In the hydrotreating processability study of Solvent Refined Coal (SRC) in addition to studying the effects of various variables, a preparative hydrotreating run was made to produce 4.5-gallons of upgraded SRC for use as feedstock in a hydrocracking study. This charge stock serves as the last of eight ERDA coal liquids to be characterized as to processability by conventional petroleum refining technology. The upgraded SRC, containing 9.8 percent C/sub 7/-insolubles and 70.1 percent 650/sup 0/F/sup +/ bottoms, was processed over a commercial hydrocracking catalyst at four sets of conditions, including a catalyst activity check at startup conditions at the conclusion of the run. At base space velocity, 10/sup 0/C above base temperature, and 200 psig above base pressure, conversion, defined as percentage disappearance of 650/sup 0/F/sup +/ bottoms, was only 11.8 percent. This low yield of 650/sup 0/F/sup -/ distillate is attributed to the presence of high molecular weight asphaltic materials.
