Coal combustion science. Quarterly progress report, April 1993--June 1993  

Science Conference Proceedings (OSTI)

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

Volatiles trapped in coals: Second quarterly report  

SciTech Connect

We have been able to collect and characterize volatiles that are evolved in the grinding of coal. We have developed a very sensitive method for collecting volatiles evolved in grinding. A sealed, gas tight, grinding apparatus has been built. With this system we can collect volatiles freed from the coal matrix during grinding. To do this a 125 cm/sup 3/ sample of coal is placed in to a 1 liter sealable ball mill jar. The jar is evacuated and the coal ground for 1 hr. The jar is then removed from the ball mill and evacuated into our sample collection system. Gas from the jar is pumped through two stages of dust filtering into a liquid nitrogen cold trap charged with 5 ml of methylene chloride. After warming the trap is shaken so that any gas from the sample mixes with and dissolves in the methylene chloride. One microliter samples of the methylene chloride are injected into a Finnegan GCMS. Preliminary analysis of mass spectra from peaks in the RIC show the presence of hydrocarbons. It was possible to definitively identify cyclohexene. The total amount of hydrocarbons seen is low. The attached figure is the mass spectra of the cyclohexene that was collected from the ground coal. 1 fig.

Sixteenth Quarterly Report Regulation of Coal Polymer Degradation by Fungi  

SciTech Connect

Three phenomena which concern coal solubilization and depolymerization were studied during this reporting period. Previous investigations have shown that lignin peroxidases mediate the oxidation of soluble coal macromolecule. Because it appears to be a substrate, soluble coal macromolecule is also an inhibitor of veratryl alcohol oxidation, a reaction that is mediated by these enzymes. The mechanism of inhibition is complex in that oxidation (as assayed by decolorization) of soluble coal macromolecule requires the presence of veratryl alcohol and veratryl alcohol oxidation occurs only after a substantial lag period during which the soluble coal macromolecule is oxidized. In a previous quarterly report we proposed a reaction mechanism by which this may occur. During the present reporting period we showed that our proposed reaction mechanism is consistent with classical enzyme kinetic theory describing enzyme activity in the presence of a potent inhibitor (i.e., an inhibitor with a very low KI ). The oxidative decolorization and depolymerization of soluble coal macromolecule was also studied. Because wood rotting fungi produce hydrogen peroxide via a variety of reactions, we studied the effect of hydrogen peroxide on soluble coal macromolecule decolorization and depolymerization. Results showed that substantial decolorization occurred only at hydrogen peroxide concentrations that are clearly non-physiological (i.e., 50 mM or greater). It was noted, however, that when grown on solid lignocellulosic substrates, wood rotting fungi, overtime, cumulatively could produce amounts of hydrogen peroxide that might cause significant oxidative degradation of soluble coal macromolecule. Thirdly, we have shown that during oxalate mediated solubilization of low rank coal, a pH increase is observed. During this reporting period we have shown that the pH of solutions containing only sodium oxalate also undergo an increase in pH, but to a lesser extent than that observed in mixtures containing sodium oxalate and low rank coal. It is our hypothesis that bicarbonate ion is formed during oxalate mediated solubilization of low rank coal and this is responsible for the increase in pH that is observed. A general reaction by which this occurs is proposed herein.

Mild coal pretreatment to improve liquefaction reactivity. Quarterly technical progress report, June--August 1991  

SciTech Connect

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.

Oxidation of coal and coal pyrite mechanisms and influence on surface characteristics. [Quarterly] technical progress report, April--June 1993  

SciTech Connect

The objective of this research is to develop a mechanistic understanding of the oxidation of coal and coal pyrite, and to correlate the intrinsic physical and chemical properties of these minerals, along with changes resulting from oxidation, with those surface properties that influence the behavior in physical cleaning processes. The results will provide fundamental insight into oxidation, in terms of the bulk and surface chemistry, the microstructure, and the semiconductor properties of the pyrite. During the eleventh quarter, dry thermal oxidation tests were done on coal samples from the Pennsylvania State Coal Bank. As-received and oxidized coal samples were studied by ion-exchange methods to determine the carboxylate and phenolic group concentrations. Film flotation tests were done to characterize the flotability of as-received and oxidized coals. In addition, electrokinetic tests were done on different coals, to obtain information pertinent to the selection of flotation reagents. DRIFT analysis was done to characterize the structure of coals.

Coal liquefaction. Quarterly report, October-December 1978  

SciTech Connect

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 ERDA. The Bureau of Mines, US Department of the Interior, had started work in the 1930's. Current work is aimed at improved process configurations for both catalytic and noncatalytic 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. Each of these processes are described briefly.

Combustion characterization of beneficiated coal-based fuels. Quarterly report No. 12, January--March 1992  

Science Conference Proceedings (OSTI)

The Pittsburgh Energy Technology Center of the US Department of Energy has contracted with Combustion Engineering, Inc. (CE) to perform a five-year project on ``Combustion Characterization of Beneficiated Coal-Based Fuels.`` The beneficiated coals are produced by other contractors under the DOE Coal Preparation Program. Several contractor-developed advanced coal cleaning processes are run at pilot-scale cleaning facilities to produce 20-ton batches of fuels for shipment to CE`s laboratory in Windsor, Connecticut. CE then processes the products into either a coal-water fuel (CWF) or a dry microfine pulverized coa1 (DMPC) form for combustion testing. The objectives of this project include: (1) the development of an engineering data base which will provide detailed information on the properties of BCFs influencing combustion, ash deposition, ash erosion, particulate collection, and emissions; and (2) the application of this technical data base to predict the performance and economic impacts of firing the BCFs in various commercial boiler designs. The technical approach used to develop the technical data includes: bench-scale fuel property, combustion, and ash deposition tests; pilot-scale combustion and ash effects tests; and full-scale combustion tests. During the third quarter of 1992, the following technical progress was made: Continued analyses of drop tube furnace samples to determine devolatilization kinetics; completed editing of the fifth quarterly report and sent it to the publishing office; and prepared two technical papers for conferences.

Combustion of calcium-exchanged coal. First quarterly report  

SciTech Connect

The work performed during this first period includes equipment modification, development of analytical methods, oxidative pretreatment runs and combustion runs. The coal feeding section of an existing furnace was modified for uninterrupted feeding and better control of residence time. Analytical methods for sulfur and calcium in the coal and ash and for gaseous SO/sub 2/ were standardized. Oxidative pretreatment experiments were conducted in a fluidized bed at temperatures about 200/sup 0/C to evaluate the potential of this method for increasing the ion exchange capacity of coals and determine the accompanying loss of heating value. Combustion experiments were carried out at very high particle temperatures (2000/sup 0/K) at which a large fraction of the calcium additive was vaporized while 50 to 80% of the sulfur evolved as sulfur oxide. Continuing combustion experiments will be conducted at lower particle temperatures.

Highlights of the previous report were experiments on coal desulfurization to ascertain reproducibility of results obtained earlier. Activity since the last report was related to the room temperature desulfurization of dibenzothiophene. This startling result is probably the authors most important to date. Because this invention has not yet received a DOE docket number and the disclosure to the university is in progress, results will be related to DOE/PETC in due course. A patent disclosure on the invention is in progress, but more experiments are needed before a Continuation in Part to the pending patent is made. The university has elicited interest in their developing technology from three coal companies and a paper company. Negotiations aimed at establishing confidentiality agreements are underway.

The objectives of this project include: (1) the development of an engineering data base which will provide detailed information on the properties of beneficiated coal-based fuels (BCFs) influencing combustion, ash deposition, ash erosion, particulate collection, and emissions; and (2) the application of this technical data base to predict the performance and economic impacts of firing the BCFs in various commercial boiler designs. The technical approach used to develop the technical data includes: bench-scale fuel property, combustion, and ash deposition tests; pilot-scale combustion and ash effects tests; and full-scale combustion tests. Subcontractors perform parts of the test work are the Massachusetts Institute of Technology Physical Science, Inc. Technology Company and the University of North Dakota Energy and Environmental Research Center. Twenty fuels will be characterized during the three-year base program: three feed coals, fifteen BCFs, and two conventionally cleaned coals for full-scale tests. Approximately nine BCFs will be in dry ultra fine coal (DUC) form, and six BCFs will be in coal-water fuel (CWF) form. Additional BCFs would be characterized during optional project supplements. During the third quarter of 1991, the following technical progress was made: Continued analyses of drop tube furnace samples to determine devolatilization kinetics; completed analyses of the samples from the pilot-scale ash deposition tests of three Freeport Pittsburgh 8 fuels; conducted pilot-scale combustion and ash deposition tests of a fresh batch of Upper Freeport parent coal in the CE fireside Performance Test Facility; and completed editing of the fourth quarterly report and sent it to the publishing office.

Characterization and supply of coal-based fuels. Quarterly report, August 1, 1989--October 31, 1989  

SciTech Connect

Under the Department of Energy`s Combustor Technology Program, combustor contractors are developing combustor systems for use in residential, commercial, light industrial and industrial retrofit markets. Well-characterized coal based fuels possessing appropriate specifications are required by the contractors for their developmental test programs. Fuels may be dry pulverized or micronized coal or coal-water fuels. In support of these equipment development efforts, Energy International is providing such fuels. A complete list of all of the delivered fuels,the quantities and users are provided in the Appendix. Their fuel needs ranged from small sample quantities (e.g. 5 to 500 lbs.) up to 15 tons per delivery; by now most no longer need fuel. During the twelfth quarter of this contract (August 1, 1989 through October 31, 1989) the primary activities were involved with: (1) Continuation of the procurement, preparation and delivery of coal-based fuels for the combustor contractors. (2) Continuation of the interaction with combustor contractors in order to update their fuel specifications, fuel requirements and delivery schedules.

Combustion characterization of beneficiated coal-based fuels. Quarterly report No. 9, April--June 1991  

Science Conference Proceedings (OSTI)

The Pittsburgh Energy Technology Center of the US Department of Energy has contracted with Combustion Engineering, Inc. (CE) to perform a five-year project on ``Combustion Characterization of Beneficiated Coal-Based Fuels.`` The beneficiated coals are produced by other contractors under the DOE Coal Preparation Program. Several contractor-developed advanced coal cleaning processes are run at pilot-scale cleaning facilities to produce 20-ton batches of fuels for shipment to CE`s laboratory in Windsor, Connecticut. CE then processes the products into either a coal-water fuel (CWF) or a dry microfine pulverized coa1 (DMPC) form for combustion testing. The objectives of this project include: (1) the development of an engineering data base which will provide detailed information on the properties of BCFs influencing combustion, ash deposition, ash erosion, particulate collection, and emissions; and (2) the application of this technical data base to predict the performance and economic impacts of firing the BCFs in various commercial boiler designs. During the second quarter of 1991, the following technical progress was made: completed drop tube furnace devolatilization tests of the spherical oil agglomeration beneficiated products; continued analyses of samples to determine devolatilization kinetics; continued analyses of the data and samples from the CE pilot-scale tests of nine fuels; completed writing a summary topical report including all results to date on he nine fuels tested; and presented three technical papers on the project results at the 16th International Conference on Coal & Slurry Technologies.

The use of solid-state NMR techniques for the analysis of water in coal and the effect of different coal drying techniques on the structure and reactivity of coal. Quarterly report, June 1--August 31, 1993  

SciTech Connect

One area for improvement in the economics of coal liquefaction is coal drying, particularly for the lower rank coals. However, there is considerable evidence to show that drying has a detrimental effect on the liquefaction behavior of coals. Regarding the liquefaction of coal, there does not appear to have been any systematic study of the methods of coal drying on coal structure and the role water plays in enhancing or lessening coal reactivity toward liquefaction. To conduct this study two coals, the North Dakota Beulah Zap lignite and the Utah Blind Canyon coals were chosen. These coals represent a low and high rank coal, respectively. In addition, the Beulah Zap lignite has a high moisture content whereas the Blind Canyon coal (hvA) bituminous has a very low moisture content. The overall objectives of this study are to develop a nuclear magnetic resonance (NMR) method for measuring the water in coal, to measure the changes in coal structure that occur during coal drying, to determine what effect water has on retrograde/condensation reactions, and to determine the mechanism by which water may impact coal reactivity toward liquefaction. Different methods of drying are being investigated to determine if drying can be accomplished without destroying coal reactivity toward liquefaction. The objectives for this quarterly report period were (1) to measure the volumetric swelling ratio for initial and chemically-dried coals and (2) to conduct preliminary experiments concerning the exchange of water in coal with deuterium oxide (D{sub 2}O).

Oxidation of coal and coal pyrite mechanisms and influence on surface characteristics. Quarterly technical progress report, December 1, 1993--May 31, 1994  

SciTech Connect

The objective of this research is to develop a mechanistic understanding of the oxidation of coal and coal pyrite, and to correlate the intrinsic physical and chemical properties of these minerals, along with changes resulting from oxidation, with those surface properties that influence the behavior in physical cleaning processes. The results will provide fundamental insight into oxidation, in term of the bulk and surface chemistry, the microstructure, and the semiconductor properties of the pyrite. During the fourteenth and fifteenth quarters, flotation tests were done on Upper Freeport coal from the Troutville No. 2 Mine, Clearfield County, Pennsylvania and on coal samples from the Pennsylvania State Coal Bank. The influence of electrode potential on the surface properties of coal pyrite was tested using contact angle measurements on polarized Pittsburgh coal pyrite electrode.

Advanced direct coal liquefaction concepts. Quarterly report, October 1, 1993--December 31, 1993  

DOE Green Energy (OSTI)

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.

Co-firing high sulfur coal with refuse derived fuels. Quarterly report, October - December 1996  

DOE Green Energy (OSTI)

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.

Synthesis of methyl methacrylate from coal-derived syngas: Quarterly report,, October 1-December 31, 1997  

SciTech Connect

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.

Hindered diffusion of coal liquids. Quarterly report No. 10, December 18, 1994--March 17, 1995  

Science Conference Proceedings (OSTI)

The design of industrial catalysts requires that the diffusivity of the reacting species within the catalyst be accurately known. Nowhere is this more important than in the area of coal liquefaction and upgrading of coal liquids. In this area one is faced with the task of processing a number of heavy oils, containing metals and other contaminants, in a variety of process dependent solvents. It is important, therefore, on the basis of predicting catalyst activity, selectivity, and optimizing reactor performance, that the diffusivities of these oil species be accurately known. Throughout the experimental runs we will utilize a high pressure, high temperature diffusion of cell system. This diffusion system has been tested through the measurement of the diffusivity of a number of model coal liquids. The following were accomplished this quarter: During this quarter, we have initiated a series of transport investigations under high temperature (360{degrees}) high pressure (500 psi, H{sub 2}) reactive conditions. We have also continued our studies of formation and precipitation of fractal molecular aggregates in porous media. Small-angle scattering as well as precipitation data are analyzed to delineate the structure of the molecular colloidal aggregates that are formed, when a fluid is injected into the pore space of a porous medium to react with, or displace the in-place fluid. The results suggest that these colloidal structures are diffusion-limited particle and cluster aggregates. This is the first conclusive evidence for fractality of such molecular aggregates, which has important implications for their stability and molecular weight distribution, as well as modelling their flow and precipitation in a porous medium.

Bechtel, with South west research Institute, Amoco Oil R&D, and the M. W. Kellogg Co. as subcontractors, initiated a study on November 1, 1993, for the US Department of Energy`s Pittsburgh Energy Technology Center 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. 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. 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 Process Industry Modeling System software. The objective 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 effort conducted during the fourth quarter of 1995 were in the areas of: IL catalytic cracking--microactivity tests were conducted on various wax blends; IL wax hydrocracking--a pilot plant run was conducted on a wax/petroleum blend; and DL2 characterization and fractionation.

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.

After the remaining runs of the slurry preheater survey test program were completed January 14, the Fort Lewis Pilot Plant was shut down to inspect Slurry Preheater B and to insulate the coil for future testing at higher rates of heat flux. Radiographic inspection of the coil showed that the welds at the pressure taps and the immersion thermowells did not meet design specifications. Slurry Preheater A was used during the first 12 days of February while weld repairs and modifications to Slurry Preheater B were completed. Two attempts to complete a material balance run on Powhatan No. 6 Mine coal were attempted but neither was successful. Slurry Preheater B was in service the remainder of the quarter. The start of a series of runs at higher heat flux was delayed because of plugging in both the slurry and the hydrogen flow metering systems. Three baseline runs and three slurry runs of the high heat flux program were completed before the plant was shut down March 12 for repair of the Inert Gas Unit. Attempts to complete a fourth slurry run at high heat flux were unsuccessful because of problems with the coal feed handling and the vortex mix systems. Process Development Unit (P-99) completed three of the four runs designed to study the effect of dissolver L/D ratio. The fourth was under way at the end of the period. SRC yield correlations have been developed that include coal properties as independent variables. A preliminary ranking of coals according to their reactivity in PDU P-99 has been made. Techniques for studying coking phenomenona are now in place.

Coal air turbine ``CAT`` program, invention 604. Fifth quarter project report, October--December 1995  

SciTech Connect

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.

Solvent Refined Coal (SRC) process. Quarterly technical progress report, April 1979-June 1979  

DOE Green Energy (OSTI)

This report summarizes the progress of the Solvent Refined Coal (SRC) Project for the period March 25, 1979, through June 24, 1979. 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.

