A process is disclosed for the conversion of a hydrocarbon oil feed having a significant content of vanadium to lighter oil products by contacting the feed under conversion conditions in a conversion zone with a catalyst containing a metal additive to immobilize vanadium compounds. Conversion conditions are such that coke and vanadium are deposited on the catalyst in the conversion zone. Coked catalyst is regenerated in the presence of an oxygen containing gas at a temperature sufficient to remove the coke and regenerated catalyst is recycled to the conversion zone for contact with fresh feed. The metal additive is present on the catalyst in an amount sufficient to immobilize the vanadium compounds in the presence of oxygen containing gas at the catalyst regeneration temperature. A catalyst composition comprises a crystalline alumino-silicate zeolite dispersed in an amorphous inert solid matrix containing the metal additive, which may be introduced into the catalyst during the conversion process or during catalyst manufacture. Metal additives include water soluble inorganic metal salts and hydrocarbon soluble inorganic metal salts and hydrocarbon soluble organometallic compounds of select metals.
