métodos para tratar um catalisador gasto compreendendo um metal de transição e um suporte de catalisador, processos de reforma. métodos para tratar ou rejuvenescer um catalisador gasto são divulgados. tais métodos podem empregar uma etapa d e halogenação do catalisador gasto, seguida por descoqueamento do catalisador gasto halogenado. a etapa de halogenação pode utilizar flúor e cloro juntos, ou flúor e cloro podem ser aplicados sequencialmente. Methods for treating or rejuvenating a spent catalyst are disclosed. Such methods can employ a step of halogenating the spent catalyst, followed by decoking the halogenated spent catalyst. The halogenation step can utilize fluorine and chlorine together, or fluorine and chlorine can be applied sequentially.
