Hydrocarbon Research, Inc. (HRI) has completed a series of studies for the evaluation of a ''New Technology Concept for Two-Stage Liquefaction of Coal''. The time period of studies covered May 26, 1983 to November 25, 1985, a total of thirty months, with the major effort devoted to Illinois No. 6 bituminous coal and the balance devoted to Wyodak sub-bituminous coal. A two-stage coal liquefaction process, based on two close-coupled catalytic ebullated-bed reactors with the first stage operating at low temperature for maximum hydrogenation, has been developed and demonstrated on Illinois No. 6 and Wyodak coals. This final report presents an executive summary of the program and completes the reporting requirements of Contract No. DE-AC22-83PC60017. A summary of the studies and process demonstrations is presented along with references to the Topical Reports on Illinois No. 6 coal, Wyodak coal, Conceptual Commercial Plant Design and Economics and reports by DOE sponsored support contractors. Experimental details are contained in the referenced reports. The accomplishments of this program and recommendations for a follow-on program are presented. By application of this new hydrogenation concept in this study, distillate yields of greater than 65 W % of M.A.F. Coal or 4.2 barrels per ton of M.A.F. coal were demonstrated on both Illinois No. 6 and Wyodak coals. This was accompanied by a ten-fold reduction in bottoms viscosity and the production of low sulfur environmentally clean fuels. As reported by Conoco, Inc. and Battelle Pacific Northwest Laboratories, a higher level of hydrogenation is evident and the liquids produced are more petroleum-like than coal liquids derived from other liquefaction processes. Upgrading studies on the Wyodak products are being performed by Chevron. 7 figs., 14 tabs.
