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.
Claims24
Method of alkylating isoparaffins and olefins which comprises contacting a feedstock comprising isoparaffins and olefins with a catalyst comprising a combination of solid superacid and heteropolyacid or polyoxoanion under alkylation conditions.
A new composition of matter, a heteropolyacid or polyoxoanion supported on a solid superacid comprising a sulfated oxide or hydroxide of a Group III or Group IV element.
