Hydrocarbon Research, Inc. (HRI) has completed the first one and one-half years of a two year study for the Department of Energy (DOE) under Contract No. DE-AC-22-85PC80002 for the development of a ''Low Severity Catalytic Liquefaction Process'' based on the (CTSL) Catalytic Two-Stage Liquefaction of coal. Distinct elements of the two-stage process are a lower temperature first stage and close coupling of two ebullated-bed reactor stages. This report covers the Illinois No. 6 coal portion of the program including experimental microreactor, microautoclave, and continuous bench unit studies from October 1985 through May 1987. The remaining portion of this contract was devoted to the study of Ohio coal. Results from continuous bench unit operations over a nineteen month period of studies on process variables, recycle, catalysts, variable volume and thermal effects, cleaned coals, and extinction recycle of heavy oils are analyzed, compared, and presented along with conclusions and recommendations. In the Illinois No. 6 coal program for this contract there were 15 bench runs with a total of 229 on-stream days with coal feed. A wide range of process variables, including temperature, residence time (coal space velocity), pressure, and recycle compositions were evaluated. Several catalysts with different physical and chemical properties were evaluated resulting in the selection of a new commercial catalyst for the demonstration phase. Product characterization studies by HRI and other DOE contractors, which support this program, are included. In addition, work on process modelling, equipment improvements and engineering analysis is included.
