ABSTRACT:
Self-promoted molybdenum and tungsten sulfide hydrotreating catalysts are 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 are (Cr.sub.x M.sub.1-x L)[Mo.sub.y W.sub.1-y O.sub.4 ].sub.1+.5x wherein M is a divalent promoter metal selected from the group consisting of Mn, Fe, Co, Ni, Cu, Zn and mixtures thereof, x is any value from about 0.2 to 1, y is any value from 0 to 1, and wherein L is a nitrogen-containing, neutral multidentate, chelating ligand. In a preferred embodiment the lligand L will comprise one or more chelating alkyl di- or triamines and the non-oxidizing atmosphere will comprise H.sub.2 S.
