.

Because of its increasing cost and decreasing availability, metallurgical coke is now being replaced by coal injected at the tuyere area of the furnace where the blast air enters. The purpose of this study is to evaluate the combustion of Illinois coal in the blast furnace injection process in a new and unique pilot plant test facility. This investigation is significant to the use of Illinois coal in that the limited research to date suggests that coals of low fluidity and moderate to high sulfur and chlorine contents are suitable feedstocks for blast furnace injection. This study is unique in that it is the first North American effort to directly determine the nature of the combustion of coal injected into a blast furnace. This proposal is a follow-up to one funded for the 1993--94 period. It is intended to complete the study already underway with the Armco and Inland steel companies and to demonstrate quantitatively the suitability of both the Herrin No. 6 and Springfield No. 5 coals for blast furnace injection. The main feature of the current work is the testing of Illinois coals at CANMET`s (Canadian Centre for Mineral and Energy Technology) pilot plant coal combustion facility. This facility simulates blowpipe-tuyere conditions in an operating blast furnace, including blast temperature (900{degrees}C), flow pattern (hot velocity 200 m/s), geometry, gas composition, coal injection velocity (34 m/s) and residence time (20 ms). The facility is fully instrumented to measure air flow rate, air temperature, temperature in the reactor, wall temperature, preheater coil temperature and flue gas analysis. During this quarter there were two major accomplishments.

Work on the CFFF progressed with only minor problems. Total construction activity for all site work presently awarded is nearly 98% complete. Water analysis shows that Woods Reservoir baseline conditions are within EPA or Tennessee drinking water standards. For the primary combustor, the vitiation heater and primary combustor fabrication drawings were completed and the nozzle design was completed. The drum module for the radiant slagging furnace was awarded. On the MHD Power Generator, development continued in several areas of advanced analysis including development of time-dependent models for use with the one-dimensional code. For seed regeneration, the tentative determination is that the Tomlinson Tampella is the most economically viable method. With regard to capped electrode erosion, investigations have shown that the major degradation of the cladding still present is at the leading edge of the capped anode. To alleviate this, plans are to hot work the noble metal in the bending operation. In resolving another problem, a system employing the modified line-reversal method has been assembled and successfully tested to measure absolute plasma temperatures.

    The main goal of this project is to develop a bench-scale procedure to design and fabricate advanced brake and structural composite materials from Illinois coal combustion residues. During the first two quarters of the project, the thrust of the work directed towards characterizing the various coal combustion residues and FGD residue, i.e., scrubber sludge. Scanning electron microscopy (SEM), differential scanning calorimetry (DSC), differential thermal analysis (DTA), and transmission-Fourier transform infrared (FTIR) were conducted on PCC fly ash (Baldwin), FBC fly ash (ADK unit l-6), FBC fly ash (S.I. coal), FBC spent bed ash (ADM, unit l-6), bottom ash, and scrubber sludge (CWLP) residues to characterize their geometrical shapes, mineral phases, and thermal stability. Our spectroscopic results indicate that the scrubber sludge is mainly composed of a gypsum-like phase whose lattice structure is different from the lattice structure of conventional gypsum, and sludge does not contain hannebachite (CaSO{sub 3}.0.5H{sub 2}O) phase. Our attempts to fabricate brake frictional shoes, in the form of 1.25 inch disks, from PCC fly ash, FBC spent bed ash, scrubber sludge, coal char, iron particles, and coal tar were successful. Based on the experience gained and microscopic analyses, we have now upscaled our procedures to fabricate 2.5 inch diameter disk,- from coal combustion residues. This has been achieved. The SEM and Young`s modulus analyses of brake composites fabricated at 400 psi < Pressure < 2200 psi suggest pressure has a strong influence on the particle packing and the filling of interstices in our composites. Also, these results along with mechanical behavior of the fabricated disks lead us to believe that the combination of surface altered PCC fly ash and scrubber sludge particles, together ed ash particles are ideal for our composite materials.

    1993-08-01

    The effect of weathering (oxidation and dehydration upon exposure to air) on the molecular accessibility of potential catalysts was studied by the EPR spin probe technique. Fresh samples of all 8 APCS coals were exposed to air for periods up to 36 days. Weathering produced significant effects on the retention of spin probes in most of the APCS coals under 91 % carbon (dmmf). It was determined that the lower ranked coal (Beulah Zap and Wyodak) under went a structural collapse which precluded retention of even spin probe VIII. However, medium ranked coals exhibited improved retention upon weathering when swelled in toluene. Swelling with pyridine opened up small pores for 81--86% carbon which is not observed for swelling with toluene. Changes in coal structure were successfully followed by the EPR spin probe method. A detailed analysis of the data collected from the swelling of coals oxidized in a moisture free environment was completed to differentiate between weathering and oxidation. Eight vacuum dried APCS coals were oxidized in an enclosed, pure oxygen, moisture free environment, and the effects of oxidation alone on coal structure were studied by the intercalation of EPR spin probes. The data shows a factor of 5 increase in spin probe retention for some coals oxidized in O{sub 2} versus air., suggesting a large increase in oxidized material. Particular care was taken during the swelling procedures to avoid exposure of the coal samples to air or moisture. EPR spectra were then obtained for these 300 samples.

    This report describes the progress made during this reporting period of a two year project to demonstrate that the air pollution from a traveling-grate stoker being used to heat water at a central heating plant in Krakow, Poland can be reduced significantly by (1) substituting the unwashed, unsized coal currently being used with a mechanically cleaned, double-sized stoker fuel and by (2) optimizing the operating parameters of the stoker. It is anticipated that these improvements will prove to be cost-effective and hence will be adopted by the other central heating plants in Krakow and ideally, throughout Eastern European cities where coal continues to be the primary source of fuel. EFH Coal Company has formed a partnership with two Polish institutions -- MPEC, a central heating company in Krakow, and Naftokrak-Naftobudowa, preparation plant designers and fabricators-for the execution of this effort. Five potential candidate sources have been located and contracts for coal deliveries should be executed early next quarter. TInitial delays in formalizing the EFH/Polish Partners agreement delayed finalizing the coal supply contracts and hence, precluded collecting the Polish coal samples for characterization and combustion performance studies. Work on this Task will be initialed next quarter after the raw coal supply contracts are executed. A conceptual design for a plant to wash 25mm x 0 raw coal fines at a need rate of 300 mtph was completed. This plant will receive raw coals ranging in ash content from 20 to 30 percent and produce a compliance coal containing about 1 percent ash, 0.8 percent sulfur and 27, 840 KJ/kg (12,000 Btu/lb). A heavy-media cyclone will be used to wash the 20mm x 1mm stoker coal. Discussions with financial institutions regarding the cost of producing a quality stoker coal in Poland and A for identifying sources of private capital to help cost share the project continued.

    The main goal of this project is to develop a bench-scale procedure to design and fabricate advanced brake and structural composite materials from Illinois coal combustion residues. Scanning electron microscopy (SEM), differential scanning calorimetry (DSC), differential thermal analysis (DTA), and transmission-Fourier transform infrared (FTIR) were conducted on PCC fly ash (Baldwin), FBC fly ash (ADM unit1-6), FBC fly ash (S.I. coal), FBC spent bed ash (ADM unit1-6), bottom ash, and scrubber sludge (CWLP) residues to characterize their geometrical shapes, mineral phases, and thermal stability. Our spectroscopic results indicate that the scrubber sludge is mainly composed of a gypsum-like phase whose lattice structure is different from the lattice structure of conventional gypsum, and sludge does not contain hannebachite (CaSO{sub 3}0.5H{sub 2}O) phase. In the second and third quarters the focus of research has been on developing protocols for the formation of advanced brake composites and structural composites. Our attempts to fabricate brake frictional shoes, in the form of 1.25 inch disks, from PCC fly ash, FBC spent bed ash, scrubber sludge, coal char, iron particles, and coal tar were successful. Based on the experience gained and microscopic analyses, we have now upscaled our procedures to fabricate 2.5 inch diameter disks from coal combustion residues. The SEM and Young`s modulus analyses of brake composites fabricated at 400 psi < Pressure < 2200 psi suggest pressure has a strong influence on the particle packing and the filling of interstices in our composites.

    This quarterly report discusses the technical progress of an Innovative Clean Coal Technology (ICCT) demonstration being conducted at Georgia Power Company`s Plant Hammond Unit 4 located near Rome, Georgia. The primary goal of this project is the characterization of the low NO{sub x} combustion equipment through the collection and analysis of long-term emissions data. A target of achieving fifty percent NO{sub x} reduction using combustion modifications has been established for the project. The project provides a stepwise retrofit of an advanced overfire air (AOFA) system followed by low NO{sub x} burners (LNB). During each test phase of the project, diagnostic, performance, long-term, and verification testing will be performed. These tests are used to quantify the NO{sub x} reductions of each technology and evaluate the effects of those reductions on other combustion parameters such as particulate characteristics and boiler efficiency. During this quarter, long-term testing of the LNB + AOFA configuration continued and no parametric testing was performed. Further full-load optimization of the LNB + AOFA system began on March 30, 1993. Following completion of this optimization, comprehensive testing in this configuration will be performed including diagnostic, performance, verification, long-term, and chemical emissions testing. These tests are scheduled to start in May 1993 and continue through August 1993. Preliminary engineering and procurement are progressing on the Advanced Low NOx Digital Controls scope addition to the wall-fired project. The primary activities during this quarter include (1) refinement of the input/output lists, (2) procurement of the distributed digital control system, (3) configuration training, and (4) revision of schedule to accommodate project approval cycle and change in unit outage dates.

    A potentially new use for Illinois coal is its use as a fuel injected into a blast furnace to produce molten iron as the first step in steel production. Because of its increasing cost and decreasing availability, metallurgical coke is now being replaced by coal injected at the tuyere area of the furnace where the blast air enters. The purpose of this study is to evaluate the combustion of coal during the blast furnace injection process and to delineate the optimum properties of the feed coal. This investigation is significant to the use of Illinois coal in that the limited research to date suggests that coals of low fluidity and moderate to high sulfur and chlorine contents are suitable feedstocks for blast furnace injection. This study is unique in that it will be the first North American effort to directly determine the nature of the combustion of coal injected into a blast furnace. This proposal is a follow-up to one funded for the 1992--1993 period. It is intended to complete the study already underway with the Armco Inc. steel company and to initiate a new cooperative study along somewhat similar lines with the Inland Steel Company. The results of this study will lead to the development of a testing and evaluation protocol that will give a unique and much needed understanding of the behavior of coal in the injection process and prove the potential of Illinois coals f or such use.

    The objective of this research is to optimize the design and operation of the bench scale batch reactor (SCTBR) f or coal liquefaction at short contact times (0.01 to 10 minutes or longer). Additional objectives are to study the kinetics of direct coal liquefaction particularly at short reaction times, and to investigate the role of the organic oxygen components of coal and their reaction pathways during liquefaction. Many of those objectives have already been achieved and others are still in progress. This quarterly report covers further progress toward those objectives.

    This research project is for the development of a technical and economical feasible process for drying and stability fine particles of high-moisture subbituminous coal. Research conducted in this quarter focused upon thermogravimetric analysis (TGA) of both feed coals; continuation of the bench-scale IFB drying experiments; and initiation of the characterization of the products from the bench-scale drying experiments to determine their moisture reabsorption, dustiness, and spontaneous ignition properties. Thirty 4-hr and six 12-hr bench-scale IFB drying tests were conducted this quarter making a total of forty-one 4-hr (19 using Eagle Butte feed coal and 22 using Usibelli feed coal) and six 12-hr (3 using each feed coal) tests conducted thus far. IFB reactor slopes of 3, 6, 9, 12, and 15 degrees were investigated for each feed coal. During the tests using Eagle Butte coal, gas-to-solids ratios ranging from approximately 0.7 to 9.7 lb/lb (kg/kg) and average IFB reactor temperatures ranging from approximately 370 to 700/degree/F (188 to 371/degree/C) were tested. 5 refs., 41 figs., 7 tabs.

    This report summarizes the progress of the Exploratory Research on Solvent Refined Coal Liquefaction project by The Pittsburgh and Midway Coal Mining Company's Merriam Laboratory for the period April 1, 1979 through June 30, 1979. Experimental work included a number of short residence time runs, but discussion of that work has been delayed until a later report. Experimental work reported focuses on an investigation of the decline in solvent quality experienced by the Wilsonville Pilot Plant during runs in support of the SRC I Demonstration Plant. A four run series was initiated with Wilsonville solvent; both the coal used at Wilsonville (Kentucky 6/11 - Pyro Mine) and Kentucky 9/14 coal from the Colonial Mine were used. The effect of pyrite addition to the Pyro Mine coal was investigated. No solvent quality or coking problems were experienced in the Merriam runs. Significant changes in solvent composition were apparent and equilibrated solvent samples were returned to Wilsonville for solvent quality testing.

    The Mulled Coal process was developed as a means of overcoming the adverse handling characteristics of wet fine coal without thermal drying. The process involves the addition of a low cost, harmless reagent to wet fine coal using off-the-shelf mixing equipment. The objectives of this project are to demonstrate that: The Mulled Coal process, which has been proven to work on a wide range of wet fine coals at bench scale, will work equally well on a continuous basis, producing consistent quality at a convincing rate of production in a commercial coal preparation plant. The wet product from a fine coal cleaning circuit can be converted to a solid fuel form for ease of handling and cost savings in storage and rail car transportation. A wet fine coal product thus converted to a solid fuel form, can be stored, shipped, and burned with conventional fuel handling, transportation, and combustion systems. During this third quarter of the contract period, activities were underway under Tasks 2 and 3. Sufficient characterization of the feedstock coal options at the Chetopa Plant was conducted and mulling characteristics determined to enable a decision to be made regarding the feedstock selection. It was decided that the froth concentrate will be the feedstock wet fine coal used for the project. On that basis, activities in the areas of design and procurement were initiated.

    The porosity and pore size distribution of coals determine many of their properties, from gas release to their behavior on carbonization, and yet most methods of determining pore size distribution can only examine a restricted size range. Even then, only accessible pores can be investigated with these methods. Small-angle neutron scattering (SANS) and ultra small-angle neutron scattering (USANS) are increasingly used to characterize the size distribution of all of the pores non-destructively. Here we have used USANS/SANS to examine 24 well-characterized bituminous and subbituminous coals: three from the eastern US, two from Poland, one from New Zealand and the rest from the Sydney and Bowen Basins in Eastern Australia, and determined the relationships of the scattering intensity corresponding to different pore sizes with other coal properties. The range of pore radii examinable with these techniques is 2.5 nm to 7 {micro}m. We confirm that there is a wide range of pore sizes in coal. The pore size distribution was found to be strongly affected by both rank and type (expressed as either hydrogen or vitrinite content) in the size range 250 nm to 7 {micro}m and 5 to 10 nm, but weakly in intermediate regions. The results suggest that different mechanisms control coal porosity on different scales. Contrast-matching USANS and SANS were also used to determine the size distribution of the fraction of the pores in these coals that are inaccessible to deuterated methane, CD{sub 4}, at ambient temperature. In some coals most of the small ({approx} 10 nm) pores were found to be inaccessible to CD{sub 4} on the time scale of the measurement ({approx} 30 min - 16 h). This inaccessibility suggests that in these coals a considerable fraction of inherent methane may be trapped for extended periods of time, thus reducing the effectiveness of methane release from (or sorption by) these coals. Although the number of small pores was less in higher rank coals, the fraction of total

    The goals of this program include developing a system for the analysis of the chemical forms of organic sulfur in coal and for study of coal particle surfaces by multifrequency EPR spectroscopy, ENDOR, and ESE spectroscopy and Applying it to coals, to the effects of treatment upon their sulfur-containing organic components, and to related carbonaceous materials (chars and the like). The approach is to utilize the naturally-occurring unpaired electrons in the organic structures of coals as spies to provide molecular structure information, reading out the information with Electron Paramagnetic Resonance (EPR) spectroscopy. Several forms of EPR are employed: Multifrequency continuous-wave (CW) EPR, from 1 GHz to 240 GHz source frequency; electron-nuclear double resonance (ENDOR), in which NMR spectra at paramagnetic centers are obtained by EPR detection; and pulsed EPR, including ESE (Electron Spin Echo) spectroscopy.

    Due to environmental problems related to the combustion of high sulfur Illinois coal, there continues to be interest in the development in viable pre-combustion desulfurization processes. Recent studies by the authors have obtained very good sulfur removals but the reagents that are used are too expensive. Use of cheaper reagents leads to a loss of desired coal properties. This study investigated the application phase transfer catalysts to the selective oxidation of sulfur in coal using air and oxygen as oxidants. The phase transfer catalyst is expected to function as a selectivity moderator by permitting the use of milder reaction conditions that otherwise necessary. This would enhance the sulfur selectivity and help retain the heating value of the coal. The use of certain coal combustion wastes for desulfurization, and the application of cerium (IV) catalyzed air oxidation for selective sulfur oxidation are also being studied. If successful, this project could lead to the rapid development of a commercially viable desulfurization process. This would significantly improve the marketability of Illinois coal.

    A series of twenty-three aromatic compounds were ranked for their donor solvent efficacy for the dissolution of Western Kentucky No. 9/14 coal. The transfer of hydrogen from the solvent to the coal fragments, as measured by coal conversion, was examined at three levels of available hydrogen. The hydrogen donors are ranked according to their ability to convert coal to THF solubles. Aromatic analogs of the donors showed little ability to convert coal to THF solubles. Factors which influence hydrogen donation include the presence of heteroatoms or substituents both internal and external to the aromatic or hydroaromatic rings, the degree of hydrogenation, the aromaticity or nonaromaticity of the hydroaromatics, and the presence of five-membered rings. A relationship between heats of formation and hydrogen donor ability is shown for hydroaromatics within two ring or three ring homologous series. A model hydrogen acceptor, benzophenone, is also used to rank donors. No correlation exists in the ranking of hydrogen donors by the model acceptor used in this work and in other experimental studies and that obtained by conversion of Western Kentucky coal at typical liquefaction conditions. 24 references.

    The primary goal of this project is the engineering development of two advanced physical fine coal cleaning processes, column flotation and selective agglomeration, for premium fuel applications. The project scope includes laboratory research and bench-scale testing on six coals to optimize these processes, followed by design, and construction of a 2-t/hr process development unit (PDU). The PDU will then be operated to generate 200 tons of each of three project coals, by each process. During Quarter 11 (April--June, 1995), work continued on the Subtask 3.2 in-plant testing of the Microcel{trademark} flotation column at the Lady Dunn Preparation Plant with the installation and calibration of a refurbished 30-inch diameter column. The evaluation of toxic trace element data for column flotation samples continued, with preliminary analysis indicating that reasonably good mass balances were achieved for most elements, and that significant reductions in the concentration of many elements were observed from raw coal, to flotation feed, to flotation product samples. Significant progress was made on Subtask 6.5 selective agglomeration bench-scale testing. Data from this work indicates that project ash specifications can be met for all coals evaluated, and that the bulk of the bridging liquid (heptane) can be removed from the product for recycle to the process. The detailed design of the 2 t/hr selective agglomeration module progressed this quarter with the completion of several revisions of both the process flow, and the process piping and instrument diagrams. Procurement of coal for PDU operation began with the purchase of 800 tons of Taggart coal. Construction of the 2 t/hr PDU continued through this reporting quarter and is currently approximately 60% complete.