Nitration of polynuclear aromatic hydrocarbons in coal combustors and exhaust streams. Quarterly report, July 1, 1992--September 30, 1992  

SciTech Connect

Our efforts quarter were directed at preparing PAH samples at well-controlled extents of secondary pyrolysis. The same operating conditions used in the past were implemented this quarter to prepare PAH samples at well-controlled extents of secondary pyrolysis from a Pit. {number_sign}8 hvA bituminous coal. The new data are in excellent agreement with the old. Both ultimate yield values and soot percentages at particular furnace temperatures from these data sets am within experimental uncertainties. PAH samples have now been prepared to cover extents of conversion of coal tar into soot from 35--80 %. Additional runs during primary devolatilization have yielded PAH samples that cover nearly the full range of this process as well. Hence, all PAH samples from the Pit. {number_sign}8 coal sample are in hand. We also began to collect the analogous PAH samples from a subituminous coal. Efforts at sample analysis focused on testing and modification of the gravity-flow column chromatography procedure using actual tar samples. Extra samples collected during combustion experiments using the Pit. {number_sign}8 bituminous coal were used to refine the preparation technique. Solvent volumes were adjusted to optimize sample separation, and additional tests were conducted to determine the reproducibility of the fractionation and recovery. Further refinement in the experimental methodology allowed 80% recovery of the coal tar samples to be reproducibly achieved.

Coal combustion under conditions of blast furnace injection. [Quarterly] technical report, 1 December 1993--28 February 1994  

SciTech Connect

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.

Coal liquefaction process streams characterization and evaluation. Quarterly technical progress report, April 1--June 30, 1992  

Science Conference Proceedings (OSTI)

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.

Refining and end use study of coal liquids. Quarterly report, January--March 1996  

Science Conference Proceedings (OSTI)

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 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. 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 first quarter of 1996 were in the areas of: DL2 light distillate hydrotreating; and DL2 heave distillate catalytic cracking.

Rheological properties essential for the atomization of coal water slurries (CWS). Quarterly progress report, December 15, 1993--March 15, 1994  

SciTech Connect

During the past quarter, further rheological testing of the CWS were performed. The testing included low and high shear measurements. Oscillatory measurements were also planned, but the Haake CV20 accessory needed for this measurement has not yet been delivered. The CWS tested were PSOC-1527 from Middle Kittaning, PSOC-1472 from Lower Banner and PSOC 1475 (Elkhorn No. 3). The test results indicate that PSOC-1527 coal slurried much better than the PSOC 1472 coal. The rheological data is shown in Table 1.

Combustion of Illinois coals and chars with natural gas. [Quarterly] technical report, March 1, 1992--May 31, 1992  

Science Conference Proceedings (OSTI)

Combined combustion of coal and natural gas offers advantages compared to burning coal or natural gas alone. For example, low volatile coals or low volatile chars derived from treatment or gasification processes can be of limited use due to their poor flammability characteristics. However, the use of natural gas in conjunction with the solid fuel can provide the necessary ``volatiles`` to enhance the combustion. Additionally, natural gas provides a clean cofiring fuel source which can enhance the usefulness of coals with high sulfur content. Addition of natural gas may reduce SO{sub x} emissions through increased sulfur retention in the ash and reduce NO{sub x} emissions by varying local stoichiometry and temperature levels. This research program seeks to clarify the contributions and to identify the controlling mechanisms of coining natural gas with Illinois coal through studies of particle ignition, burning rates and ash characterization. The first two quarters focused on the ignition delay measurements and their analysis, along with the incorporation of particle porosity into the burning rate model. The emphasis of the third quarter was on a more detailed understanding of the burning rate process, as well as understanding of cofiring`s effects on sulfur retention. The contributions of particle burning area to the quantification of the particle burning mechanisms have been shown to be important and continue to be investigated. Ash samples for various methane concentrations under similar other conditions have shown positive trends in reducing S0{sub 2} emission through increased sulfur capture in the ash.

The use of solid-state NMR techniques for the analysis of water in coal and the effect of different coal drying techniques on the structure and reactivity of coal; Quarterly report, September 1--November 30, 1993  

SciTech Connect

For the research program reported here, different methods of drying are being investigated to determine if drying can be accomplished without destroying coal reactivity toward liquefaction. In an effort to understand the mechanism of water for enhancing coal liquefaction yield, the reactions of D{sub 2}O with the molecular constituents of coal during coal liquefaction are being investigated. This study involves the use of solution-state deuterium NMR, as well as, conventional solution-state {sup 1}H and {sup 13}C NMR analyses of the coal, and the coal liquids and residue from a coal liquefaction process. These D{sub 2}O transfer reactions will be conducted on coals which have been dried by various methods and rehydrated using D{sub 2}O and by successive exchange of H{sub 2}O associated with the coals with D{sub 2}O. The drying methods include thermal, microwave, and chemical dehydration of the coal. The overall objectives of this study are to develop a nuclear magnetic resonance (NMR) method for measuring the water in coal, to measure the changes in coal structure that occur during coal drying, to determine what effect water has on retrograde/condensation reactions, to determine the mechanism by which water may impact coal reactivity toward liquefaction, and to conduct D{sub 2}O exchange studies to ascertain the role of water in coal liquefaction. The objectives for this quarterly report period were (1) to measure the volumetric swelling ratio for thermally- and microwave-dried coals and (2) to conduct preliminary experiments concerning the exchange of water in coal with deuterium oxide (D{sub 2}O).

Preconversion processing of bituminous coals: New directions to improved direct catalytic coal liquefaction. Quarterly report, April 1, 1993--June 30, 1993  

DOE Green Energy (OSTI)

This project is focussed on the effective preconversion and liquefaction of coal. One of the main goals of this project was to reduce hydrogen consumption by decreasing the gas yield and increasing the oil yield based on a new structural model of coal. Two factors were critically evaluated during these tasks: (1) maximizing dissolution of associated coal and (2) different reactivity of fractions with different molecular weight. High-temperature soaking at{approximately} 350{degree}C in a coal liquid (recycle oil) was one method for effective dissolution not requiring additional chemicals and/or hydrogen. Two-step soaking at 350{degree}C and 400{degree}C was more effective for maximum dissolution. The addition of a relatively small amount of hydrogen peroxide during soaking slightly enhanced preconversion. Separation of dissolved coal into light and heavy fractions, followed by liquefaction of the heavy fraction, was effective as a means to improve product selectivity. Vacuum distillation was projected for the simple separation method. Cyclohexane extraction was used instead of vacuum distillation since cyclohexane solubles closely resemble the distillable oil fraction. Tests of the suggested procedure inferred a 30% increase in the oil yield and a 15--20% decrease in the gas yield. The effectiveness of the suggested procedure was confirmed from coal/oil ratios (g/ml) of 1/10--{1/2}. Batchwise vacuum distillation was tested, but was not successful due to an inherent problem in resolubilizing pitch samples in coal liquid. Progress this quarter is described.

Coal log pipeline research at University of Missouri. Second quarterly technical progress report, 1 April--30 June 1996  

SciTech Connect

During this quarter, significant progress has been made in the following, fronts of coal log pipeline research, development and technology transfer: 1. Design of the special 300-ton coal log compaction machine was completed, Furthermore, much progress has been made in the design of the system needed to feed coal into the coal log compaction machine, and the design of the system to remove logs automatically as soon as they are compacted. 2. Coal mixtures containing different amounts of moisture were compacted into 1.91- inch-diameter coal logs rapidly (in 6 seconds). It was found that for the Mettiki coal tested, the optimum moisture is around 8%. Under the test conditions (room temperature and 3% binders), the rapidly compacted coal logs with 8% moisture had less than 4% weight loss in 350 cycles of circulation. 3. Completed evaluation of the effectiveness of using wall lubricants to enhance coal log quality. Both calcium sterarate and MoS{sub 2} were found to be effective. 4. It was found that when the interior of a mold is not cleaned after coal log has been compacted, the coal mixture film clinging to the wall hardens in time and form a hard crust which affects the quality of the next log to be produced. But, if the second log is produced immediately after the first, no hard crust is formed and the quality of the second log, is not affected. 5. Coal logs made with the coal crushed by the Gundlach Company were found to be better than coal logs made with the coal crushed by the CPRC`s hammer mill. 7. A 320-ft-long, 6-inch-diameter coal log pipeline test facility was constructed in Rolla during this period. 8. Completed the simulation of an 8-inch-diameter, 20-mile-long coal log pipeline recirculating loop driven by a pump bypass. 9. Continued improvement was accomplished in the hydraulic model of HCP and CLP to predict pressure drop and capsule velocity for both single capsules and capsule train. Also, work has started to extend the analysis to sloped pipelines.

Hot coal gas desulfurization with manganese-based sorbents. Quarterly report, October--December 1993  

SciTech Connect

The focus of work being performed on Hot Coal Gas Desulfurization at the Morgantown Energy Technology Center is primarily in the use of zinc ferrite and zinc titanate sorbents; however, prior studies indicated that an alternate sorbent, manganese dioxide-containing ore in mixture with alumina (75 wt% ore + 25 wt% Al{sub 2}O{sub 3}) may be a viable alternative to zinc-based sorbents. Manganese, for example, has a lower vapor pressure in the elemental state than zinc hence it is not as likely to undergo depletion from the sorbent surface upon loading and regeneration cycles. Also manganese oxide is less readily reduced to the elemental state than iron hence the range of reduction potentials for oxygen is somewhat greater than for zinc ferrite. In addition, thermodynamic analysis of the manganese-oxygen-sulfur system shows it to be less amenable to sulfation than zinc ferrite. Potential also exists for utilization of manganese at higher temperatures than zinc ferrite or zinc titanate. This Fifth Quarterly Report documents progress in pellet testing via thermogravimetric analysis of pellet formulation FORM4-A of a manganese ore/alumina combination. This formulation, described more fully in the Quarterly Technical Progress Report of October 15, 1993, consists of manganese carbonate combined with alundum. A 2-inch fixed-bed reactor has been fabricated and is now ready for subjecting pellets to cyclic loading and regeneration; however, a minor problem has arisen during the regeneration cycle in that sulfur tends to form and plug the exit tube during the early stage of regeneration. This problem is about to be overcome by increasing the flow rate of air during the regeneration cycle resulting in more oxidizing conditions and hence less tendency for sulfide sulfur (S{sup =}) to oxidize to the intermediate elemental form (S{sup o}) rather than to 4-valent (S{sup +4}).

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.

Materials technology for coal-conversion processes. Eleventh quarterly report, April--June 1977  

DOE Green Energy (OSTI)

Silicon-carbide refractories with various bond systems exposed to molten slag at 1500/sup 0/C for 500 h in Run 4 showed virtually no attack. The resistance of the silicon carbide to slag attack is attributed to large thermal fluxes induced by water-cooled chills applied to the cold faces. Magnesia-chromia refractories exposed to molten slag at 1500/sup 0/C for 500 h in Run 5 were somewhat less resistant to slag attack than the silicon-carbide refractories. In-situ erosive-wear measurements on the Bi-Gas A106B low-carbon steel main coal feed line were obtained during the present quarter, with initial indications of a nominal 5% wall-thickness reduction after approximately 200 h of exposure. Acoustic leak-detection tests were carried out at the Morgantown Energy Research Center Valve Test Facility. Uniaxial tensile data were generated on several specified alloys in an as-received condition at temperatures of 750, 871, and 982/sup 0/C. A generalized approach, based on thermodynamic equilibria of gas mixtures, has been developed to evaluate the chemical potentials of the reactive elements, i.e., O, S, C, H, and N in multicomponent gas streams. The results showed that the chemical potentials can be uniquely established by the total atomic ratios C/H, C/O, and C/S in the initial gas mixture. A work plan for the experimental phase of the erosion program will include initial short-term testing to characterize the erosive behavior of various candidate materials for coal-conversion plants and also longer-term tests to characterize combined erosion/corrosion. Failed components from the Synthane Plant (ballooned pipe, pump impeller shaft (GA-207), thermowell, purge piping (BB-1), and the Battelle Char-Burner (Thermowells) were examined. (LTN)

Integrated low emissions cleanup system for direct coal fueled turbines. Twenty-eighth quarterly report, July--September 1994  

SciTech Connect

The United States Department of Energy, Morgantown Energy Research Center (DOE/METC), is sponsoring the development of advanced, coal-fueled turbine power plants such as pressurized fluid bed combustion and coal gasification combined cycles. A major technical challenge remaining for the development of the coal-fueled turbine is high-temperature 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 Integrated Low Emissions Cleanup (ILEC) concepts that have been configured to meet this technical challenge. These ILEC concepts simultaneously control sulfur, particulate, and alkali contaminants in the high-pressure process gases. This document reports the status of a program in the twenty-seventh quarter to develop this ILEC technology.

SciTech Connect

In Task 1 of this project, the use of a slurry reactor for indirect coal liquefaction is being studied. Work is being done using three indirect liquefaction routes involving synthesis gas - the Fisher-Tropsch reaction, the one-step conversion to methanol, and the two-step conversion to methanol via methyl formate. Experimental work and data analysis for the two-step methanol synthesis in a single slurry reactor were continued during the quarter. Experimental work included the effect of the H/sub 2//CO ratio on the simultaneous reactions and measurements of the solubility of hydrogen and CO in methanol and methyl formate. Reaction rates obtained experimentally for the simultaneous system were compared with rates calculated from the individual reactions. The two-step methanol synthesis involves two reactions, and one of the reactants in each reaction is a gas. The carbonylation of methanol requires CO and the hydrogenolysis of methyl formate requires H/sub 2/. The ratio of H/sub 2/ to CO is therefore a very important operating parameter, affecting the relative rates of the two reactions and the total methanol production rate. It may also affect the selectivity of the two reations. Two runs were made, one at a temperature of 121/sup 0/C and the other at 140/sup 0/C. All reaction conditions were constant except for the H/sub 2//CO ratio. The experimental procedure was the same as described previously. 61 refs.

Hydrocarbon-oil encapsulate bubble flotation of fine coal. Technical progress report for the twelfth quarter, July 1--September 30, 1993  

Science Conference Proceedings (OSTI)

Two modes of collector addition techniques including gasified collector transported in gas phase and direct collector addition techniques were applied in the column flotation to demonstrate the selectivity of utilizing the hydrocarbon-oil encapsulated air bubbles in the fine coal flotation process. A 3-in. flotation column was used to evaluate two modes of collector dispersion and addition techniques on the recovery and grade of fine coals using various ranks of coal. Five different coal samples were used in the column flotation test program. They are Mammoth, Lower Kittanning, Upper Freeport, Pittsburgh No. 8, and Illinois No. 6 seam coals, which correspond to anthracite-, low volatile-, medium volatile-, and high volatile-seam coals, respectively. In this quarterly report, the test results for the Upper Freeport seam coal and Pittsburgh No. 8 seam coal are reported.

Use of solid-state NMR techniques for the analysis of water in coal and the effect of different coal drying techniques on the structure and reactivity of coal. Quarterly report, September 1--November 30, 1991  

SciTech Connect

The overall objectives of this study are to develop an NMR method for measuring the water in coal, to measure the changes in coal structure that occur during coal drying, to determine what effect water has on retrograde/condensation reaction, and to determine the mechanism by which water any enhance coal reactivity toward liquefaction. Different methods of drying will be investigated to determine if drying can be accomplished without destroying coal reactivity toward liquefaction, thereby making coal drying an attractive and economical method for coal pretreatment. Coal drying methods will include thermal drying under different atmosphere and temperatures, drying with microwave radiation, and low-temperature chemical dehydration. The objectives for this quarterly report period were (1) to hire a student to help on the program, (2) to define the coals to be investigated and acquire the samples, (3) to order the necessary reagents and supplies, and (4) to conduct preliminary experiments for determining quantitatively using 2,2{prime}-dimethoxypropane and {sup 1}H NMR.

Engineering development of advanced physical fine coal cleaning for premium fuel applications. Quarterly technical progress report No. 4  

SciTech Connect

This project is a major step in the Department of Energy`s program to show that ultra-clean coal-water slurry fuel (CWF) can be produced from selected coals and that this premium fuel will be a cost-effective replacement for oil and natural gas now fueling some of the industrial and utility boilers in the United States. The replacement of oil and gas with CWF can only be realized if retrofit costs are kept to a minimum and retrofit boiler emissions meet national goals for clean air. These concerns establish the specifications for maximum ash and sulfur levels and combustion properties of the CWF. This cost-share contract is a 48-month program which started on September 30, 1992. This report discusses the technical progress made during the 4th quarter of the project from July 1 to September 30, 1993.

Rhelogical properties essential for the atomization of coal water slurries (CWS). Quarterly progress report, June 15, 1992--September 15, 1992  

SciTech Connect

The overall objective of this project is to perform experiments to understand the effect of high shear and extensional properties on the atomization of coal-water slurries (CWS). In the atomization studies, the mean drop size of the CWS sprays will be determined at various air-to CWS. A correlation between the extensional and high shear properties, particle size distributions and the atomization will be made in order to determine the influence of these parameters on the atomization of CWS. During the past quarter, several experimental studies on pressure dependent atomization of Coal-water slurries and simulated fluids were performed. Also surface tension, elastic, high and low shear viscosities were performed. These tests were performed to initiate the understanding of the fundamental parameters that govern the atomization process of CWS.

Multi-parameter on-line coal bulk analysis. First quarterly report, 1997  

SciTech Connect

The PFTNA experimental arrangement effectively utilizes in its measurements a given volume of coal, irrespective of the amount of coal contained in it. Coal shipped from the mines to coal preparation plants and coal-fired power plants, varies in size between 7.5 cm and dust. Thus, the measured volume can contain different amounts of coal depending on the size and the gravity settling of the measured coal sample. To compensate for changes in coal density within the measured coal volume, a gamma ray based densitometer was designed, utilizing the transmission through coal of a 662 keV {sup 137}Cs gamma ray. A narrowly collimated {sup 137}Cs source is placed on the one side of the coal sample, and the transmitted gamma rays are detected with a collimated 5.1cm x5.1cm NaI(TI) detector. For the 662 keV gamma ray, the absorption takes place primarily through the Compton effect, which has a Z/A dependence. Since for most of the elements contained in coal the Z/A ratio is nearly the same (except for H), the effective Z/A ratio in coal is constant, irrespective of changes that can occur in the elemental composition of coal. This premise was tested for various coal samples, whose elemental composition was established through independent ASTM-based analyses. Using several of the coal samples, a densitometer calibration was established. The sample density was varied by using crushed coal, compacted by various amounts.

