ABSTRACT:
A hydrotreating (hydrovisbreaking) process comprises the step of contacting under suitable conditions (A) a substantially liquid hydrocarbon-containing feed stream containing more than 0.1 weight-% Ramsbottom carbon residue, (B) a hydrogen-containing gas and (C) a liquid catalyst composition, which has been prepared by mixing (a) water, (b) at least one alkali metal sulfide or hydrogen sulfide or ammonium sulfide or hydrogen sulfide and (c) at least one molybdenum-oxygen compound, wherein the atomic ratio of S:Mo in this liquid catalyst composition is in the range of from about 0.6:1 to about 3.0:1, preferably from about 0.8:1 to 2.3:1. Preferably, (b) is (NH.sub.4).sub.2 S and (c) is MoO.sub.3.
