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 preparing a composition of matter 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 obtaining in step (A) with an alumina-containing support material; (C) heating the mixture obtained in step (B) at a...
