Book excerpt: 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°F, 1050°F, and 850 x 1050°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.

(CONSOL) is conducting a program to characterize process and product streams from direct coal liquefaction process development projects sponsored by the Department of Energy. In this program, CONSOL obtains samples from current process development activities in coal liquefaction and coal-oil coprocessing, and characterizes them using established analytical techniques. In addition, selected samples are characterized by other analytical techniques to evaluate their potential for aiding process development. These analyses and interpretation of the results in relation to process operations are provided by the subcontractor. Major topics reported in this fifteenth quarterly report are the following: (1) the status of the Participants Program is described, trips were made to The Pennsylvania State University and the University of Delaware for the purpose of establishing teaming arrangements, the trip reports are appended; (2) a description of work in progress in included, (3) two papers are appended. One of these papers describes work performed under subcontract in Phase 1 of the Participants Program by the University of Kentucky Center for Applied Energy Research. The second paper describes stable carbon isotope analysis of coprocessing materials. Both papers were accepted for publication in Fuel.

This book was released on 1997 with total page 50 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objectives of this project are to support the DOE direct coal liquefaction process development program and to improve the useful application of chemical analyses to direct coal liquefaction process development. Independent analyses by well-established methods are obtained of samples produced in direct coal liquefaction processes under evaluation by DOE. Additionally, new analytical instruments and techniques to examine coal-derived samples are being evaluated. The data obtained form this study are used to guide process development and to develop an improved data base on coal and coal liquids properties. A sample bank, established and maintained for use in this project, is available for use by other researchers. The reactivity of the non-distillable resids toward hydrocracking at liquefaction conditions (i.e., resid reactivity) is being examined. From the literature and experimental data, a kinetic model of resid conversion will be constructed. Such a model will provide insights to improve process performance and the economics of direct coal liquefaction.

Available in PDF, EPUB and Kindle. Book excerpt: This is the Technical Progress Report for the sixteenth quarter of activities under DOE Contract No. DE-AC22-94PC93054. It covers the period April 1 through June 30, 1998. Described in this report are the following activities: (1) CONSOL characterized nine process stream samples received from Exxon Recycle Coal Liquefaction Unit (RCLU) operations conducted in 1994 with Rawhide Mine Wyoming subbituminous coal and all-dispersed Fe and Mo catalysts. (2) The University of Delaware subcontract related to resid reactivity was completed with issuance of the Topical Report covering work performed by Delaware. (3) Computational studies of the coal liquefaction resid models developed at the University of Delaware were continued at CONSOL R and D. The two reaction models, consisting of the reaction optimization and reaction once-through programs, were the focus of these studies. The updated resid structure data and results were used in the reaction models to predict percent conversion values that were compared with the experimentally-measured values from the University of Delaware. (4) Small samples of high-sulfur Hondo resid and anthracene oil were shipped to John Verkade of Iowa State University at his request. Verkade is testing a desulfurization method.

Book excerpt: This is the Sixteenth Quarterly Technical Progress Report under DOE Contract DE-AC22-89PC89883. Major topics reported are: Fifty-eight process samples from HRI CTSL Bench Unit Run CC-15 (227-75) were analyzed to provide information on process performance. Run CC-15 was operated for 14 periods (days) from October 21 through November 3, 1992 in the thermal/catalytic configuration with Black Thunder Mine (Wyodak and Anderson seams) coal and Shell S-317 Ni/Mo supported extrudate catalyst. The run was made to test performance with and without a dispersed hydrous iron hydroxide catalyst precursor impregnated in the coal. Results are compared with those of previous HRI CTSL bench unit Run CC-1, which was operated in the catalytic/catalytic configuration, also with Shell S-317 catalyst. Several HRI Run CC-15 product distillate fractions prepared by the National Institute for Petroleum and Energy Research (NIPER) for petroleum inspection tests were further characterized by CONSOL. These characterization data are presented. MicroAutoclave tests and chemical analyses were performed to evaluate the solvent quality of two potential solvents for Alberta Research Council ARC. Eight product samples from catalytic dehydrogenation experiments were characterized for the University of Pittsburgh. A description is presented of the thermogravimetric analysis (TGA) method for determination of resid concentration/resid conversion, which was adapted for use in-house from HRI's standard method. A brief summary of the status of the Participants Program is given.

This book was released on 1992 with total page 129 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the tenth Quarterly Technical Progress Report under DOE Contract DE-AC22-89PC89883. Process oils from Wilsonville Run 262 were analyzed to provide information on process performance. Run 262 was operated from July 10 through September 30, 1991, in the thermal/catalytic Close-Coupled Integrated Two-Stage Liquefaction (CC-ITSL) configuration with ash recycle. The feed coal was Black Thunder Mine subbituminous coal. The high/low temperature sequence was used. Each reactor was operated at 50% of the available reactor volume. The interstage separator was in use throughout the run. The second-stage reactor was charged with aged Criterion 324 catalyst (Ni/Mo on 1/16 inch alumina extrudate support). Slurry catalysts and sulfiding agent were fed to the first-stage reactor. Molyvan L is an organometallic compound which contains 8.1% Mo, and is commercially available as an oil-soluble lubricant additive. It was used in Run 262 as a dispersed hydrogenation catalyst precursor, primarily to alleviate deposition problems which plagued past runs with Black Thunder coal. One test was made with little supported catalyst in the second stage. The role of phenolic groups in donor solvent properties was examined. In this study, four samples from direct liquefaction process oils were subjected to O-methylation of the phenolic groups, followed by chemical analysis and solvent quality testing.

This book was released on 2001 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: CONSOL completed characterization of 64 samples from five run conditions of HTI Run ALC-1 (227-94), in which raw and cleaned (oil-agglomerated at low pH) Black Thunder Mine subbituminous coal was fed and processed using only dispersed catalysts in the liquefaction reactors. Extraction of THF-soluble resid from the pressure-filter cakes was more complete when agglomerates were fed, leaving only 5% or less THF solubles in the extracted cakes. When raw coal was fed, the extracted cakes contained 9-34% THF solubles. HTI also observed improved filtration during the periods that agglomerates were fed. Improved operability, if verified by additional work, could be an economically significant benefit of coal cleaning by oil agglomeration at low pH. An apparently higher Mo addition rate (see fourth bullet) may have contributed to the benefits of using oil-agglomerated coal. Other stream sample characteristics changed when oil-agglomerated coal was fed in Conditions 2-4, relative to when uncleaned coal was fed in Conditions 1 and 5. The ash content of the 0-6 bottoms samples was lower when oil-agglomerates were fed. The THF-soluble 524[degrees]C+ resid concentration in the feed slurry doubled when agglomerated coal was fed. Three factors may have influenced these characteristics. Higher coal conversion would have produced more resid. More efficient toluene-extraction of the filter cake would have recycled more resid. Removal of distillate as product to offset oil fed as part of the agglomerated coal would preferentially recycle the heaviest components.