    The main goal of this project is to develop a bench-scale procedure to design and fabricate advanced brake and structural composite materials from Illinois coal combustion residues. During the first quarter of the project, the thrust of the work was directed towards setting up the experimental facilities and undertaking preliminary tests to gauge the ability of coal tar derived binder in fabricating the brake skeletons. In addition systematic scanning electron microscopy (SEM), differential scanning calorimetry (DSC), and differential thermal analysis (DTA) were conducted on PCC fly ash (Baldwin), fly ash (ADM), FBC fly ash, FBC spent bed bottom ash, bottom ash (ADM), and scrubber sludge residues to characterize their geometrical shape and thermal stability. The PCC fly ash particles being highly spherical in shape and thermally inert up to 1100{degrees}C will make an excellent raw material for our composites. This is born out by fabricating brake skeletons from PCC fly ash colloids. Unlike the PCC fly ash and FBC fly ash, the scrubber sludge particles are not suitable hosts for our brake lining materials because of a whisker-like particle structure. Six different compositions of various combustion residues were tested in the fabrication of brake skeletons, and our tar derived binder shows great promise in the fabrication of composite materials.

    This investigation seeks to utilize fly ash in fired-clay products such as building and patio bricks, ceramic blocks, field and sewer tile, and flower pots. This goal is accomplished by (1) one or more plant-scale, 5000-brick tests with fly ash mixed with brick clays at the 20% or higher level; (2) a laboratory-scale study to measure the firing reactions of a range of compositions of clay and fly ash mixtures; (3) a technical and economic study to evaluate the potential environmental and economic benefits of brick manufacture with fly ash. Bricks and feed materials will be tested for compliance with market specifications and for leachability of pollutants derived from fly ash. The laboratory study will combine ISGS databases, ICCI-supported characterization methods, and published information to improve predictions of the firing characteristics of Illinois fly ash and brick clay mixtures. Because identical methods are used to test clay firing and coal ash fusion, and because melting mechanisms are the same, improved coal ash fusion predictions are an expected result of this research. If successful, this project should convert an environmental problem (fly ash) into valuable products - bricks. During this quarter, the authors set up the manufacturing run at Colonial Brick Co., provided an expanded NEPA questionnaire for DOE, made preliminary arrangements for a larger brick manufacturing run at Marseilles Brick Co., revised laboratory procedures for selective dissolution analysis, and began characterization of brick clays that could be mixed with fly ash for fired-clay products.

    This represents the second quarterly progress report on Phase 2 of the Molten Salt Coal Gasification Process Development Unit (PDU) Program. Phase 1 of this program started in March 1976 and included the design, construction, and initial operation of the PDU. On June 25, 1980, Phase 2 of the program was initiated. It covers a 1-year operations program utilizing the existing PDU and is planned to include five runs with a targeted total operating time of 9 weeks. During this report period, Run 6, the initial run of the Phase 2 program was completed. The gasification system was operated for a total of 95 h at pressures up to 10 atm. Average product gas HHV values of 100 Btu/scf were recorded during 10-atm operation, while gasifying coal at a rate of 1100 lb/h. The run was terminated when the melt overflow system plugged after 60 continuous hours of overflow. Following this run, melt withdrawal system revisions were made, basically by changing the orifice materials from Monofrax to an 80 Cobalt-20 Chromium alloy. By the end of the report period, the PDU was being prepared for Run 7.

    The emphasis for the program at this time is to obtain results for specific process conditions of short residence time (< 2 sec.) and low H/sub 2//coal feed ratio (< 1.0) for select coals. The following conclusions can be drawn from this work: (1) The hydropyrolysis of New Mexico sub-bituminous coal produced considerable tar and less gaseous yields at short (< 1 second) residence times than at longer residence times. (2) The hydropyrolysis of Montana Rosebud sub-bituminous coal at 900/sup 0/C, 1000 psi, H/sub 2//coal ratios of approximately 0.8 to 0.6 and a residence time of 0.8 seconds produce yields of 23% gaseous hydrocarbons and 12% liquids. (3) Decreasing the H/sub 2//coal ratio to 0.25 at the same conditions results in a higher gaseous hydrocarbon yield and a reduced liquid yield. (4) Decreasing the residence time to 0.5 seconds, at the same conditions, decreases both the liquid and gaseous yields. (5) The liquid yield from the hydropyrolysis of the Montana Rosebud at 1000 psi maximizes as 12 to 14% at approximately 900/sup 0/C while the gaseous yield appears to continue to increase with temperature beyond the 27% measured at 940/sup 0/C. (6) Kentucky No. 9 coal produces approximately equal yields of liquids and gases (17%) at 900/sup 0/C and 1000 psi. (7) Carbon balances continue to improve but need further attention. (8) The calculated activation energy for the initial formation of hydrocarbons from both the lignite and sub-bituminous coals are almost identical (42,700 and 43,200 cal/gmole, respectively). (9) The correlation of the lignite data gave a slightly better overall correlation coefficient than the sub-bituminous data at the same 95% confidence limit (0.83 vs 0.78). (10) The free fall velocity of the coal particle at 900/sup 0/C and 1000 psi (0.8 ft/sec) becomes less significant at residence times less than 1 second.

    A review of the information concerning the structure of Illinois No. 6 coal obtained in this laboratory and elsewhere provides the basis for a proposed structure for this bituminous coal. All the available facts concerning reduction, reductive alkylation, hydrogen atom exchange, oxidation, functional group analysis and so forth have been used to define a structural segment consisting of about 1000 atoms with a molecular weight in excess of 6000. This work is discussed in Part A. The study of the reductive alkylation reaction of Illinois No. 6 coal in liquid ammonia has been directed toward the optimization of the reaction conditions for the achievement of maximum solubility. The latest results indicate that about 55% of the original Illinois No. 6 coal can be converted to products which are soluble in tetrahydrofuran using potassium in liquid ammonia as the reducing agent and n-butyl iodide in tetrahydrofuran as the reducing alkylating agent. These observations are treated in Part B. The effort on donor solvent coal chemistry was directed to the role played by pericyclic reactions in the liquefaction process. The reactivity of a number of donors has been examined including 1,2- and 1,4-dihydronaphthalene. Although the research is not yet complete, the preliminary results indicate that free radical processes occur preferentially. Thus, the pericyclic reactions appear to be unimportant at the threshold reaction temperatures of 350 to 425/sup 0/C. This work is described in Part C.

    The following conclusions can be drawn from this work: (1) when the caking bituminous coals are used with diluents, only 20% Pittsburgh No. 8 coal can be added to the diluent swhile 40% Illinois No. 6 could be added due to the higher free swelling index of the Pittsburgh No. 8; (2) When limestone is used as a diluent, considerably more sulfur is retained in the char than when using sand; (3) when the char from an experiment using limestone is recycled as the diluent for another experiment, the char continually retains additional sulfur through at least three recycles; (4) decomposition of the limestone and reduction is indicated by the high concentrations of CO observed at 900/sup 0/C; (5) increasing the coal feed rate by a factor of 4 from 2.4 to 10.7 lb/hr at low H/sub 2//Coal ratios (approx. = 0.6) results in no appreciable change in gaseous HC yields (approx. = 27%) or concentration (approx. = 45%) but higher BTX yields (1.1% vs. 5.4%); (6) although only one experiment was conducted, it appears that hydrogasification of untreated New Mexico sub-bituminous coal at 950/sup 0/C does not give an increase in yield over hydrogasification at 900/sup 0/C; (7) the hydrogasification of Wyodak lignite gives approximately the same gaseous HC yields as that obtained from North Dakota lignite but higher BTX yields particularly at 900/sup 0/C and 1000 psi (9% vs. 2%); (8) treating New Mexico sub-bituminous coal with NaCO/sub 3/ does not increase its hydrogasification qualities between 600/sup 0/C and 900/sup 0/C at 1000 psi but does decrease the BTX yield.

    Wyoming subbituminous coal was liquefied using three different two-stage process configurations in bench-scale tests. These process configurations differed in the type of fractionated deashing resid being recycled to the individual stages. The objective of these runs was to determine whether, by recycle of specific resid streams to the thermal stage, the second stage catalyst life could be improved without detrimentally affecting distillate yield or hydrogen consumption. The results indicate that the two-stage process configuration consisting of hydrotreating the Light Deashed Resid and direct recycle of heavy Deashed Resid to the thermal stage produced the best results. This process configuration resulted in a distillate yield of 54 wt % (MAF coal basis) and overall coal conversion in the 93 to 95% range, as measured by pyridine-soluble analytical test while operating in a total distillate mode. These results are very encouraging from the lower rank Wyoming subbituminous coal. Among the three two-stage process configurations tested, the particular process configuration of hydrotreating Light Deashed Resid resulted in the least amount of catalyst deactivation. As a part of this research effort, a test procedure for quick evaluation of various resids and catalysts in terms of coke precursors was also developed. This procedure utilizing as-produced oxide-form extrudates of catalyst is able to simulate closely in a batch reactor test the performance of a presulfided and extrudate form of catalyst in a continuous reactor. The CSD unit, being able to not only deash but also fractionate the resid, greatly increased the flexibility of options for coal liquefaction. New process concepts evolved incorporating reside fractionation and selective resid recycle in coal liquefaction. 17 figures, 28 tables.

    NMR relaxation and shift reagents are being deposited on the surface of coals. The dipolar coupling of the unpaired electron spin of the relaxation agent and the carbon atom should significantly shorten the carbon T, which should broaden it away. We propose to record the NMR spectrum of a coal before and after deposition and subtract the spectra. The difference spectra will arise from the functionalities within approximately one nanometer of the surface and reveal the surface composition of the coal. In order to determine the surface concentration of the dysprosium in the coal, we are using x-ray photoelectron spectroscopy (XPS) also known as electron spectroscopy for chemical analysis (ESCA). XPS is a surface technique that can be used for the elucidation of chemical structure. The binding energy for each electron in each element is unique. The measurement of the binding energy in XPS allows the identification of the element and its oxidation state. The relative atomic concentrations of each element can also be determined using XPS spectra.

    Bechtel, with Southwest Research Institute, Amoco Oil R&D, and the M.W. Kellog Co. as subcontractors, initiated a study on November 1, 1993 for the US Department of Energy`s (DOE`s) Pittsburgh Energy Technology Center (PETC) to determine the most cost effective and suitable combination of existing petroleum refinery processes needed to make specification transportation fuels or blending stocks, from direct and indirect coal liquefaction product liquids. The work has been divided into two parts, the Basic Program and Option 1. The objectives of the Basic Program are to characterize the coal liquids, develop an optimized refinery configuration for processing indirect and direct coal liquids, and develop a LP refinery model with the Process Industry Modeling System (PIMS) software. The objectives of Option 1 are to confirm the validity of the optimization work of the Basic Program, produce large quantities of liquid transportation fuel blending stocks, conduct engine emission tests, and determine the value and the processing costs of the coal liquids. The major efforts during the reporting period, October through December 1996, were in the areas of Option 1 blending and Option 1 FCC production run.

    The literature search on electrochemical studies of various carbons has been completed. Two conclusions were reached: (1) The surfaces of various carbons are covered by oxide films to different extents and the oxides resemble either the quinone-like structure in their oxidized form or the hydroquinone-like structure in the reduced form. (2) When carbonaceous materials are oxidized chemically, electrochemically, or thermally, the first stage involves formation of the oxide film and the later stages oxide gas (CO or CO/sub 2/) evolution. The catalytic reaction mechanism of coal oxidation was substantiated by adding Fe/sup 3 +/ or Ce/sup 4 +/ to a cell containing a coal slurry without passing any electrical current and by monitoring the amount of CO/sub 2/ evolved. Also, studies were performed on current efficiencies of CO/sub 2/ production reaction as a function of the particle size of coal samples. Finally, the catalytic rate constants of various redox catalysts for the coal oxidation reaction are reported. These results indicate that the thermodynamics of the reaction systems play a predominant role in determining the rate constants. Methods of studying the stability of semiconductor electrodes were established employing rotating ring-disk electrode techniques. The long-term stability of semiconductor electrodes would be needed to carry out the photoassisted coal gasification reaction. In the method we developed, the semiconductor was used as a disk electrode while the noble metal, e.g., Au or Pt, is used as a ring electrode. The species generated at the semiconductor electrode by light illumination is detected at the ring electrode by applying the proper electrode potential. If the ring detection current is lower than its expected value, the disk may undergo the photocorrosion reaction.

    Experimental work is continuing on four separate projects related to coal conversion processes. The direct digital control of exothermic multiphase reactions is being studied in an experimental adiabatic flow reactor. The existence of two stable steady states for the Fischer-Tropsch reaction network at the same temperature and feed condition has been verified and quantified. Various absorbents for SO/sub 2/ and NO/sub X/ are being studied. The absorption of NO/sub 2/ by methanol and N-cyclohexyl-2-pyrrolidone has been extensively examined. Preliminary data have been obtained with triethylene-tetraamine. Hindered amines will be studied next. Procedures for the preparation of liquid membranes have been tested and the incorporation of hindered amines in them will now be examined. Isotopic switching is being used to study the way in which promoters affect supported metal catalysts. With improved resolution from the mass spectrometer, early quantitative results give indications of three different surface species and of non-statistical ingrowth of /sup 13/C into the product molecules. A program for the study of the extraction of coal and oil shale using supercritical fluids is being carried out. The effect of the presence of piperidine on the amount of toluene solubles produced by supercritical extraction of coal with toluene/piperidine mixture has been determined. A new kinetic model for the extraction/liquefaction of coal by supercritical toluene and THF has been developed and proven satisfactory. Bruceton coal and Hi Na lignite have been extracted with supercritical water. 3 references, 7 figures, 6 tables.

    The primary goal of this project is the engineering development of two advanced physical fine coal cleaning processes, column flotation and selective agglomeration, for premium fuel applications. The project scope includes laboratory research and bench-scale testing on six coals to optimize these processes, followed by design, and construction and operation of a 2-t/hr process development unit. The project began in October, 1992, and is scheduled for completion by June, 1997. During Quarter 12 (July--September 1995), work continued on the Subtask 3.2 in-plant testing of the Microcel{trademark} flotation column at Lady Dunn. Under Subtask 4.4, additional toxic trace element analysis of column flotation samples finalized the data set. Data analysis indicates that reasonably good mass balances were achieved for most elements. The final Subtask 6.3 Selective Agglomeration Process Optimization topical report was issued this quarter. Preliminary Subtask 6.4 work investigating coal-water-fuel slurry formulation indicated that selective agglomeration products formulate slurries with lower viscosities than advanced flotation products. Work continued on Subtask 6.5 agglomeration bench-scale testing. Results indicate that a 2 lb ash/MBtu product could be produced at a 100-mesh topsize with the Elkhorn No. 3 coal. The detailed design of the 2 t/hr selective agglomeration module neared completion this quarter with the completion of additional revisions of both the process flow, and the process piping and instrument diagrams. Construction of the 2 t/hr PDU and advanced flotation module was completed this quarter and startup and shakedown testing began.

    This report summarizes the progress made during the first quarter of the research project entitled ``A Novel Microorganism for Selective Separation of Coal from Ash and Pyrite,`` DOE Grant No. DE-FG22-93PC93215. The objective of this project is to study the effectiveness of a novel hydrophobic microorganism, Mycobacterium phlei (M. phlei), for the selective flocculation of coal from pyrite and ash-forming minerals. During the reporting period, three different coal samples: Illinois No. 6 coal, Kentucky No. 9 coal and Pittsburgh No. 8 coal, were collected to be used in the investigation. The microorganism, M. phlei, was obtained as freeze-dried cultures and the growth characteristics of the bacteria were studied. Scanning electron microphotographs revealed that M. phlei cells are coccal in shape and are approximately 1 {mu}m in diameter. Electrokinetic measurements showed that the Illinois No. 6 and Pittsburgh No. 8 coal samples had an isoelectric point (IEP) around pH 6 whereas M. phlei had an IEP around pH 1.5. Electrokinetic measurements of the ruptured microorganisms exhibited an increase in IEP. The increase in IEP of the ruputured cells was due to the release of fatty acids and polar groups from the cell membrane.

    Froth flotation technique is an effective and efficient process for recovering of ultra-fine (minus 74{mu}m) clean coal. Economical dewatering of an ultrafine clean coal product to a 20% level moisture will be an important step in successful implementation of the advanced cleaning processes. The main objective of the proposed program is to evaluate a novel surface modification technique, which utilizes the synergistic effect of metal ions-surfactant combination, for dewatering of ultra-fine clean coal on a proof-of-concept scale of 1 to 2 tph. The novel surface modification technique developed at the the University of Kentucky Center for Applied Energy Research will be evaluated using vacuum, centrifuge, and hyperbaric filtration equipment. Dewatering tests will be conducted using the fine clean coal froth produced by the column flotation units at the Powell Mountain Coal Company, Mayflower Preparation Plant in St. Charles, Virginia. The POC-scale studies will be conducted on two different types of clean coal, namely, high sulfur and low sulfur clean coal. Accomplishments for the past quarter are described.

    The goals of the program are to develop a coal-fired high performance power generation system (HIPPS) by the year 2000 that is capable of > 47% thermal efficiency; NO{sub x} SO {sub x} and Particulates < 25% NSPS; Cost of electricity 10% lower; coal > 65% of heat input and all solid wastes benign. In order to achieve these goals our team has outlined a research plan based on an optimized analysis of a 250 MW{sub e} combined cycle system applicable to both frame type and aeroderivative gas turbines. Under the constraints of the cycle analysis we have designed a high temperature advanced furnace (HITAF) which integrates several combustor and air heater designs with appropriate ash management procedures. Most of this report discusses the details of work on these components, and the R&D Plan for future work. The discussion of the combustor designs illustrates how detailed modeling can be an effective tool to estimate NO{sub x} production, minimum burnout lengths, combustion temperatures and even particulate impact on the combustor walls. When our model is applied to the long flame concept it indicates that fuel bound nitrogen will limit the range of coals that can use this approach. For high nitrogen coals a rapid mixing, rich-lean, deep staging combustor will be necessary. The air heater design has evolved into two segments: a convective heat exchanger downstream of the combustion process; a radiant panel heat exchanger, located in the combustor walls; The relative amount of heat transferred either radiatively or convectively will depend on the combustor type and the ash properties.

