ABSTRACT:
A process for the hydrofluoric acid-catalyzed alkylation of an isoparaffin with an olefin in a gravity-flow hydrofluoric acid alkylation reaction system. The process is effected without benefit of an acid regenerator. Regeneration is effected an isostripper column, and catalyst-contaminating polymeric products of the alkylation are recovered in the normally liquid alkylate product substantially free of hydrofluoric acid.
