摘要:
A method of reactivating a spent catalyst comprising a metal and a catalyst support, the method comprising redispersing the metal in the spent catalyst to produce a redispersed spent catalyst, contacting the redispersed spent catalyst with a reactivating composition to produce a redispersed, reactivated spent catalyst, and thermally treating the redispersed, reactivated spent catalyst to produce a reactivated catalyst. A method comprising employing a fresh aromatization catalyst in one or more reaction zones for a time period sufficient to produce a spent catalyst, reducing the amount of carbonaceous material associated with the spent catalyst to produce a decoked spent catalyst, contacting the decoked spent catalyst with a redispersing composition to produce a decoked redispersed spent, contacting the decoked redispersed spent catalyst with a reactivating composition to produce a decoked redispersed reactivated spent catalyst, and thermally treating the decoked, reactivated spent catalyst to produce a reactivated catalyst.
