Methods for regenerating a spent catalyst are disclosed. Such methods may employ a step of chlorinating the spent catalyst in the gas phase, followed by decoking the chlorinated spent catalyst, and then fluorinating the de-coked catalyst in a fluorine-containing solution of a fluorine-containing compound.

Methods for regenerating a sulfur-contaminated catalyst are disclosed. Such methods may employ a step of washing the sulfur-contaminated catalyst with an aqueous solution containing an alkali metal, followed by contacting the washed catalyst with a halogen solution containing chlorine and fluorine.

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.
