ABSTRACT:
A process is disclosed for the treatment of a hydrocarbon oil feed having a significant content of vanadium to provide a higher grade of oil products by contacting the feed under treatment conditions in a treatment zone with sorbent material containing a metal additive to immobilize vanadium compounds. Treatment conditions are such that coke and vanadium are deposited on the sorbent in the treatment zone. Coked sorbent is regenerated in the presence of an oxygen containing gas at a temperature sufficient to remove the coke, and regenerated sorbent is recycled to the treatment zone for contact with fresh feed. The metal additive is present on the sorbent in an amount sufficient to immobilize the vanadium compounds in the presence of oxygen containing gas at the sorbent regeneration temperature. A sorbent composition disclosed comprises a kaolin clay containing the metal additive, which may be introduced into the clay during the treatment process or during sorbent manufacture. Metal additives include water soluble inorganic metal salts and hydrocarbon soluble organo-metallic compounds of select metals.
