| description | An additive comprising a mixture of at least one decomposable molybdenum compound selected from the group consisting of molybdenum dithiophosphates and molybdenum dithiocarbamates and at least one decomposable nickel compound selected from the group consisting of nickel dithiophosphates and nickel dithiocarbamates is mixed with a hydrocarbon-containing feed stream. The hydrocarbon-containing feed stream containing the additive is then contacted in a hydrofining process with a catalyst composition comprising a support selected from the group consisting of alumina. silica and silica-alumina 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 inventive additive may be commenced when the catalyst is new, partially deactivated or spent with a beneficial result occuring in each case. |
