ABSTRACT:
A process for treating a catalyst contaminated with at least one metal which was so contaminated while promoting conversion of a substantially hydrocarbon feedstock containing the metal comprising at least one of the following: (1) contacting the catalyst component to increase the ammonium ion-containing component to increase the ammonium ion content of the catalyst; and (2) contacting the catalyst with at least one rare earth metal ion-containing component to increase the rare earth metal ion content of the catalyst. Improved hydrocarbon conversion processes are also disclosed.
