Abstract
Hydrocarbon-containing feed streams, which contain at least about 5 ppmw nickel and at least about 10 ppmw vanadium, are hydrodemetallized either (I) in the presence of a catalyst composition consisting essentially of (a) a support material (preferably alumina), and (b) at least one lanthanide metal compound (preferably CeO.sub.2 and/or Ce.sub.2 O.sub.3); or (II) in the presence of a catalyst composition comprising (a) a support material (preferably alumina), (b) at least one lanthanide metal compound (preferably La.sub.2 O.sub.3) and (c) at least one manganese compound (preferably at least one manganese oxide).
