Abstract
A catalyst composition comprises (a) alumina, (b) zinc titanate, (c) at least one compound of molybdenum, (d) at least one compound of at least one of nickel and cobalt, and (e) at least one compound containing phosphorus and oxygen. This catalyst composition is used for hydrotreating a liquid hydrocarbon-containing feed stream (such as a heavy oil) which contains compounds of nickel, vanadium and sulfur, under such conditions as to obtain a product having reduced levels of nickel, vanadium and sulfur.
