Abstract
A process for isoparaffin-olefin alkylation is provided that permits the use of solid acid catalysts which require frequent regeneration and high isoparaffin/olefin ratios. The process comprises circulating in a reactor a slurry comprising solid acid zeolite catalyst particles (20-2000 microns) and feed of liquid reactants comprising isoparaffins and olefins in an isoparaffin to olefin molar ratio of less than 100, recycling a first portion of said slurry to provide an isoparaffin to olefin molar ratio in the reactor of at least 500, passing a second portion of the slurry to a separating means to separate alkylate product from said solid catalyst particles, and regenerating the catalyst particles.
