The reaction product of a mercaptoalcohol and a molybdenum compound selected from the group consisting of molybdic acids, alkali metal salts of molybdic acids and ammonium salts of molybdic acids is mixed with a hydrocarbon-containing feed stream. The hydrocarbon-containing feed stream containing such reaction product is then contacted in a hydrofining process with a catalyst composition comprising a support selected from the group consisting of Al2O3, SiO2, Al2O3-SiO2, Al2O3-TiO2, Al2O3-P2O5, Al2O3-BPO4, Al2O3-AlPO4, Al2O3-Zr3(PO4)4, Al2O3-SnO2 and Al2O3-ZnO and a promoter comprising at least one metal selected from Group VIB, Group VIIB and Group VIII of the Periodic Table. The introduction of the reaction product may be commenced when the catalyst is new, partially deactivated or spent with a beneficial result occuring in each case.
