A process is disclosed for the treatment of a hydrocarbon oil feed having a significant content of metals to lighter oil products by contacting the feed under conversion conditions in a conversion zone with a catalyst containing a sacrificial trap material sufficient to immobilize Ni-V-Na compounds. Conversion conditions are such that carbonaceous material and metals are deposited on the catalyst in the conversion zone. The catalyst is regenerated in the presence of an oxygen containing gas at a temperature sufficient to remove the carbonaceous deposits, and regenerated catalyst is recycled to the conversion zone for a contact with fresh feed. The sacrificial trap material is present on the catalyst in an amount sufficient to substantially immobilize the metal compounds in the presence of oxygen containing gas at the catalyst regeneration temperature. A catalyst composition for the above conversion comprises a catalytically active alumino-silicate zeolite dispersed in an amorphous inert solid matrix material containing the sacrificial trap material with or without one or more selected metal additives. The sacrificial trap material preferable includes inexpensive naturally occurring or synthetic zeolites which can be ion exchanged with water soluble metal additives.
