ABSTRACT:
Described is a novel acid-soluble oil composition produced as a by-product from an alkylation reaction catalyzed by a sulfone-containing catalyst. Also described is a novel process for regenerating an alkylation catalyst which contains a sulfone component. The regeneration process utilizes alumina adsorbent to remove a substantial portion of the hydrogen halide from the spent catalyst, thereby producing a neutralized stream, which is then treated with carbon to remove a substantial portion of the reaction by-product to produce a sulfone stream substantially free of reaction by-product and hydrogen halide.
