Evans, A J; Hensley, A L

A process is described for the hydrodemetallation, hydrodesulfurization, and hydrocracking of a hydrocarbon feedstock containing asphaltenes, metals, and Shell hot filtration solids precursors and the conversion of at least 30 vol.% of the feedstock fraction boiling over 1,000/sup 0/F to material boiling below 1,000/sup 0/F. The process comprises: (a) contacting the feedstock in a first reaction zone with hydrogen and a demetallation catalyst comprising a Group VIB hydrogenation metal component on a porous inorganic oxide support. The Group VIB metal is present in an amount ranging from about 3.0 to about 8.0 wt.% calculated as an oxide and based on total demetallation catalyst weight, and the catalyst has a surface area of about 150 m/sup 2//gm to about 220 m/sup 2//gm; a total pore volume of about 0.85 to about 1.5 cc/gm; and a pore volume in pores having diameters larger than 1,200A of about 0.15 to about 0.4 cc/gm; and (b) contacting the effluent from the first reaction zone in a second reaction zone with a desulfurization catalyst comprising a hydrogenation metal component comprising a Group VIB metal and a Group VIII metal on a porous inorganic oxide support.