Investigation of coal structure. Quarterly report, July 1, 1993--September 30, 1993  

SciTech Connect

The objective of this project is to investigate the physical structure of coal: the extent to which coal molecules may be covalently cross-linked and/or physically associated. Coal structure should be well understood for its effective utilization, and better understanding of physical structure of coal is the first step for the development of coal utilization. Solvent swelling of coal and multistep sequences of extraction are the two main probes of investigation. No single solvent appears to disrupt all of the relatively strong secondary interactions in coal. Various relatively strong secondary interactions need to be solvated step by step by appropriate procedures. If physical association is considerable, it should be possible to extract coal by the multistep sequences. Secondly, physical association will be evaluated by coal swelling. For the investigation of the effects of low coal concentration and continuous mixing, a new method will be developed. The focus of the work will be on a specific bituminous coal low in sulfur and iron. As requested by DOE, Blind Canyon coal (DECS-16) obtained from the Penn State Coal Bank has been used in this project.

Experiments on equilibrium adsorption loadings of various additives on 60 - 200 mesh Illinois 16 coal (DECS-2; Randolph county) were performed. The additives include n-propanol, n-butanol, 2-butanol, phenol, 2-naphthol, o-cresol and cyclohexanol. Equilibrium adsorption loadings of normal alcohols on 60 - 200 mesh Illinois No. 6 coal increase with increased numbers of carbons in their molecular formulas. Normal alcohols are more adsorbed on the coal than their branched alcohols. Adsorption loadings of single-ring compound phenol on the coal is higher than that of cyclohexanol. Adsorption loadings of double-ring compound 2-naphthol on the coal is much higher than that of single-ring compound phenol. The main objectives of this proposed research are to refine further the inverse liquid chromatography technique for the study of surface properties of raw coals, treated coals and coal minerals in water, to evaluate relatively surface properties of raw coals, treated coals and coal minerals by inverse liquid chromatography, and to evaluate floatability of various treated coals in conjunction with surface properties of coals.

The coals were treated with 20-ppM alcohol aqueous solutions (soln) for 1-24 hours at the 0.002-g/min mass flow rate at 225C. Flotation of Illinois No. 6 coal, treated with 1-propanol aqueous solution, increases with treatment durations for the first 10 hours and then decreases. Flotation of Illinois No. 6 coal, treated with isopropanol soln increases with treatment durations for the first 18 hours and then levels off. Flotation of Illinois No. 6 coal, treated with butanol soln, increases with treatment durations. Flotation of 1-butanol-treated Illinois No. 6 coal is higher than that of t-butanol-treated Illinois No. 6 coal. Flotation of Illinois No. 6 coal, treated with 20-ppM-isobutanol 20-ppM-HCl soln, increases with treatment durations for the first 10 hours treatment period, and then decreases sharply with treatment durations. Flotation of Wyodak coal, treated with water only, increases with treatment durations. Effects of water treatment on flotation of Wyodak coal are significantly pronounced compared to Illinois No. 6 coal.

Surface modified coals for enhanced catalyst dispersion and liquefaction. Quarterly report, 1996  

SciTech Connect

The aim of this work is to enhance catalyst loading and dispersion in coal for improved liquefaction by preadsorption of surfactants onto coal. The application of surfactants to coal beneficiation and coal-water slurry preparation is well known. However, the effects of surfactants on catalyst loading and dispersion prior to coal conversion processes have not been investigated. The current work is focused on the influence of the cationic surfactant dodecyl dimethyl ethyl ammonium bromide (DDAB) and sodium dodecyl sulfate (SDS, anionic) on the surface properties of a bituminous coal and its molybdenum and iron uptake from solution. In the previous report, it was shown that molybdenum loading onto the coal was enhanced by preadsorption of DDAB. The optimum concentration of this surfactant for effective adsorption of molybdenum at the natural pH of the coal slurry has been determined to be in the 0.1 to 0.25 M range. Preadsorption of SDS onto the coal was found to increase the uptake of iron by the coal; iron loading increased with increase in the concentration of the catalyst precursor. This observation is attributed to the increase in the negative surface charge properties of the coal with increase in the concentration of the surfactant. The results of the study show that DDAB enhances the adsorption of molybdenum whereas SDS is more effective for iron loading onto Illinois No. 6 (DECS-24) coal.

Biochemical removal of HAP precursors from coal. Quarterly technical progress report, 1996  

SciTech Connect

Shake flask tests were completed of microbial pyrite and HAP precursor removal from Rosebud subbituminous coal. Significant amounts of Ni, F, Mn, Cd, Co and Be were removed from this coal. Analyses in connection with leach column tests of Pittsburgh coal were completed and confirmed significant removal of Ni, F, Mn, Cd, Co and As from this coal. Although Hg was not removed from Pittsburgh coal by microbial attack, there was a correlation between HCl leaching of Hg from this coal and the extent of depyritization. Since HgS is soluble in HCl, the results suggest HgS is exposed by chemical and microbial dissolution of coal pyrite. Column tests with cleaned Indiana No. 5 coal are in progress and show significant early dissolution of Ni, Mn, Cd, Co and As. A final shake flask test with Kentucky No. 9 coal was begun. Pittsburgh coal with a low content of fines was shipped to the Idaho National Engineering Laboratory (INEL) in preparation for slurry column tests of HAP precursor removal. Project results were presented at the PETC contractor`s conference held in Pittsburgh. A project progress review meeting was also held with the PETC technical project monitor.

The interest group got under way effective January 1, 1994, with nine utility members, EPRI, Bechtel, and the Illinois Clean Coal Institute. DOE participation was effective October 1, 1994. The first meeting was held on April 22, 1994 in Springfield, Illinois and the second meeting was held on August 10--11, 1994 at Johnstown, Pennsylvania. Technical reviews were prepared in several areas, including the following: status of low rank coal upgrading, advanced physical coal cleaning, organic sulfur removal from coal, handling of fine coal, combustion of coal water slurries. It was concluded that, for bituminous coals, processing of fines from coal cleaning plants or impoundments was going to be less costly than processing of coal, since the fines were intrinsically worth less and advanced upgrading technologies require fine coal. Penelec reported on benefits of NOX reductions when burning slurry fuels. Project work was authorized in the following areas: Availability of fines (CQ, Inc.), Engineering evaluations (Bechtel), and Evaluation of slurry formulation and combustion demonstrations (EER/MATS). The first project was completed.

Coal combustion under conditions of blast furnace injection; [Quarterly] technical report, September 1--November 30, 1993  

SciTech Connect

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.

Refining and upgrading of synfuels from coal and oil shales by advanced catalytic processes. Quarterly report, July--September 1976  

DOE Green Energy (OSTI)

The objective of this program is to determine the feasibility and estimate the economics of hydroprocessing four synthetic fuels to distillate fuels, including high octane gasoline, using presently available technology. The feedstocks include three coal-derived synthetic crudes and shale oil. The first feedstock is Paraho crude shale oil, produced in the indirect-heated mode. The feed was received less than three weeks before the end of the quarter. The work to date consists of analyses of the shale oil. Results are incomplete. However, there is no reason to believe that this shale oil is atypical of Paraho shale oil prepared by the indirect-heated mode of retorting. Currently available technology is being studied to determine the appropriate methods for removal of fines and water to prepare the whole shale oil feed for hydrofining.

Intermediates formed during supercritical desulfurization of coal: Sixteenth quarterly technical progress report, April 1, 1987 to June 30, 1987  

Science Conference Proceedings (OSTI)

Last month, data was presented on a series of eight runs performed in the two liter reactor system under different reaction conditions, utilizing an Illinois No. 6 coal. The coal and solvent charges were held constant at 200 g each for all runs, and reaction time was one hour at a reaction temperature of 350/sup 0/C. Four of the runs utilized coal that had been treated with nitric acid solution, employing the ASTM procedure for sulfur forms analysis to remove the pyritic sulfur prior to reaction with alcohol. Both methanol and ethanol were utilized, and the effect of potassium hydroxide addition in an amount equal to 5% of the coal charged was also evaluated. Table 2 from last quarter's report is included here as Table 1 for convenient reference; it summarizes the processing conditions employed, desulfurization attained, and material balance information for the series of eight runs. The main objective of this series of runs was to permit a comparison to be made of the fluid phase composition between the various treatments employed; maximum desulfurization was not possible due to the current lower pressure limitation of the two liter reactor. Chromatographic analyses of the sulfur compounds present in the fluid phase samples taken during the course of the reactions are presented in Figures 1 through 8. All samples were collected at temperatures above supercritical. Vertical lines indicate the time during which the reaction temperature of 350/sup 0/C was maintained. The left vertical line denotes the end of the preheating time period, whereas the right one indicates the last data point completed before the final venting was performed. Relatively little fluid was removed from the reactor by sampling during the main reaction period. 8 figs., 1 tab.

Flash hydropyrolysis of coal. Quarterly report No. 4, October 1--December 31, 1977  

SciTech Connect

The principal objective of this program is to experimentally study the process variables and chemistry of the Flash Hydropyrolysis Process, a rapid gas-phase, non-catalytic coal hydrogenation technique developed at BNL for the conversion to gaseous and liquid fuels. The experimental equipment used for this purpose is a highly instrumented 1 inch down-flow tubular reactor originally designed to operate at up to 4000 psi and 800/sup 0/C, with coal feed up to 1 lb/hr. These conditions are being extended to include temperatures to 900/sup 0/C at pressures equal to or less than 2500 psi and coal feed to 2 lbs/hr. Coal and char analyses are performed on a routine basis. A second distillation curve was performed on the total organic liquid product, this time extending the distillation temperature range to 350/sup 0/C. The results were similar to the first curve indicating that the liquid contains approximately 50% BTX (benzene, toluene, xylene) and 50% heavier hydrocarbons. A major portion of the experimental effort was devoted to the study of the effect of coal particle residence time. A number of exploratory runs were also conducted and results are reported here, including the use of a Battelle Treated Coal (BTC-caking coal treated with CaO), a New Mexico sub-bituminous coal, a mixture of lignite and lignite char and a lignite impregnated with iron.

CE then processes the products into either a coal-water fuel (CVVT) or a dry microfine pulverized coal (DMPC) form for combustion testing. The objectives of this project include: (1) the development of an engineering data base which will provide detailed information on the properties of BCFs influencing combustion, ash deposition, ash erosion, particulate collection, and emissions; and (2) the application of this technical data base to predict the performance and economic impacts of firing the BCFs in various commercial boiler designs. The technical approach used to develop the technical data includes: bench-scale fuel property, combustion, and ash deposition tests; pilot-scale combustion and ash effects tests; and full-scale combustion tests. Subcontractors to CE to perform parts of the test work are the Massachusetts Institute of Technology (MIT), Physical Science, Inc. Technology Company (PSIT) and the University of North Dakota Energy and Environmental Research Center (UNDEERC). Twenty fuels will be characterized during the three-year base program: three feed coals, fifteen BCFS, and two conventionally cleaned coals for full-scale tests. Approximately, nine BCFs will be in dry microfine coal (DMPC) form, and six BCFs will be in coal-water fuel (CWF) form. Additional BCFs would be characterized during optional project supplements.

Solvent Refined Coal (SRC) process. Quarterly technical progress report, January 1979-March 1979  

Science Conference Proceedings (OSTI)

This report summarizes the progress of the Solvent Refined Coal (SRC) Project by the Pittsburg and Midway Coal Mining Co. for the Department of Energy for the period January 1, 1979 to March 31, 1979. 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.

Laboratory study for removal of organic sulfur from coal. Quarterly technical progress report  

SciTech Connect

Substantial progress has been made in the development of the Gravimelt Process for removal of organic sulfur from coal. Three reactors have been fabricated for both material balance studies of the desulfurization of coal with caustic and examination of the behavior of model organic and inorganic sulfur-containing compounds with the same mixture. Model organic sulfur conpounds have been procured and samples of Kentucky No. 9 coal enriched in mineral matter and samples enriched in organic matter have been prepared by float sink techniques for use in determining mechanism and products of the desulfurization reactions. Initial experimentation has been aimed at determining the fate of sulfur removed from coal and obtaining semi-quantitative information for future material balance studies. These studies show near 90% of the sulfur content of the Kentucky No. 9 coal was removed and approximately 3/4 of this removed sulfur was found by chemical analysis to be in the caustic phase. It was further determined that approximately 1% of the coal organic matter dissolves into the caustic phase. These results indicate rough material flows and show that material balance measurements are feasible. A preliminary conceptual engineering design for a full scale Gravimelt coal desulfurization plant was prepared in order to guide future laboratory efforts toward obtaining key engineering data. The engineering study indicates that the Gravimelt Process can be designed utilizing state of the art equipment and that likely energy recovery is approximately 90%. It is estimated that coal desulfurization costs will be in the range of $20 per ton of coal produced, or $.70/10/sup 6/ Btu, in 1980 dollars.

Development and testing of a high efficiency advanced coal combustor phase III industrial boiler retrofit. Quarterly technical progress report No. 9, 1 October 1993--31 December 1993  

SciTech Connect

This report documents the technical aspects of this project during the ninth quarter of the program. During this quarter, the natural gas baseline testing at the Penn State demonstration boiler was completed, results were analyzed and are presented here. The burner operates in a stable manner over an 8/1 turndown, however due to baghouse temperature limitations (300{degrees}F for acid dewpoint), the burner is not operated for long periods of time below 75% load. Boiler efficiency averaged 83.1% at the 100 percent load rate while increasing to 83.7% at 75% load. NO{sub x} emissions ranged from a low of 0.17 Lbs/MBtu to a high of 0.24 Lbs/MBtu. After the baseline natural gas testing was completed, work continued on hardware optimization and testing with the goal of increasing carbon conversion efficiency on 100% coal firing from {approx}95% to 98%. Several coal handling and feeding problems were encountered during this quarter and no long term testing was conducted. While resolving these problems several shorter term (less than 6 hour) tests were conducted. These included, 100% coal firing tests, 100% natural gas firing tests, testing of air sparges on coal to simulate more primary air and a series of cofiring tests. For 100% coal firing, the carbon conversion efficiency (CCE) obtained this quarter did not exceed the 95-96% barrier previously reached. NO{sub x} emissions on coal only ranged from {approx} 0.42 to {approx} 0.78 Lbs/MBtu. The burner has not been optimized for low NO{sub x} yet, however, due to the short furnace residence time, meeting the goals of 98% CCE and <0.6 Lbs/MBtu NO{sub x} simultaneously will be difficult. Testing on 100% natural gas in the boiler after coal firing indicated no changes in efficiency due to firing in a `dirty` boiler. The co-firing tests showed that increased levels of natural gas firing proportionately decreased NO{sub x}, SO{sub 2}, and CO.

Effects of calcium magnesium acetate on the combustion of coal-water slurries. Thirteenth Quarterly project status report, 1 September 1992--30 November 1992  

SciTech Connect

Production of CWF agglomerates of pulverized coal grind has commenced. A bituminous coal PSOC 1451 HVA coal has been obtained from the Penn State Coal Sample Bank, size classified in the 38-45{mu}m range. This coal was mixed with water (40 % solids) and with 1% ammonium lignosulfonate as a dispersant. Generation of pre-dried CWF agglomerates has been conducted in a thermal reactor, as described at an earlier report. The solenoid actuator-driven single drop generator is used fitted with different size needle-plunger combinations. During the present, 14th quarter, the following tasks are being conducted: (a) Measure the gas temperature profiles in the new furnace and recalibrate the pyrometer. (b) Generate an inventory of CWF agglomerates of different coal grinds and carbon black with and without CMA. (c) Conduct high temperature experiments to identify differences in the combustion behavior of agglomerates of different coal grinds, and (d) efforts will be conducted to capture the resulting ash particles for visual observations.

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.

Coal conversion processes. Quarterly report, December 13, 1983-March 12, 1984  

DOE Green Energy (OSTI)

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.

Spin-mapping of coal structures with ESE and ENDOR. First quarterly report  

SciTech Connect

Nondestructive chemical and physical characterization of whole Illinois coal and separated macerals, both before and after treatment by various desulfurization techniques is being performed using new electron magnetic resonance methods. The chemical structures of sulfur and non-sulfur containing organic species are being measured by the technique of HYPERFINE FINGERPRINT SPECTROSCOPY. Data on hyperfine couplings in a separated vitrinite maceral suggest the presence of small, condensed ring aromatic species, which may be linked by aliphatic bridging groups. Results from multi-frequency EPR experiments performed at X-, Q- and W-bands show slightly anisotropic spectra which have been analyzed by theoretical techniques developed in this laboratory. Analysis of the spectra reveals a nearly axial g-matrix, which agrees well with a model of planar conjugated aromatic species. The W-band data represents the first such experiments performed on coal and separated macerals.

Electrostatic beneficiation of coal. Quarterly technical progress report, January 1--March 31, 1996  

SciTech Connect

Two methods of examining the decay rate of charge on powders deposited on the separator plates were examined. In the first method the charge transferred from ground to the separator plate was measured directly with an electrometer after completion of the powder deposition and after turning off the electric field. In a second method an electrostatic field meter (Trek model 354A) was used to measure the field due to the charge on the plates or on thin Teflon or aluminum plates which had been placed over the metal separator plates. In addition the paper discusses the fabrication and use of a resistivity cell for coal powder; charging of small particles by milling; observations with silica gel; and a review of articles on particle charging. A separate section presents the electrostatic charging properties of coal macerals.

