Large pore shaped hydroprocessing catalysts

A catalyst for hydroprocessing heavy hydrocarbonaceous feedstocks that contain at least 10 ppm nickel plus vanadium comprising:

• a porous shaped catalyst particle comprising an elongated extrudate having an asymmetric quadralobe cross-section characterized by having the centers of the four component circles define two substantially equilateral triangles joined on a base, having substantially all of the points within said particle within 0.02 inch from the nearest external surface of said particle, said particle having an average pore diameter within the range of 120 Angstroms to 700 Angstroms, said particle having between 4 and 15 weight percent of a catalytic metal from Group VIB and between 0 and 10 weight percent of a catalytic metal from Group VIII;
• where said weight percents are based on the catalytic metals content of the total particle weight, calculated as reduced metal, such that when contacted with a heavy hydrocarbonaceous feedstock containing at least 10 ppm nickel plus vanadium under hydroprocessing conditions substantial metal penetration occurs to a depth of at least 0.012 inch from the nearest surface of said support.