    This investigation seeks to utilize fly ash in fired-clay products such as building and patio bricks, ceramic blocks, field and sewer tile, and flower pots. This goal is accomplished by (1) one or more plant-scale, 5000-brick tests with fly ash mixed with brick clays at the 20% or higher level; (2) a laboratory-scale study to measure the firing reactions of a range of compositions of clay and fly ash mixtures; (3) a preliminary study to evaluate the potential environmental and economic benefits of brick manufacture with fly ash. Bricks and feed materials will be tested for compliance with market specifications and for leachability of pollutants derived from fly ash. The laboratory study will combine ISGS databases, ICCI-supported characterization methods, and published information to improve predictions of the firing characteristics of Illinois fly ash and brick clay mixtures. Because identical methods are used to test clay firing and coal ash fusion, and because melting mechanisms are the same, improved coal ash fusion predictions are an additional expected result of this research. If successful, this project should convert a disposal problem (fly ash) into valuable products-bricks. During this quarter we set up the manufacturing run at Colonial Brick Co., finalized arrangements for a larger brick manufacturing run at Marseilles Brick Co. in YR2, revised our laboratory procedures for selective dissolution analysis, obtained information to select three standard fly ashes, and continued our characterization of brick clays that could be mixed with fly ash for fired-clay products. Due to delays in other areas, we began construction of the optimization program for year 2. We discovered recently that fly ash dust will be an unanticipated problem at the brick plant.

    A model-based flotation control scheme is being implemented to achieve optimal performance in the handling and treatment of fine coal. The control scheme monitors flotation performance through on-line analysis of ash content. Then, based on the economic and metallurgical performance of the circuit, variables such as reagent dosage, pulp density and pulp level are adjusted using model-based control algorithms to compensate for feed variations and other process disturbances. Recent developments in sensor technology are being applied for on-line determination of slurry ash content. During the fourth quarter of this project, a final attempt was made to calibrate a video-based ash analyzer for use in this application. It was concluded that the low ash content and the coarse particle size of the flotation tailings slurry at the Maple Meadow plant site made the video-based system unsuitable for this application. Plans are now underway to lease a nuclear-based analyzer as the primary sensor for this project.

    The United States Department of Energy, Morgantown Energy Research Center (DOE/METC), is sponsoring the development of direct coal-fired turbine power plants as part of their Heat Engines program. A major technical challenge remaining for the development of the direct coal-fired turbine is high-temperature combustion gas cleaning to meet environmental standards for sulfur oxides and particulate emissions, as well as to provide acceptable turbine life. The Westinghouse Electric Corporation, Science & Technology Center, is evaluating two Integrated Low Emissions Cleanup (ILEC) concepts that have been configured to meet this technical challenge: a baseline ceramic barrier filter ILEC concept, and a fluidized bed ILEC concept. These ILEC concepts simultaneously control sulfur, particulate, and alkali contaminants in the high-pressure combustion gases at turbine inlet temperatures up to 2300{degrees}F. This document reports the status of a program in the seventeenth quarter to develop this ILEC technology for direct coal-fired turbine power plants.

    Manganese-based sorbents have been investigated for the removal of hydrogen sulfide (the primary sulfur bearing compound) from hot coal gases prior to its use in combined cycle turbines. Four formulations of Mn-based sorbents were tested in an ambient-pressure fixed-bed reactor to determine steady state H{sub 2}S concentrations, breakthrough times and effectiveness of the sorbent when subjected to cyclic sulfidation and regeneration testing. In a previous report, the sulfidation results were presented. Manganese-based sorbents with molar ratios > 1:1 Mn:Substrate were effective in reducing the H{sub 2}S concentration in simulated coal gases to less than 100 ppmv over five cycles. Actual breakthrough time for formulation C6-2-1100 was as high as 73% of breakthrough time based on wt% Mn in sorbent. In this report, the regeneration results will be presented. Regeneration tests determined that loaded pellets can be fully regenerated in air/steam mixture at 750{degrees}C with minimal sulfate formation. 16 refs., 9 figs., 5 tabs.

    The field-ionization mass spectral hydrocarbon data from F-45 (Wyodak coal-derived SRC) and F-51 (Kentucky 9/14 coal-derived SRC) were recalculated so the various hydrocarbon fractions could be compared directly on a weight percent basis. A computer program was developed which allows the field-ionization mass spectral hydrocarbon data to be compared in a three dimensional fashion. This approach provides for a rapid general comparson of all the field-ionization hydrocarbon data. The solubility of preasphaltenes was tested in several solvents. The preasphaltenes-2 were found to be largely soluble in pyridine:chloroform 9:1(v/v) or 7:3(v/v) and pyridine:chloroform:tetrahydrofuran 7:1:2(v/v/v). Experiments were carried out in which Chromasorb T was tested as a replacement for Fluoropak in the Fluoropak-basic alumina procedure. The results indicated Chromasorb T would be an adequate substitute for Fluoropak, but additional experiments will be run to confirm this. The chromatographic characteristics of numerous hydroxyl aromatics, nitrogen heterocycles, and aromatic amines were obtained on several normal-phase and reversed-phase high-performance liquid chromatographic systems. 30 references, 30 figures, 10 tables.

    The basic objectives of this new program are, firstly, to understand the systematic relationships between the properties of coals and macerals, and, secondly, to determine the lateral and vertical variability in the properties of a single seam imposed by varying environmental conditions at the time of coal formation. Thirty-four coal samples were collected during the quarter from Pennsylvania and Illinois. To date, 54 vitrinite concentrates have been hand picked and will be studied by a range of physical and chemical techniques. One hundred and forty coal samples and 53 printouts of coal data were provided on request to the coal research community. The Lower Kittanning seam has been selected for the study of the variability in chemical, petrographic, mineralogic, fluid, and conversion properties of a single seam. A description of the structural and stratigraphic settings of the important coal seam as they relate to this investigation is given. Bivariate plots of data from the Lower Kittanning seam are presented. The fluid temperature range as measured with the Gieseler plastometer reaches a maximum at a reflectance of 1.10 to 1.15% and carbon content of 87 to 88% dmmf. Liquefaction conversion in a tubing-bomb reactor with tetralin shows a linear decrease with rank (reflectance). The problems associated with the application Fourier Transform Infrared Spectroscopy to the characterization of coal structure are critically discussed. The micropore surface areas and micropore volumes of three selected coals and a vitrinite concentrate, as measured from uptake of CO/sub 2/ at 25/sup 0/C, increased with decreasing particle size. Work on measurements of apparent densities and uptake of methanol and water is in progress.

The project scope includes laboratory research and bench-scale testing on six coals to optimize these processes, followed by the design, construction, and operation of a 2-t/hr process development unit. During Quarter 13 (October--December 1995), testing of the GranuFlow dewatering process indicated a 3--4% reduction in cake moisture for screen-bowl and solid-bowl centrifuge products. The Orimulsion additions were also found to reduce the potential dustiness of the fine coal, as well as improve solids recovery in the screen-bowl centrifuge. Based on these results, Lady Dunn management now plans to use a screen bowl centrifuge to dewater their Microcel{trademark} column froth product. Subtask 3.3 testing, investigating a novel Hydrophobic Dewatering process (HD), continued this quarter. Continuing Subtask 6.4 work, investigating coal-water-slurry formulation, indicated that selective agglomeration products can be formulated into slurries with lower viscosities than advanced flotation products. Subtask 6.5 agglomeration bench-scale testing results indicate that a very fine grind is required to meet the 2 lb ash/MBtu product specification for the Winifrede coal, while the Hiawatha coal requires a grind in the 100- to 150-mesh topsize range. Detailed design work remaining involves the preparation and issuing of the final task report. Utilizing this detailed design, a construction bid package was prepared and submitted to three Colorado based contractors for quotes as part of Task 9.

    The objective of this project is to produce electrode binder pitch with sulfur content below 0.6 wt% from high-sulfur Illinois coal mild gasification liquids. Previously, flash thermocracking (FTC) was used to successfully upgrade the properties of mild gasification pitch, yielding a suitable blending stock for use as a binder in the production of carbon electrodes for the aluminum industry. However, in pitches from high-sulfur (4%) Illinois coal, the pitch sulfur content (2%) was still higher than preferred. In this project two approaches to sulfur reduction are being explored in conjunction with FTC: (1) the use of a moderate-sulfur (1.2%) Illinois coal as mild gasification feedstock, and (2) direct biodesulfurization of the liquids from high-sulfur coal prior to FTC. In Case 1, the liquids are being produced by mild gasification of IBC-109 coal in a bench-scale fluidized-bed reactor, followed by distillation to isolate the crude pitch. In Case 2, biodesulfurization with Rhodococcus Rhodochrous IGTS8 biocatalyst is being performed on crude pitch obtained from Illinois No. 6 coal tests conducted in the IGT MILDGAS PRU in 1990. Following preparation of the crude pitches, pitch upgrading experiments are being conducted in a continuous FTC reactor constructed in previous ICCI-sponsored studies. This quarter, mild gasification of IBC-109 coal was completed, producing 450 g of coal liquids, which were then distilled to recover 329 g of Case 1 crude pitch. Next month, the pitch will be subjected to FTC treatment and evaluated. Biodesulfurization experiments were performed on Case 2 pitch dispersed in l-undecanol, resulting in sulfur reductions of 15.1 to 21.4%. This was marginally lower than the 24.8% desulfurization obtained in l-dodecanol, but separation of pitch from the dispersant was facilitated by the greater volatility of l-undecanol.

    The project objective is to design, construct, install provide operator training and start-up a circulating fluidized bed combustion system at the Lebanon Pennsylvania Veteran`s Affairs Medical Center. This unit will co-fire coal and hospital waste providing lower cost steam for heating and possibly cooling (absorption chiller) and operation of a steam turbine-generator for limited power generation. This would permit full capacity operation of the FBC year round in spite of the VA laundry that was shut down as well as efficient destruction of both general and infectious hospital waste and steam generation. The State permitting process required for construction will be completed in early November to allow installation and construction to be completed. Operating permits will be obtained after construction has been completed. A request for proposal for stack sampling and biospore tests was released to four (4) vendors in mid-October. The proposals shall be reviewed during November and the stack sampler will be selected. Funding was approved as of August 1, 1995. Construction and installation resumed on August 21, 1995 at the LVAMC. Construction and installation continues and will be completed by late December 1995.

    1997-05-02

    Research Triangle Institute (RTI), Eastman Chemical Company, and Bechtel collectively are developing a novel process for the synthesis of methyl methacrylate (MMA) from coal-derived syngas, under a contract from the US Department of Energy, Federal Energy Technology Center. This three-step process consists of synthesis of a propionate, its condensation with formaldehyde, and esterification of resulting methacrylic acid (MAA) with methanol to produce MMA. Eastman has focused on the propionate synthesis step. the resultant Mo catalysts work efficiently at much less severe conditions (170{degrees}C and 30 atm) than the conventional Ni catalysts (270{degrees}C and 180 atm). Bechtel has performed an extensive cost analysis which shows that Eastman`s propionate synthesis step is competitive with other technologies to produce the anhydride. In the second step, RTI and Eastman have developed active and stable V-Si-P ternary metal oxide catalysts Nb/SiO{sub 2} and Ta/SiO{sub 2} catalysts for the condensation of propionic anhydride and acid with formaldehyde. RTI has demonstrated a novel correlation among the catalyst acid-base properties, condensation reaction yield, and long-term catalyst activity. Current research focuses on enhancing the condensation reaction yields by better understanding of the acid-base property correlation, in situ condensation in a high-temperature, high- pressure (HTHP) slurry reactor, and alternate formaldehyde feedstocks. Based on Eastman and RTI laboratory data, a cost estimate is also being developed for the integrated process.

    This document a quarterly report prepared in accordance with the project reporting requirements covering the period from July 1, 1992 to September 30, 1992. This report provides a summary of the technical work undertaken during this period, highlighting the major results. A brief description of the work done prior to this quarter is provided in this report under the task headings. The overall project scope of the engineering development project is to conceptually develop a commercial flowsheet to maximize pyritic sulfur reduction at practical energy recovery values. This is being accomplished by utilizing the basic research data on the surface properties of coal, mineral matter and pyrite obtained from the Coal Surface Control for Advanced Fine Coal Flotation Project, to develop this conceptual flowsheet. The conceptual flowsheet must be examined to identify critical areas that need additional design data. This data will then be developed using batch and semi-continuous bench scale testing. In addition to actual bench scale testing, other unit operations from other industries processing fine material will be reviewed for potential application and incorporated into the design if appropriate. The conceptual flowsheet will be revised based on the results of the bench scale testing and areas will be identified that need further larger scale design data verification, to prove out the design.

    A confined core of a Pittsburgh #8 coal obtained from a mine near Waynesburg, Pennsylvania, has been investigated using computerized tomography. The 3-D density distribution of the coal was calculated for the stressed and confined core with, and without CO2 sorption. We used a dual energy technique to quantify volumetric variations in bulk density and effective atomic number. CO2 sorption of coal was then investigated at predetermined injection pressures. The density changes in the coal matrix were calculated and correlated with the CO2 adsorbed for a multitude of regions of interest (ROI) chosen in slices perpendicular to the bedding plane. The results show that even in small core samples, coal heterogeneity is high. Large variation of density was observed in small regions of interest compared to the average density of slices. Also, the coal density distribution was changed significantly due to the CO2 uptake. This technique seems very useful in calculating density distribution for stressed and confined coal samples and the change in volumetric density distribution due to CO2 adsorption. Furthermore the kinetics of heterogeneous adsorption and swelling in coal can be determined.

    Work on Phase I of the Contract program is essentially complete and was reported in the Phase I Technical Report which has been reviewed and accepted by the Contract Technical Project Officer. Phase I work included a survey of relevant technical literature and development, demonstration and documentation of a computer model, MINE1D, for flow of methane and water in coal strata for geometries corresponding to an advancing mine face and to a mine pillar. The Phase I models are one-dimensional in the space variable but describe time-dependent (nonsteady) phenomena and include gas sorption phenomena. Some revisions have been made to input/output sections of MINE1D and the documentation has been expanded. These modifications will be reported in the next Quarterly Technical Report. Preliminary test scenarios have been formulated and reviewed with the Contract Technical Project Officer for measurement of emissions during room-and-pillar and longwall mining operations. These preliminary scenarios are described in this report. A mathematical model has been developed to describe the increased stresses on the coal seam near mine openings. The model is based on an approximate elastic/plastic treatment of the coal seam and an elastic treatment of surrounding strata. In this model, elastic compaction of the coal seam decreases porosity and permeability, whereas plastic deformation increases the porosity of the natural fracture network and thereby increases the permeability. The model takes into account the effect of changes in pore fluid pressure (in the natural fracture network of the coal seam) on the deformation of the coal seam. This model is described in this report, and will be programmed for inclusion in revised versions of MINE1D and for use in the two-dimensional computer models now under development. 8 figures.

    In the fourth quarter of calendar year 1995 the installation and checkout of the 20 MMBtu/hr combustor and auxiliary equipment in Philadelphia was completed. The task 5, Site Demonstration Testing, combustor-boiler tests on gas, oil, and coal were initiated. The task 5 effort involves testing the combustor over extended periods under conditions that fully simulate commercial operation and that meet the combustion and environmental specifications for this project. To meet this project objective within the current work scope requires up to 500 hours of testing. The focus of this testing will be on the component and environmental performance of combustor, boiler, coal preparation and feeding, and the stack gas equipment. The facility can be converted to a 500 kW power plant by the addition of a steam turbine, condenser, and cooling tower. However, this added effort is beyond the current work scope and its implementation will depend on recovering the added costs by placing the steam production from the boiler to beneficial use. During the present quarterly reporting period, all the components needed to implement the initial 100 hours of testing under task 5 were installed at the test site, and checkout of this equipment was performed. Since the present installation contained substantial improvements and simplifications to all sub-systems that had been used in the Williamsport facility, each component and sub-system had to be tested individually.

    The temperature distribution in a liquefaction reactor in the integrated TSL process is studied. The effects of gas and slurry superficial velocities, process solvent characteristics, reactor length, and catalyst sulfiding agent on the exotherm and temperature difference in the reactor are studied. A substantial temperature difference is observed with subbituminous coal as compared with bituminous coal, at comparable reactor conditions. Some of the factors that are believed to have contributed to the large exotherm and temperature difference in the reactor are slow kinetics and high reaction heat for subbituminous coal conversion and pyrrhotite catalysis.

    Illinois Basin coal often contains a significant portion of finely dispersed pyrite. Most of the free pyrite particles exist in the fine size fractions, which are generally treated using froth flotation. An inherent problem of the froth flotation process is the inefficient treatment of middling particles containing a small amount of coal on their surface. On the other hand, gravity-based processes can effectively remove middling particles containing only a small amount of coal. Falcon Concentrators Inc. and Knelson Gold Concentrators Inc. have developed full-scale, enhanced gravity separators for the treatment of heavy minerals. This project will evaluate the potential of using these concentrators to de-ash and de-sulfurize Illinois coal fines, thus, producing coal products that meet the requirements for Phase I of the Clean Air Act. Since both continuous separators are commercially available, the results obtained in this investigation should be applicable to industrial operations.

    Coals of different ranks will be pyrolyzed in a microscope hot-stage reactor using inert and reacting atmospheres. The macropore structure of the produced chars will be characterized using video microscopy and digital image processing techniques to obtain pore size distributions. Comparative studies will quantify the effect of pyrolysis conditions (heating rates, final heat treatment temperatures, particle size and inert or reacting atmosphere) on the pore structure of the devolatilized chars. The devolatilized chars will be gasified in the regime of strong intraparticle diffusional limitations using O{sub 2}/N{sub 2} and O{sub 2}/H{sub 2}O/N{sub 2}2 mixtures. Constant temperature and programmed-temperature experiments in a TGA will be used for these studies. Additional gasification experiments performed in the hot-stage reactor will be videotaped and selected images will be analyzed to obtain quantitative data on particle shrinkage and fragmentation. Discrete mathematical models will be developed and validated using the experimental gasification data.

    The primary goal of this project is the engineering development of two advanced physical fine coal cleaning processes, column flotation and selective agglomeration, for premium fuel applications. The project scope includes laboratory research and bench-scale testing on six coals to optimize these processes, followed by design, and construction of a 2-t/hr process development unit (PDU). The PDU will then be operated to generate 200 ton lots of each of three project coals, by each process. The project began in October, 1992 and is scheduled for completion by March, 1997. During Quarter 9 (October--December, 1995), parametric and optimization testing was completed for the Taggart, Sunnyside, and Indiana VII coal using a 12-inch Microcel{trademark} flotation column. The detailed design of the 2-t/hr PDU grinding, flotation, and dewatering circuits neared completion with the specification of the major pieces of capital equipment to be purchased for these areas. Selective agglomeration test work investigated the properties of various industrial grades of heptane for use during bench- and PDU-scale testing. It was decided to use a hydrotreated grade of commercial heptane due to its low cost and low concentration of aromatic compounds. The final Subtask 6.4 CWF Formulation Studies Test Plan was issued. A draft version of the Subtask 6.5 Preliminary Design and Test Plan Report was also issued, discussing the progress made in the design of the bench-scale selective agglomeration unit. PDU construction work moved forward through the issuing of 26 request for quotations and 21 award packages for capital equipment.

