ABSTRACT:
Partially deactivated hydrocarbon conversion catalysts comprising (a) one or more Lewis acids of the formula MX.sub.n where M is a metal selected from Group III-A, IV-B, V or VI-B elements of the Periodic Table, X is a halogen, n is the ratio of halogen atoms to atoms of M and varies from 1-8, and (b) a strong Bronsted acid are contacted with a hydrocarbon feedstock to recover the active or potentially active catalyst species from the partially deactivated catalyst stream prior to regeneration. In addition, potential organic and inorganic catalyst poisons present in said feedstock are removed therefrom during said contacting prior to introducing said feedstock into a hydrocarbon conversion process.
