PROCESS FOR DEMETALLATION AND DESULFURIZATION OF HEAVY HYDROCARBONS ABSTRACT Disclosed is a multiple-stage catalytic process for hydrodemetallation and hydrodesulfurization of heavy hydrocarbon streams containing asphaltenes and a sub- stantial amount of metals. The first stage of this process comprises contacting the feedstock in a first reaction zone with hydrogen and a demetallation catalyst comprising hydro- genation metal selected from Group VIB and/or Group VIII deposed on a large-pore, high surface area inorganic oxide support; the second stage of the process comprises con- tacting the effluent from the first reaction zone with a catalyst consisting essentially of hydrogenation metal selected from Group VIB deposed on a smaller pore, catalytically active support comprising alumina, said second stage catalyst having a surface area within the range of about 150 m2/gm to about 300 m2/gm, an average pore diameter within the range of about 90 .ANG. to about 160 .ANG., and the catalyst has a pore volume within the range of about 0.4 cc/gm to about 0.9 cc/gm.
