ABSTRACT OF THE DISCLOSURE Hydrocarbon feeds are upgraded by contacting a feed, at elevated temperature and in the presence of hydrogen, with a supported self-promoted catalyst pre- pared by heating a composite of support material and one or more catalyst precursor salts under oxygen- free conditions and in the presence of sulfur at a temperature of at least about 250°C. The precursor salt or salts will be of the general formula (ML)(MoyW1-yS4) wherein M comprises one or more pro- moter metals selected from the group consisting essen- tially of Mn, Fe, Co, Ni, Zn 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.
