Abstract:
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.

Claim (Index 23):
A method for regenerating a chlorinated spent catalyst comprising a transition metal and a catalyst support, the method comprising:\n (i) contacting the chlorinated spent catalyst with a decoking gas stream comprising oxygen to produce a de-coked chlorinated catalyst, wherein the chlorinated spent catalyst comprises from about 0.5 wt. % to about 3 wt. % of chlorine; and (ii) contacting the de-coked chlorinated catalyst with a fluorine-containing solution comprising a fluorine-containing compound in the liquid phase to produce a fluorinated catalyst; wherein: the transition metal comprises a Group 8-11 transition metal; and the catalyst support comprises a large pore zeolite having an average pore diameter in a range of from about 7 \u212b to about 12 \u212b.
