Abstract
The present invention provides a Lewis acid-catalyzed isoparaffin/olefin alkylation process in which acid consumption and energy costs are decreased by employing an acid sorption stage to separate the Lewis acid catalyst from the alkylate product stream, or from a selected fraction of the alkylate product stream, and desorbing the Lewis acid from the sorption stage with an isoparaffin-containing alkylation process feedstream.
