ABSTRACT:
Disclosed is an alkylation process which utilizes a mixture of sulfone and hydrogen fluoride as an alkylation catalyst. The process provides for the regeneration of an alkylation catalyst having ASO therein by separating HF from the ASO and sulfone components. The ASO and sulfone are thereafter separated to provide sulfone which is substantially free of ASO.
