Abstract

A process is described for passivating metal contami­ nants present in hydrocarbon feedstock (16) which contami­ nants are deposited on cracking catalyst. The process involves contacting the regenerated catalyst from the regeneration zone (30) with H₂-containing gas (70, 74, 76, 76, 80, 96) in the transfer zone (42, 44) communicating with the regeneration zone and the reaction zone (12). The H₂-containing gas may be added at a plurality of spaced apart locations to the transfer zone and preferably passes through a control means (72) which is regulated by a sensor means (82) analyzing a cracked product and/or by a sensor means (64) monitoring the catalyst circulation rate.
