Abstract
This invention is a process for the alkylation of isoparaffin with olefins using a catalyst system comprising certain transition aluminas promoted with a Lewis acid (preferably BF.sub.3), and free Lewis acid. The product alkylate is a complex mixture of branched paraffins suitable for use as a high octane blending component for motor fuels.
