LEWIS ACID PROMOTED TRANSITION ALUMINA CATALYSTS AND ISOPARAFFIN ALKYLATION PROCESSES USING THOSE CATALYSTS

摘要

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 BF3), 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.