Flash hydropyrolysis of coal. Quarterly report No. 2, April 1--June 30, 1977  

DOE Green Energy (OSTI)

With the combination of low hydrogen to coal ratio, high coal feed rate and larger total quantity of coal fed, considerable liquid product is being condensed and collected. Experimental runs conducted at 750/sup 0/C and 800/sup 0/C at pressures up to 3000 psi of hydrogen show overall hydrocarbon yields and particularly gaseous hydrocarbon yields to increase with pressure to approximately 60 percent at 3000 psi. At 750/sup 0/C approximately one third (20 percent) of this yield is in the form of liquid products (half BTX and half greater than or equal to C/sub 9/) while at 800/sup 0/C the yield is almost all methane with less than 3 percent of liquids produced. Preliminary results of the effect of residence time on product yield and distribution shows that at 3000 psi of hydrogen and 800/sup 0/C, gaseous product yield increase and liquid yields decrease as the residence time is increased from 2.3 to 9.2 seconds. Under almost identical conditions at 750/sup 0/C, all product yields increased with approximately the same increase in residence time. Economic studies of the Flash Hydropyrolysis Process (FHP) are continuing. A detailed analysis of a 25,000 ton/day coal conversion plant utilizing FHP shows the discounted cash flow (DCF) to be strongly dependent upon the operating pressure of the reactor, increasing by almost a factor of two as the pressure is reduced from 4000 psi to 500 psi. The DCF is also shown to be influenced by the distribution of products, increasing as the yields of liquids increase.

Coal-fired high performance power generating system. Quarterly progress report  

SciTech Connect

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.

Rheological properties essential for the atomization of coal water slurries (CWS). Quarterly progress report, December 15, 1994--March 15, 1995  

SciTech Connect

The overall objective of this project is to perform experiments to understand the effect of high shear and extensional properties on the atomization of coal-water slurries (CWS). In the atomization studies, the mean drop size of the CWS sprays will be determined at various air-to CWS. A correlation between the extensional and high shear properties, particle size distributions and the atomization will be made in order to determine the influence of these parameters on the atomization of CWS. During the past quarter, further rheological testing were performed on CWS samples that had been prepared and stored for a period of three months. The testing included low and high shear measurements as well as dynamic oscillatory measurements. The CWS tested were PSOC-1527 from Middle Kittaning, PSOC-1472 from Lower Banner and PSOC-1475 (Elkhorn No. 3). These tests were performed in order to delineate any differences in rheological properties due to aging, and how this differences will influence subsequent atomization of the slurries. The test results obtained on PSOC-1527 and 1472, showed slight variations in their rheological behavior when compared to previously obtained data on the same samples. The data obtained on PSOC-1475, however showed no significant variation.

Bioconversion of coal derived synthesis gas to liquid fuels. Quarterly technical progress report, 1 April--30 June 1994  

DOE Green Energy (OSTI)

The overall objective of the project is to develop an integrated two-stage fermentation process for conversion of coal-derived synthesis gas to a mixture of alcohols. This is achieved in two steps. In the first step, Butyribacterium methylotrophicum converts carbon monoxide (CO) to butyric and acetic acids. Subsequent fermentation of the acids by Clostridium acetobutylicum leads to the production of butanol and ethanol. The tasks for this quarter were: development/isolation of superior strains for fermentation of syngas; evaluation of bioreactor configuration for improved mass transfer of syngas; recovery of carbon and electrons from H{sub 2}-CO{sub 2}; initiation of pervaporation for recovery of solvents; and selection of solid support material for trickle-bed fermentation. Technical progress included the following. Butyrate production was enhanced during H{sub 2}/CO{sub 2} (50/50) batch fermentation. Isolation of CO-utilizing anaerobic strains is in progress. Pressure (15 psig) fermentation was evaluated as a means of increasing CO availability. Polyurethane foam packing material was selected for trickle bed solid support. Cell recycle fermentation on syngas operated for 3 months. Acetate was the primary product at pH 6.8. Trickle bed and gas lift fermentor designs were modified after initial water testing. Pervaporation system was constructed. No alcohol selectivity was shown with the existing membranes during initial start-up.

Computational tools for pulverized-coal combustion. Third quarterly report, October 1981-December 1981  

Science Conference Proceedings (OSTI)

This report summarizes the work conducted to develop and verify a computer code capable of modeling the major aspects of pulverized-coal combustion. Achieving this objective will lead to design methods applicable to industrial and utility furnaces. The combustion model (COMO) consists of a number of relatively independent modules that represent the major processes involved in pulverized-coal combustion. These modules will be continually upgraded over the course of the contract. Three distinct versions of the COMO will be developed over the duration of the contract. Version 1 of COMO will model all of the major features of pulverized-coal combustion but with a number of simplifying assumptions. It will be used primarily to determine a satisfactory means of integrating the numerical models of the combustion processes into an overall combustion model, since this is perhaps the major challenge. Later versions will relax these assumptions and incorporate state-of-the-art combustion information. Guidelines were prepared and reviewed to allow process modules to be developed relatively independently, while providing for the subsequent integration of these modules into COMO. The formulation and coding of the Version 1 gas-phase turbulence, chemistry and radiation models were completed. Test cases were run for each model, and good agreement was obtained with other analyses and with data when available. A formal method for documenting COMO was investigated, and preliminary specifications were developed.

Refining and end use study of coal liquids. Quarterly report, July-- September 1995  

Science Conference Proceedings (OSTI)

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 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. 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 effects of moderate coal cleaning on the microbial removal of organic sulfur. [Quarterly] technical report, March 1, 1992--May 30, 1992  

SciTech Connect

The purpose of this project is to investigate the possibilities of developing an integrated physical/chemical/microbial process for the precombustion removal of sulfur from coal. Microorganisms are capable of specifically cleaving carbon-sulfur bonds and removing substantial amounts of organic sulfur from coal; however, the removal of organic sulfur from coal by microorganisms is hampered by the fact that, as a solid substrate, it is difficult to bring microorganisms in contact with the entirety of a coal sample. This study will examine the suitability of physically/chemically treated coal samples for subsequent biodesulfurization. During this quarter tests were performed involving prolonged (7 day) exposure to chemical comminution agents followed by explosive comminution. Combined chemical plus physical comminution yielded only minor differences between the chemical treatments tested (0.lN NAOH, methanol plus 0.lN NAOH, isopropanol plus 0.lN NAOH, and ammonia vapor) as regards particle size distribution. The densities of treated products varied somewhat with 0.lN NaOH and ammonia yielding the lowest and highest densities respectively. Biodesulfurization tests indicate that pre-grown IGTS8 biocatalysts can be used to desulfurized chemically treated IBC-107 coal.

Combustion characterization of coals for industrial applications. Fourth quarterly progress report, January 1-March 31, 1983  

SciTech Connect

The Controlled Mixing History Furnace (CMHF) testing of the Alabama high volatile A bituminous coal was completed in December 1982. The main goal of the CMHF testing is to determine the effect of staged combustion on NO/sub x/ emissions control and its influence on overall combustion efficiency and to provide scale up information for extrapolating Drop Tube Furnace System results. The parameters studied include: (1) primary stage stoichiometry, (2) primary stage residence time, and (3) overall excess air level. In addition, one test was conducted on a finer grind coal (87% through 200 mesh) under optimum NO/sub x/ conditions to study the effect of particle size on NO/sub x/ emissions and carbon burnout. Based on this pilot scale study on the Arkadelphia coal, it can be concluded that a judicious use of staged combustion leads to an effective control of NO/sub x/ emissions without adversely affecting the overall fuel combustion efficiency. Specific conclusions follow. Both primary stage stoichiometry and primary stage residence time are very important parameters for controlling NO/sub x/ emissions. At 20% overall excess air: (1) an optimum primary stage stoichiometry of 50% of theoretical air, at a primary stage residence time of 1.45 seconds brought about a 43% reduction in NO/sub x/ compared to the unstaged baseline case; and (2) a primary stage residence time of 1.56 seconds, at a primary stage stoichiometry of 50% led to a 50% reduction in NO/sub x/ compared to the same unstaged baseline case. The effect of excess air on NO/sub x/ emissions under an optimum primary stage stoichiometry condition is moderate but significant. Increasing the excess air from 0 to 35%, while holding the primary stage stoichiometry constant at 50%, led to an increase in NO/sub x/ of 27%. 8 figures, 2 tables.

Coal-fired high performance power generating system. Quarterly progress report  

Science Conference Proceedings (OSTI)

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 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.

Production of low sulfur binder pitich from high-sulfur Illinois coals. Quarterly report, 1 March 1995--31 May 1995  

SciTech Connect

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.

Flash hydropyrolysis of coal. Quarterly report No. 3, July 1, 1977--September 30, 1977  

DOE Green Energy (OSTI)

The program is designed to study the process variables and chemistry of the Flash Hydropyrolysis Process, a rapid gas-phase, non-catalytic coal hydrogenation technique developed at BNL. The equipment used is a 1 lb/hr unit utilizing a 1 inch down flow tubular reactor designed to operate at up to 4000 psi and 800/sup 0/C. This equipment has been in operation for more than a year with only one problem. All the data to date on product yield as a function of temperature and hydrogen pressure is correlated in 4 tables and plotted in a series of 9 figures. The total liquid yields appear to reach a maximum of approximately 20% at 750/sup 0/C with only slight increase with hydrogen pressures above 2000 psi. Approximaly half of this yield is BTX. The ethane yield also appears to maximize between 700 and 750/sup 0/C but continues to increase with increased pressure. Methane yields are shown to continue to increase with both temperature and hydrogen pressure. Total carbon conversion under these conditions approximated 60%. The pyrolysis of lignite using helium in the system shows a five to ten fold decrease in the yields of CH/sub 4/, C/sub 2/H/sub 6/ and C/sub 6/H/sub 6/ compared to flash hydropyrolysis under hydrogen pressure. Preliminary experiments were conducted at 750 and 800/sup 0/C to determine the effect of coal particle residence time on product yields and distribution. The results indicate that at 750/sup 0/C both liquid and gaseous yields increase from 45% to 52% as the residence time is increased by a factor of four from 2.3 to 9.2 seconds. However, at 800/sup 0/C under similar conditions, little change in total yield (60%) is observed but the liquid yield decreases from approximately 4% to 1% with a corresponding increase in gaseous products.

Preconversion processing of bituminous coals: New directions to improved direct catalytic coal liquefaction. Quarterly report, July 1, 1992--September 30, 1992  

SciTech Connect

Soaking coal in coal liquids at 300-400{degrees}C (high-tenperature soaking) has been studied for coal dissolution prior to liquefaction in the previous task. Two high-volatile bituminous coals, Illinois No. 6 and Pittsburgh No. 8, were examined in three different coal liquids. The high-temperature soaking was effective to solubilize more than 70 wt% cf these coals. The mechanism of disintegration of coal by the high-temperature soaking was investigated under various soaking conditions. The products was also analyzed with solvent swelling. These results were rationalized that coal is solubilized primarily by physical disintegration. The derived mechanism was consistent with the new concept of coal structure: A significant portion of coal is physically associated, not three-dimensionally cross-linked. Radically-induced scission reactions were proposed to prorate breakage of coal moleculs by the combination of the high-temperature soaking before liquefaction. In this term, the effect of radical initiators were investigated under the conditions of the high-temperature soaking and liquefaction. Illinois No. 6 coal and a coal liquid derived from the same coal were used. The first section reports the effect of radical initiators on coal disintegration, and the second section reports the effect of a radical initiator on coal liquefaction. Radical initiators had a positive effect on disintegration. However, the effect was highly temperature-dependent and had a negative effect on liquefaction at high tenperatures.

SciTech Connect

This advanced combustion system research program is for the development of innovative coal-fired process heaters which can be used for high temperature melting, smelting and waste vitrification processes. The process heater systems to be developed have multiple use applications; however, the Phase 3 research effort is being focused on the development of a process heater system to be used for producing value added vitrified glass products from boiler/incinerator ashes and industrial wastes. The primary objective of the Phase 3 project is to develop and integrate all the system components, from fuel through total system controls, and then test the complete system in order to evaluate its potential marketability. During the past quarter, the major effort was completing some of the system modification installation designs, completing industry funded testing, developing a surrogate TSCA ash composition, and completing the TSCA ash Test Plan. The installation designs will be used for the equipment modifications planned for the end of CY 93. The industry funded testing consisted of vitrifying Spent Aluminum Potliner (SPL) which is a listed hazardous waste. This testing has verified that SPL can be vitrified into a safe, recyclable glass product. Some results from this testing are provided in Section 2.2.1. The surrogate TSCA ash composition was developed with input from various DOE laboratories and subcontractors. The surrogate ash consists of a mixture of MSW fly ash and bottom ash spiked with heavy metal contaminants. The levels of metal additives are sufficient to ascertain the partitioning of the contaminants between the glass and effluent flow streams. Details of the surrogate composition and the planned testing is provided in Section 4.2.2.

Synthesis of acrylates and methacrylates from coal-derived syngas. Quarterly report, October--December 1996  

SciTech Connect

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.

The primary objective of the Healy Clean Coal Project (HCCP) is to conduct a cost-sharing project that will demonstrate a new power plant design which features innovative integration of an advanced combustor and heat recovery system coupled with both high- and low- temperature emission control processes. The primary equipment elements comprising this new power plant design includes entrained combustion systems coupled with a boiler which will produce low- NO{sub x} levels, and function as a limestone calciner and first-stage SO{sub 2} remover in addition to its heat recovery function; a single spray dryer absorber vessel for second-stage sulfur removal; a baghouse for third-stage sulfur and particulate removal; and a lime activation system which recovers unused reagent from particulate collected in the baghouse. The emission levels of SO{sub 2}, NO{sub x}, and particulate to be demonstrated are expected to be less than the Federal New source Performance Standards. The plant design is finalized and all Federal and State permits have been obtained for construction of the project. Construction of the project is on schedule and is within the budget established following the award of the general construction contract. Off-site manufacturing of equipment, including combustor supply and flue gas desulfurization system supply is progressing on schedule and as budgeted.

The primary objective of the Healy Clean Coal Project is to conduct a cost-sharing project that will demonstrate a new power plant design which features innovative integration of an advanced combustor and heat recovery system coupled with both high- and low-temperature emission control processes. The parties anticipate that if the demonstration project is successful, the technology could become commercialized in the near term and will be capable of (1) achieving significant reductions in the emissions of sulfur dioxide (SO{sub 2}) and the oxides of nitrogen (NO{sub x}) from existing facilities to minimize environmental impacts such as transboundary and interstate pollution and/or (2) providing for future energy needs in an environmentally acceptable manner. The plant design is finalized and all Federal and State permits have been obtained for the construction of the project. Construction of the project is on schedule and is within the budget established following the award of the general construction contract. Off-site manufacturing of equipment, including combustor supply and flue gas desulfurization system supply, is progressing on schedule and as budgeted. This progress report will summarize the significant project development steps taken in the reporting period.

Preconversion processing of bituminous coals: New directions to improved direct catalytic coal liquefaction. Quarterly report, April 1, 1992--June 30, 1992  

SciTech Connect

A study of high-temperature soaking has been continued. Two high-volatile bituminous coals and three coal liquids were used. Large pyridine extractabilities of more than 70 wt% were obtained for aR cases. A better understanding Of the mechanism is important for the development of coal preconversion using the high-temperature soaking. To investigate the mechanism of the change in coal solubilization by high-temperature soaking, a simple soaking experiment was conducted. The extract from the Illinois No. 6 coal was treated in toluene at three different temperatures, and the treated samples were analyzed by coal swelling using the recently developed method. Furthermore, effects of soaking time, soaking temperature, soluble portions, and coal rank were examined by using actual coal liquids. Although a cross-linked, three-dimensional macromoleculer model has been widely accepted for the structure of coat it has previously been reported that significant portions (far more generally believed) of coal molecules are physically associated. It is known, as reviewed in that paper, that most portions of bituminous coal can be disintegrated in coal derived liquids and polycyclic aromatic hydrocarbons at 300--400{degrees}C (high-temperature soaking). It was proposed that electron donors and acceptors of low molecular mass contained in these materials substitute coal-coal complexes with charge-transfer interactions. This is physical dissociation of associated coal molecules. However, chemical reactions may occur at these temperatures.

Quarterly technical progress report No. 2, December 20-March 19, 1982. Second quarterly report on the effect of rapid heating rate on coal nitrogen and sulfur release  

Science Conference Proceedings (OSTI)

A laser pyrolysis technique is applied to the investigation of the effects of heating rate on release of coal-bound sulfur and nitrogen. An experimental system characterization and calibration has been completed. A detailed documentation was prepared describing the 3-color pyrometer and the data analysis technique. The coal particle feed system has been calibrated to provide accurate mass flow rate at pre-selected particle velocities. The first batch of samples submitted for chemical analysis will be used for the determination of kinetics parameters at a high heating rate (approximately equal to 10/sup 6/ K/s). The coal used presently is a Montana Rosebud. Two other coals are available; one is ILL No. 6 (through EERC) which will need to be pulverized and the second is a Pitt. hv-A (through KVB). It was confirmed that sieve and drag size distribution of coal differ significantly, and that particle shape effects may be significant in the modelling of particle dynamics.

Advanced liquefaction using coal swelling and catalyst dispersion techniques. Quarterly technical progress report No. 7, April 1993--June 1993  

Science Conference Proceedings (OSTI)

The overall objective of this project is to develop a new approach for the direct liquefaction of coal to produce an all-distillate product slate at a sizable cost reduction over current technology. The approach integrates coal selection, pretreatment, coal swelling with catalyst impregnation, liquefaction, product recovery with characterization, alternate bottoms processing, and carrying out a technical assessment including an economic evaluation. The project is being carried out under contract to the United States Department of Energy. All three coals used in this study (Black Thunder, Burning Star bituminous, and Martin Lake lignite) are effectively swelled by a number of solvents. The most effective solvents are those having hetero-functionality. In addition, a synergistic effect has been demonstrated, in which solvent blends are more effective for coal swelling than the pure solvents alone. Therefore, it will be necessary to use only low levels of swelling agents and yet promote the impregnation of catalyst precursors. The rate of the impregnation of catalyst precursors into swollen coal increases greatly as the effectiveness of the solvent to swell the coal increases. This effect is also demonstrated by improved catalyst precursor impregnation with increased contact temperature. Laboratory- and bench-scale liquefaction experimentation is underway using swelled and catalyst impregnated coal samples. Higher coal conversions were observed for the SO{sub 2}-treated coal than the raw coal, regardless of catalyst type. Conversions of swelled coal were highest when Molyvan-L, molybdenum naphthenate, and nickel octoate, respectively, were added to the liquefaction solvent.

