ABSTRACT OF THE DISCLOSURE 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°C. The catalyst pre- cursors will be one or more compounds of the formula (ML)(MoyW1-yS4) wherein M comprises one or more di- valent promoter metals selected from the group con- sisting 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.
