2092569 9204977 PCTABS00011 This invention is to: a) a catalyst system, b) a component of that system comprising certain transition aluminas promoted with a Lewis acid (preferably BF3), and c) a catalytic process 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 or at those temperatures at which certain characteristic peaks appear in the component's nuclear magnetic resonance (NMR) spectrum. The catalyst system comprises that component and an additional amount of free Lewis acid. The process entails olefin/isoparaffin alkylation using the catalyst component and its allied catalyst system.