Improvement of storage, handling, and transportability of fine coal. Quarterly technical progress report number 8, October 1--December 31, 1995  

SciTech Connect

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. On the other hand, Mulled Coal does not cause the fugitive and airborne dust problems normally associated with thermally dried coal. The objectives of this project are to demonstrate that: the Mulled Coal process, which has been proved to work on a wide range of wet fine coals at bench scale, will work equally well on a continuous basis, producing consistent quality, and 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.

Thermodynamic properties of pulverized coal during rapid heating devolatilization processes. Quarterly progress report, April--June 1993  

Science Conference Proceedings (OSTI)

Knowledge of the thermodynamic and morphological properties of coal associated with rapid heating decomposition pathways is essential to progress in coal utilization technology. Specifically, knowledge of the heat of devolatilization, surface area and density of coal as a function of rank characteristics, temperature and extent of devolatilization in the context of rapid heating conditions is essential to the fundamental determination of kinetic parameters of coal devolatilization. These same properties are also needed to refine existing devolatilization sub-models utilized in large-scale modeling of coal combustion systems. The objective of this research is to obtain data on the thermodynamic properties and morphology of coal under conditions of rapid heating. Specifically, the total heat of devolatilization, external surface area, BET surface area and true density will be measured for representative coal samples. The coal ranks to be investigated will include a high volatile A bituminous (PSOC 1451 D) and a low volatile bituminous (PSOC 1516D). An anthracite (PSOC 1468) will be used as a non-volatile coal reference. In addition, for one coal, the contribution of each of the following components to the overall heat of devolatilization will be measured: the specific heat of coal/char during devolatilization, the heat of thermal decomposition of the coal, the specific heat capacity of tars, and the heat of vaporization of tars.

Integrated low emissions cleanup system for direct coal fueled turbines (moving bed, fluid bed contactor/ceramic filter). Eighteenth quarterly status report, January--March 1992  

SciTech Connect

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 nEC 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 eighteenth quarter to develop this ILEC technology for direct coal-fired turbine power plants.

Advanced liquefaction using coal swelling and catalyst dispersion techniques. Quarterly technical progress report, July--September 1992  

Science Conference Proceedings (OSTI)

The experimental study of coal swelling ratios have been determined with a wide variety of solvents. Only marginal levels of coal swelling were observed for the hydrocarbon solvents, but high levels were found with solvents having heteroatom functionality. Blends were superior to pure solvents. The activity of various catalyst precursors for pyrene hydrogenation and coal conversion was measured. Higher coal conversions were observed for the S0{sub 2}-treated coal than the raw coal, regardless of catalyst type. Coal conversions were highest for Molyvan-L, molybdenum naphthenate, and nickel octoate, respectively. Bottoms processing consists of a combination of the ASCOT process coupling solvent deasphalting with delayed coking. Initial results indicate that a blend of butane and pentane used near the critical temperature of butane is the best solvent blend for producing a yield/temperature relationship of proper sensitivity and yet retaining an asphalt phase of reasonable viscosity. The literature concerning coal swelling, both alone and in combination with coal liquefaction, and the use of dispersed or unsupported catalysts in coal liquefaction has been updated.

Coal plasticity at high heating rates and temperatures. First technical progress report for the fourth quarter 1989  

SciTech Connect

The broad objective of this project is to obtain improved, quantitative understanding of the transient plasticity of bituminous coals under high heating rates and other reaction and pretreatment conditions of scientific and practical interest. To these ends the research plan is to measure the softening and resolidification behavior of two US bituminous coals with a rapid-heating, fast response, high-temperature coal plastometer, previously developed in this laboratory. Specific measurements planned for the project include determinations of apparent viscosity, softening temperature, plastic period, and resolidificationtime for molten coal: (1) as a function of independent variations in coal type, heating rate, final temperature, gaseous atmosphere (inert, 0{sub 2} or H{sub 2}), and shear rate; and (2) in exploratory runs where coal is pretreated (preoxidation, pyridine extraction, metaplast cracking agents), before heating. The intra-coal inventory and molecular weight distribution of pyridine extractables will also be measured using a rapid quenching, electrical screen heater coal pyrolysis reactor. The yield of extractables is representative of the intra-coal inventory of plasticing agent (metaplast) remaining after quenching. Coal plasticity kinetics will then be mathematically modeled from metaplast generation and depletion rates, via a correlation between the viscosity of a suspension and the concentration of deformable medium (here metaplast) in that suspension. Work during this reporting period has been concerned with re-commissioning the rapid heating rate plastometer apparatus.

Combustion characterization of the blend of plant coal and recovered coal fines. [Quarterly] technical report, March 1, 1992--May 31, 1992  

SciTech Connect

The overall objective of this proposed research program is to determine the combustion characteristics of the blend derived from mixing a plant coal and recovered and clean coal fines from the pond. One plant coal and three blend samples will be prepared and utilized. The blend samples will be of a mixture of 90% plant coal + 10% fines, 85% plant coal + 15% fines, 80% plant coal + 20% fines having particle size distribution of 70% passing through -200 mesh size. These samples` combustion behavior will be examined in two different furnaces at Penn State University, i.e., a down-fired furnace and a drop-tube furnace. The down-fired furnace win be used mainly to measure the emissions and ash deposition study, while the drop tube furnace will be used to determine burning profile, combustion efficiency, etc. The burning profile of the plant coal and the three blends was determined in a thermogravimetric analyzer. Results indicated slower burning of the blends due to low volatile matter and oxidized coal particles. Ash fusing temperatures of the samples were determined using ASTM procedure. Preliminary combustion evaluation of the samples (100% plant coal, 80% plant coal/20% recovered coal fines) indicated that the flame was stable at 100,000-200,000 Btu/hr firing rate. Carbon conversion efficiency of 85 to 90% was recorded using the Ash Tracer technique. Tests are continuing to determine the operating boundaries for these blends while measuring the emissions of SO{sub x}, NO{sub x}, CO and O{sub 2}, maintaining a stable flame.

Thermodynamic properties of pulverized coal during rapid heating devolatilization processes. Quarterly progress report, January--March 1993  

SciTech Connect

Knowledge of the thermodynamic and morphological properties of coal associated with rapid heating decomposition pathways is essential to progress in coal utilization technology. Specifically, knowledge of the heat of devolatilization, surface area and density of coal as a function of rank characteristics, temperature and extent of devolatilization in the context of rapid heating conditions is required both, for the fundamental determination of kinetic parameters of coal devolatilization, and to refine existing devolatilization sub-models used in comprehensive coal combustion codes. The objective of this research is to obtain data on the thermodynamic properties and morphology of coal under conditions of rapid heating. Specifically, the total heat of devolatilization, external surface area, BET surface area and true density will be measured for representative coal samples. In addition, for one coal, the contribution of each of the following components to the overall heat of devolatilization will be measured: the specific heat of coal/char during devolatilization, the heat of thermal decomposition of the coal, the specific heat capacity of tars, and the heat of vaporization of tars. Morphological characterization of the parent coal samples has been completed by the University of Pittsburgh. Results are presented for true density, CO{sub 2} surface area, mercury porosimetry, and particle size and shape measurements using image analysis. The heat of thermal decomposition of PSOC 1451D (Task 5) will be calculated from the data reported here. The Task 10 effort, Morphological Characterization of Coal/Char Samples as a Function of Extent of Devolatilization, will continue at the University of Pittsburgh. Work will focus on measurement of the morphological characteristics of the char samples as a function of extent of reaction.

The use of solid-state NMR techniques for the analysis of water in coal and the effect of different coal drying techniques on the structure and reactivity of coal. Quarterly report, March 1, 1994--May 31, 1994  

SciTech Connect

One area for improvement in the economics of coal liquefaction is coal drying, particularly for the lower rank coals. However, there is considerable evidence to show that drying has a detrimental effect on the liquefaction behavior of coals. Regarding the liquefaction of coal, there does not appear to have been any systematic study of the methods of coal drying on coal structure and the role water plays in enhancing or lessening coal reactivity toward liquefaction. For the research program reported here, different methods of drying are being investigated to determine if drying can be accomplished without destroying coal reactivity toward liquefaction. In an effort to understand the mechanism of water for enhancing coal liquefaction yield, the reactions of D{sub 2}O with the molecular constituents of coal during coal liquefaction are being investigated. This study involves the use of solution-state deuterium NMR, as well as, conventional solution-state {sup 1}H and {sup 13}C NMR analyses of the coal, and the coal liquids and residue from a coal liquefaction process. These D{sub 2}O transfer reactions will be conducted on coals which have been dried by various methods and rehydrated using D{sub 2}O and by successive exchange of H{sub 2}O associated with the coals with D{sub 2}O. The drying methods include thermal, microwave, and chemical dehydration of the coal.

High temperature electrochemical polishing of H{sub 2}S from coal gasification process streams. Quarterly progress report, October 1, 1995--December 31, 1995  

DOE Green Energy (OSTI)

An advanced process for the separation of hydrogen sulfide (H{sub 2}S) from coal gasification product streams through an electrochemical membrane is being developed. H{sub 2}S is removed from the syn-gas stream, split into hydrogen, which enriches the exiting syn-gas, and sulfur, which is condensed from an inert sweep gas stream. The process allows removal of H{sub 2}S without cooling the gas stream and with negligible pressure loss through the separator. The process is made economically attractive by the lack of need for a Claus process for sulfur recovery. Membrane manufacturing coupled with full-cell experimentation was the primary focus this quarter. A tape-casted zirconia membrane was developed and utilized in one full-cell experiment (run 25); run 24 utilized a fabricated membrane purchased from Zircar Corporation. Results are discussed.

The economical production of alcohol fuels from coal-derived synthesis gas. Quarterly technical progress report number 12, July 1--September 30, 1994  

DOE Green Energy (OSTI)

Both plug-flow microreactor systems at WVU are now functioning. Screening runs on these systems were started using carbide and nitride catalysts first, to avoid any question of contamination of the system with sulfur. The carbide and nitride catalysts are characterized by high activity but low selectivity towards alcohols. The Chevrel-phase catalysts tested have much lower activities but may be more selective to alcohols. Catalyst synthesis procedures are attempting to offset this tendency, and also to characterize and prepare sulfide catalyst by other approaches. At UCC and P, test runs on the reactor system have commenced. Higher alcohols up to butanol were observed and identified at high temperatures. Modeling studies have concentrated on the catalytic membrane reactor. The topical report, originally submitted last quarter, was revised after some errors were found. This report includes the design and economics for the seven cases discussed in previous quarterly reports. In the topical report, it is shown that a judicious choice of coal:natural gas feed ratio to the alcohol synthesis process allows the Shell Gasifier to be nearly competitive with natural gas priced at of $3.00/MMBtu. The advantage of the Shell Gasifier over the Texaco Gasifier is that the former produces a syngas with a lower H{sub 2}:CO ratio. When the feed to the process is coal only, there is no difference in the projected economics that would favor one gasifier over the other. The potential of co-generation of electric power with high alcohol fuel additives has been investigated. Preliminary results have revealed that a once-through alcohol synthesis process with minimal gas clean-up may provide an attractive alternative to current designs given the prevailing economic status of IGCC units.

Effects of surface chemistry on the porous structure of coal. Quarterly technical progress report, October 1995--December 1995  

SciTech Connect

The primary objective of this work is to use {sup 129}Xe NMR to characterize the microporous structure of coals. As an aide in this characterization, which is by no means straightforward, another objective is to combine this technique with volumetric adsorption techniques and track the effect of controlled opening of the micropores in a microporous carbon by oxygen chemisorption/desorption. The primary goal of the NMR work is to measure the micropore sizes in coal; more broadly, it is to better tailor the {sup 129}Xe NMR method for use with coal, and to investigate other ways it may be used to describe pore structure in coal, with emphasis on determining whether micropores in coal are connected or isolated. In terms of the primary objectives of the project, the {sup 129}Xe NMR spectra with pressure variation have been obtained for two more coals, completing this task for the sample set of six coals. In terms of the broad objectives of the project, examination of the influence on the xenon signal of packing the powdered coal has been undertaken. These data are of potential value for the determination of whether the porosity is open or closed. Results of powder density and related experiments will be used in the final interpretation of our current data, including the determination of whether, in the NMR of loose powdered, the chemical shift is indicative of the ``true`` gas-solid interaction.

Combustion characterization of coals for industrial applications. First quarterly progress report, 1 April 1982-30 June 1982  

SciTech Connect

Three of the five coals ear-marked for this study have been characterized. These coals include (1) A Montana (Rosebud) subbituminous; (2) An Illinois (No. 6) high volatile bituminous; and (3) A Pennsylvania (Buck Mountain) anthracite. Samples for analyses were prepared in accordance with the ASTM standard (ASTM D 2013-72). The following ASTM analyses were performed on each coal: proximate, ultimate, higher heating value, Hardgrove grindability index, ash fusibility, and ash composition. Additionally, the flammability index (FI) of each coal was determined in an in-house apparatus. The (FI) is indicative of the ignition temperature of a given fuel on a relative basis. These analyses yielded information regarding the ASTM classification of the three coals as well as their chemical, physical, and ignitibility characteristics. 1 figure, 2 tables.

A characterization and evaluation of coal liquefaction process streams. Quarterly technical progress report, October 1--December 31, 1995  

DOE Green Energy (OSTI)

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. During this reporting period, CONSOL completed analyses of 81 feed and process stream samples from HTI bench Run CMSL-9. HTI liquefaction bench unit Run CMSL-9 (227-87) was operated with all-dispersed catalyst and Black Thunder Mine (Wyodak and Anderson seam) coal, with and without mixed plastics or high density polyethylene (HDPE) as coprocessing feedstocks. The dispersed catalysts used were Molyvan A and HTI`s iron catalyst, a sulfated iron hydroxide. Results are discussed in this report.

Protocols for the selective cleavage of carbon-sulfur bonds in coal. Quarterly report, September 1, 1991--November 30, 1991  

SciTech Connect

Removal of the organic sulfur in coal constitutes one of the major challenges facing fossil fuel scientists today. A cost--effective of desulfurizing Illinois coal is non-existent at the present time. Research in our group aims to develop a simple protocol for sulfur removal by gaining understanding of how various additives can enhance the rates of C-S bond cleavage in Illinois coal and coal model compounds, relative to fragmentation of the coal macromolecule via C-C, C-O, and C-N bond cleavage. During this funding period, we plan to carry out examinations of: (a) the effects of various reaction conditions on radical-initiated and Lewis acid-catalyzed C-S bond cleavages; (b) the effects of caustic impregnation and subsequent alcoholic reflux on C-S bond cleavage strategies; (c) the reactions of coal model compounds with electron-deficient substrates; (d) examinations of photooxidative C-S bond cleavage reactions; (e) the effects of moderate (300--400{degrees}C) temperatures and pressures as well as ultrasonic radiation on (a) - (c). Also planned are differential scanning calorimetric (DSC) examinations of selected C-S bond cleavage protocols, including those on Illinois coals that possess varying amounts of organic and inorganic sulfur.

Novel carbons from Illinois coal for natural gas storage. Quarterly report, 1 December 1994--28 February 1995  

DOE Green Energy (OSTI)

The goal of this project is to develop a technology for producing microengineered adsorbent carbons from Illinois coal and to evaluate the potential application of these novel materials for storing natural gas for use in emerging low pressure, natural gas vehicles (NGV). The focus of the project is to design and engineer adsorbents that meet or exceed the performance and cost targets established for low-pressure natural gas storage materials. Potentially, about two million tons of adsorbent could be consumed in natural gas vehicles by year 2000. If successful, the results obtained in this project could lead to the use of Illinois coal in a sowing and profitable market that could exceed 6 million tons per year. During this reporting period, a series of experiments were made to evaluate the effect of coal pre-oxidation, coal pyrolysis, and char activation on the surface area development and methane adsorption capacity of activated carbons/chars made from IBC-102. The optimum production conditions were determined to be: coal oxidation in air at 225C, oxicoal (oxidized coal); devolatilization in nitrogen at 400C; and char gasification in 50% steam in nitrogen at 850C. Nitrogen BET surface areas of the carbon products ranged from 800--1100 m{sup 2}/g. Methane adsorption capacity of several Illinois coal derived chars and a 883 m{sup 2}/g commercial activated carbon were measured using a pressurized thermogaravimetric analyzer at pressures up to 500 psig. Methane adsorption capacity (g/g) of the chars were comparable to that of the commercial activated carbon manufactured by Calgon Carbon. It was determined that the pre-oxidation is a key processing step for producing activated char/carbon with high surface area and high methane adsorption capacity. The results to date are encouraging and warrant further research and development in tailored activated char from Illinois coal for natural gas storage.

Effect of coal beneficiation process on rheology/atomization of coal water slurries. Quarterly progress report, April 1, 1995--June 30, 1995  

SciTech Connect

The overall objective of this project is to perform experiments to understand the effect of coal beneficiation processes and high shear rheological properties on the atomization of coal-water slurries (CWS). In the atomization studies, the mean drop size of the CWS sprays will be determined at various air to CWS. A correlation between the high shear rheological properties, particle size distributions and the atomization will be made in order to determine the influence of these parameters on the atomization of CWS. Rheological properties of the CWS samples were determined after a six month storage period and the properties compared to freshly prepared samples. The rheological evaluations made include: flow characteristics under low shear rates; flow characteristics under high shear rates; and viscoelastic behavior under low frequency of oscillations. All the three CWS samples formed a hard pack solid at the end of the six month storage period, and had to be redispersed. The flotation cleaned coal and the heavy-media cleaned coal however, had the tendency to settle much faster than the uncleaned coal. Each of them remained completely dispersed during the duration of the testing period.

