Abstract
The present invention relates to a catalyst comprising silica and sulphuric acid which impregnates said silica, and the use of said catalyst in catalytic alkylation of isobutane and/or isopentane in the presence of at least one olefin containing 3 to 6 carbon atoms per molecule, said catalyst being characterized in that the silica, prior to its impregnation with sulphuric acid, has a total porous volume greater than 1.5 cm.sup.3 per gram and in that said catalyst consists essentially of particles of an average diameter of between 0.1 and 150 .mu.m.
