ABSTRACT:
A demetallization process for catalysts used for chemical conversion of hydrocarbons, the catalysts containing at least vanadium as a metal poison, wherein the poisoned catalyst is contacted in a sulfiding zone with a sulfiding agent and a hydrocarbon having a minimum boiling point of about 300.degree. F., the hydrocarbon being at least partially vaporizable at the temperature in the sulfiding zone.
