ABSTRACT:
A non-stoichiometric vanadium sulfide catalyst utilized in a process for hydrorefining a hydrocarbon feed stock is prepared by (1) contacting vanadium oxide with ammonium sulfide to form an ammonium salt of vanadium sulfide and (2) the salt is neutralized with an acid in a non-oxidative atmosphere to form the vanadium sulfide catalyst. The acid used in the neutralizing step may be sulfuric acid or carbonic acid and the non-oxidative atmosphere may be hydrogen or nitrogen.
