Patent ID: 8664144

Claim:
A method comprising: (a) employing a fresh aromatization catalyst in one or more reaction zones for a time period sufficient to produce a spent catalyst; (b) reducing the amount of carbonaceous material associated with the spent catalyst to produce a decoked spent catalyst; (c) contacting the decoked spent catalyst with a redispersing composition to produce a decoked redispersed spent catalyst; (d) contacting the decoked redispersed spent catalyst with a reactivating composition to produce a decoked, redispersed, reactivated spent catalyst; and (e) thermally treating the decoked, redispersed, reactivated spent catalyst to produce a reactivated catalyst, wherein the reactivating composition comprises a fluorine-containing compound in a gas phase, wherein the fluorine-containing compound comprises fluorine, hydrofluoric acid, perfluorinated alkane, perfluorinated alcohol, or mixtures thereof.
