Abstract
A method is disclosed for recovering chlorine-containing species from an outlet stream of a zone in which the catalytic metal of a chloride-containing catalyst is reduced. The outlet stream is passed to a sorption zone which contains catalyst and which is maintained at sorption conditions. The catalyst in the sorption zone sorbs the chlorine-containing species from the outlet stream. This method captures and retains within the process the chlorine-containing species that would otherwise be lost from the process and that would need to be replaced by the injection of make-up chlorine-containing species. This method results in a significant savings in capital and operating costs of a catalyst regeneration process that includes a reduction step. This method is adaptable to many catalytic hydrocarbon conversion processes which pass catalyst particles between or among moving bed reaction and regeneration zones.
