Patent

CA 2140369

This invention is directed to a catalyst system for use in the alkylation of isoparaffin with olefins. More specifically, this invention is directed to an improved catalyst system containing specified amounts of water and a component of that system com- prising certain transition aluminas promoted with a Lewis acid (preferably BF3). In addition, this invention is a catalytic pro- cess for the alkylation of isoparaffin with olefins. The catalyst component is produced by contacting the transition alumina with the Lewis acid at relatively low temperatures. The catalyst system comprises that component and an additional amount of free Lewis acid. The process entails isoparaffin alkylation with olefins using the catalyst component and its allied catalyst system.
