Zusammenfassung:	An improved process for upgrading a coal liquid where the coal liquid is catalytically converted by hydrogenating and hydrocracking. In the process of upgrading a coal liquid where the coal liquid is fed with hydrogen into a catalytic reactor, the improvement comprises the feeding of a sulfur-containing liquid with the coal liquid. The sulfur-containing liquid ranges from about 0.2 to about 2.0 weight percent of the coal liquid feed. The sulfur-containing liquid is a high boiling hydrocarbon sulfur compound of the formula RSR1, where R is an alkyl group having 2 to 20 carbon atoms or a phenyl group and R1 is H, an alkyl group having 2 to 20 carbon atoms or a phenyl group.
