A catalyst composition is prepared by dissolving a suitable oxygen containing compound of a Group VIB metal (preferably Mo), a suitable compound of a Group VIII metal (preferably Ni) and phosphorous acid in water, mixing this solution with an alumina containing support material, and calcining this mixture. This catalyst composition is used primarily for hydrotreating of hydrocarbon feed stream, which contain nitrogen and sulfur impurities, particularly heavy cycle oils.

A process for hydrotreating a hydrocarbon containing feed stream comprising the step of intimately contacting a substantially liquid hydrocarbon containing feed stream, which also contains compounds of sulfur and nitrogen, with a free hydrogen containing gas and a catalyst composition under such hydrotreating conditions as to produce a hydrocarbon containing stream having reduced levels of sulfur and nitrogen, wherein said catalyst composition has been prepared by a process comprising the steps of: (A) mixing (a) at least one oxygen containing compound of a metal belonging to Group VIB of the Periodic Table, (b) at least one compound of a Group VIII metal selected from the group consisting of iron, cobalt and nickel, (c) phosphorous acid containing material, and (d) water, in such amounts and under such conditions as to obtain a solution; (B) mixing the solution obtained in step (A) with an alumina-containing support material; (C) heating the mixture obtained in step (B) at a first temperature under such conditions as to at least partially dry said mixture; and (D) heating the at least partially dried mixture obtained in step (C) in an inert, non-oxidizing and non-reducing atmosphere at a second temperature, which is higher than said first temperature, under such conditions as to activate said mixture.
