Abstract
Isoparaffins and olefins are alkylated by contact with a solid superacid such as sulfated zirconia optionally containing added metals, and containing added heteropolyacids (HPA's) or polyoxoanions (POA's). The presence of HPA's or POA's in the solid superacid catalyst results in higher yields of desired high-octane components in the product mixture than are obtained in the absence of HPA's or POA's.
