ABSTRACT:
A visbreaking process for the conversion of heavy residual petroleum charge stocks is provided in which an organic sulfur compound containing a thiol sulfur is added to said petroleum charge stock and the visbreaking reaction is carried out at increased severities in the presence of highly aromatic petroleum refinery hydrogen-donor materials which are characterized by an H.sub.Ar proton content between about 20 and 50 percent and an H.sub..alpha. proton content of at least about 20 percent. Typcial hydrogen-donor materials include FCC main column bottoms, clarified slurry oil and light cycle oil.
