Abstract
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 m.sup.2 /g. Preferably the catalyst has a peak mesopore diameter greater than 165 .ANG., as determined by mercury porosimetry, and an average mesopore diameter greater than 160 .ANG..
