Title: Cooperative research in coal liquefaction infratechnology and generic technology development: Final report, October 1, 1985 to December 31, 1986

Abstract

During the first year of its research program, the Consortium for Fossil Fuel Liquefaction Science has made significant progress in many areas of coal liquefaction and coal structure research. Research topics for which substantial progress has been made include integrated coal structure and liquefaction studies, investigation of differential liquefaction processes, development and application of sophisticated techniques for structural analysis, computer analysis of multivariate data, biodesulfurization of coal, catalysis studies, co-processing of coal and crude oil, coal dissolution and extraction processes, coal depolymerization, determination of the liquefaction characteristics of many US coals for use in a liquefaction database, and completion of a retrospective technology assessment for direct coal liquefaction. These and related topics are discussed in considerably more detail in the remainder of this report. Individual projects are processed separately for the data base.

  • The purpose of this project is to support the development of generic technology and infratechnology research in support of liquefaction technology in cooperation with a research consortium, the Consortium for Fossil Fuel Liquefaction Science (CFFLS). The proposed research spans three activity areas, including generic technology research, infratechnology research, and support studies. A number of tasks have been undertaken in these activity areas by investigators at various research sites, and these research tasks will be coordinated by the project director at the University of Kentucky. Generic technology research consists of the following three tasks: (1) development of an improved coal structuremore » for better liquefaction; (2) co-processing of coal with heavy oils and petroleum residuals; and (3) liquefaction research in pyrolysis and coal dissolution. Infratechnology research consists of two tasks, integrated coal liquefaction/characterization, and basic process/resource evolution. Support studies include the task of technology assessment and forecasting. Progress reports are presented for these tasks.« less

    Research in the area of co-processing focused on the demetallization of crude oil by coal. It was demonstrated that other carbonaceous materials, such as activated carbon and char produced from cellulose, also demetallize the oil effectively. Co-processing was also demonstrated to be effective in desulfurization and denitrogenation. Processing coal/oil mixtures (coal:oil = 10:90 to 25:75) for one hour yielded sulfur and nitrogen removals of approximately 50% to the product gas and to the THF insolubles. Vitrinite concentrates were obtained from KY No. 9 and No. 11 coals by density gradient centrifugation. The concentrates, which were greater than 96% vitrinite, weremore » liquefied in microautoclaves at 385, 427, and 445/sup 0/C. The maximum conversions, greater than 96%, occurred at 427/sup 0/C. Liquefaction data have now been obtained for one hundred coals. To date, the best linear correlation with conversion is with total reactive maceral content of the coals. A Retrospective Technology Assessment (RTA) on Direct Coal Liquefaction (DCL) is near completion. Work in this quarter focused on analyzing the evolution of DCL and the failure to commercialize the technology to date. Interviews with a number of major DCL researchers have been and will continue to be conducted, in order to trace knowledge flows and identify knowledge gaps. An AT and T 3B20 computer at the University of Kentucky will be used to host the Consortium database. AT and T personal computers interfaced with the 3B20 will be used for development and management of the Consortium database/network.« less

    Progress reports are presented for the following tasks: (1) biologically improved coal structure for better liquefaction of coal, and (2) basic process/resource evaluation. Under task 1 experiments were conducted for: microbial desulfurization of high-sulfur coal by Sulfolobus brierleyi; optimization of pH for sulfur oxidation by Sulfolobus brierleyi; development and isolation of pure colonies of sulfolobus brierleyi, Thiobacillus ferroxidans and Thiobacillus thiooxidans; determination of protein concentration with Coomassie Blue and the modified Lowry's method in a 0.1N NaOH solution; and preparation and characterization of catalysts for coal liquefaction. For task 2, thirty-five coal samples have been collected from eastern Kentucky andmore » these have been prepared for analysis. 2 figs., 3 tabs.« less

The following projects are addressed: coal desulfurization by bioprocessing; materials characterization study of liquefaction processes; novel approaches to catalysis in coprocessing and in direct coal liquefaction; liquefaction research in pyrolysis catalysis, and coal dissolution; enhanced reactivity and selectivity in coal liquefaction and coprocessing systems.
