At least one decomposable compound of a metal selected from the group consisting of copper, zinc and the metals of Group III-B, Group IV-B, Group VB, Group VIB, Group VIIB and Group VIII of the Periodic Table is mixed with a hydrocarbon-containing feed stream. The hydrocarbon-containing feed stream

At least one decomposable compound of a metal selected from the group consisting of copper, zinc and the metals of Group III-B, Group IV-B, Group VB, Group VIB, Group VIIB and Group VIII of the Periodic Table is mixed with a hydrocarbon-containing feed stream. The hydrocarbon-containing feed stream containing such decomposable compound is then contacted with a suitable refractory inorganic material to reduce the concentration of metals, sulfur and Ramsbottom carbon residue contained in the hydrocarbon-containing feed stream. The suitable refractory inorganic material may also be slurried with the hydrocarbon-containing feed stream.

A process for hydrofining a hydrocarbon-containing feed stream comprising the steps of: introducing a suitable quantity of a suitable decomposable compound of a metal selected from the group consisting of copper and the metals of Group V-B, Group VI-B, Group VII-B and Group VIII of the Periodic Table into said hydrocarbon-containing feed stream; and contacting said hydrocarbon-containing feed stream containing said decomposable compound under suitable hydrofining conditions with hydrogen and a suitable refractory inorganic material, wherein the concentration of transition metals selected from the group consisting of the metals of copper and Group V-B, Group VI-B, Group VII-B and Group VIII of the Periodic Table in said refractory inorganic material is less than about 1 weight-%, based on the weight of said refractory inorganic material, when said refractory inorganic material is initially contacted with said hydrocarbon-containing feed stream, and wherein said decomposable compound is selected from the group consisting of carbonyls and dithiocarbamates.