    The overall objective of this program is the development of predictive capability for the design, scale up, simulation, control and feedstock evaluation in advanced coal conversion devices. This technology is important to reduce the technical and economic risks inherent in utilizing coal, a feedstock whose variable and often unexpected behavior presents a significant challenge. This program will merge significant advances made at Advanced Fuel Research, Inc. (AFR) in measuring and quantitatively describing the mechanisms in coal conversion behavior, with technology being developed at Brigham Young University (BYU) in comprehensive computer codes for mechanistic modeling of entrained-bed gasification. Additional capabilities in predicting pollutant formation will be implemented and the technology will be expanded to fixed-bed reactors. The program includes: (i) validation of the submodels by comparison with laboratory data obtained in this program, (ii) extensive validation of the modified comprehensive code by comparison of predicted results with data from bench-scale and process scale investigations of gasification, mild gasification and combustion of coal or coal-derived products in heat engines, and (iii) development of well documented user friendly software applicable to a ``workstation`` environment. Success in this program will be a major step in improving the predictive capabilities for coal conversion processes including: Demonstrated accuracy and reliability and a generalized ``first principles`` treatment of coals based on readily obtained composition data.

    The objective of this work is to explore the technoeconomic feasibility of a series of unit operations involving: (1) wet grinding of coal in water; (2) removal of chlorine and sodium, release of undesirable mineral matter, and chemical incorporation, if needed, of a disposable liquefaction catalyst in coal via hot water teatment; (3) oil agglomeration to dewater and deash coal while retaining most of the pyrite; and (4) solvent drying of coal agglomerates to eliminate oxidation of coal, improve coal liquefaction reactivity, save energy and prepare the coal/solvent slurry for liquefaction. An apparatus capable of running five microautoclaves simultaneously has been designed and constructed. The autoclaves are shaken along the long axis to insure good mixing and pressure and temperature can be monitored in each autocalve during the run. Reproducibility experiments indicate that the standard deviation on the conversion to THF solubles is about 2.5 percent. The standard deviations in conversions to preasphaltenes and asphaltenes are much higher. A five-autoclave experiment has confirmed earlier results which indicate that wet grinding and hot-water treatment have little effect on conversion to THF solubles but that oil agglomeration followed by drying in a vacuum oven causes a large increase and oil agglomeration followed by solvent drying causes a significant but smaller increase in conversion. 5 references, 13 figures.

    A potentially new use for Illinois coal is its use as a fuel injected into a blast furnace to produce molten iron as the first step in steel production. Because of its increasing cost and decreasing availability, metallurgical coke is now being replaced by coal injected at the tuyere area of the furnace where the blast air enters. The purpose of this study is to evaluate the combustion of coal during the blast furnace injection process and to delineate the optimum properties of the feed coal. The basic program is designed to determine the reactivity of both coal and its derived char under blast furnace conditions and to compare the results to similar properties of blast furnace coke. The results of the first two experiments in which coal char pyrolyzed in nitrogen at 1000{degrees}C in an EPR were reacted isothermally in air at 1000{degrees}C and 1200{degrees}C. The reactivity values of the same char in these two experiments were different by an order of magnitude. The char reactivity at 1000{degrees}C was 9.7 {times} 10{sup {minus}4} grams per minute while the reactivity. of the char at 1200{degrees}C was 1.6 {times} 10{sup {minus}3} grams per minute. These results suggest that the temperature of the blast air in the tuyere may be critical in achieving complete carbon burnout.

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

    The objective of this project is to demonstrate and evaluate commercially available Selective Catalytic Reduction (SCR) catalysts from U.S., Japanese, and European catalyst suppliers on a high-sulfur U.S. coal-fired boiler. SCR is a post-combustion nitrogen oxide (NOx) control technology that involves injecting ammonia into the flue gas generated from coal combustion in an electric utility boiler. The flue gas containing ammonia is then passed through a reactor that contains a specialized catalyst. In the presence of the catalyst, the ammonia reacts with NOx to convert it to nitrogen and water vapor. Although SCR is widely practiced in Japan and Europe on gas-, oil-, and low-sulfur coal-fired boilers, there are several technical uncertainties associated with applying SCR to U.S. coals. These uncertainties include: (1) potential catalyst deactivation due to poisoning by trace metal species present in U.S. coals that are not present in other fuels; (2) performance of the technology and effects on the balance-of-plant equipment in the presence of high amounts of SO{sub 2} and SO{sub 3}; and (3) performance of a wide variety of SCR catalyst compositions, geometries and methods of manufacture under typical high-sulfur coal-fired utility operating conditions. These uncertainties are being explored by constructing and operating a series of small-scale SCR reactors and simultaneously exposing different SCR catalysts to flue gas derived from the combustion of high sulfur U.S. coal. The demonstration is being performed at Gulf Power Company`s Plant Crist Unit No. 5 (75 MW capacity) near Pensacola, Florida. The project is funded by the U.S. Department of Energy (DOE), Southern Company Services, Inc. (SCS on behalf of the entire Southern electric system), the Electric Power Research Institute (EPRI), and Ontario Hydro. SCS is the participant responsible for managing all aspects of this project.

    Significant advances have been made at Brigham Young University (BYU) in comprehensive two-dimensional computer codes for mechanistic modeling of entrained-bed gasification and pulverized coal combustion. During the same time period, significant advances have been made at Advanced Fuel Research, Inc. (AFR) in the mechanisms and kinetics of coal pyrolysis and secondary reactions of pyrolysis products. This program presents a unique opportunity to merge the technology developed by each organization to provide detailed predictive capability for advanced coal characterization techniques in conjunction with comprehensive computer models to provide accurate process simulations. The program will streamline submodels existing or under development for coal pyrolysis chemistry, volatile secondary reactions, tar formation, soot formation, char reactivity, and SO{sub x}-NO{sub x} pollutant formation. Submodels for coal viscosity, agglomeration, tar/char secondary reactions, sulfur capture, and ash physics and chemistry will be developed or adapted. The submodels will first be incorporated into the BYU entrained-bed gasification code and subsequently, into a fixed-bed gasification code (to be selected and adapted). These codes will be validated by comparison with small scale laboratory and PDU-scale experiments. Progress is described.

    In our laboratories we have previously developed a mild coal conversion process. This involves the use of a superacid system consisting of HF and BF{sub 3} in presence of hydrogen and/or a hydrogen donor solvent. In order to understand the chemistry involved in the process of depolymerization of coal by the HF:BF{sub 3}:H{sub 2} system we are carrying out a systematic study of a number of coal model compounds. The model compounds selected for present study have two benzene rings connected with various bridging units such as alkylidene, ether, sulfide etc. From studies so far carried out it appears that high pyridine extractibilities achieved by treating coal at temperature below 100 degrees C results from the cleavage of bridges such as present in bibenzyl, diphenyl methane, dibenzyl ether, dibenzyl sulfide etc. On the other hand the increased cyclohexane extractibility and distillability observed at relatively higher temperatures and hydrogen pressures reflects the hydrogenation and cleavage of the aromatic backbone in coal structure similar to what is seen in the conversion of model compounds such as biphenyl, diphenyl ether, diphenyl sulfide, anthracene, etc.

    The basic objectives of this program are, first, to understand the systematic relationships between the properties of coals, and, second, to determine the nature of the lateral and vertical variability in the properties of a single seam. Multivariate statistical analyses applied to the Coal Data Base confirm a number of known trends for coal properties. In addition, nitrogen and some components of the ash analysis bear interesting relationships to rank. The macroscopic petrography of column samples of the Lower Kittanning seam reveals a significant difference between the sample from a marine-influenced environment and those from toward the margins of the basin where conditions were non-marine. The various methods of determining the amount and mineralogy of the inorganic fraction of coals are reviewed. General trends in seam thickness, ash, sulfur, volatile matter yield, and vitrinite reflectance of the Lower Kittanning seam of western Pennsylvania are presented. Controls of sedimentation are discussed in relation to the areal variability which has been observed. Differential subsidence and paleotopography appear to have played a major role during the deposition of the coal. The same controls may have maintained some influence upon the coalification process after deposition, especially along the eastern margin of the Lower Kittanning basin.

    The overall objective of this program is the development of predictive capability for the design, scale up, simulation, control and feedstock evaluation in advanced coal conversion devices. This technology is important to reduce the technical and economic risks inherent in utilizing coal, a feedstock whose variable and often unexpected behavior presents a significant challenge. This program will merge significant advances made at Advanced Fuel Research, Inc. (AFR) in measuring and quantitatively describing the mechanisms in coal conversion behavior, with technology being developed at Brigham Young University (BYU) in comprehensive computer codes for mechanistic modeling of entrained-bed gasification. Additional capabilities in predicting pollutant formation will be implemented and the technology will be expanded to fixed-bed reactors. The foundation to describe coal-specific conversion behavior is AFR`s Functional Group (FG) and Devolatilization, Vaporization and Crosslinking (DVC) models, developed under previous and on-going METC sponsored programs. These models have demonstrated the capability to describe the time dependent evolution of individual gas species, and the amount and characteristics of tar and char. The combined FG-DVC model will be integrated with BYU`s comprehensive two-dimensional reactor model, PCGC-2, which is currently the most widely used reactor simulation for combustion or gasification. The program includes: (i) validation of the submodels by comparison with laboratory data obtained in this program, (ii) extensive validation of the modified comprehensive code by comparison of predicted results with data from bench-scale and process scale investigations of gasification, mild gasification and combustion of coal or coal-derived products in heat engines, and (iii) development of well documented user friendly software applicable to a ``workstation`` environment.

    This report describes work accomplished under two task: Task A, Mechanism of Cleavage of Key Bond types Present in Coals, and Task B, Catalysis of Conversion in CO-H/sub 2/O Systems. Under Task A, we have made additional measurements of catalytic carbon-carbon and carbon-oxygen bond cleavage in coal-related diphenylmethane and diphenyl ether structures. The results provide further support for, but do not definitely confirm, the tentative conclusion that the highly effective iron oxide catalysts involves oxidation to radical cation species. The homogeneous scission of carbon-oxygen bonds in diphenyl ether structure has also been studied. In the Task B studies of CO-H/sub 2/O systems, we typically obtain 50% benzene-soluble product material from 20 min. reaction of beneficiated Illinois No. 6 coal. This conversion level is obtained with aqueous solutions either at a starting pH above 12.6 or in neutral solutions with water-soluble catalysts present. We have studied a number of catalysts, including the potassium or sodium salts of molybdate, chromate, manganate, and tungstate; all are effective in the 3000 to 6000 ppM range. A striking result is that sodium nitrate at 6000 ppM is as effective as the metal salts. We found that the nitrate was converted to ammonium ion; also, formate was detected in the product aqueous phase. Finally, we find that catalytic quantities of sodium formate in CO/H/sub 2/O at pH 7 are effective in the conversion. However, in a control run in N/sub 2//H/sub 2/O, with a quantity of sodium formate equivalent to twice the molar quantity of hydrogen transferred to the coal in a successful run, the coal was converted to a product totally insoluble in benzene and with a lower hydrogen content than the starting coal.

    The goal of this research is to produce a pellet fuel from low-sulfur Illinois coal fines which could burn with emissions of less than 1.8 lbs SO{sub 2}/10{sup 6} Btu in stoker-fired boilers. The significance of 1.8 lbs SO{sub 2}/10{sup 6} Btu is that in the Chicago (9 counties) and St. Louis (2 counties) metropolitan areas, industrial users of coal currently must comply with this level of emissions. Stokers are an attractive market for pellets because pellets are well-suited for this application and because western coal is not a competitor in the stoker market. Compliance stoker fuels come from locations such as Kentucky and West Virginia and the price for fuels from these locations is high relative to the current price of Illinois coal. This market offers the most attractive near-term economic environment for commercialization of pelletization technology. For this effort, we will be investigating the use of fines from two Illinois mines which currently mine relatively low-sulfur reserves and that discard their fines fraction (minus 100 mesh). The research will involve investigation of multiple unit operations including column flotation, filtration and pellet production. The end result of the effort will allow for an evaluation of the commercial viability of the approach.

    This study examines the role of physico-chemical mass transfer processes on the rate of biotransformation of polycyclic aromatic hydrocarbon (PAH) compounds released from non-aqueous phase liquid (NAPL) coal tar present at residual saturation within a microporous medium. A simplified coupled dissolution-degradation model is developed that describes the concurrent mass transfer and biokinetic processes occurring in the system. Model results indicate that a dimensionless Damkohler number can be utilized to distinguish between systems that are mass transfer limited, and those that are limited by biological phenomena. The Damkohler number is estimated from independent laboratory experiments that measure the rates of aqueous phase dissolution and biodegradation of naphthalene from coal tar. Experimental data for Stroudsburg coal tar imbibed within 236 {mu}m diameter silica particles yield Damkohler numbers smaller than unity, indicating, for the particular system under study, that the overall rate of biotransformation of naphthalene is not limited by the mass transfer of naphthalene from coal tar to the bulk aqueous phase. There is a need for investigation of mass transfer for larger particles and/or other PAH compounds, and study of microbial rate-limiting phenomena including toxicity, inhibition and competitive substrate utilization.

    The Department of Energy/Morgantown Energy Technology Center (DOE/METC) has initiated research on the disposal solid processes. The objective of this research is to develop information to be used by private industry and government agencies for planning waste disposal practices associated with advanced coal processes. To accomplish this objective, DOE has contracted Radian Corporation and the North Dakota Energy & Environmental Research Center (EERC) to design, construct, and monitor a limited number of field disposal tests with advanced coal process wastes. These field tests will be monitored over a three year period with the emphasis on collecting data on the field disposal of these wastes. Information on field disposal behavior is needed (a) as input to predictive models being developed, (b) as input to the development of rule of thumb design guidelines for the disposal of these wastes, and (c) as evidence of the behavior of these wastes in the natural environment.This study is organized into four major Tasks. Task 1 and 2 were devoted to planning the Task 3 field study. Task 4 uses the results of the field testing to produce an Engineering Design Manual for the utilities and industrial users who manage wastes from advanced coal combustion technologies.

    Work continued on the study of disposable catalysts and the effect of specific additives in both the SRC I and SRC II processing modes. At 450/sup 0/C, 2250 psig and 1.0 hour residence time with Loveridge coal in the SRC II mode, yields and hydrogen consumptions were essentially the same for runs with 5 wt % added pyrite or 3.3 wt % added ferric oxide. When Loveridge coal was impregnated with 0.7 wt % molybdenum, slightly higher oil yields and slightly lower hydrocarbon gas, SRC and IOM yields were obtained than with the iron compounds above. When Loveridge coal was processed in the SRC I mode at 450/sup 0/C, 1900 psig and 26 minutes residence time, there was a 3.7% increase in total oil yield with a corresponding decrease in SRC yield when pyrite was added to the feed slurry. There was a smaller effect with a FeS/sub 2//Fe/sub 2/O/sub 3/ combination and little or no effect when ferric oxide alone was added.

    Studies on the basic properties of supported sulfide catalysts showed that different supports have a profound influence on catalytic activities of CoMo catalysts. The three functions of hydrodesulfurization, hydrogenation and cracking were differently affected depending on the support used and the manner of preparation of the catalyst. Also, incorporation of additives to the support showed that the different catalytic functions can be selectively affected. A systematic study concerned with catalytic cracking of coal-derived liquids, viz., an SRC-II middle-heavy distillate and four hydrotreated SRC-II products was carried out in the range of 375 to 500/sup 0/C (LHSV, 0.2 to 3.9 h/sup -1/). Hydrotreatment, even to a limited extent, results in a remarkable improvement in the yield of gasoline-range products from the SRC-II distillate. This improvement is ascribed to: (a) hydrogenolysis reactions leading to lower molecular weight feedstock components and (b) limited hydrogenation of aromatic rings leading to polycyclic feed components with sufficient concentration of hydroaromatic rings needed for effective cracking. The results with model compounds and the data on hydrogen consumption during hydrotreatment of SRC-II liquids indicate that for tricyclic, tetracyclic, and pentacyclic coal-liquid components the optimal concentration of hydroaromatic rings for effective subsequent cracking is at least two rings per molecule.

    The objective Task 1, Synthesis of Propionates, is to develop the technology for the synthesis of low-cost propionates. These propionates are the basic feedstock for the subsequent reaction with formaldehyde to produce the target molecule, methyl methacrylate (MMA). Eastman has explored several possible routes to the propionates and has concluded that the most promising is the synthesis of propionic anhydride from the reaction of propionic acid from and ethylene (and also hydrogen in some cases). The main advantage of the anhydride over the acid is that its subsequent reaction with formaldehyde does not produce water, which can lead to undesired byproducts. Bechtel is carrying out a cost analysis of the Eastman route to the anhydride to determine if it is potentially competitive with commercially practiced routes to the same molecule. The answer is expected next quarter. The objective Task 2, Condensation Catalysis to develop catalysts for the condensation of the propionate (propionic anhydride is our target molecule) with formaldehyde. This reaction produces methacrylic acid (MAA), which would then be reacted with methanol to produce MMA in the slurry reactor. We have synthesized a wide range of catalysts and the results show that there is substantial byproduct formation, including 3-pentanone and some propionic acid. Our results show the highest yields of MAA using an alkalized alumina (1%Na/{sub y}-AI{sub 2}O{sub 3}). Although the condensation of propionic acid with formaldehyde is well studied in the literature, little is reported on the condensation of the anhydride. Although it is likely that the same general types of acid/base catalysts that promote the acid condensation will also promote that of the anhydride, the strength and balance of the acid and base sites is likely to be different. We plan to explore the relationship of the catalyst properties and MMA yields using the Altamira system, due to be delivered this next quarter.

    This research project is for the development of a technically and economically feasible process for drying and stabilizing of fine particles of high-moisture subbituminous coal. Research activities were initiated with efforts concentrating on characterization of the two feed coals: Eagle Butte coal from AMAX Coal Company's mine located in the Powder River Basin of Wyoming; and coal from Usibelli Coal Mine, Inc.'s mine located in central Alaska. Both of the feed coals are high-moisture subbituminous coals with ''as received'' moisture contents of 29% and 22% for the Eagle Butte and Usibelli coals, respectively. However, physical analyses of the crushed coal samples (--28-mesh particle size range) indicate many differences. The minimum fluidization velocity (MFV) of the feed coals were experimentally determined. The MFV for --28-mesh Eagle Butte coal is approximately 1 ft/min, and the MFV for --28-mesh Usibelli coal is approximately 3 ft/min. 2 refs., 16 figs., 3 tabs.

    There are substantial economic incentives to explore the possibility of converting boilers and other industrial processes from natural gas or oil to pulverized-fuel firing; however, such a change can have a considerable impact on the thermal performance of the system, due mainly to: fuel specific adiabatic flame temperatures; different flow and combustion patterns in the furnace; differences in the type and concentration of radiative species, especially particles, in the combustion products; and ash deposition on heat transfer surfaces. This program is concerned with the provision of a technology base to expedite the conversion of industrial processes from oil and gas to coal and other pulverized fuels. It addresses primarily the impact of fuel type on the thermal performance of a combustor. The program incorporates two experimental tasks and is constructed around an analytical task (Task 1) which will identify and upgrade a family of computer programs required to undertake thermal performance analysis studies. These analytical tools will thus be used to predict the effects of parameters such as fuel type and furnace variables on combustor performance, and to identify those properties which have a major impact on thermal performance. The second task uses a combustion reactor to screen the key variable identified in Task 1 and to provide data on the properties of coal particulate matter which affect heat transfer performance. Verification of the engineering analytical approach will be provided by measurements made in a pilot-scale furnace in the third task.

