Abstract

Heavy crudes or vacuum residues are treated in a thermal hydroconversion process in the presence of a metal catalyst from Groups IVb, Vb, VIb, VIIb and VIII of the Periodic Table of Elements and water. Fresh catalyst is introduced into the process as a soluble, metallic catalyst precursor which is then decomposed while feedstock admixed with water is preheated to a temperature of at least about 230.degree. C. but no more than about 420.degree. C.
