ABSTRACT:
Hydrocarbon feeds are upgraded by contacting same, at elevated temperature and in the presence of hydrogen, with a self-promoted catalyst prepared by heating one or more water soluble catalyst precursors in a non-oxidizing atmosphere in the presence of sulfur at a temperature of at least about 200.degree. C. The precursors will be one or more compounds of the formula ML(Mo.sub.y W.sub.1-y O.sub.4) wherein M is one or more promoter metals selected from the group consisting essentially of Mn, Fe, Co, Ni, Cu, Zn and mixtures thereof, wherein O.ltoreq.y.ltoreq.1 and wherein L is a nitrogen containing, neutral multidentate, chelating ligand. In a preferred embodiment the ligand L will comprise one or more chelating alkyl di or triamines and the non-oxidizing atmosphere and to form the catalyst will comprise H.sub.2 S.