    Manganese-based sorbents have been investigated for the removal of hydrogen sulfide (the primary sulfur bearing compound) from hot coal gases prior to its use in combined cycle turbines. Four formulations of Mn-based sorbents were tested in an ambient-pressure fixed-bed reactor to determine steady state H{sub 2}S concentrations, breakthrough times and effectiveness of the sorbent when subjected to cyclic sulfidation and regeneration testing. In a previous report, the sulfidation results were presented. Manganese-based sorbents with molar ratios > 1:1 Mn:Substrate were effective in reducing the H{sub 2}S concentration in simulated coal gases to less than 100 ppmv over five cycles. Actual breakthrough time for formulation C6-2-1100 was as high as 73% of breakthrough time based on wt% Mn in sorbent. In this report, the regeneration results will be presented. Regeneration tests determined that loaded pellets can be fully regenerated in air/steam mixture at 750{degrees}C with minimal sulfate formation. 16 refs., 9 figs., 5 tabs.

    This report discusses a kinetic investigation of the Fe-S-H/sub 2/ system conducted as an outgrowth of current research in the SRC-I (solvent refined coal) process to better understand the effects of naturally occurring iron sulfides in coal hydrogenation and hydrodesulfurization. A total of twelve closed system reactions were carried out in which 48 to 60 mesh pyrite, in the presence of hydrogen gas, underwent transformation to 1C hexagonal pyrrhotite. Reaction temperatures were 350/sup 0/C and 400/sup 0/C with four sample runs at temperature. Initial pressure of hydrogen gas was 1250 psig (8617 KPa). A comparison of the results for each reaction series was evaluated with time and temperature as variables. The transformation rate of pyrite to pyrrhotite was found to increase over the range of reaction temperatures with the 400/sup 0/C samples showing the greatest amount of transformation per unit time. For the 375/sup 0/C and 400/sup 0/C runs pyrrhotite formation decreased after approximately 15 minutes of reaction time due to (1) reduced availability of pyrite, and (2) resistance to diffusion in the topochemical product layer.

    The overall objectives of this program are to investigate potential technologies for the conversion of coal-derived synthesis gas to oxygenated fuels, hydrocarbon fuels, fuel intermediates, and octane enhancers; and to demonstrate the most promising technologies at DOE`s LaPorte, Texas, Slurry Phase Alternative Fuels Development Unit (AFDU). BASF continues to have difficulties in scaling-up the new isobutanol synthesis catalyst developed in Air Products` laboratories. Investigations are proceeding, but the proposed operation at LaPorte in April is now postponed. DOE has accepted a proposal to demonstrate Liquid Phase Shift (LPS) chemistry at LaPorte as an alternative to isobutanol. There are two principal reasons for carrying out this run. First, following the extensive modifications at the site, operation on a relatively ``benign`` system is needed before we start on Fischer-Tropsch technology in July. Second, use of shift catalyst in a slurry reactor will enable DOE`s program on coal-based Fischer-Tropsch to encompass commercially available cobalt catalysts-up to now they have been limited to iron-based catalysts which have varying degrees of shift activity. In addition, DOE is supportive of continued fuel testing of LaPorte methanol-tests of MIOO at Detroit Diesel have been going particularly well. LPS offers the opportunity to produce methanol as the catalyst, in the absence of steam, is active for methanol synthesis.

    During this reporting period comparison was made between theoretical and actual biogas production in the upflow reactors, where Texas lignite (TxL) was loaded at 0% (control) and 10% solids loadings. Data for methane and total gas production from task 4 were used. Calculations were made on the assumption that Texas lignite contains 60% carbon and theoretically all of this carbon is converted to CH{sub 4} and CO{sub 2}. Analysis of the data obtained from the bioreactor experiments showed that higher biogas production is due to more efficient biogasification of Texas lignite in bioreactor with reethanol (Table 1) . As it was previously mentioned, methanol (at 0.5% concentration of the total volume of reactants) can be used as hydrogen donor for biogasification (data presented in the 10th Quarterly report). Data in Table 1 clearly indicates, that the theoretical CH{sub 4} and biogas production from methanol is negligible and net biomethanation of TxL is enhanced by the addition of methanol. Observation of high methane production in the reactor where Texas lignite was supplemented with methanol, supports our hypothesis that methanol acts as an additional hydrogen donor.

    The overall objective of the KRW coal gasification program is to demonstrate the viability of the KRW pressurized, fluidized-bed, gasification system for the production of medium-Btu fuel gas for syngas, electrical power generation, chemical feedstocks, or industrial fuels and to obtain performance and scaleup data for the process and hardware. Progress reports are presented for the following tasks: (1) operation and maintenance of the process development unit (PDU); (2) modifications to the PDU; (3) cold flow scaleup facility; (4) advanced process design and analysis; and (5) laboratory support studies. For laboratory support studies, coal and/or char fines from Wyoming Sub C, Western Kentucky, Republic of South Africa (RSA), and Pittsburgh seam coals processed in the PDU were characterized for reactivity on a thermogravimetric analyzer. The average relative reactivity of the fines (-120 x +140 mesh) was found to be nearly the same as that for larger size distribution (18 x 60 mesh, -1.0 + 0.25 mm). This is consistent with the observations of studies reported in literature on carbon gasification reactions.

    Two long gasification tests were accomplished (66 and 72 hours of slagging operation) this quarter, and the balance of the wastewater needed for the second cooling tower (CT) test (approx. 11,000 gallons) was generated. Eleven thousand gallons of slagging fixed-bed gasifier (SFBG) wastewater were solvent extracted and ammonia stripped (AS) to nominal levels of 160 mg/1 phenol and 600 mg/1 NH/sub 3/. This wastewater is being further treated by activated sludge (AS) and granular activated carbon (GAC) processing to prepare a high quality makeup for the second CT test. Phenol mass balances indicated that > 90 pct of the phenol was stripped from the tower, indicating that previous assumptions of high levels of biodegradation were erroneous. Over 80 pct of the ammonia and about 25 pct of the methanol were also stripped. Data collected during steady state operation of the bench-scale rotating biological contractor indicate complete removal of phenolics and alcohols, and 94 pct removal of BOD. Nitrification also occurred in this unit, with over 30 pct removal of ammonia. Problems due to individual bacteria, present in the biotreated wastewater, passing through the multi-media filter and thus decreasing the carbon adsorption efficiency of the GAC system, have resulted in lower treatment rates than originally anticipated. As a result, to achieve the desired treatment, the contact time of the wastewater with the carbon in the granular activated carbon system has been increased. Since this has decreased the treatment rate, a larger carbon adsorption system has been designed and is presently being constructed.

    The project objective is to design, construct, install, provide operator training and start-up a circulating fluidized bed combustion system at the Lebanon Pennsylvania Veteran`s Affairs Medical Center. This unit will co-fire coal and hospital waste providing inexpensive and efficient destruction of both general and infectious hospital waste and steam generation. The steam generated is as follows: (1) Steam = 20,000 lb/hr, (2) Temperature = 353 F (saturated), (3) Pressure = 125 psig, and (4) Steam quality ={approximately}98.5%. On February 3, 1995 DONLEE notified Lebanon VA and DOE-METC that additional funding would be required to complete the project. This funding, in the amount of $1,140,127, is needed to complete the facility, start-up and shakedown the facility, perform the test program and write the final report. On March 7, 1995 the vendors were notified that the Lebanon VA Steam Plant Project was shut down and that all work outside DONLEE was stopped pending obtaining additional funding.

    Calibrations for the determination of hydroxyl, primary amine, and secondary amine functional groups by infrared (IR) spectroscopy have been completed. The model compounds 1-naphthol, 1-aminonaphthalene, and carbazole were used for these calibrations. The IR analysis of the coal fluids is nearly complete. Elemental analysis of the samples is also proceeding and is nearing completion. Functional group contributions to ideal gas heat capacities and enthalpies were extended, based on model compounds, to low temperature regions. The functional group contributions were determined for temperatures ranging from 0 K to 1000 K. The results of the evaluation are tabulated for ideal gas heat capacity and enthalpy in Tables 2 and 3, respectively. The ideal gas heat capacity and enthalpy calculations were performed for pure compounds based on the following two cases: Case I. The ideal gas calorimetric properties were determined using functional group contributions by Benson's Method (Benson, 1968; Benson et al., 1969). Case II. The ideal gas calorimetric properties were determined using functional group contributions based on model compounds. A summary of the results is presented for ideal gas heat capacities and enthalpies. 3 refs., 5 figs., 5 tabs.

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

    Maximum methane production was obtained in the experimental vials that contained 0.2% SNTM supplemented with 10 mM sodium citrate and 1% TxL (144 cc), while in the control vials CH{sub 4} production was only 58 cc. The conversion efficiency was 24%. This clearly shows citrate to be an important mediator for the formation of acetate (main precursor for CH{sub 4} formation) in the glyoxylate cycle, on the one hand, and as a sequestering agent, on the other. These results further indicate that citrate can, be successfully used as co-substrate for enhancement of the TxL biogasification process. The results obtained reconfirmed our hypothesis that the metals (such as Fe{sup 3+}, Mn{sup 2+}, Mg{sup 2+}, CO{sup 2+}, Zr{sup 2+}, etc., present in the coal structure) are chelated/sequestered by the addition of citrate. Mass balance calculations show that this increase in CH{sup 4} production is due to the biomethanation of TxL and not because of the chemical conversion of co-substrate(s) to CH{sub 4} (Table 1). The effect of sodium citrate on biomethanation of TXL from the first experiment ``Effect of co-substrate addition No. 1`` was reconfirmed in this experiment. The peak in acetate concentration (1317 ppm) on day 7 was followed by a rapid conversion of this precursor to CH{sub 4} (Figure 16). The VFA data obtained from both experiments (``Effect of co-substrate addition No. 1 and No. 2``) confirms the hypothesis that citrate and methanol can significantly enhance the biomethanation of TxL (Figure 17).

    Residence time distributions (RTDs) were estimated by water tracing in a number of wet overflow ball mills (diameters 0.38 to 4.65 m) producing dense, coal-water slurries. In open-circuit mills of 0.38 m diameter and various length-diameter (LID) ratios, the mean residence times of solid were also determined from measured mill holdups. Holdup increased with increased mill feed rate, but the mean residence times of coal and water were still equal to each other. The experimental residence time distributions were fitted to the Mori-Jimbo-Yamazaki semi-infinite, axial mixing model, and the dimensionless mixing coefficient was determined for each of 25 tests in single- and two-compartment mills. This coefficient was found to be independent to the feed rate but linearly proportional to the D/L ratio. The mixing coefficient was smaller for two-compartment mills than for single-compartment mills, showing that there was reduced mixing introduced by the diaphragm separating the compartments. Equations are given to scale residence time distributions for changes in mill diameter and length.

    The Mulled Coal process was developed as a means of overcoming the adverse handling characteristics of wet fine coal without thermal drying. The process involves the addition of a low cost, harmless reagent to wet fine coal using off-the-shelf mixing equipment. Based on laboratory- and bench-scale testing, Mulled Coal can be stored, shipped, and burned without causing any of the plugging, pasting, carryback and freezing problems normally associated with wet coal. The objectives of this project are to demonstrate that: the Mulled Coal process, which has been proven to work on a wide range of wet fine coals at bench scale, will work equally well on a continuous basis, producing consistent quality at a convincing rate of production in a commercial coal preparation plant; the wet product from a fine coal cleaning circuit can be converted to a solid fuel form for ease of handling and cost savings in storage and rail car transportation; and a wet fine coal product thus converted to a solid fuel form, can be stored, shipped, and burned with conventional fuel handling, transportation, and combustion systems. During this reporting period, virtually all of the technical activities and progress was made in the areas of circuit installation and startup operations. Work in these activity areas are described.

    This report summarizes technical progress on the program “Distributed Fiber Optic Sensor for On-Line Monitoring of Coal Gasifier Refractory Health,” funded by the National Energy Technology Laboratory of the U.S. Department of Energy, and performed by the Center for Photonics Technology of the Bradley Department of Electrical and Computer Engineering at Virginia Tech. The scope of work entails analyses of traveling grating generation technologies in an optical fiber, as well as the interrogation of the gratings to infer a distributed temperature along the fiber, for the purpose of developing a real-time refractory health condition monitoring technology for coal gasifiers. During the project period, which is from 2011-2015, three different sensing principles were studied, including four-wave mixing (FWM), coherent optical time-domain reflectometer (C-OTDR) and Brillouin optical time-domain analysis (BOTDA). By comparing the three methods, the BOTDA was selected for further development into a complete bench-top sensing system for the proposed high-temperature sensing application. Based on the input from Eastman Chemical, the industrial collaborator on this project, a cylindrical furnace was designed and constructed to simulate typical gasifier refractory temperature conditions in the laboratory, and verify the sensor’s capability to fully monitor refractory conditions on the back-side at temperatures up to 1000°C. In the later stages of the project, the sensing system was tested in the simulated environment for its sensing performance and high-temperature survivability. Through theoretical analyses and experimental research on the different factors affecting the sensor performance, a sensor field deployment strategy was proposed for possible future sensor field implementations.

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

    To investigate the distribution of polycyclic aromatic hydrocarbons (PAHs) in fly ash, the combustion of coal and residual char was performed in a pressurized spouted fluidized bed. After Soxhlet extraction and Kuderna-Danish (K-D) concentration, the contents of 16 PAHs recommended by the United States Environmental Protection Agency (U.S. EPA) in coal, residual char, and fly ash were analyzed by a high-performance liquid chromatography (HPLC) coupled with fluorescence and diode array detection. The experimental results show that the combustion efficiency is lower and the carbon content in fly ash is higher during coal pressurized combustion, compared to the residual char pressurized combustion at the pressure of 0.3 MPa. Under the same pressure, the PAH amounts in fly ash produced from residual char combustion are lower than that in fly ash produced from coal combustion. The total PAHs in fly ash produced from coal and residual char combustion are dominated by three- and four-ring PAHs. The amounts of PAHs in fly ash produced from residual char combustion increase and then decrease with the increase of pressure in a fluidized bed. 21 refs., 1 fig., 4 tabs.

    This paper presented an experimental investigation on the estimation of radiative properties and temperature distributions in a 670 t/h coal-fired boiler furnace by a portable imaging processing system. The portable system has been calibrated by a blackbody furnace. Flame temperatures and emissivities were measured by the portable system and equivalent blackbody temperatures were deduced. Comparing the equivalent blackbody temperatures measured by the portable system and the infrared pyrometer, the relative difference is less than 4%. The reconstructed pseudo-instantaneous 2-D temperature distributions in two cross-sections can disclose the combustion status inside the furnace. The measured radiative properties of particles in the furnace proved there is significant scattering in coal-fired boiler furnaces and it can provide useful information for the calculation of radiative heat transfer and numerical simulation of combustion in coal-fired boiler furnaces. The preliminary experimental results show this technology will be helpful for the combustion diagnosis in coal-fired boiler furnaces. (author)

    The objective of this project is to study the effectiveness of a novel hydrophobic microorganism, Mycobacterium phlei (M. phlei), for the selective flocculation of coal from pyrite and ash forming minerals. During the reporting period, the hydrophobicity of different coal samples was studied both in the presence and absence of M. phlei cells. In the absence of M. Phlei, Illinois No. 6 and Pennsylvania No. 8 exhibited higher contact angles as compared to Kentucky No. 9 coal. All the coal samples exhibited a maximum in contact angle around pH 5--7, which roughly coincides with the iso-electric point (iep) of different coals studied in this investigation. In the presence of M. phlei, maximum contact angle shifted to lower pH range of 2--3 which coincides with the iep of the M. phlei. These measurements reinforce the notion that good flocculation of coal with M. phlei can be achieved around pH 2--3. The amount of soluble fraction released during rupturing of M. phlei cells was studied as a function of sonication time. The rupturing experiments showed that the whole cells (unruptured cells) contain nearly 40% by weight of soluble fractions. Also, during the reporting period, the fabrication of the counter-current flocculation device was completed.

    This report summarizes work completed to predict and measure optimum operating conditions for entrained coal gasifications processes. This study is the third in a series designed to investigate mixing and reaction in entrained coal gasifiers. A new team of graduate and undergraduate students was formed to conduct the experiments on optimum gasification operating conditions. Additional coal types, which will be tested in the gasifier were identified, ordered, and delivered. Characterization of these coals will be initiated. Hardware design modifications to introduce swirl into the secondary were initiated. Minor modifications were made to the gasifier to allow laser diagnostics to be made on an independently funded study with the Los Alamos Scientific Laboratory. The tasks completed on the two-dimensional model included the substantiation of a Gaussian PDF for the top-hat PDF in BURN and the completion of a Lagrangian particle turbulent dispersion module. The reacting submodel is progressing into the final stages of debug. The formulation of the radiation submodel is nearly complete and coding has been initiated. A device was designed, fabricated, and used to calibrate the actual Swirl Number of the cold-flow swirl generator used in the Phase 2 study. Swirl calibrations were obtained at the normal tests flow rates and at reduced flow rates. Two cold-flow tests were also performed to gather local velocity data under swirling conditions. Further analysis of the cold-flow coal-dust and swirl test results from the previous Phase 2 study were completed.

    The successful design of full-scale, open-cycle, coal-fired MHD generators for baseload electrical production requires a detailed understanding of the plasma chemical and plasma dynamic characteristics of anticipated combustor and channel fluids. Progress in efforts to model the efficiency of an open-cycle, coal-fired MHD channel based on the characterization of the channel flow as well as laboratory experiments to validate the modeling effort as detailed. In addition, studies related to understanding arcing phenomena in the vicinity of an anode are reported.

    1995-11-01

    The objective of this project is to demonstrate and evaluate commercially available selective catalytic reduction (SCR) catalysts from U.S., Japanese, and European catalyst suppliers on a high-sulfur U.S. Coal-fired boiler. SCR is a post-combustion nitrogen oxide (NO{sub x}) control technology that involves injecting ammonia into the flue gas generated from coal combustion in an electric utility boiler. The flue gas containing ammonia is then passed through a reactor that contains a specialized catalyst. In the presence of the catalyst, the ammonia reacts with NO{sub x} to form nitrogen and water vapor. Although SCR is widely practiced in Japan and European gas-, oil-, and low-sulfur coal-fired boilers, there are several technical uncertainties associated with applying SCR to U.S. coals. These uncertainties include: (1) potential catalyst deactivation due to poisoning by trace metal species present in U.S. coals that are not present in other fuels; (2) performance of the technology and effects on the balance-of-plant equipment in the presence of high amounts of SO{sub 2} and SO{sub 3}; performance of a wide variety of SCR catalyst compositions, geometries, and methods of manufacture under typical high-sulfur coal-fired utility operating conditions. These uncertainties are being explored by operating a series of small- scale SCR reactors and simultaneously exposing different SCR catalysts to flue gas derived from the combustion of high sulfur U.S. coal. The demonstration is being performed at Gulf Power Company`s Plant Crist Unit No. 5 (75 MW capacity) near Pensacola, Florida. The project is funded by the U.S. Department of Energy (DOE), Southern Company Services, Inc. (SCS on behalf of the entire Southern electric system), the Electric Power Research Institute (EPRI), and Ontario Hydro. SCS is the participant responsible for managing al aspects of this project. 1 ref., 69 figs., 45 tabs.

