摘要：A coal solvation/liquefaction process wherein the coal is contacted with hydrogen and an octahydrophenanthrene-enriched solvent containing OHP and THP in a ratio of OHP/THP greater than 0.4, wherein the OHP is present in an amount of at least 5 percent by weight based upon the total weight of said solvent. The OHP-enriched solvent provides improved coal solvation and increases the production of distillate liquid (62) in a coal solvation/liquefaction (20, 24) process. The desired ratio of OHP/THP is provided by catalytic hydrogenation (68) of a coal liquid distillate stream (64). By increasing the OHP/THP ratio to a value greater than 1, the amount of hydrogen consumed in the process can be significantly reduced.
