For a heavy hydrocarbonaceous feed, especially good hydrodemetalation and hydrodesulfurization are achieved, as well as MCR reduction, using a catalyst having 5 to 11 percent of its pore volume in the form of macropores, and a surface area greater than 75 m2/g. Preferably the catalyst has a peak mesopore diameter greater than 165 Å, as determined by mercury porosimetry, and an average mesopore diameter greater than 160 Å.
A process for hydrodemetalation and hydrodesulfurization of a high-boiling point, hydrocarbonaceous feed, comprising: contacting the feed in the presence of hydrogen gas and at a temperature between 600°F. and 1000°F. and a pressure between 100 and 10,000 psig with a catalyst comprising a hydrogenation component selected from Group VI and Group VIII metals, and a refractory inorganic oxide support, and wherein the catalyst has a. 5 to 11 percent of its pore volume in the form of macropores, and b. a surface area greater than 75 m2/g of catalyst.
