ABSTRACT:
An improved catalyst demetallization process involves chlorinating the metal contaminated catalyst at elevated temperatures and contacting the chlorinated catalyst with a liquid aqueous composition to produce a demetallized catalyst. Improved catalytic activity is obtained utilizing a catalyst comprising at least one crystalline material capable of promoting the hydrocarbon conversion, and cooling the chlorinated catalyst prior to contact with the liquid aqueous composition. An improved hydrocarbon conversion process is also disclosed.
