Abstract

Abstract A catalyst composition is provided which comprises a cobaltmolybdenum impregnated magnesium aluminate spinel having a surface area of greater than about 50m2/g and a pore volume of greater than about 0.3 cc/g. Also provided is a process for demetalation and desulfurization of oil stock which comprises contacting said oil stock in the presence of hydrogen with a catalytically effective amount of said cobalt-molybdenum impregnated magnesium aluminate spinel at a temperature of from about 600*F to about 1,000*F and a liquid hourly space velocity of from about 0.1 to about 2.
