Abstract: Described is a novel process for regenerating an ASO contaminated alkylation catalyst which contains a sulfone component and a hydrogen halide component. The alkylation catalyst undergoes a series of separation steps to remove a significant portion of the hydrogen halide component contained therein followed by a phase separation between an ASO phase and a sulfone phase. The sulfone phase is then contacted with a carbon material to remove a portion of any remaining ASO contained in the sulfone.
