    Abstract: 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.

    Abstract translation: 一种重新激活包含金属和催化剂载体的废催化剂的方法，所述方法包括将废金属重新分散在废催化剂中以产生再分散的废催化剂，使再分散的废催化剂与再活化组合物接触以产生再分散的再活化的废催化剂， 并对再分散的再活化的废催化剂进行热处理以产生再活化的催化剂。 一种方法，包括在一个或多个反应区中使用新鲜的芳构化催化剂足以产生废催化剂的时间段，减少与废催化剂相关的碳质材料的量以产生经过处理的废催化剂，将经过处理的废催化剂与 再分散组合物以产生经过重新分配的再分散的废料，使经过重新分离的废催化剂与再活化组合物接触，以产生经过重新分离的再分解的再生废催化剂，并热处理所述经切割的再活化的废催化剂以产生再活化的催化剂。
