摘要：
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. Treatment conditions are such that coke and vanadium in an oxidation state less than + 5 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 under conditions keeping vanadium in an oxidation state less than +5 and regenerated sorbent is recycled to the treatment zone for contact with fresh feed.