Rheological properties essential for the atomization of coal water slurries (CWS). Quarterly progress report, September 15, 1992--December 15, 1992  

SciTech Connect

During the previous quarter, it was noted that understanding the rheology of polymeric additives used in enhancing the stability of the CWS was essential in meeting the project objectives. Thus, further review of the literature was carried out to gain information on the rheology of polymeric additives, particularly at high shear rates. Philippoff and Hess [1] reported the existence of four distinct flow regions in the behavior of flow curve analysis of polymer solutions (Figure 1). These regions are characterized by (1) A Newtonian Region; (2) A non-Newtonian pseudoplastic region; (3) A second Newtonian region at high shear rates 10{sup 5} to 10{sup 6} sec{sup {minus}1}; (4) and a region of steepening slope identified as the onset of turbulence. Efforts during this past quarter were therefore directed towards the study of high shear rheology of the CWS.

Field study of disposed wastes from advanced coal processes. Quarterly technical progress report, April--June 1992  

Science Conference Proceedings (OSTI)

The Department of Energy/Morgantown Energy Technology Center (DOE/METC) has initiated research on the disposal of solid wastes from advanced coal 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. There has been considerable research on the characteristics and laboratory leaching behavior of coal wastes -- a lesser amount on wastes from advanced coal processes. However, very little information exists on the field disposal behavior 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.

Refining of fossil resin flotation concentrates from Western coal. Final fifth quarterly report, January 1, 1994--March 31, 1994  

SciTech Connect

Fossil resins occurring in the Wasatch Plateau coal field are composed mainly of aliphatic components, partially aromatized multi-cyclic terpenoids and a few oxygen functional groups (such as {minus}OH and {minus}COOH). The solvent extracted resins show the presence of a relatively large number of methyl groups when compared to the methylene groups, and this indicates the presence of extensive tertiary carbon and/or highly branching chains. In contrast coal consists primarily of aromatic ring structures, various oxygen functional groups ({minus}OH, >C=O, {minus}C{minus}O) and few aliphatic chains. The color difference observed among the four resin types is explained by the presence of chromophores (aromatized polyterpenoid) and also by the presence of finely dispersed coal particle inclusions in the resin matrix. The hexane soluble resin fraction has few aromatic compounds when compared to the hexane insoluble but toluene soluble resin fraction.

Illinois coal/RDF coprocessing to produce high quality solids and liquids; [Quarterly] technical report, September 1--November 30, 1993  

DOE Green Energy (OSTI)

It is the aim of this study to provide information pertinent to the development of a coal/RDF pyrolysis process capable of economically creating valuable products from high sulfur Illinois coal. This project will be carried out in a systematic manner. First, samples will be properly selected prepared, preserved and characterized. Then coals, various plastics, cellulose, and a high quality RDF will be pyrolyzed, steam pyrolyzed, hydro-pyrolyzed, and liquefied at various conditions. Next, blends of coal with various RDF components will be reacted under the same conditions. From this work synergistic effects will be identified and process parametric studies will be conducted on the appropriate mixtures and single components. Product quality and mass balances will be obtained on systems showing promise. Preliminary pyrolysis work will be conducted on a TGA. A Perkin Elmer TGA-7 Thermogravimetric Analyzer was employed to study pyrolysis. Significant interactions have been observed. Very preliminary microreactor experiments have been performed and the acquisition of some products for analysis has been achieved. Although, these results are preliminary they are also very encouraging.

Rheological properties essential for the atomization of coal water slurries (CWS). Quarterly progress report, March 15, 1995--June 15, 1995  

SciTech Connect

The analysis of pipeline transportation of highly concentrated suspensions such as coal-water slurries, can exhibit several flow characteristics depending on the concentration and the physical parameters of the dispersed phase. Experiments were conducted for coal-water slurries flows in a series of horizontal capillary tubes of diameters 0.8, 1.5 and 3.0 mm and 100 mm in length, in order to investigate the effect of concentration, pressure drop, and the transitional Reynolds number from laminar to turbulent flow in a homogeneous slurry. The solid concentration was varied from 15% to 63% in 0.1% xanthum gum solution. Pressure drop and the volume flow measurement were made using HVA-6 Capillary viscometer. The Reynolds numbers obtained were found to be dependent on the slurry concentration and the viscosity of the slurry mixture, but independent of the capillary diameter.

High Temperature Electrochemical Polishing of H(2)S from Coal Gasification. Quarterly progress report, April 1-June 30, 1997  

DOE Green Energy (OSTI)

An advanced process for the separation of hydrogen sulfide from coal gasification streams through an electrochemical membrane is being perfected. H{sub 2}S is removed from a synthetic gas stream, split into hydrogen, which enriches the exiting syngas, and sulfur, which is condensed downstream from an inert sweep gas stream. The process allows for continuous removal of H{sub 2}S without cooling the gas stream while allowing negligible pressure loss through the separator. Moreover, the process is economically attractive due to the elimination of the need for a Claus process for sulfur recovery. To this extent the project presents a novel concept for improving utilization of coal for more efficient power generation.

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. The report documents the development of a diffusion controlled heterogeneous condensation model and channel heat loss model for incorporation into the PACKAGE code used to calculate core flow plasma properties and generator efficiency. PACKAGE calculations comparing realistic baseload subsonic and supersonic generator models are also presented. Progress on the refinement of a laboratory scale coal combustion plasma source and its associated molecular beam mass spectrometer diagnostic and diode laser absorption plasma temperature measurement systems is documented. Finally, progress on the development of a numerical model describing arc behavior in MHD electrode boundary layers is presented.

Rheological properties essential for the atomization of Coal Water Slurries (CWS). Quarterly progress report, September 15, 1994--December 15, 1994  

SciTech Connect

The overall objective of this project is to perform experiments to understand the effect of high shear and extensional properties on the atomization of coal-water slurries (CWS). In the atomization studies, the mean drop size of the CWS sprays will be determined at various air-to-CWS. A correlation between the extensional and high shear properties, particle size distributions and the atomization will be made in order to determine the influence of these parameters on the atomization of CWS.

Development of alcohol-based synthetic transportation fuels from coal-derived synthesis gases. First quarterly progress report, September 14-December 31, 1979  

DOE Green Energy (OSTI)

Chem Systems is carrying out an experimental program for the conversion of coal-derived synthesis gases to a mixture of C/sub 1/-C/sub 4/ alcohols. The objectives of this contract are to: (1) develop a catalyst and reactor system for producing a mixture of C/sub 1/-C/sub 4/ alcohols, which we call Alkanol fuel, to be used as a synthetic transportation fuel and (2) assess the technical and economic feasibility of scaling the process concept to a commercial-scale application. Some of the accomplishments made this quarter were: (1) a small (75cc) fixed-bed, plug-flow, vapor phase reaction system was set up and operated utilizing catalyst bed dilution with inert media to help limit the large exotherm associated with the synthesis gas conversion reactions; (2) a total of fifteen (15) catalysts containing varying amounts of Cu, Co, Zn, Cr and K were prepared and seven of these catalysts were tested; (3) we have identified at least one promising catalyst composition which has resulted in a 30% conversion of carbon monoxide per pass (synthesis gas had a 3.5 H/sub 2//CO ratio) with a carbon selectivity to alcohols of about 80%.

Development and testing of industrial scale, coal-fired combustion system, Phase 3. Seventeenth quarterly technical progress report, January 1, 1996--March 31, 1996  

SciTech Connect

In the first quarter of calendar year 1996, 9 days of combust-boiler tests were performed. Between these tests, modifications and improvements that were indicated by these tests were implemented. In January and early February, the modifications and installations indicated by the 6 days of testing in December 1995 were implemented. This was followed by 6 additional consecutive test days in mid- February. This was in turn followed by additional modifications, followed by a series of 3 one day, coal fired tests at end of March. These latter tests were the first ones in which slagging conditions were achieved in the combustor. The maximum thermal input was 13 MMBtu/hr, which equals two-thirds of the rated boiler heat input. The measured thermal, combustion, and slagging performance achieved in the combustor was superior to that achieved in the final series of tests conducted in Williamsport in 1993. The combustor-boiler facility is now ready for implementation of the task 5 site demonstration.

Production of carbon molecular sieves from Illinois coal. [Quarterly] technical report, March 1, 1993--May 31, 1993  

DOE Green Energy (OSTI)

Carbon molecular sieves (CMS) have become an increasingly important class of adsorbents for use in gas separation and recover processes. The overall objective of this project is to determine whether Illinois Basin coals are suitable feedstocks for the production of CMS and to evaluate the potential application of these products in commercial gas separation processes. In Phase I of this project, gram quantities of char were prepared from Illinois coal in a fixed-bed reactor under a wide range of pyrolysis and activation conditions. Chars having surface areas of 1500--2100 m{sup 2}/g were produced by chemical activation using potassium hydroxide (KOH) as the activant. These high surface area chars had more than twice the adsorption capacity of commercial molecular sieves. The kinetics of adsorption of various gases, e.g., N{sub 2}, O{sub 2}, CO{sub 2}, CH{sub 4}, CO and H{sub 2}, on these chars at 25{degrees}C was determined. Several chars showed good potential for efficient O{sub 2}/N{sub 2}, CO{sub 2}/CH{sub 4} and CH{sub 4}/H{sub 2} separation; both a high adsorption capacity and selectivity were achieved. The full potential of these materials in commercial gas separations has yet to be realized. In Phase II of this project, larger quantities of char are being prepared from Illinois coal in a batch fluidized-bed reactor and in a continuous rotary tube kiln.

A comparison study of column flotation technologies for cleaning Illinois coal. [Quarterly] technical report, December 1, 1993--February 28, 1994  

Science Conference Proceedings (OSTI)

The objectives of this research project are to optimize the performance of six commercially available column technologies for the treatment of Illinois Basin coal fines and to compare their performance on the basis of the recovery-grade curve and column throughput capacity. A statistically-designed, experimental program will be conducted to optimize the critical operating performance values of each flotation column. During the previous reporting period, construction and installation of the six flotation columns were completed. The flotation feed sample that will be used for the tests in this investigation was collected from a coal preparation plant treating the Illinois No. 5 seam coal. During this reporting period, the flotation feed sample was characterized on a size-by-size basis for its ash, total sulfur, and BTU content. A release analysis was also conducted to obtain the best possible recovery versus product grade curve that can be achieved by a froth flotation process for the treatment of the Illinois No. 5 flotation feed sample. Experiments were initiated on the Jameson Cell. The preliminary results indicate that the Jameson Cell achieves a separation performance that is close to the release data. The experimental program on the Jameson Cell and the other flotation technologies will be performed during the next reporting period.

Refining and end use study of coal liquids. Second quarter 1995 technical progress report, April--June 1995  

Science Conference Proceedings (OSTI)

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.

Synthesis of acrylates and methacrlyates from coal-derived syngas. Quarterly technical progress report, January 1, 1995--March 31, 1995  

DOE Green Energy (OSTI)

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.

The use of solid-state NMR techniques for the analysis of water in coal and the effect of different coal drying techniques on the structure and reactivity of coal. Quarterly report, June 1, 1992--August 31, 1992  

SciTech Connect

The results of measuring the change in moisture content of the Eagle Butte and Usebelli coals as a function of time are shown in Figure 1. As expected, the measured moisture content increases with time and reaches a maximum after about 8 hours. Two different types of sorbed water are removed sequentially. Free or surface sorbed water is rapidly removed followed by the water in the micropores of the coal as the reagents migrate into the pore structure. There appears to be an induction period of about 4 hours for the Eagle Butte coal before the moisture content increases more rapidly with time due to the reactions of the more ``tightly bound or ``pore`` water with the reagents. The chemical drying experiment was repeated twice for the Usebelli coal. In the first experiment, aliquots of the reaction mixture were removed sequentially, and in the second experiment separate coal samples were prepared and allowed to stand until the appropriate time for the NMR spectrum to be acquired. Excellent reproducibility was obtained. Both cools were thermally dried by heating to 110{degrees}C for 1 hour. The moisture content was determined by weight loss. Using the thermal drying method, the Eagle Butte coal had a moisture content of 16.6 wt % and the Usebelli coal a moisture content of 14.1 wt %. These values are near the moisture content of coal as determined by chemical drying.

Engineering development of advanced coal-fired low emission boil systems. Quarterly technical progress report, October 1993--December 1993  

Science Conference Proceedings (OSTI)

The first test run of the Toroidal Vortex Combustor (TVC) was completed on December 6. Riley was unable to witness or set up independent sampling equipment for NO{sub x} and precursor measurement for this run. A second run which we witnessed, but did not sample, was completed December 17. This was conducted almost entirely near SR = 1.0 while Textron investigated temperature-load relationships to address concerns from Run 1. A third run was completed over the December holiday break on Dorchester coal to address concerns Textron had about the Illinois test coal. All subsequent tests will use the Illinois coal. Boiler, firing system design. Elevation drawings were developed for dry wall-fired, conventional U-fired slagging, and TVC fired slagging units. We are investigating the feasibility of modifying a conventional U-fired design for low-NOx operation as an alternative to the TVC. The approach taken to I date for NOx reduction in existing U-fired units is to retrofit with delayed-mixing burners with staging air at various places, similar to the approach with dry fired units. The concept of staged fuel addition or reburning for the U-fired system is being examined as a potential combustion NOx control approach. This concept has high potential due to the high temperature and long residence time available in the stagger. Some field trials with coke oven gas reburn produced very low NOx results. Modeling of this concept was identified as a priority task. The model development will include matching field data for air staging on slagging units to the predictions. Emissions control. Selection of an SO2 control process continues to be a high priority task. Sargent & Lundy completed a cost comparison of several regenerable processes, most of which have NOx control potential as well: Active coke, NOXSO, copper oxide, SNOX, ammonia (for SO only, ammonium sulfate byproduct), and a limestone scrubber for comparison.

Effect of coal beneficiation process on rheology/atomization of coal water slurries. Quarterly progress report, November 1, 1993--January 31, 1994  

SciTech Connect

The atomization study began with simulated fluids-(Mixtures of glycerine-water mixtures or corn syrup-water mixtures). This was done to minimize the experimental variables, optimize the experimental conditions for subsequent CWS atomization studies and also, simplify the analysis. The atomization data obtained for the simulated fluids are as shown in Table 1 and 2. The Air/Fuel ratio was varied from 0.12--0.40 in this study. variation of SMD as a Function of Viscosity. The SMD of glycerine-water mixtures at high Air/Fuel and low Air/Fuel data are plotted in Figures 5 and 6. The data show that at high Air/Fuel ratio, there is no significant change of the SMD as the viscosity is varied. However, at low Air/Fuel ratio the SMD shows a strong dependence on the viscosity. This is due to the fact that entrainment losses become more severe as A/F increases, In the high A/F regime, there is very little variation between the SMD and the viscosity of the glycerine-water solutions. This is probably due to the fact that the relative velocity between the droplets and the air is very high and this produces high pressure forces on the droplets to the same extent. Considerable dispersion of the droplets was also observed at high A/F ratios. This effect is minimized in the low A/F regime. Figures 5--8 show plots os SMD as a Function of Air/Fuel ratio. The plot show a linear dependence of SMD on the air to Fuel ratio. A fit of the experimental data to equation 1 in order to determine the necessary coefficients will be reported during the next quarter.

Advanced turbine design for coal-fueled engines. Quarterly technical report, [July 1, 1989--September 30, 1989  

SciTech Connect

Coal-fueled gas turbines require the development of a number of new technologies which are being identified by METC and its Heat Engines Contractors. Three significant problems, that were Identified early in the development of coal-fueled engines, are the rapid wear of the turbine airfoils due to particulate erosion, the accumulation of deposits on portions of the airfoil surfaces due to slag deposition and the rapid corrosion of airfoils after the breakdown of surface coatings. The technology development study contained in this program is focused on improving the durability of the turbine through the development of erosion and deposition resistant airfoils and turbine operating conditions. The baseline turbine meanline design vas modified to prevent a local shock on the suction side of the rotor airfoil. New particle dimensionless parameters to be varied were determined. Three first-stage turbine meanline designs have been completed. The design of nev turbine airfoil shapes has been initiated. The calculation of particle trajectories has been completed for the baseline turbine vane and blade airfoils. The erosion model described in the previous technical report vas incorporated in the Post Processing Trajectory Analysis Code.

Coal desulfurization in a rotary kiln combustor. Quarterly report No. 1, April 16, 1990--July 15, 1990  

Science Conference Proceedings (OSTI)

BCR National Laboratory (BCRNL) has initiated a project aimed at evaluating the technical and economic feasibility of using a rotary kiln, suitably modified, to burn Pennsylvania anthracite wastes, co-fired with high-sulfur bituminous coal. Limestone will be injected into the kiln for sulfur control, to determine whether high sulfur capture levels can be achieved with high sorbent utilization. The principal objectives of this work are: (1) to prove the feasibility of burning anthracite refuse, with co-firing of high-sulfur bituminous coal and with limestone injection for sulfur emissions control, in a rotary kiln fitted with a Universal Energy International (UEI) air injector system; (2) to determine the emissions levels of SO{sub x} and NO{sub x} and specifically to identify the Ca/S ratios that are required to meet New Source Performance Standards; (3) to evaluate the technical and economic merits of a commercial rotary kiln combustor in comparison to fluidized bed combustors; and, (4) to ascertain the need for further work, including additional combustion tests, prior to commercial application, and to recommend accordingly a detailed program towards this end.

Development of alternative fuels from coal-derived syngas. Quarterly status report No. 6, January 1--March 31, 1992  

SciTech Connect

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.

