ABSTRACT:
A hydrofining process (preferably hydrovisbreaking process) comprises contacting a substantially liquid hydrocarbon-containing feed stream, which contains Ramsbottom carbon residue and materials boiling in excess of about 1000.degree. F. at atmospheric conditions, with a free hydrogen-containing gas and a catalyst composition comprising at least one catechol compound of molybdenum. Preferably the catechol compound of molybdenum is prepared by reaction of a compound comprising molybdenum and oxygen with a catechol compound under non-reducing conditions.
