ABSTRACT:
A passivation process for decreasing the poisonous effects from contamination by metals, such as vanadium, iron, nickel or copper that can occur during a catalytic conversion of a hydrocarbon feedstock containing such metals is disclosed. The process employs compositions of organic or aqueous media containing one or more, at least partially soluble species of both aluminum and phosphorus-containing materials or species.