Chemistry and structure of coal-derived asphaltenes, Phase III. Quarterly progress report, January--March 1978  

SciTech Connect

The solubility limits of Synthoil and PAMCO asphaltenes have been measured as a function of Hildebrand solubility parameters and hydrogen bonding. Solvents with moderate hydrogen bonding capacity such as dioxane, ethyl benzoate and dibutyl phthalate were found to be most effective in dissolving asphaltenes over the widest range of solubility parameters. VPO molecular weight studies of coal liquid derived carbenes, as a function of concentration in the solvent THF, indicate that these fractions are more strongly self-associated than the corresponding asphaltenes, and generally afford high infinite dilution number average molecular weights: Synthoil, 861; HRI H-Coal, 1156; Cat. Inc. SRC, 1228; PAMCO SRC, 1054. The variable ESR temperature dependence of the spin intensity for a Synthoil asphaltene-I/sub 2/ charge transfer followed a 1/T (Curie--Weiss) dependence over the temperature range from 25/sup 0/ to -114/sup 0/C suggesting that independent, non-interacting donor and acceptor doublets were formed. Weight percent OH values, determined from 'H NMR analysis of silylated asphaltenes, were found to provide a reasonably linear correlation with the absorbance of the monomeric OH infrared stretching bands of the asphaltenes.

Chemistry and structure of coal-derived asphaltenes, Phase II. Quarterly progress report, January--March 1977. [15 refs  

SciTech Connect

Separations of Synthoil liquefied coal by solvent fractionation and high pressure liquid chromatography have been compared. Solvent fractionation is believed to give more distinctive fractions. The asphaltene fraction obtained by use of hplc was found to be a mixture of resin, asphaltene, carbene, and carboid. Solvent elution chromatrogrphy of asphaltenes on silica gel has been scaled up, and recoveries of 98-99 wt. % are generally obtained. VPO molecular weight studies of coal asphaltenes, as a function of concentration, in the solvents benzene and THF indicate that association of asphaltenes takes place in both solvents, but is more significant in benzene. Structural parameters obtained from modified Brown-Ladner treatment of proton NMR data suggest that solvent fractions: oil, resin, asphaltene, and carboid have structural characteristics which are sequentially related. X-ray diffraction patterns for asphaltene, carbene, and carboid fractions reveal progressively sharpened (002) and (11) bands indicative of increasing carbonization in this series. Methyl iodide addition to a basic fraction of Synthoil asphaltene (diethyl ether-eluted from silica gel) suggests, in conjunction with infrared results, that essentially all of the nitrogen in this fraction is present in basic pyridine-like compounds.

Slag characterization and removal using pulse detonation for coal gasification. Quarterly research report, October--December, 1995  

SciTech Connect

Experiments will mainly focus on breaking the bonds within the slag itself using detonation wave. For the experiments, initial suggestion was to build up slag deposit around a representative tube by placing it inside the convection pass of an actual boiler at the Northern States Power Company. But it was later concluded that once the tube is cooled to room condition, the thermal stress will greatly reduce the bonding between the heat transfer surface and the slag. It was concluded that the slag will be attached to the tube using high density epoxy resin. High density epoxy will be used so that they do not diffuse into the slag and strengthen the bonding within the slag. Suggestions on candidate epoxy are provided by MTI lab. MTI also provided PVAMU with different kinds of slags for testing. The deposits for characterization were from a subbituminous coal fired utility boiler.

Refining and upgrading of synfuels from coal and oil shales by advanced catalytic processes. Quarterly report, July--September 1977  

DOE Green Energy (OSTI)

The objective of this program is to determine the feasibility and estimate the economics of hydropreocessing four synthetic fuels to distillate fuels, including high octane gasoline, using presently available technology. The feedstocks include shale oil and three coal-derived synthetic crudes. The first feedstock is Paraho crude shale oil, produced in the indirectly heated mode. Pilot plant studies of hydrofining of whole shale oil with ICR 106 catalyst have been completed. The product resembles the fraction of a waxy petroleum crude boiling below 1000/sup 0/F. There is no 1100/sup 0/F+ residuum. A 3500-hour pilot plant run showed that the catalyst fouling rate is low and demonstrated that a commercial length run is feasible. However, a guard bed is necessary ahead of the catalyst bed to remove arsenic and iron which can cause plugging. Hydrofined shale oil is an excellent feed for a catalytic cracker. Pilot plant studies show that the 650/sup 0/F+ fraction of hydrofined shale oil is very similar to hydrofined Middle Eastern vacuum gas oils in its performance in a catalytic cracker. Process design studies based on pilot plant results indicate that it is desirable to hydrofine the whole shale oil to a nitrogen content of about 500 ppM and then to fractionate the product before conventional downstream processing to produce transportation fuels. An alternate scheme for shale oil processing is the coking of the shale oil followed by hydrofinishing of the coker distillate. Preliminary results appear promising. The second feedstock is solvent refined coal. Studies of the hydrofining of a 50/50 blend of SRC and creosote were continued. A run of 1100 hours was achieved with ICR 106 catalyst without the plugging problem that had plagued an earlier test. The catalyst deactivated at a relatively rapid rate.

Stabilization and/or regeneration of spent sorbents from coal gasification. [Quarterly] technical report, March 1, 1992--May 31, 1992  

Science Conference Proceedings (OSTI)

The objective of this investigation is to determine the effects of SO{sub 2} partial pressure and reaction temperature on the conversion of sulfide containing solid wastes from coal gasifiers to stable and environmentally acceptable calcium sulfate, while preventing the release of sulfur dioxide through undesirable side reactions during the stabilization step. An additional objective of this program is to investigate the use of the Spent Sorbent Regeneration Process (SSRP) to regenerate spent limestone, from a fluidized-bed gasifier with in-bed sulfur capture, for recycling to the gasifier. To achieve these objectives, selected samples of partially sulfided sorbents will be reacted with oxygen at a variety of operating conditions under sufficient S0{sub 2} partial pressure to prevent release of sulfur from the solids during stabilization that reduces the overall sorbent utilization. Partially sulfided limestone will also be regenerated with water using the SSRP to produce calcium hydroxide and release sulfur as H{sub 2}S. The regenerated sorbent will be dewatered, dried and pelletized. The reactivity of the regenerated sorbent toward H{sub 2}S will also be determined.

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. 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. After review DOE-METC approved funding in the amount of $1,246,019 to be available August 1, 1995. This report describes each task of the project and its status.

Whole shale oil was hydrofined in a 2000-hour pilot plant test using ICR 106 catalyst. The results show that shale oil containing 2.2 percent nitrogen can be hydrofined to residuum-free product containing 1 to 2 ppM nitrogen in a single stage. Process design studies indicate that it is preferable to hydrofine the whole shale oil to about 500 ppM nitrogen and then to fractionate the product before conventional downstream processing to produce transportation fuels. The product resembles the fraction of a waxy petroleum crude boiling below 1000/sup 0/F. This report includes yields and product properties determined from the small-scale pilot plant test. A larger-scale pilot plant demonstration run is now in progress.

Pyrite surface characterization and control for advanced fine coal desulfurization technologies. Seventh quarterly technical progress report, March 1, 1992--May 31, 1992  

SciTech Connect

The objective of this project is to conduct extensive studies on the surface reactivity and surface hydrophobicity of coal-pyrites using various surface characterization techniques and to correlate the alteration of the coal-pyrite surface with the efficiency of pyrite rejection in coal flotation. The flotation characteristics of coal-pyrites under various conditions was studied and compared with ore-pyrite and coal to determine the causes of pyrite rejection difficulties in coal flotation. Both the native and induced floatabilities of pyrites were investigated. It was found that both coal- and ore-pyrites, ff prepared by dry-grinding, show little or no floatability in the absence of any chemical reagents. After ultrasonic pretreatment, ore-pyrite floats effectively in the acidic to neutral pH range. Kentucky No. 9 coal-pyrite (KYPY) shows significant flotation in the pH range 7--10. With ethyl xanthate as collector, ore-pyrite floats well up to pH = 10; while coal-pyrite reveals no flotation above pH = 6. For the first time, the effect of coal collector on the floatability of coal-pyrite has been studied. It was shown that in the presence of fuel oil--a widely used collector for promoting coal flotation, coal-pyrite, particularly for the fine sizes, shows good flotation below pH = 11, whereas ore-pyrite has no or little floatability. These studies demonstrate that one of the main causes of the coal-pyrite flotation in coal separation is the oil-induced floatability due to adsorption/attachment of oil droplets on the coal-pyrite surfaces, the ``native`` or ``self-induced`` floatability of pyrite is no as profound as the oil-induced flotation.

Improvement of storage, handling, and transportability of fine coal. Quarterly technical progress report No. 7, July 1, 1995--September 30, 1995  

SciTech Connect

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 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. The Mulled Coal circuit was installed in an empty bay at the Chetopa Preparation Plant. Equipment has been installed to divert a 2.7 tonnes/hr (3 tons/hr) slipstream of the froth concentrate to a dewatering centrifuge. The concentrated wet coal fines from the centrifuge dropped through a chute directly into a surge hopper and feed system for the Mulled Coal circuit. The Mulled Coal product was gravity discharged from the circuit to a truck or product discharge area from which it will be hauled to a stockpile located at the edge of the clean coal stockpile area. During the 3-month operating period, the facility produced 870 tonnes (966 tons) of the Muffed Coal for evaluation in various storage, handling, and transportation equipment and operations. Immediately following the production demonstration, the circuit was disassembled and the facility was decommissioned.

HYDRAULIC CONDUCTIVITY OF SALTSTONE FORMULATED USING 1Q11, 2Q11 AND 3Q11 TANK 50 SLURRY SAMPLES  

SciTech Connect

As part of the Saltstone formulation work requested by Waste Solidification Engineering (WSE), Savannah River National Laboratory (SRNL) was tasked with preparing Saltstone samples for fresh property analysis and hydraulic conductivity measurements using actual Tank 50 salt solution rather than simulated salt solution. Samples of low level waste salt solution collected from Tank 50H during the first, second, and third quarters of 2011 were used to formulate the Saltstone samples. The salt solution was mixed with premix (45 wt % slag, 45 wt % fly ash, and 10 wt % cement), in a ratio consistent with facility operating conditions during the quarter of interest. The fresh properties (gel, set, bleed) of each mix were evaluated and compared to the recommended acceptance criteria for the Saltstone Production Facility. ASTM D5084-03, Method C was used to measure the hydraulic conductivity of the Saltstone samples. The hydraulic conductivity of Saltstone samples prepared from 1Q11 and 2Q11 samples of Tank 50H is 4.2E-9 cm/sec and 2.6E-9 cm/sec, respectively. Two additional 2Q11 and one 3Q11 sample were not successfully tested due to the inability to achieve stable readings during saturation and testing. The hydraulic conductivity of the samples made from Tank 50H salt solution compare well to samples prepared with simulated salt solution and cured under similar conditions (1.4E-9 - 4.9E-8 cm/sec).

During this reporting period, the influence of the impurity content, particularly coal/carbon content, on the electrochemical oxidation of pyrite surfaces was investigated. The studies demonstrate that the coal/carbon content in coal-pyrite has a determining effect on the surface reactivity of pyrite. The oxidation behavior of high carbon-content coal-pyrite is completely different from that of purer coal-pyrite and ore-pyrite. The effects of flotation gases on the flotation behavior of coal and the surface hydrophobicity of various coal-pyrite were investigated. It was found from the lab-scale column flotation studies that among the various gases studied (air, oxygen, argon, nitrogen and carbon dioxide), carbon dioxide produced the best results with a combustible recovery of 90% and ash-content of less than 9 percent. Finally, the surface energetic studies revealed that the surfaces of pyrites and coals produced by wet grinding is more heterogenous than that prepared by dry grinding.

Correlation of stability/rheology relationship with coal properties and chemical additives. Quarterly progress report, March 15, 1989--June 15, 1989  

SciTech Connect

Coal-water slurry (CWS) is being considered as a near term replacement for oil in both industrial and utility applications. Selecting an economical, yet technically compatible feedstock for producing highly loaded CWS is important to the commercialization of CWS technology (1) Previous work has shown that the dispersing additives can represent a significant portion of CWS preparation cost (2). In an effort to establish a criteria for designing and preparing CWS for utilization, the relationships between coal properties and slurry quality must be determined. These relationships will enable the prediction of potential CWS quality for the particular coal candidate from some characteristic(s) of the coal. The coal content at a given viscosity varies for different coal(3). Thus, to develop a viable coal selection strategy using chemical surfactants as additives, the adsorption of these surfactants by the coal particle surface must be established. This work therefore, intends to screen a number of chemical surfactants and dispersants which can be used in the preparation of coal water slurry. The information derived from this screening together with the coal properties will be used to help develop a prescription to predict the stability of coal slurries.

Removal of pyrite and trace elements from waste coal by dissolved-CO{sub 2} flotation and chelating agents. [Quarterly] technical report, December 1, 1993--February 28, 1994  

SciTech Connect

In dissolved-CO{sub 2} flotation, ultrafine -bubbles are generated by CO{sub 2} dissolved in water. The ultrafine bubbles have the potential to improve the separation efficiency in fine coal cleaning. Chemicals will be used prior to or during dissolved-CO{sub 2} flotation to improve the separation efficiency-CO{sub 2} of pyrite and other minerals including trace metals from coal. Chelating agent will be applied to clean coal to further reduce the trace metals from coal. During this period, a 3 in. diameter packed column has been purchased and installed. This column was then modified for use in dissolved-CO{sub 2} flotation. Coal samples of Illinois No. 6 coal are being prepared for flotation. Preliminary flotation tests were performed on Illinois No. 6 waste coal.

A novel approach to highly dispersing catalytic materials in coal for gasification. First quarterly report, October 1, 1989--December 31, 1989  

SciTech Connect

This project seeks to develop a technique, based on coal surface properties, for highly dispersing catalysts in coal for gasification and to investigate the potential of using potassium carbonate and calcium acetate mixtures as catalysts for coal gasification. The lower cost and high catalytic activity of the latter compound will produce economic benefits by reducing the amount of K{sub 2}CO{sub 3} required for high coal char reactivities. The work is focused on the elucidation of coal-catalyst precursor interactions in solution and the variables which control the adsorption and dispersion of coal gasification metal catalysts. In order to optimize coal-metal ion interactions and hence maximize catalyst activity, the study examines the surface electrochemistry of a lignite, a subbituminous, and a bituminous coals and their demineralized and oxidized derivatives prior to loading with the catalytic materials. The surface electrical properties of the coals are investigated with the aid of electrophoresis, while the effects of the surface charge on the adsorption of K{sup +} and Ca{sup 2+} are studied by agitating the coals with aqueous solutions of potassium and calcium. A zeta meter, a tube furnace, and other equipment required for the investigation have been acquired and installed. Preliminary work shows that the lignite (Psoc 1482) is negatively charged between pH 1.8 and pH 11.0 and has an isoelectric point of pH 1.8.

Engineering development of advanced physical fine coal cleaning technologies - froth flotation. Quarterly technical progress report No. 24, July 1, 1994--September 30, 1994  

SciTech Connect

A study conducted by Pittsburgh Energy Technology Center of sulfur emissions from about 1,300 United States coal-fired utility boilers indicated that half of the emissions were the result of burning coals having greater than 1.2 pounds of SO{sub 2} per million BTU. This was mainly attributed to the high pyritic sulfur content of the boiler fuel. A significant reduction in SO{sub 2} emissions could be accomplished by removing the pyrite from the coals by advanced physical fine coal cleaning. An engineering development project was prepared to build upon the basic research effort conducted under a solicitation for research into Fine Coal Surface Control. The engineering development project is intended to use general plant design knowledge and conceptualize a plant to utilize advanced froth flotation technology to process coal and produce a product having maximum practical pyritic sulfur reduction consistent with maximum practical BTU recovery.

Suppression of fine ash formation in pulverized coal flames. Quarterly technical progress report No. 4, July 1, 1993--September 30, 1993  

Science Conference Proceedings (OSTI)

Laboratory work and studies of full-scale coal-fired boilers have identified two general mechanisms for ash production. The vast majority of the ash is formed from mineral matter that coalesces as the char burns, yielding particles that are normally larger than 0.5 {mu}m. The second major mechanism is the generation of a submicron aerosol through a vaporization/condensation mechanism. Previous work has shown that pulverized bituminous coals that were treated by coal cleaning (via froth flotation) or aerodynamic sizing exhibited altered aerosol emission characteristics. Specifically, the emissions of aerosol for the cleaned and sized coals increased by as much as one order of magnitude. The goals of the present progress are to: (1) perform measurements on carefully characterized coals to identify the means by which the coal treatment increases aerosol yields; (2) investigate means by which coal cleaning can be done in a way that will not increase aerosol yields; (3) identify whether this mechanism can be used to reduce aerosol yields from systems burning straight coal. This paper discusses model description and model formulation, and reports on the progress of furnace design and construction, and coal selection.

The production of ash particles from coal combustion limits it`s use as a fuel. On mechanism by which small ash particles are formed is the generation of submicron aerosols through a vaporization/condensation mechanism. Previous work has shown that coal cleaning can lead to increased emissions of aerosols. This research will investigate the means or aerosol formation in coals and the effects that various methods of coal cleaning have on aerosol production, and whether or not cleaning can be performed in a manner that will not lend itself to aerosol formation.

Pelletization of fine coals  

SciTech Connect

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

Development and testing of a high efficiency advanced coal combustor: Phase 3, industrial boiler retrofit. Quarterly technical progress report number 12, July 1, 1994--September 30, 1994  

SciTech Connect

The objective of this project is to retrofit the previously developed High Efficiency Advanced Coal Combustor (HEACC) to a standard gas/oil designed industrial boiler to assess the technical and economic viability of displacing premium fuels with microfine coal. During this reporting period, data reduction/evaluation and interpretation from the long term four hundred hours Proof-of-Concept System Test under Task 3 were completed. Cumulatively, a total of approximately 563 hours of coal testing was performed with 160 hrs on 100% coal and over 400 hours with co-firing coal and gas. The primary objectives of this testing were to: (1) obtain steady state operation consistently on 100% coal; (2) increase carbon conversion efficiency from 95% to the project goal of 98%; and (3) maintain NOx emissions at or below 0.6 lbs/MBtu. The following specific conclusions are based on results of coal-fired testing at Penn State and the initial economic evaluation of the HEACC system: a coal handling/preparation system can be designed to meet the technical requirements for retrofitting microfine coal combustion to a gas/oil-designed boiler; the boiler thermal performance requirements were met; the NOx emission target of was met; combustion efficiencies of 95% could be met on a daily average basis, somewhat below the target of 98%; the economic playback is very sensitive to fuel differential cost, unit size, and annual operating hours; continuous long term demonstration is needed to quantify ash effects and how to best handle ashes. The following modifications are recommended prior to the 1,000 hour demonstration phase testing: (1) coal feeding improvements--improved raw coal/storage and transport, installation of gravimetric feeder, and redesign/installation of surge bin bottom; (2) burner modification--minor modification to the tip of the existing HEACC burner to prevent change of flame shapes for no apparent reason.

