In a new version of the solvent refining process devloped by Pittsburg and Midway Coal Mining Co., a distillate fuel oil rather than a solid product is obtained by replacing the distillate solvent used as recycle oil by a coal-solvent slurry, i.e., the filtration step is eliminated. Under typical SRC II conditions, i.e., 465/sup 0/C, 2000 psi hydrogen, 1.0 hr residence time, and 35% coal in the feed slurry, yields were 12.2% C/sub 1/-C/sub 4/ hydrocarbons, 19.5% light oil, 24.8% heavy distillate (bp 249/sup 0/C), and 15.9% SRC solids. Under typical SRC 1 conditions, i.e., 450/sup 0/F, 1425 psi hydrogen, 0.4 residence time, and 39% coal in the feed slurry, yields were 2.9% C/sub 1/-C/sub 4/ hydrocarbons, 16.4% light oil, 56.3% SRC solids, and no heavy distillate. The improved results with the SRC II process are attributed to the more severe operating conditions, to recycle of the coal, allowing additional time for cracking of dissolved high-molecular-weight components in the coal, and to the presence in the SRC solids of mineral matter, which is known to catalyze the SRC reaction.
