Abstract
Catalyst based on silica and sulfuric acid and its use in the catalytic alkylation of isobutane and/or isopentane in the presence of at least one olefin having 3 to 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.
