ABSTRACT OF THE DISCLOSURE A decomposable compound selected from compounds of the metals of Group IVA of the Periodic Table (for example silicone) is mixed with a hydrocarbon-containing feed stream. The hydrocarbon-containing feed stream containing such decomposable compound is then contacted with a catalyst composition having a support of alumina, silica and silica-alumina and as promoters at least one Group VIB metal and at least one iron Group VIII metal. The introduction of the decomposable compound can be commenced when the catalyst is new, partially deactivated or spent with a beneficial result on the catalyst's ability to remove nitrogen, sulfur, or other contaminants from various petroleum feedstreams by hydrotreating.
