A process for the hydrotreatment of a sulfur and metal-containing hydrocarbon feed comprises contacting said feed with hydrogen and a catalyst in a manner such that the catalyst is maintained at isothermal conditions and is exposed to a uniform quality of feed, where said catalyst has a composition

A process for the hydrotreatment of a sulfur and metal-containing hydrocarbon feed comprises contacting said feed with hydrogen and a catalyst in a manner such that the catalyst is maintained at isothermal conditions and is exposed to a uniform quality of feed, where said catalyst has a composition comprising 3.0-5.0 wt. % of an oxide of a Group VIII metal, 14.5-24.0 wt. % of an oxide of a Group VIB metal and 0-2.0 wt. % of an oxide of phosphorus supported on a porous alumina support, and said catalyst is further characterized by having a total surface area of 150-210 m2/g and a total pore volume of 0.50-0.75 cc/g with a pore diameter distribution such that micropores having diameters of 100-160A constitute 70-85% of the total pore volume of said catalyst and macropores having diameters of greater than 250A constitute 5.5-22.0% of the total pore volume of said catalyst. The process of the instant invention is particularly effective in achieving desired levels of hydrodesulfurization in the fraction of hydrotreated/hydrocracked petroleum resid product having a boiling point greater than 1000°F.
