Abstract
Impregnated catalyst based on silica and a solid state sulfuric acid and its use in the catalytic alkylation of isobutene and/or isopentane in the presence of at least one olefin having 3-6 carbon atoms per molecule. The catalyst may contain an additive, e.g., B(OH).sub.3, HBF.sub.4, H.sub.3 PO.sub.4, FSO.sub.3 H, CF.sub.3 SO.sub.3 H, SbF.sub.5, CF.sub.3 COOH, and SO.sub.3.