    An asphaltene-containing SRC-II coal liquid derived from Powhatan No. 5 mine coal and produced in the Ft. Lewis demonstration plant has been selected for study of catalytic hydroprocessing reactions. Analytical separation by liquid chromatography is being carried out to produce nine distinct fractions from 1 kg of coal liquid. These fractions will be used as feeds to high-pressure catalytic flow microreactors. Hydroprocessing of polynuclear aromatic hydrocarbons under industrially relevant conditions has shown that these are much more reactive than benzene. The reaction networks involve reversible hydrogenation and isomerization, and significant concentrations of hydroaromatic (hydrogen-donor) species are attainable under practical conditions. Hydroprocessing of solutions containing the following combinations of compounds has also been studied: quinoline/indole, quinoline/indole/dibenzothiophene, and quinoline/indole/naphthalene. Four of the types of compounds, or potential lumps, in coal-derived liquids are basic nitrogen, nonbasic nitrogen, sulfur, and aromatic compounds. It is desired to determine how these compounds interact and compete with each other in hydroprocessing and how these interactions depend on hydrogen partial pressure. Four model compounds, quinoline, indole, dibenzothiophene, and naphthalene, have been selected to represent compounds in each group. These compounds, in different proportions with hydrogen, were allowed to react in a batch autoclave reactor.

    All three of the CombiNO{sub x} NO{sub x} control technologies were performed simultaneously for the first time. Tests were performed while firing coal as the primary fuel, and natural gas and coal as reburn fuels. The results for the complete CombiNO{sub x} process for coal firing and natural gas reburning are displayed in Figure 3-1. NO/NO{sub x} measurements were taken with the new sample system. The filter and line were cleaned periodically throughout testing to avoid ash build-up; ash has also been shown to convert NO{sub 2} to NO. Reduction due to natural gas reburning was 54% with burnout air injected at a downstream location of approximately 1600{degree}F. Advanced Gas Reburning produced a 79% reduction -- although it is suspected that better reduction would have been possible if injection resolution in the furnace allowed the urea to be injected at a more optimum temperature of 1850{degree}F. The methanol injection step converted 45% of the existing NO to NO{sub 2}, achieving an overall CombiNO{sub x} NO reduction of 89%. The coal reburning CombiNO{sub x} test results are displayed in Figure 3-2. Results are similar to those obtained for natural gas reburning. Reduction due to urea injection was better while reburning with coal than for natural gas, probably due to the more optimum urea injection temperature. The methanol injection step converted 40% of the NO to NO{sub 2}, similar to the 45% NO conversion that occurred for natural gas reburning. An overall CombiNO{sub x} NO reduction of 93% was achieved, resulting in a final NO concentration of 61 ppM at 3% O{sub 2}.

    Removal of mineral matter from liquid hydrocarbons derived from the direct liquefaction of coal is required for product acceptability. Current methods include critical solvent de-ashing and filtration, both of which produce an ash reject stream containing up to 15% of the liquid hydrocarbon product. This program is directed towards development of an improved process for de-ashing and recovery of coal-derived residual oil: the use of ceramic membranes for high-temperature microfiltration and diafiltration. Using laboratory-scale ceramic membrane modules, samples of a coal-derived residual oil containing ash will be processed by crossflow microfiltration, followed by solvent addition and refiltration (diafiltration). Recovery of de-ashed residual oil will be demonstrated. Data from this program will be used to develop a preliminary engineering design and cost estimate for a demonstration pilot plant incorporating full-scale membrane modules. In addition, estimates for production system capital and operating costs will be developed to assess process economic feasibility. The five program tasks include (1) ceramic membrane fabrication, (2) membrane test system assembly, (3) testing of the ceramic membranes, (4) design of a demonstration system using full scale membrane modules, and (5) development of estimates for microfiltration capital and operating costs and assessment of process economic feasibility.

    Model compound reactions were studied to evaluate the effects of mass transfer, solvent type, solvent blending, hydrogen partial pressure, temperature, reactant concentration, additive loading and its preparation, etc. Naphthalene hydrogenation and benzothiophene hydrodesulfurization were investigated under the conditions comparable to commercial coal liquefaction and related processes. Both of these reaction systems were observed to be surface reaction controlled under the reaction conditions used in this work. Certain aromatic compounds were observed to cause a reduction in the reaction rates of naphthalene and benzothiophene. Single stage coal dissolution was investigated using tetralin as a hydrogen donor solvent and a commercial cobalt-molybdate catalyst. A spinning basket system was developed to allow injection of the catalyst at a desired time in the reaction cycle. This catalyst injection technique proved to be reliable for the exploratory work done here. The degree of catalyst deactivation was rated by comparing the activities of the spent catalyst for model compound (naphthalene and cumene) reactivities relative to those of the fresh catalyst. No substantial reduction in deactivation was observed to result with delayed contacting of the catalyst with the coal-tetralin reaction mixture. The effect of reaction temperature on the initial rate of catalyst deactivation was also studied.

Lewis demonstration plant has been selected for study of catalytic hydroprocessing reactions. Analytical separation by liquid hydroprocessing reactions. Analytical separation by liquid chomatography has been carried out to produce nine distinct fractions from 1 kg of coal liquid. These have been further separated into compound classes and characterized in detail by elemental analysis, mass spectrometry, NMR, and infrared spectroscopy. Compounds typical of each fraction (except asphaltenes) have been designed. Hydroprocessing of polynuclear aromatic hydrocarbons under industrially relevant conditions has shown that these are much more reactive than benzene. The reaction networks involve reversible hydrogenation and isomerization, and significant concentrations of hydroaromatic (hydrogen-donor) species are attainable under practical conditions. Hydroprocessing of solutions containing the following combinations of compounds has also been studied: quinoline/indole, quinoline/indole/dibenzothiophene, and quinoline/indole/naphthalene. Lumping of components in a reaction network simplifies the kinetics determination of fuel feedstocks. Component lumping simulations involving first-order kinetics were successfully carried out for certain schemes in the quinoline network. This network can be represented by 3 simplified components. The quinoline and indole reaction networks are assumed to be made up of 4 lumps with the adsorption constants fixed, the intrinsic kinetic constants were recovered, and the lumping proved successful.

    An asphaltene-containing SRC II coal liquid from the Ft. Lewis demonstration plant has been selected for study of catalytic hydroprocessing reactions. Analytical separation of the liquid by liquid chromatography will be used to produce nine distinct fractions. These will be prepared from 1 kg of coal liquid and used individually as feeds to high-pressure flow microreactors. Hydroprocessing of polynuclear aromatic hydrocarbons under industrially relevant conditions has shown that they are much more reactive than benzene. The reaction networks involve reversible hydrogenation and isomerization, and significant concentrations of hydroaromatic (hydrogen-donor) species are attainable under practical conditions. Scanning electron microscopy combined with catalytic activity measurements (in hydroprocessing of dibenzothiophene and of quinoline) were used to characterize deactivated and regenerated Ni-Mo/Al/sub 2/O/sub 3/ catalysts (aged in the hydroprocessing of coal-derived liquids). EDAX results determined chemical composition of the catalyst and the deposited mineral crust. The hydroprocessing results indicate that regeneration of the catalysts can recover much of the activity lost as a result of coke formation.

    The objective of this contract is to investigate the removal of SO{sub x} and particulate matter from direct coal-fired combustion gas streams at high temperature and high pressure conditions. This investigation will be accomplished through a bench-scale testing and evaluation program employing sorbent mixed with a coal-water slurry for SO{sub x} removal, and an innovative particulate control concept. The particulate control device utilizes electrostatic agglomeration followed by a high efficiency mechanical collector (cyclone). The process goal is to achieve particulate collection efficiency better than that required by the 1979 new source performance standards. An additional goal is to demonstrate 70% SO{sub x} removal efficiency. This research project is now in the second of a 3 phase (Phase II) project. Phase II is to fabricate the combustor and particulate control devices and install the system at a test facility located at Research-Cottrell`s, KVB Western Laboratory, Santa Ana, CA. There are three functional categories, or tasks which are to be completed in sequence. These tasks are itemized as follows: Design, procurement, and installation; Shakedown and startup; Reporting. Attempts to validate the concept of electrostatic agglomeration were not possible in the shakedown program before budget constraints halted the program. What was learned was that electrostatic precipitation is feasible in the temperature range of 1600--1800{degrees}F and at pressures above 10 atmospheres.

    The complete CombiNO{sub x}, process has now been demonstrated at a level that is believed to be representative of a full-scale boiler in terms of mixing capabilities. A summary of the results is displayed in Figure 5-1. While firing Illinois Coal on the Reburn Tower, Advanced Reburning was capable of reducing NO{sub x}, by 83 percent. The injection of methanol oxidized 50--58 percent of the existing NO to N0{sub 2}. Assuming that 85 percent of the newly formed N0{sub 2} can be scrubbed in a liquor modified wet-limestone scrubber, the CombiNO{sub x}, process has been shown capable of reducing NO{sub 2}, by 90--91 percent in a large pilot-scale coal-fired furnace. There is still uncertainty regarding the fate of the N0{sub 2} formed with methanol injection. Tests should be conducted to determine whether the reconversion is thermodynamic or catalytic, and what steps can be taken (such as quench rate) to prevent it from happening.

    The objective was to establish the reaction network for the catalytic hydroconversion of a simple compound representative of the organic-oxygen compounds in coal liquids, namely 1-naphthol. The catalyst was a typical commercial, sulfided NiO-MoO/sub 3//..gamma..-Al/sub 2/O/sub 3/, and experiments were carried out with liquid-phase reactants in a stirred batch reactor under conditions approaching those of practical practice. The results summarized by the network of Figure 3 demonstrate that aromatic ring hydrogenation and direct oxygen extrusion (HDO) occur in parallel, as in the dibenzofuran/H/sub 2/ network. The pattern is akin to that observed in catalytic hydroprocessing of organosulfur compounds such as dibenzothiophene and benzo(b)naphtho-(2,3-d)thiophene. The pattern is different from that observed in catalytic hydroprocessing of organonitrogen compounds such as quinoline - in which extensive aromatic ring hydrogenation procedes C-N bond breaking.

    Work focused on establishing experimentally determined parameters for ultrasonic comminution and their translation into the design of an ultrasonic comminution array for Phase I testing. Early work indicated that continuous removal of fines during communition could significantly increase the production of -10 micron particles. Similarly, varying the mechanical gain of the ultrasonic comminution apparatus and thereby increasing the strain amplitude of the system was shown to enhance fines production. A gain of 3:1 (i.e., a three-fold increase in strain amplitude) produced the best results. These features used with an ultrasonic cylinder segment apparatus resulted in 276% increase in the production of -10 micron fines over that generated by passing coal through a non-activated control. Thus influenced, the design of the Phase I ultrasonic comminution apparatus will incorporate both a dual-roll and roller/plate capability; it will provide continuous flow of particles through the region of ultrasonic activation, thus permitting removal of fines as they are comminuted; and will function with a gain of 3:1. The Phase I apparatus also offers the flexibility of operating with either traveling or standing ultrasonic waves. Varying the physical configuration (dual-roller or roller plate) and the mode of ultrasonic activation (traveling or standing wave) allows for cost effective testing of four different techniques. Additionally, operating frequency has been reduced to 15 kHz to permit use of off-the-shelf hardware in apparatus assembly and thus expedite testing. Selection of four representative, well-characterized coals has been completed; after initial testing, 200 lb. quantities of two of the samples will be secured for Phase II experimentation.

    Maintenance and laboratory calibrations were obtained for automatic recording methanometers for use during in-mine tests. Speecifications and quotations have been obtained for battery operated versions of the automatic recording methanometers for monitoring in the tailgate region of the longwall operation. Due to mine closings, meetings with mine operators to discuss in-mine testing and to observe the mining section to be monitored have been delayed until February 1983. Assuming a resumption of coal production, actual in-mine tests are tentatively scheduled for March, 1983. Development and testing of software modules for a general two-dimensional model has continued with good progress. The major work emphasis is on the efficient computer execution of the numerical algorithms. Preliminary simulation test runs of an isolated, unstimulated well in an isotropic, homogeneous coalbed have been made. Work has been initiated on incorporating an infinite conductivity fracture in the simulation. Graphical representation of the data generated from the two-dimensional model will be produced and verified. A request was initiated for a no-cost, six-minths extension; this request has subsequently been approved. There is no change in the contract objectives or technical approach, and the project is on target with respect to expenditures.

    Considerable effort has been devoted to checking and verifying some of the preliminary data reported previously. The technique employed in the past for measuring the x-ray transmission of the samples has been modified to provide more accurate values of the transmission. These transmission measurements are important for quantitative interpretation of the scattering data both because they are needed to determine the amount of background scattering that must be subtracted from a measured scattering curve and also because the value of the transmission is required for calculating the specific surface from the scattering data. Previous determinations of the specific surface have been checked and modified when corrected transmission values made recalculation necessary. Evaluation of the specific surface from the scattering data also requires a measurement of the absolute scattered intensity, or scattering cross section. In other words, the fraction of the incident radiation which is scattered must be known. For this scattering investigation of coals, the absolute intensity for the scattering system was determined by measurement of the scattering from a colloidal silica suspension. The details of this technique are described by I.S. Patel and P.W. Schmidt, J. Appl. Cryst. 4, 50 to 55. (1971).

    Contract objectives are: development of a one-step liquid phase dimethyl ether/methanol process; and investigation of the potential of liquid phase synthesis of alternative fuels from coal-derived synthesis gas. Definition of Preferred Catalyst System was completed after several commercial methanol catalysts and dehydration catalysts were tested. BASF S3-86 and Catapal gamma alumina is the preferred catalyst system of choice. Process Variable Scans on the Preferred Catalyst System was started with Shell gas. Data were obtained at various pressures (750 to 1400 psig), temperatures (250 to 280{degrees}C), and space velocities (5000 to 9000 sl/kg-hr). Increase in system pressure seems to have a very significant benefit to both DME and methanol formation. Both Texaco and Shell gases were evaluated. A ``stoichiometric`` feed composition (50% CO, 50% H{sub 2}) that yields maximum DME productivity at equilibrium was evaluated with a fresh batch of the optimum catalyst system. Productivities with the ``stoichiometric`` gas were much higher compared to Shell or Texaco gas. Following that test, Dow gas was evaluated (41% CO, 41% H{sub 2}, 16% CO{sub 2} and 2% N{sub 2}) using the same catalyst to study the effect of CO{sub 2}. Three DME/MEOH (1--4% DME) mixtures were evaluated by SWRI for their fuel properties. Results indicate that, with small amounts of DME added, significant improvements in both flash point and RVP are possible over the properties of LaPorte MEOH. the slurry-phase dehydration of alcohols to ethers was investigated by feeding 10 mol% mixed alcohols in N{sub 2} over an alumina catalyst suspended in mineral oil. Two alcohol mixture compositions were chosen for this study. One mixture contained methanol, ethanol, and 1-propanol in proportions representative of those in IFP Substifuel, while the other mixture contained methanol, ethanol, and isobutanol in proportions representative of those in Lurgi Octamix. 21 figs., 13 tabs.

  5. Mild coal pretreatment to improve liquefaction reactivity

    SciTech Connect (OSTI)

    Miller, R.L.

    1991-01-01

    This report describes work completed during the fourth quarter of a three year project to study the effects of mild chemical pretreatment on coal dissolution reactivity during low severity liquefaction or coal/oil coprocessing. The overall objective of this research is to elucidate changes in the chemical and physical structure of coal by pretreating with methanol or other simple organic solvent and a trace amount of hydrochloric acid and measure the influence of these changes on coal dissolution reactivity. This work is part of a larger effort to develop a new coal liquefaction or coal/oil coprocessing scheme consisting of three main process steps: (1) mile pretreatment of the feed coal to enhance dissolution reactivity and dry the coal, (2) low severity thermal dissolution of the pretreated coal to obtain a very reactive coal-derived residual material amenable to upgrading, and (3) catalytic upgrading of the residual products to distillate liquids.

    This work is a fundamental study of catalytic pretreatments as a potential preconversion step to low-severity liquefaction. The ultimate goal of this work is to provide the basis for the design of an improved liquefaction process and to facilitate our understanding of those processes that occur when coals are initially dissolved. The main objectives of this project are to study the effects of low-temperature pretreatments on coal structure and their impacts on the subsequent liquefaction. The effects of pretreatment temperatures, catalyst type, coal rank and influence of solvent will be examined. We have made significant progress in the following four aspects during this quarterly period: (1) influence of drying and oxidation of coal on the conversion and product distribution in catalytic liquefaction of Wyodak subbituminous coal using a dispersed catalyst; (2) spectroscopic characterization of dried and oxidized Wyodak coal and the insoluble residues from catalytic and thermal liquefaction; (3) the structural alteration of low-rank coal in low-severity liquefaction with the emphasis on the oxygen-containing functional groups; and (4) effects of solvents and catalyst dispersion methods in temperature-programmed and non-programmed liquefaction of three low-rank coals.

    Coal Technology Corporation (CTC) believes that the new CTC high gravity, high production, batch type centrifugal dryer technology can play a significant role in improving the product quality as well as costs of operation in coal processing plants. It is further believed that the new centrifugal dryer technology can form an important part in systems used to clean up the millions of tons of coal fines in refuse piles and ponds. It is anticipated that the new centrifuge can become an important ancillary to the advanced deep cleaning processes for coal. Because of these convictions, CTC has been engaged in a pioneering research effort into the new art of drying fine clean coal in high gravity, high production, batch type centrifuges, since 1981. This work has progressed to the point where the new centrifugal dryer technology is nearly ready for commercialization. It promises to provide needed fine coal drying capability at somewhat lower capital costs and at substantially lower operating costs than competitive systems. It also promises to do so with no detrimental effects on either the coal quality or the evironment. The primary objective of this project is to prove the concept in a commercial coal processing plant environment. The proof of concept tests will also include testing with a variety of coals from different regions. A further objective will be to optimize the efficiency and the cost effectiveness of the new centrifugal dryer technology.

    The objective of this research is to develop a mechanistic understanding of the oxidation of coal and coal pyrite, and to correlate the intrinsic physical and chemical properties of these minerals, along with changes resulting from oxidation, with those surface properties that influence the behavior in physical cleaning processes. The results will provide fundamental insight into oxidation, in terms of the bulk and surface chemistry, the microstructure, and the semiconductor properties of the pyrite. During the eighth quarter, wet chemical and dry oxidation tests were done on Upper Freeport coal from the Troutville [number sign]2 Mine, Clearfield County, Pennsylvania. In addition electrochemical experiments were done on electrodes prepared from Upper Freeport coal pyrite and Pittsburgh coal pyrite samples provided by the US Bureau of Mines, Pittsburgh Research Center, Pennsylvania.

