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°C. but no more than about 420°C.
A thermal hydroconversion process for a hydrocarbon feedstock containing asphaltenes and metals which comprises the steps of (a) combining said feedstock with water, with a metallic catalyst precursor soluble in the feedstock and containing a metal catalyst which is a member of the group consisting of Groups IVB, VB, VIB, VIIB and VIII of the Periodic Table of Elements, and with a liquid recycle stream containing said metal catalyst in an amount of about 400 to about 15000 parts of said metal catalyst per million parts by weight of said recycle stream to...
