A process is described for hydrotreating a hydrocarbon feed which comprises contacting the feed at a temperature of at least about 150/sup 0/C. and in the presence of hydrogen with a catalyst obtained by compositing a quantity of inorganic refractory oxide support material with one or more precursor salts. Then the composite is heated at elevated temperature of at least about 150/sup 0/C., in the presence of excess sulfur in the form of one or more sulfur-bearing compounds and under oxygen-free conditions for a time sufficient to form the catalyst. The precursor salt contains a tetrathiometallate anion of Mo, W or mixture thereof and a cation comprising trivalent chromium or a mixture of trivalent chromium with one or more divalent promoter metals selected from the group consisting of Fe, Ni, Co, Mn, Zn, and Cu wherein the trivalent chromium and divalent promoter metals are chelated by at least one neutral, nitrogen-containing polydentate ligand, L. The contacting occurs for a time sufficient to hydrotreat at least a portion of the feed.