    Coal production in the United States in 1991 declined to a total of 996 million short tons, ending the 6-year upward trend in coal production that began in 1985. The 1991 figure is 33 million short tons below the record level of 1.029 billion short tons produced in 1990 (Table 1). Tables 2 through 33 in this report include data from mining operations that produced, prepared, and processed 10,000 or more short tons during the year. These mines yielded 993 million short tons, or 99.7 percent of the total coal production in 1991, and their summary statistics are discussed below. The majority of US coal (587 million short tons) was produced by surface mining (Table 2). Over half of all US surface mine production occurred in the Western Region, though the 60 surface mines in this area accounted for only 5 percent of the total US surface mines. The high share of production was due to the very large surface mines in Wyoming, Texas and Montana. Nearly three quarters of underground production was in the Appalachian Region, which accounted for 92 percent of underground mines. Continuous mining methods produced the most coal among those underground operations that responded. Of the 406 million short tons, 59 percent (239 million short tons) was produced by continuous mining methods, followed by longwall (29 percent, or 119 million short tons), and conventional methods (11 percent, or 46 million short tons).

    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.

    Curtis, C.W.; Guin, J.A.; Tarrer, A.R.

    1984-01-01

    The objective of this research is to determine the feasibility of using heavy petroleum crudes and residua as solvents in coal liquefaction. Petroleum residuum is a hydrogen-rich material and coal is hydrogen deficient. In coprocessing, the fundamental concept being evaluated is to determine if petroleum residua can transfer hydrogen directly to coal at specified reaction conditions. The reaction parameters for such a transfer must be determined and optimized. Secondly, the idea of modifying the petroleum residua to produce more effective solvents for transferring hydrogen to coal during liquefaction is being evaluated. The goal of the coprocessing is to increase the net yield and improve the quality of liquid product compared to that originally present in the petroleum residuum. The parametric evaluation has shown that optimal conditions for combined processing are: Reaction Tempperature - 425/sup 0/C; Hydrogen Pressure - above 500 psia initial hydrogen pressure; Time - 90 minutes; and Catalyst - powdered hydrogenation catalyst. Coal conversion and oil production from combined catalytic (powdered) processing compare favorably with that from tetralin with a powdered catalyst. An added benefit of combined processing is the upgrading of the petroleum crude which is obtained during processing. Comparison of the final oil yields to the initial charge shows that combined processing yields a net increase of 23.3% for 90 minute reaction time while tetralin provides a net increase of 17.7% for 30 minutes of reaction. 3 figures, 20 tables.

    1990-01-01

    The objective of this research project is to understand the fundamentals involved in the flotation and flocculation of coal and oxidized coals and elucidate mechanisms by which surface interactions between coal and various reagents enhance coal beneficiation. An understanding of the nature of the heterogeneity of coal surfaces arising from the intrinsic distribution of chemical moieties is fundamental to the elucidation of mechanism of coal surface modification and its role in interfacial processes such as flotation, flocculation and agglomeration. A new approach for determining the distribution in surface properties of coal particles was developed in this study and various techniques capable of providing such information were identified. Distributions in surface energy, contact angle and wettability were obtained using novel techniques such as centrifugal immersion and film flotation. Changes in these distributions upon oxidation and surface modifications were monitored and discussed. An approach to the modelling of coal surface site distributions based on thermodynamic information obtained from gas adsorption and immersion calorimetry is proposed. Polyacrylamide and dodecane was used to alter the coal surface. Methanol adsorption was also studied. 62 figs.

    1995-12-31

    The objective of this research is to determine the relationship between the size and shape of coal and petroleum macromolecules and their diffusion rates i.e., effective diffusivities, in catalyst pore structures. That is, how do the effective intrapore diffusivities depend on molecule configuration and pore geometry. The research is divided into the following tasks: (1) relationship between effective intrapore diffusion coefficients, molecular size and pore geometry; (2) effects of solvent composition, solute concentration, and temperature on the molecular configuration and diffusion rate of coal and petroleum asphaltenes in catalysts pore; and (3) assessment of diffusional limitations in aged catalysts. This quarter, the GPC column efficiency was rechecked by using acetone injection. The calibration curve for the GPC was rechecked through polystyrene standards with narrow molecular weight distributions. Some experiments on adsorption and diffusion of coal asphaltenes through porous catalysts were performed. The asphaltenes were grouped into nine fractions with the concentration being determined via GPC. It was found that the uptake rate for one asphaltene fraction is different from those for other fractions. Comparison of experimental uptake data shows a difference in hindered diffusion behavior between petroleum asphaltenes and coal asphaltenes.

    1993-08-01

    A concept for an advanced coal-fired combined-cycle power generating system is currently being developed. The first phase of this three-phase program consists of conducting the necessary research and development to define the system, evaluating the economic and technical feasibility of the concept, and preparing an R&D plan to develop the concept further. The system proposed to meet these goals is a combined-cycle system where air for a gas turbine is indirectly heated to approximately 1800{degree}F in furnaces fired with coal-derived fuels and then directly heated in a natural-gas-fired combustor to about 2400{degree}F. The system is based on a pyrolyzing process that converts the coal into a low-Btu fuel gas and char. The fuel gas is relatively clean, and it is fired to heat tube surfaces that are susceptible to corrosion and problems from ash deposition. In particular, the high-temperature air heater tubes, which will need to be a ceramic material, will be located in a separate furnace or region of a furnace that is exposed to combustion products from the low-Btu fuel gas only.

    The technical objectives of this project are: To identify the partitioning of inorganic coal constituents among vapor, submicron fume, and fly ash products generated during the combustion of pulverized coal under a variety of combustion conditions. Fuel lean and fuel rich combustion conditions will be considered. To identify and quantify the fundamental processes by which the transformations of minerals and organically-associated inorganic species occur. Emphasis will be placed on identifying any changes that occur as a result of combustion under sub-stoichiometric combustion conditions. To incorporate the effects of combustion stoichiometry into an Engineering Model for Ash Formation based upon the understanding developed in (a) and (b). When completed, this model wig predict the particle size and chemical composition distributions of ash formed during the combustion of pulverized coal under a broad range of conditions. The work discussed in this report highlights the accomplishments of the second quarter of this two year project. This includes the final selection of coals by PSI PowerServe, the results of initial in-situ XAFS combustion measurements by the University of Kentucky, a review of the status of ash formation and deposition models by MIT, modeling of iron behavior during coal combustion by the University of Arizona, preliminary work on the redistribution of minerals within char during the early stages of combustion by PSI PowerServe, and the incorporation of a char fragmentation mechanism into the ash formation model by PSI PowerServe.

    This project was divided into two parts. One part evaluated possible catalysts for producing higher-alcohols (C{sub 2} to C{sub 5+}) as fuel additives. The other part provided guidance by looking both at the economics of mixed-alcohol production from coal-derived syngas and the effect of higher alcohol addition on gasoline octane and engine performance. The catalysts studied for higher-alcohol synthesis were molybdenum sulfides promoted with potassium. The best catalysts produced alcohols at a rate of 200 g/kg of catalyst/h. Higher-alcohol selectivity was over 40%. The hydrocarbon by-product was less than 20%. These catalysts met established success criteria. The economics for mixed alcohols produced from coal were poor compared to mixed alcohols produced from natural gas. Syngas from natural gas was always less expensive than syngas from coal. Engine tests showed that mixed alcohols added to gasoline significantly improved fuel quality. Mixed-alcohols as produced by our catalysts enhanced gasoline octane and decreased engine emissions. Mixed-alcohol addition gave better results than adding individual alcohols as had been done in the 1980's when some refiners added methanol or ethanol to gasoline.

    The hearing was called to review Senate bill S.801 which would provide Federal eminent domain authority for coal slurry pipelines to facilitate the national distribution and utilization of coal. Obtaining rights-of-way for the pipelines, particularly across railroad lands, has been a major stumbling lock to construction in the US. Testimony was heard from 9 witnesses, representing the Building and Construction Trade Department of AFL-CIO, Snamprogetti USA, Association of American Railroads, Railway Labor Executives Association, Coal and Slurry Technology Association, American Mining Congress, Edison Electric Institute, and the state of Louisiana. An attorney at law also gave testimony. Additional material was submitted by the National Association of Regulatory Utility Commissioners, the American Farm Bureau Federation, American Public Power Association, several union representatives, and the National Rural Electric Cooperative Association.

  16. Iron catalyzed coal liquefaction process

    Garg, Diwakar; Givens, Edwin N.

    1983-01-01

    A process is described for the solvent refining of coal into a gas product, a liquid product and a normally solid dissolved product. Particulate coal and a unique co-catalyst system are suspended in a coal solvent and processed in a coal liquefaction reactor, preferably an ebullated bed reactor. The co-catalyst system comprises a combination of a stoichiometric excess of iron oxide and pyrite which reduce predominantly to active iron sulfide catalysts in the reaction zone. This catalyst system results in increased catalytic activity with attendant improved coal conversion and enhanced oil product distribution as well as reduced sulfide effluent. Iron oxide is used in a stoichiometric excess of that required to react with sulfur indigenous to the feed coal and that produced during reduction of the pyrite catalyst to iron sulfide.

    The Coal Repository Project was initiated in 1980 by the Department of Energy/Pittsburgh Energy Technology Center to provide a centralized system for the collection of well characterized coal samples, and distribution to organizations involved in the chemical beneficiation of coal and related research. TRW Energy Development Group, together with its subcontractor Commercial Testing and Engineering Company, established the Coal Repository at the TRW Capistrano Chemical Facility, which is the location of the DOE-owned Multi-Use Fuel and Energy Processes Test Plant (MEP). Twenty tons each of three coals (Illinois No. 6, Kentucky No. 11 (West), and Pittsburgh No. 8 (from an Ohio mine)) were collected, characterized, and stored under a nitrogen atmosphere. Ten tons of each coal are 3/8-inch x 0, five tons of each are 14-mesh x 0, and five tons of each are 100-mesh x 0. Although TRW was within budget and on schedule, Department of Energy funding priorities in this area were altered such that the project was terminated prior to completion of the original scope of work. 9 figures, 3 tables.

    Production levels on each furnace exceeded 7000 NTHM/day during July. The combined production of 14,326 was a result of lower coke rates and below average delay rates on both furnaces, The combined production was at its highest level since September 1997. In August, the combined productivity declined to less than 13,500 NTHM/day. Although D furnace maintained a production rate in excess of 7000 NTHM/day, C furnace was lower because of a castfloor breakout and subsequent five day repair from August 26-30. Despite the lower productivity in August, injected coal and furnace coke rates were very good during the month. During September, the operation was difficult as a result of higher delays on both furnaces. The combined average monthly delay rate was considerably above the twenty-month average of 113 minutes per day and the combined average monthly production was less than 14,000 NTHM/day. Higher furnace coke rates at lower coal injection levels also contributed to the decrease. Additionally, the coke rate on both furnaces was increased substantially and the injected coal rate was decreased in preparation for the high volatile Colorado coal trial that started on September 28. The furnace process results for this quarter are shown in Tables 1A and 1B. In addition, the last twelve months of injected coal and coke rates for each furnace are shown in Figures 1 and 2.

    During the first quarter of 1990, work was carried out in the microautoclave, microreactor, and Bench-Scale units. An economics analysis on sub-bituminous coal processing at two space velocities was also completed. Several supported catalysts and a sample of iron oxide were screened in the microautoclave unsulfided and sulfided with DMDS and TNPS. A second shipment of Black Thunder coal from Wilsonville, oil agglomerated cleaned Illinois {number sign}6 coal from Homer City, OTISCA cleaned coal a New Mexico coal were evaluated for relative conversions with and without catalyst. Results of Bench-Scale developments with cleaned, oil agglomerated, Illinois {number sign}6 coal from Homer City(CC-6), Dispersed Catalyst/Supported Catalyst Two-Stage and reversed sequential operation (CC-7), on Black Thunder Coal (CC-7), and preliminary observations on OTISCA cleaned coal are presented. The oil agglomerated cleaned coal gave higher conversion and distillate production than the OTISCA cleaned coal. The Dispersed/Supported Two-Stage operation yielded higher gas production than the reverse sequence but also showed the higher coal conversion. Economic analysis of sub-bituminous coal processing at two space velocities showed a 3% higher return on investment with a 50% increase in space velocity. 13 tabs.

  8. The effect of turbulence on the stability of liquid jets and the resulting droplet size distributions. Third quarterly technical report, July 1, 1993--September 30, 1993

    Mansour, A.; Chigier, N.

    1993-12-01

    Laminar and turbulent columns of liquids issuing from capillary tubes were studied in order to determine the effects of turbulence on the stability of liquid jets and to establish the influence of liquid turbulence on droplet size distributions after breakup. Two capillary tubes were chosen with diameters D{sub 1}=3.0mm and D{sub 2}=1.2mm; jet Reynolds numbers were 1000--30000, and 400--7200. For water injection into stagnant air, stability curve is bounded by a laminar portion, where a jet radius and {delta}{sub o} initial disturbance amplitude, and a fully developed turbulent portion characterized by high initial disturbance amplitude (ln(a/{delta}{sub o,T}) {approximately} 4.85). In the transition region, ln(a/{delta}{sub o}) is not single valued; it decreases with increasing Reynolds number. In absence of aerodynamic effects, turbulent jets are as stable as laminar jets. For this breakup mode turbulence propagates initial disturbances with amplitudes orders of magnitude larger than laminar jets ({delta}{sub o,T}=28{times}10{sup 6} {delta}{sub o,L}). Growth rates of initial disturbances are same for both laminar and turbulent columns with theoretical Weber values. Droplet size distribution is bi-modal; the number ratio of large (> D/2), to small (< D/2) droplets is 3 and independent of Reynolds number. For laminar flow optimum wavelength ({lambda}{sub opt}) corresponding to fastest growing disturbance is equal to 4.45D, exactly the theoretical Weber value. For turbulent flow conditions, the turbulent column segments. Typically, segments with lengths of one to several wavelengths, detach from the liquid jet. The long ligaments contract under the action of surface tension, resulting in droplet sizes larger than predicted by Rayleigh and Weber. For turbulent flow conditions, {lambda}{sub opt} = 9.2D, about 2 times the optimum Weber wavelength.

    1999-07-30

    The Clean Air Act Amendments of 1990 identify a number of hazardous air pollutants (HAPs) as candidates for regulation. Should regulations be imposed on HAP emissions from coal-fired power plants, a sound understanding of the fundamental principles controlling the formation and partitioning of toxic species during coal combustion will be needed. With support from the Federal Energy Technology Center (FETC), the Electric Power Research Institute, and VTT (Finland), Physical Sciences Inc. (PSI) has teamed with researchers from USGS, MIT, the University of Arizona (UA), the University of Kentucky (UK), the University of Connecticut (UC), the University of Utah (UU) and the University of North Dakota Energy and Environmental Research Center (EERC) to develop a broadly applicable emissions model useful to regulators and utility planners. The new Toxics Partitioning Engineering Model (ToPEM) will be applicable to all combustion conditions including new fuels and coal blends, low-NOx combustion systems, and new power generation plants. Development of ToPEM will be based on PSI's existing Engineering Model for Ash Formation (EMAF). This report covers the period from 1 April 1999 to 30 June 1999. During this quarter low temperature ashing and elemental analysis of the three Phase II coals were completed. Results from MIT and USGS are comparable. Plans were made for measurements of loss of trace elements during devolatilization and for single particle combustion studies at the University of Utah. The iodated charcoal trap was tested on coal combustion flue gas and was shown to collect both Hg and Se in from the vapor phase with 100% efficiency. Data from the University of Arizona self-sustained combustor were analyzed from the combustion of three coals: Ohio, Wyodak and Illinois No. 6. Ash size distributions and enrichment factors for selected trace elements were calculated. The correlation between the concentration of the more volatile trace elements in the ash and the

    The U.S. Department of Energy and ADA Environmental Solutions are engaged in a project to develop commercial flue gas conditioning additives. The objective is to develop conditioning agents that can help improve particulate control performance of smaller or under-sized electrostatic precipitators on utility coal-fired boilers. The new chemicals will be used to control both the electrical resistivity and the adhesion or cohesivity of the fly ash. There is a need to provide cost-effective and safer alternatives to traditional flue gas conditioning with SO{sub 3} and ammonia. During this reporting quarter, performance testing of flue gas conditioning was underway at the PacifiCorp Jim Bridger Power Plant. The product tested, ADA-43, was a combination resistivity modifier with cohesivity polymers. This represents the first long-term full-scale testing of this class of products. Modifications to the flue gas conditioning system at Jim Bridger, including development of alternate injection lances, was also undertaken to improve chemical spray distribution and to avoid spray deposition to duct interior surfaces. Also in this quarter, a firm commitment was received for another long-term test of the cohesivity additives. This plant fires a bituminous coal and has opacity and particulate emissions performance issues related to fly ash re-entrainment. Ammonia conditioning is employed here on one unit, but there is interest in liquid cohesivity additives as a safer alternative.

    COALPREP assesses the degree of cleaning obtained with different coal feeds for a given plant configuration and mode of operation. It allows the user to simulate coal preparation plants to determine an optimum plant configuration for a given degree of cleaning. The user can compare the performance of alternative plant configurations as well as determine the impact of various modes of operation for a proposed configuration. The devices that can be modelled include froth flotationmore » devices, washers, dewatering equipment, thermal dryers, rotary breakers, roll crushers, classifiers, screens, blenders and splitters, and gravity thickeners. The user must specify the plant configuration and operating conditions and a description of the coal feed. COALPREP then determines the flowrates within the plant and a description of each flow stream (i.e. the weight distribution, percent ash, pyritic sulfur and total sulfur, moisture, BTU content, recoveries, and specific gravity of separation). COALPREP also includes a capability for calculating the cleaning cost per ton of coal. The IBM PC version contains two auxiliary programs, DATAPREP and FORLIST. DATAPREP is an interactive preprocessor for creating and editing COALPREP input data. FORLIST converts carriage-control characters in FORTRAN output data to ASCII line-feed (X''0A'') characters.« less

    Consol R D is conducting a three-year program to characterize process and product streams from direct coal liquefaction process development projects. The program objectives are two-fold: (1) to obtain and provide appropriate samples of coal liquids for the evaluation of analytical methodology, and (2) to support ongoing DOE-sponsored coal liquefaction process development efforts. The first objective will utilize analytical techniques which have not been fully demonstrated; the second objective involves more previously proven methods. This quarter, two feed coals and 39 process oils from Wilsonville Run 258 were analyzed to provide information on process performance. Run 258 was operated in the thermal/catalytic Close-Coupled Integrated Two-Stage Liquefaction (CC-ITSL) mode with ash recycle. The subbituminous feed coals were from the Spring Creek Mine (Anderson and Dietz seams) and from the Black Thunder Mine (Wyodak and Anderson seams). Shell 324 catalyst was used in the second stage. Various coal samples related to Wilsonville Run 259 were analyzed for chemical and petrographic composition. These results will be given in a future report, which covers all of Run 259. 18 figs., 24 tabs.

