ABSTRACT:
Hydrocarbon feeds are upgraded by contacting a feed, at elevated temperature and in the presence of hydrogen, with a self-promoted catalyst prepared by heating one or more catalyst precursors under oxygen-free conditions in the presence of sulfur at a temperature of at least about 150.degree. C. The catalyst precursors will be one or more compounds of the formula (ML) (Mo.sub.y W.sub.1-y S.sub.4) wherein M comprises one or more divalent promoter metals selected from the group consisting of Ni, Co, Zn, Cu and mixtures thereof, wherein y is any value ranging from 0 to 1 and wherein L is one or more neutral, nitrogen-containing ligands at least one of which is a chelating, polydentate ligand.