A new model of coal-water interaction and relevance for dewatering. Quarterly technical progress report, 1 June--31 August, 1992  

SciTech Connect

This project is concerned with a basic scientific question concerning the properties of coal -- to what extent is the ability of coal to hold moisture a manifestation of the well-known ability of coal to swell, when exposed to good solvents? The question implies that the long-held belief that coal holds a significant portion of its moisture by classical capillary condensation processes, is possibly in error. This seems to be a very real possibility for low rank coals- i.e. lignites. To explore this hypothesis further requires an examination of the basic phenomena governing the swelling of coals in good solvents. This is the focus of the first part of this project. The possibility that coal holds a significant portion of its moisture by solvent swelling mechanisms leads to an interesting technical issue. It is well known that simple drying of low rank coals at minemouth is ineffective because the process is reversible, to a significant degree. The economic advantages of preshipment drying have however dictated a search for ``permanent`` drying procedures. These have been developed by largely empirical means, and involve mild pyrolytic treatments of the coals in oil, steam or liquid water itself The idea has always been to pyrolytically remove oxygen groups, which are assumed to be those that hold water most strongly by hydrogen bonding. The treatments have been designed to minimize tar formation and decrepitation of the particles, both highly undesirable. In relation to the present new hypothesis concerning water retention, it is likely that a sound approach to permanent drying would involve highly crosslinking the coal at mild drying conditions. The crosslinked coal could not swell sufficiently to hold much water. It is identifying processes to achieve this goal, that constitute the objective of the second phase of this work.

500 MW demonstration of advanced wall-fired combustion techniques for the reduction of nitrogen oxide (NO{sub x}) emissions from coal-fired boilers. Technical progress report, third quarter 1994, July 1994--September 1994  

Science Conference Proceedings (OSTI)

This quarterly report discusses the technical progress of an Innovative Clean Coal Technology (ICCT) demonstration of advanced wall-fired combustion techniques for the reduction of nitrogen oxide (NOx) emissions from coal-fired boilers. The project is 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 NOx combustion equipment through the collection and analysis of long-term emissions data. A target of achieving fifty percent NOx reduction using combustion modifications has been established for the project. The project provides a stepwise evaluation of the following NOx reduction technologies: Advanced overfire air (AOFA), Low NOx burners (LNB), LNB, with AOFA, and Advanced Digital Controls and Optimization Strategies. Baseline, AOFA, LNB, and LNB plus AOFA test segments have been completed. Based on a preliminary analysis, approximately 17 percent of the incremental change in NOx emissions between the LNB and LNB+AOFA configurations is the result of AOFA, the balance of the NOx reduction resulting from other operational adjustments. Preliminary diagnostic testing was conducted during August and September. The purpose of these tests was to determine the emissions and performance characteristics of the unit prior to activation of the advanced control/optimization strategies. Short-term, full load NOx emissions were near 0.47 lb/MBtu, slightly higher than that seen during the LNB+AOFA test phase. Long-term NO{sub x} emissions for this quarter averaged near 0.41 lb/MBtu. Due to turbine problems, a four week outage has been planned for Hammond 4 starting October 1. Two on-line carbon-in-ash monitors are being installed at Hammond Unit 4 as part of the Wall-Fired Project. These monitors will be evaluated as to their accuracy, repeatability, reliability, and serviceability.

Development and testing of a commercial scale coal-fired combustion system, Phase 3. Quarterly technical progress report No. 8, July 1, 1992--September 30, 1992  

SciTech Connect

This report summarizes the results of work performed in the development and proof-of-concept (POC) testing of a coal-fired space heating system for the commercial market sector. The objective of this program is to design, build and test a coal based heating system for this sector and determine the economic viability and market potential for the system. Coal water slurry (CWS) fuel has been chosen as the fuel form for this development effort. CWS eliminates the need to use dry pulverized coal with its attendant handling, metering and dusting problems as well as its explosive potential. Equally important in selecting a fuel form is the impact on emission levels and pollution control equipment requirements. CWS is amenable to coal washing since coal cleaning technologies are generally water-based processes requiring the fine grinding of the coal. In the first stage. an overall system heat balance was prepared, system components were designed and manufactured or purchased, the system was fully assembled and preliminary testing performed to validate component performance and identify key operating variables. In the second stage the system was operated for prolonged periods to simulate a commercial application, and combustion and thermal efficiencies; tendencies to slag, foul, erode and corrode; and gaseous and particulate emissions were evaluated. Also during the second stage, an assessment of the commercial viability of the system was made. This assessment included an evaluation of the economics and market potential, including the sensitivity to fluctuations in fuel prices.

Characteristics of American coals in relation to their conversion into clean energy fuels. Quarterly technical progress report, July--September 1975  

SciTech Connect

Twenty-one coal samples have been collected and characterized. Sixty coals have been provided to other agencies at their request. The capability of controlling coal characteristics during preparation is being developed: large variations in volatile content occur within a given raw coal but, by controlling the preparation, a uniform product with the devised specifications can be produced. Studies have begun on the suitability of various coals and cokes for use in pressurized fixed bed gasifiers. Preliminary studies are being carried out on the feasibility of applying small angle x-ray scattering to the characterization of coal chars. Reactivity profiles and parameters for chars in air are markedly dependent upon the gaseous flow system used, indicating that char reactivity is determined by partial pressure of the reacting gas. Reactivities have been maximized by keeping the heat treatment temperature as low as possible, and allowing no soak time. The minerals kaolinite, dolomite, siderite, calcite, and pyrite are found not to be catalysts for the char-air reaction at 550/sup 0/C. The addition of coal to an oil-water-air emulsion considerably increases the heat flux from the flame to the water tubes during combustion. (auth)

Organosulphur compounds in coals as determined by reaction with Raney nickel and microscale pyrolysis techniques. First quarterly report, July 1, 1994--September 30, 1994  

Science Conference Proceedings (OSTI)

This project is designed to study the nature of sulphur-containing organic compounds and their respective linkages in coals and related materials using a variety of microscale pyrolysis techniques combined with gas chromatography, gas chromatography -- mass spectrometry, and gas chromatography -- mass spectrometry/mass spectrometry. The majority of the work will be undertaken using a PYRAN pyrolysis system purchased with funds from the DOE University Instrumentation Program. Although significant studies in the past have examined hydrocarbons produced from the pyrolysis of coals, little attention has been directed at studying the heteroatomic components produced in this way. With the use of carefully controlled temperature-programmed pyrolysis reactions it should be possible to obtain information on the relative bond energies of the C-S and S-S bonds being cleaved during coal pyrolysis and to provide a better understanding on the nature of the sulphur bonding in coals. In the experiments performed with Raney nickel and coal, the results showed that while Raney nickel was indeed and excellent degrader of organic sulphur compounds in oils and coal extracts, the recovery from a high sulphur Oklahoman coal was negligible. Following the realization that Raney nickel is of little use in cleaving organosulphur compounds from coals, a new literature review was initiated to determine which possible sulphur chemical degradation method would be an appropriate replacement. After careful consideration of the various possible methods, it would appear that the procedure which will work on solid phases (i.e., coal), will give similar results to the Raney nickel method, and which we may be able to perform here with the least level of expenditure on new equipment, is the use of nickel(O)cene (bis[1,5-cyclopentadiene]nickel(O)) with lithium aluminum hydride (LiAlH{sub 4}).

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

Science Conference Proceedings (OSTI)

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

Enthalpy measurement of coal-derived liquids. Combined quarterly technical progress reports, April-June 1979 and July-September 1979. [Effect of association  

DOE Green Energy (OSTI)

Enthalpy measurements on a coal-derived naphtha and middle distillate, both produced by the SRC-II process, were made using flow calorimetry. The accuracy of the measurements, as reported by Omid, was within +- 1% of the measured enthalpy differences, ..delta..H. Experimental data for the naphtha were obtained over a pressure range of 100-300 psia and temperatures from 148/sup 0/ to 456/sup 0/F. The middle distillate enthalpy measurements were made in the pressure and temperature ranges of 130 to 1000 psia, and 157/sup 0/ to 675/sup 0/F, respectively. The methods of prediction of enthalpy developed for petroleum fractions were unsatisfactory when applied to the above data. A negative bias was observed in the predicted enthalpy values for several of the coal-liquids. Based on these results, it was theorized that the high experimental enthalpy values for coal-liquids were due to an energy of association attributed, primarily, to hydrogen-bonding effects. The petroleum-fraction enthalpy correlations were then tested on the experimental data for pure compounds, both associating and non-associating. The predicted values compared very well with the experimental results for non-associating model compounds. However, for associating model compounds the predicted enthalpy values were considerably lower than their experimental data. This served to confirm the basic premise that the high experimental enthalpy values, for model compounds and coal liquids, were a direct consequence of an energy of association attributed, primarily, to hydrogen-bonding effects.

Illinois coal/RDF coprocessing to produce high quality solids and liquids. [Quarterly] technical report, December 1, 1993--February 28, 1994  

DOE Green Energy (OSTI)

It is the aim of this study to provide information pertinent to the development of a coal/RDF pyrolysis process capable of economically creating valuable products from high sulfur Illinois coal. This project will be carried out in a systematic manner. First, samples will be properly selected prepared, preserved and characterized. Then coals, various plastics, cellulose, and a high quality RDF will be pyrolyzed, steam pyrolyzed, hydro-pyrolyzed, and liquefied at various conditions. Next, blends of coal with various RDF components will be reacted under the same conditions. From this work synergistic effects will be identified and process parametric studies will be conducted on the appropriate mixtures and single components. Product quality and mass balances will be obtained on systems showing promise. Preliminary pyrolysis work will be conducted on a TGA. Over 100 microreactor experiments have been performed and the acquisition of products for analysis has been achieved. Interactions occur between 400--450{degrees}C. The use of higher temperatures should be avoided if liquids are the.desired product. Although, these results are preliminary they are also very encouraging.

Engineering development of coal-fired high performance power systems, Phase 2 and 3. Quarterly progress report, October 1--December 31, 1995  

SciTech Connect

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 (HHV); NO{sub x}, SO{sub x} and particulates {ge} 10% NSPS; coal {ge} 65% of heat input; all solid wastes benign; and cost of electricity 90% of present plant. The HIPPS generating plant integrates a combustion gas turbine/HRSG combined cycle arrangement with an advanced coal-fired boiler. The unique feature of the HIPPS plant is the partial heating of gas turbine (GT) compressor outlet air using energy released by firing coal in the high temperature advanced furnace (HITAF). The compressed air is additionally heated prior to entering the GT expander section by burning natural gas. Energy available, in the gas turbine exhaust and in the HITAF flue gas are used in a steam cycle to maximize energy production. The HIPPS plant arrangement is thus a combination of existing technologies (gas turbine, heat recovery boilers, conventional steam cycle) and new technologies (the HITAF design especially the heater located in the radiant section). Work reported herein is from Task 1.3, HIPPS Commercial Design and Task 2.2, HITAF Air Heaters.

The economical production of alcohol fuels from coal-derived synthesis gas. Quarterly technical progress report Number 8, 1 July, 1993--30 September, 1993  

DOE Green Energy (OSTI)

Task 1, the preparation of catalyst materials, is proceeding actively. At WVU, catalysts based on Mo are being prepared using a variety of approaches to alter the oxidation state and environment of the Mo. At UCC and P, copper-based zinc chromite spinel catalysts will be prepared and tested. The modeling of the alcohol-synthesis reaction in a membrane reactor is proceeding actively. Under standard conditions, pressure drop in the membrane reactor has been shown to be negligible. In Task 2, base case designs had previously been completed with a Texaco gasifier. Now, similar designs have been completed using the Shell gasifier. A comparison of the payback periods or production cost of these plants shows significant differences among the base cases. However, a natural gas only design, prepared for comparison purposes, gives a lower payback period or production cost. Since the alcohol synthesis portion of the above processes is the same, the best way to make coal-derived higher alcohols more attractive economically than natural gas-derived higher alcohols is by making coal-derived syngas less expensive than natural gas-derived syngas. The maximum economically feasible capacity for a higher alcohol plant from coal-derived syngas appears to be 32 MM bbl/yr. This is based on consideration of regional coal supply in the eastern US, coal transportation, and regional product demand. The benefits of economics of scale are illustrated for the base case designs. A value for higher alcohol blends has been determined by appropriate combination of RVP, octane number, and oxygen content, using MTBE as a reference. This analysis suggests that the high RVP of methanol in combination with its higher water solubility make higher alcohols more valuable than methanol.

Characterization of open-cycle coal-fired MHD generators. Quarterly technical summary report No. 6, October 1--December 31, 1977. [PACKAGE code  

DOE Green Energy (OSTI)

Research has included theoretical modeling of important plasma chemical effects such as: conductivity reductions due to condensed slag/electron interactions; conductivity and generator efficiency reductions due to the formation of slag-related negative ion species; and the loss of alkali seed due to chemical combination with condensed slag. A summary of the major conclusions in each of these areas is presented. A major output of the modeling effort has been the development of an MHD plasma chemistry core flow model. This model has been formulated into a computer program designated the PACKAGE code (Plasma Analysis, Chemical Kinetics, And Generator Efficiency). The PACKAGE code is designed to calculate the effect of coal rank, ash percentage, ash composition, air preheat temperatures, equivalence ratio, and various generator channel parameters on the overall efficiency of open-cycle, coal-fired MHD generators. A complete description of the PACKAGE code and a preliminary version of the PACKAGE user's manual are included. A laboratory measurements program involving direct, mass spectrometric sampling of the positive and negative ions formed in a one atmosphere coal combustion plasma was also completed during the contract's initial phase. The relative ion concentrations formed in a plasma due to the methane augmented combustion of pulverized Montana Rosebud coal with potassium carbonate seed and preheated air are summarized. Positive ions measured include K/sup +/, KO/sup +/, Na/sup +/, Rb/sup +/, Cs/sup +/, and CsO/sup +/, while negative ions identified include PO/sub 3//sup -/, PO/sub 2//sup -/, BO/sub 2//sup -/, OH/sup -/, SH/sup -/, and probably HCrO/sub 3/, HMoO/sub 4//sup -/, and HWO/sub 3//sup -/. Comparison of the measurements with PACKAGE code predictions are presented. Preliminary design considerations for a mass spectrometric sampling probe capable of characterizing coal combustion plasmas from full scale combustors and flow trains are presented and discussed.

Characteristics of American coals in relation to their conversion into clean energy fuels. Quarterly technical progress report, April-June 1979  

SciTech Connect

The study is continuing into the effects of low temperature oxidation on reducing the agglomerating properties of caking coals. Increases in oxidation temperature are shown to increase the effectiveness of oxygen in destroying plastic properties. Controlled studies indicate that additions of small amounts of oxygen (1 to 2% by wt) bring about drastic reductions in swelling properties. Oxidation may be considered a surface pheneomenon and it is shown here that the plastic properties of oxodized coals are partially restored by grinding to expose new surface. Finally, water vapor is shown to have an enhancing effect on room-temperature oxidation of coal. In the same task, small angle x-ray scattering (SAXS) techniques are beng evaluated as a method for determining size distributions of heterogeneities in coal chars. To test the applicability of the procedures, SAXS data have been generated from a well characterized glassy carbon (Tokai GC-30) and Saran chars prepared at different heat treatment temperatures (1100, 1300, 1500/sup 0/C). Results indicate that these approaches hold much promise for characterizing the porous structure of microporous carbons. Experimental conditions for Saran char burn-off have been chosen. Burn-off plots for two different particle sizes using the gas chromatograph tube furnace system have been constructed. The determination of the carboxyl group content of the three American lignites chosen has been completed. The results are included in this report. Also, the exchanged coal was back-exchanged with perchloric acid. The barium released was analyzed by emission spectrometry and compared to the value found by the original barium acetate treatment. The results show good agreement. Work was also undertaken to analyze the carboxylic salts.

500 MW demonstration of advanced wall-fired combustion techniques for the reduction of nitrogen oxide (NOx) emissions from coal-fired boilers. Technical progress report, fourth quarter, 1994, October 1994--December 1994  

Science Conference Proceedings (OSTI)

This quarterly report discusses the technical progress of an innovative Clean Coal Technology (ICCT) demonstration of advanced wall-fired combustion techniques for the reduction of nitrogen oxide (NOx) emissions from coal-fired boilers. The project is 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 NOx combustion equipment through the collection and analysis of long-term emissions data. The project provides a stepwise evaluation of the following NOx reduction technologies: Advanced overfire air (AOFA), Low NOx burners (LNB), LNB with AOFA, and Advanced Digital Controls and Optimization Strategies. The project has completed the baseline, AOFA, LNB, and LNB+AOFA test segments, fulfilling all testing originally proposed to DOE. Analysis of the LNB long-term data collected show the full load NOx emission levels to be near 0.65 lb/MBtu. This NOx level represents a 48 percent reduction when compared to the baseline, full load value of 1.24 lb/MBtu. These reductions were sustainable over the long-term test period and were consistent over the entire load range. Full load, fly ash LOI values in the LNB configuration were near 8 percent compared to 5 percent for baseline. Results from the LNB+AOFA phase indicate that full load NOx emissions are approximately 0.40 lb/MBtu with a corresponding fly ash LOI value of near 8 percent. Although this NOx level represents a 67 percent reduction from baseline levels, a substantial portion of the incremental change in NOx emissions between the LNB and LNB+AOFA configurations was the result of operational changes and not the result of the AOFA system.