    The Clean Coal Act Amendments of 1990 identify a number of hazardous air pollutants as candidates for regulation. Should regulations be imposed on emission of these pollutants from coal-fired power plants, a sound understanding of the fundamental principles controlling their formation and partition will be needed. A new Toxics Partitioning Engineering Model (ToPEM) has been developed by a broad consortium to be useful to regulators and utility planners. During the last quarter coal analysis was completed on the final program coal, from the Wyodak Seam of the Powder River Basin, Combustion testing continued, including data collected on the self-sustained combustor. Efforts were directed to identify the governing mechanisms for trace element vaporization from the program coals. Mercury speciation and measurements were continued. Review of the existing trace element and organics emission literature was completed. And, model development was begun.

    Resinite is a naturally occurring substance found in coal and derived from original plant resins. It has been commercially exploited in the western USA for use in adhesives, varnishes and thermal setting inks. The overall objective of this project is to compare the properties of the resinite contained in Illinois Basin coals to resinite being commercially exploited in the western US, and to recover the resinite from Illinois coals by microbubble column floatation techniques. The significance of this study is that it has the potential to show the way to recover a valuable chemical, resinite, from coal using only physical processing techniques. The value of the resinite at $1.00/kg or $0.50/lb makes it about fifty times more valuable than steam coal. The removal of resinite from coal does not decrease the value of the remaining coal in any way. During this quarter pure concentrates of resinite from Herrin No. 6 Seam were produced by the density gradient centrifugation technique. This material is also now being characterized by petrographic and chemical methods. Another accomplishment this quarter was the completion of a series of microbubble column flotation tests under eight different conditions. The tests were successful in producing concentrates that are now being evaluated. The significance of the work done during this quarter is the confirmation that the resinite in an Illinois coal can be successfully separated in quantities useful for testing and analysis.

  1. USE OF COAL DRYING TO REDUCE WATER CONSUMED IN PULVERIZED COAL POWER PLANTS

    This is the seventh Quarterly Report for this project. The background and technical justification for the project are described, including potential benefits of reducing fuel moisture, prior to firing in a pulverized coal boiler. Coal drying experiments were performed with lignite and Powder River Basin coals to determine the effects of inlet air moisture level on the equilibrium relationship between coal moisture and exit air relative humidity and temperature. The results show that, for lignite, there is a slight dependence of equilibrium moisture on inlet humidity level. However, the equilibrium relationship for PRB coal appears to be independent of inlet air humidity level. The specific equilibrium model used for computing lignite coal dryer performance has a significant effect on the prediction accuracy for exit air relative humidity; but its effects on predicted coal product moisture, exit air temperature and specific humidity are minimal. Analyses were performed to determine the effect of lignite product moisture on unit performance for a high temperature drying system. With this process design, energy for drying is obtained from the hot flue gas entering the air preheater and the hot circulating cooling water leaving the steam condenser. Comparisons were made to the same boiler operating with lignite which had been dried off-site.

    The objective of this research is to develop a mechanistic understanding of the oxidation of coal and coal pyrite, and to correlate the intrinsic physical and chemical properties of these minerals, along with changes resulting from oxidation, with those surface properties that influence the behavior in physical cleaning processes. The results will provide fundamental insight into oxidation, in terms of the bulk and surface chemistry, the microstructure, and the semiconductor properties of the pyrite. During the eighth quarter, wet chemical and dry oxidation tests were done on Upper Freeport coal from the Troutville {number_sign}2 Mine, Clearfield County, Pennsylvania. In addition electrochemical experiments were done on electrodes prepared from Upper Freeport coal pyrite and Pittsburgh coal pyrite samples provided by the US Bureau of Mines, Pittsburgh Research Center, Pennsylvania.

    Progress continued at MHD coal-fired flow facility. UTSI reports on progress in developing the technology for the steam bottoming portion of the MHD Steam Combined Cycle Power Plant. No Proof-of-Concept (POC) testing was conducted during the quarter but data analyses are reported from the test conducted during the prior quarter. Major results include corrosion data from the first 500 hours of testing on candidate tube materials in the superheater test module (SHTM). Solids mass balance data, electrostatic precipitator (ESP) and baghouse (BH) performance data, diagnostic systems and environmental data results from previous POC tests are included. The major activities this quarter were in facility modifications required to complete the scheduled POC test program. Activities reported include the installation of an automatic ash/seed removal system on the SHTM, the BH, and ESP hoppers. Also, a higher pressure compressor (350 psi) is being installed to provide additional blowing pressure to remove solids deposits on the convective heat transfer tubes in the high temperature zone where the deposits are molten. These activities are scheduled to be completed and ready for the next test, which is scheduled for late May 1990. Also, experiments on drying western coal are reported. The recommended system for modifying the CFFF coal system to permit processing of western coal is described. Finally, a new effort to test portions of the TRW combustor during tests in the CFFF is described. The status of system analyses being conducted under subcontract by the Westinghouse Electric Corporation is also described. 2 refs., 18 figs., 3 tabs.

    The Energy Information Administration (EIA) prepares quarterly, short-term energy supply, demand, and price projections for publication in January, April, July, and October in the Outlook. The forecast period for this issue of the Outlook extends from the third quarter of 1996 through the fourth quarter of 1997. Values for the second quarter of 1996, however, are preliminary EIA estimates (for example, some monthly values for petroleum supply and disposition are derived in part from weekly data reported in the Weekly Petroleum Status Report) or are calculated from model simulations using the latest exogenous information available (for example, electricity sales and generation are simulated using actual weather data). The historical energy data, compiled in the third quarter 1996 version of the Short-Term Integrated Forecasting System (STIFS) database, are mostly EIA data regularly published in the Monthly energy Review, Petroleum Supply Monthly, and other EIA publications. Minor discrepancies between the data in these publications and the historical data in this Outlook are due to independent rounding. The STIFS database is archived quarterly and is available from the National Technical Information Service.

    2007-07-18

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

    Liang-Shih Fan; Fanxing Li

    2006-07-15

    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.

    1986-12-01

    X-ray Computed Tomography (CT) is a method of mapping with x-rays the internal structures of coal. The technique normally produces 2-D images of the internal structures of an object. These images can be recast to create pseudo 3-D representations. CT of coal has been explored for a variety of different applications to coal and coal processing technology. In a comparison of CT data with conventional coal analyses and petrography, CT was found to offer a good indication of the total ash content of the coal. The spatial distribution of the coal mineral matter as seen with CT has been suggested as an indicator of coal washability. Studies of gas flow through coal using xenon gas as a tracer have shown the extremely complicated nature of the modes of penetration of gas through coal, with significant differences in the rates at which the gas can pass along and across the bedding planes of coal. In a special furnace designed to allow CT images to be taken while the coal was being heated, the pyrolysis and gasification of coal have been studied. Gasification rates with steam and CO/sub 2/ for a range of coal ranks have been obtained, and the location of the gasification reactions within the piece of coal can be seen. Coal drying and the progress of the pyrolysis wave into coal have been examined when the coal was subjected to the kind of sudden temperature jump that it might experience in fixed bed gasifier applications. CT has also been used to examine stable flow structures within model fluidized beds and the accessibility of lump coal to microbial desulfurization. 53 refs., 242 figs., 26 tabs.

    1995-10-01

    The primary purpose of this report is to examine changes in domestic coal distribution and railroad coal transportation rates since enactment of the Clean Air Act Amendments of 1990 (CAAA90). From 1988 through 1993, the demand for low-sulfur coal increased, as a the 1995 deadline for compliance with Phase 1 of CAAA90 approached. The shift toward low-sulfur coal came sooner than had been generally expected because many electric utilities switched early from high-sulfur coal to ``compliance`` (very low-sulfur) coal. They did so to accumulate emissions allowances that could be used to meet the stricter Phase 2 requirements. Thus, the demand for compliance coal increased the most. The report describes coal distribution and sulfur content, railroad coal transportation and transportation rates, and electric utility contract coal transportation trends from 1979 to 1993 including national trends, regional comparisons, distribution patterns and regional profiles. 14 figs., 76 tabs.

    The Energy Information Administration (EIA) prepares quarterly short-term energy supply, demand, and price projections for printed publication in January, April, July, and October in the Short-Term Energy Outlook. The details of these projections, as well as monthly updates on or about the 6th of each interim month, are available on the internet at: www.eia.doe.gov/emeu/steo/pub/contents.html. The forecast period for this issue of the Outlook extends from the fourth quarter of 1997 through the fourth quarter of 1998. Values for the fourth quarter of 1997, however, are preliminary EIA estimates (for example, some monthly values for petroleum supply and disposition are derived in part from weekly data reported in EIA`s Weekly Petroleum Status Report) or are calculated from model simulations that use the latest exogenous information available (for example, electricity sales and generation are simulated by using actual weather data). The historical energy data, compiled in the fourth quarter 1997 version of the Short-Term Integrated Forecasting System (STIFS) database, are mostly EIA data regularly published in the Monthly Energy Review, Petroleum Supply Monthly, and other EIA publications. Minor discrepancies between the data in these publications and the historical data in this Outlook are due to independent rounding. The STIFS model is driven principally by three sets of assumptions or inputs: estimates of key macroeconomic variables, world oil price assumptions, and assumptions about the severity of weather. 19 tabs.

    1993-11-15

    The Strategic Petroleum Reserve serves as one of the most important investments in reducing the Nation`s vulnerability to oil supply disruptions. This Quarterly Report highlights activities undertaken during the third quarter of calendar year 1993, including: inventory of petroleum products stored in the Reserve, under contract and in transit at the end of the calendar quarter; fill rate for the quarter and projected fill rate for the next calendar quarter; average price of the petroleum products acquired during the calendar quarter; current and projected storage capacity and plans to accelerate the acquisition or construction of such capacity; analysis of existing or anticipated problems with the acquisition and storage of petroleum products and future expansion of storage capacity; funds obligated by the Secretary from the SPR Petroleum Account and the Strategic Petroleum Reserve Account during the prior calendar quarter and in total; and major environmental actions completed, in progress, or anticipated. Samples of the oil revealed two problems that, although readily correctable, have reduced the availability of some of the oil inventory for drawdown in the near-term. These problems are: (1) a higher-than-normal gas content in some of the crude oil, apparently from years of intrusion of methane form the surrounding salt formation; and (2) elevated temperatures of some of the crude oil, due to geothermal heating, that has increased the vapor pressure of the oil. Investigations are proceeding to determine the extent to which gas intrusion and geothermal heating are impacting the availability of oil for drawdown. Preliminary designs have been developed for systems to mitigate both problems.

    Understanding the surface properties of coal is important for predicting the physical-chemical behavior of coal during coal cleaning combustion and conversion. Data on surface properties help coal scientists and engineers in the design of effective coal desulfurization processes, and thereby aid in the marketability of Illinois Basin coals. The main objective of this project is to characterize the surface properties (surface area, porosity, pore size distribution, surface charge, and surface chemical structure) of eight coals in the Illinois Basin Coal Sample Program (IBCSP), and explore statistical relationships between surface properties and other coal characteristics.

    The purpose of this contract is to develop and refine the Integrated Environmental Control Model (IECM). In its current configuration, the IECM provides a capability to model various conventional and advanced processes for controlling air pollutant emissions from coal-fired power plants before, during, or after combustion. The principal purpose of the model is to calculate the performance, emissions, and cost of power plant configurations employing alternative environmental control methods. The model consists of various control technology modules, which may be integrated into a complete utility plant in any desired combination. In contrast to conventional deterministic models, the IECM offers the unique capability to assign probabilistic values to all model input parameters, and to obtain probabilistic outputs in the form of cumulative distribution functions indicating the likelihood of different costs and performance results. The work in this contract is divided into two phases. Phase I deals with further developing the existing version of the IECM and training PETC personnel on the effective use of the model. Phase H deals with creating new technology modules, linking the IECM with PETC databases, and training PETC personnel on the effective use of the updated model. The present report summarizes recent progress on the Phase I effort during the period April 1, 1995 through June 30, 1995. This report presents additional revisions to the new cost models of flue gas desulfurization (FGD) technology initially reported in our fourth quarterly report. For convenience, the complete description of the revised FGD models are presented here.

    This project proposes a new method for removing organic sulfur from Illinois coals using readily available farm products. It proposes to use air and vegetable oils to disrupt the coal matrix, oxidize sulfur forms, increase volatiles, and desulfurize coal. This will be accomplished by impregnating coals with polyunsaturated oils, converting the oils to their hydroperoxides, and heating. Since these oils are relatively inexpensive and easily applied, this project could lead to a cost effective method for removing organic sulfur from coals. Moreover, the oils are environmentally safe; they will produce no noxious products and will improve burning qualities of solid products. Preliminary experiments showed that IBC 104 coal catalyzes the formation of hydroperoxides in safflower oil and that more sulfur is extracted from the treated than untreated coal. During the first quarter the requirement of an added photosensitizer was eliminated, the catalytic effect of coal was confirmed, and the existence of a complex set of reactions was revealed. During the second quarter, working with IBC-108 coal (2.3% organic S, 0.4% pyrite S), the effects of different extraction solvents were examined. A new pretreatment which combines alkali with linseed oil was discovered. Best organic sulfur removal is approximately 26% using alkali pretreatment combined with linseed oil at 100[degrees]C. BTU loses can be kept to a minimum of 3% with proper use of solvents. During this third quarter the effects of different ratios of oil:coal, different temperatures, and different reaction times were completely examined. The effects of alkali on sulfur removal were further investigated. Best organic sulfur removal reaches 34% using ammonia pretreatment, then oil and finally aqNA2CO3 extraction.

    A new use for Illinois coal is as fuel injected into a blast furnace to produce molten iron as first step in steel production. Because of cost and decreasing availability, metallurgical coke is being replaced by coal injected at the tuyere area of the furnace where the blast air enters. Purpose of this study is to evaluate combustion of Illinois coal in the blast furnace injection process in a pilot plant test facility. (Limited research to date suggests that coals of low fluidity and moderate to high S and Cl contents are suitable for blast furnace injection.) This proposal is intended to complete the study under way with Armco and Inland and to demonstrate quantitatively the suitability of Herrin No. 6 and Springfield No. 5 coals for injection. Main feature of current work is testing of Illinois coals at CANMET`s pilot plant coal combustion facility. During this quarter, two additional 300-pound samples of coal (IBCSP-110 Springfield No. 5 and an Appalachian coal) were delivered. Six Illinois Basin coals were analyzed with the CANMET model and compared with other bituminous coals from the Appalachians, France, Poland, South Africa, and Colombia. Based on computer modeling, lower rank bituminous coals, including coal from the Illinois Basin, compare well in injection with a variety of other bituminous coals.

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

    Previous research has shown that addition of lignin and lignin-derived liquids to coal stirred in tetralin under mild reaction conditions (375{degrees}C and 300--500 psig) results in a marked enhancement in the rate of coal depolymerization. In this quarterly report, overall mass balances on experiments conducted with tetralin, coal, lignin and coal-lignin mixture are reported. Overall mass recoveries of 95--99% of the total mass charged to the reactor were obtained. A number of experiments were conducted on coal, lignin and coal-lignin depolymerization. A careful statistical analysis of the data shows that coal depolymerization is enhanced by 10.4%, due to the lignin addition. The liquids obtained are being examined for their elemental composition, and molecular weight determination by size exclusion chromatography. The stability of the liquid products is being examined in various environments. The gaseous product analyses show that the major gases produced during the course of depolymerization are CO, CH{sub 4}, and CO{sub 2}. When coal and lignin are reacted together, the amount of CO and CH{sub 4}produced respectively 12% and 38% greater than the corresponding amount of gases calculated, based on the weighted average of values obtained for coal and lignin alone. The data obtained show that lignin addition to coal is synergistic in that not only is the extent of coal depolymerization increased, but the gas produced contains higher concentrations of more desirable gaseous products.

  11. Strategic petroleum reserve. Quarterly report

    1995-08-15

    The Strategic Petroleum Reserve reduces the Nation`s vulnerability to oil supply disruptions. Its existence provides a formidable deterrent to the use of oil as a political instrument and an effective response mechanism should a disruption occur. The Strategic Petroleum Reserve was created pursuant to the Energy Policy and Conservation Act of December 22, 1975 (Public Law 94-163). Its purposes are to reduce the impact of disruptions in supplies of petroleum products and to carry out obligations of the United States under the Agreement on an International Energy Program. Section 165(a) of the Act requires the submission of Annual Reports and Section 165(b)(1) requires the submission of Quarterly Reports. This Quarterly Report highlights activities undertaken during the second quarter of calendar year 1995, including: inventory of petroleum products stored in the Reserve; current and projected storage capacity, analysis of existing or anticipated problems with the acquisition and storage of petroleum products, and future expansion of storage capacity; funds obligated by the Secretary from the SPR Petroleum Account and the Strategic Petroleum Reserve Account during the prior calendar quarter and in total; and major environmental actions completed, in progress, or anticipated.

    On September 30, 1993, the U.S. Department of Energy-Morgantown Energy Technology Center and Southern Illinois University at Carbondale (SIUC) entered into a cooperative research agreement entitled {open_quotes}Management of Dry Flue Gas Desulfurization By-Products in Underground Mines{close_quotes} (DE-FC21-93MC30252). Under the agreement Southern Illinois University at Carbondale will develop and demonstrate several technologies for the placement of coal combustion residues in abandoned coal mines, and will assess the environmental impact of such underground residues placement. Previous quarterly Technical Progress Reports have set forth the specific objectives of the program, and a discussion of these is not repeated here. Rather, this report discusses the technical progress made during the period April 1 - June 30, 1995. A final topical report on the SEEC, Inc. demonstration of its technology for the transporting of coal combustion residues was completed during the quarter, although final printing of the report was accomplished early in July, 1995. The SEEC technology involves the use of Collapsible Intermodal Containers (CIC`s) developed by SEEC, and the transportation of such containers - filled with fly ash or other coal combustion residues - on rail coal cars or other transportation means. Copies of the final topical report, entitled {open_quotes}The Development and Testing of Collapsible Intermodal Containers for the Handling and Transport of Coal Combustion Residues{close_quotes} were furnished to the Morgantown Energy Technology Center. The Rapid Aging Test colums were placed in operation during the quarter. This test is to determine the long-term reaction of both the pneumatic and hydraulic mixtures to brine as a leaching material, and simulates the conditions that will be encountered in the actual underground placement of the coal combustion residues mixtures. The tests will continue for about one year.

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

    Froth flotation technique is an effective and efficient process for recovering of ultra-fine (minus 74 mm) clean coal. Economical dewatering of an ultra-fine clean coal product to a 20% level moisture will be an important step in successful implementation of the advanced cleaning processes. This project is a step in the Department of Energy's program to show that ultra-clean coal could be effectively dewatered to 20% or lower moisture using either conventional or advanced dewatering techniques. The cost-sharing contract effort is for 45 months beginning September 30, 1994. This report discusses technical progress made during the quarter from January 1 ? March 31, 1998.

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

    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.
