ABSTRACT:
The present invention provides a method for separating conjunct polymers which are formed as byproducts of acid catalyzed isoparaffin-olefin alkylation and sulfolane from a mixture containing conjunct polymers, sulfolane, and hydrofluoric acid, and for minimizing accumulation of conjunct polymeric byproducts in the recycled acid catalyst.
