摘要
An improved process for the hydrogen fluoride catalyzed alkylation of isoparaffins with olefins wherein better utilization of internal streams is achieved. Isoparaffins used as a stripping medium in the catalyst regeneration zone are reclaimed, free of a hydrogen fluoride phase, and are utilized as recycle isoparaffins to improve the quality of the alkylate product.
