Hydrotreating catalyst composition comprising a hydrogenating component consisting essentially of a metal component in which the metal is selected from Group VIB and a phosphorus component, deposed on the surface of a support comprising a porous refractory inorganic oxide and free of zeolite component exhibits excellent hydrotreating activity and lifetime, particularly in the hydrodenitrogenation of high nitrogen feeds, e.g., whole shale oils or fractions thereof, and in the hydrodesulfurization and hydrodemetallation of high sulfur feeds, e.g., vacuum or atmospheric residual.

A process for hydrotreating a feedstock consisting essentially of a whole shale oil wherein the feedstock contains at least one component selected from the group consisting of sulfur, nitrogen and metals, wherein said process comprises contacting the feedstock with hydrogen under hydrotreating conditions and in the presence of a catalyst comprising a hydrogenating component consisting essentially of (1) at least one Group VIB metal component and (2) a phosphorus component, deposed on the surface of a support component comprising a porous refractory inorganic oxide and free of a zeolite component. A process for the hydrodemetallation and hydrodesulfurization of a hydrocarbon feedstock containing asphaltenes and a substantial amount of metals, said feedstock consisting essentially of a whole shale oil which process comprises: (a) contacting said feedstock in a first reaction zone with hydrogen and a first-stage catalyst comprising (1) a hydrogenation metal component comprising at least one member selected from the group consisting of Group VIB metals and Group VIII metals, and (2) a porous inorganic oxide support, said hydrogenation metal being in at least one form selected from the group consisting of the elemental form, the oxide, and the sulfide, and said catalyst having a surface area of about 100 m2/gm to about 400 m2/gm, a pore volume of about 0.7 cc/gm to about 1.7 cc/gm, and an average pore diameter of about 125Åto about 350Å; and (b) contacting the effluent from the first reaction zone in a second reaction zone with a second-stage catalyst comprising a hydrogenating component consisting essentially of (1) a metal component in which the metal is selected from Group VIB and (2) a phosphorus component, deposed on the surface of a support comprising a porous refractory inorganic zeolite component, and having a pore volume within the range of about 0.4 cc/gm to about 0.9 cc/gm, a surface area within the range of about 130 m2/gm to about 300 m2/gm, an average pore diameter within the range of about 90 Åto about 160 Å, and a pore volume distribution such that less than about 40% of its total pores volume is in pores having diameters within the range of about 50 Åto about 80 Å, about 45% to about 90% of its total pore volume is in pores having diameters within the range of about 80 Åto about 130 Å, and less than about 15% of its total pore volume is in pores having diameters greater than 130 Å.
