Abstract
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 comprising stripping HF from the spent catalyst, treating the stripped, spent catalyst with hydrogen to provide a stripped hydrotreated catalyst stream, and gravitationally separating the stripped hydrotreated catalyst stream to remove conjunct polymeric byproducts.
