ABSTRACT:
A passivation process for decreasing the poisonous effects from contamination by metals such as nickel, vanadium and/or iron that can occur during the catalytic conversion of hydrocarbon feedstocks containing such metals is disclosed. The process involves an in situ aluminum passivation for conversion catalysts containing an alumina-containing phase by means of soluble aluminum species contained in that alumina-containing phase.
