Abstract (en)
[origin: EP0145466A2] A process is described for passivating metal contaminants present in hydrocarbon feedstock (16) which contaminants 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.
