Methods of regenerating aromatization catalysts |
摘要 |
Methods for treating or rejuvenating a spent catalyst are described. These 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. |

1. A method of treating a spent catalyst comprising a transition metal and a catalyst support, the method comprising:
(1) contacting the spent catalyst with a fluorine-containing stream comprising a fluorine-containing compound to produce a fluorinated spent catalyst; (2) contacting the fluorinated spent catalyst with a chlorine-containing stream comprising a chlorine-containing compound to produce a fluorinated-chlorinated spent catalyst; and (3) contacting the fluorinated-chlorinated spent catalyst with a decoking gas stream comprising oxygen. |
