A process is described for preparing a supported catalyst, the process comprising compositing a support material with one or more precursor salts and heating the composite at elevated temperature of at least about 150/sup 0/C., in the presence of sulfur 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 promoter metal cation selected from manganese and mixtures of manganese with Ni, Co, Zn, Cu or mixture thereof wherein the promoter metals are chelated by a ligand or mixture thereof, at least one of which is a neutral, nitrogen-containing polydentate ligand.
