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.
Claims14
A catalyst containing silica and an acid phase comprising sulphuric acid, the silica having been impregnated with said acid phase and said catalyst consisting of particles with an average diameter of 0.1 to 150.mu.m, wherein the silica, prior to its impregnation with said acid phase, has a total porous volume of greater than 1.5 cm.sup.3 per gram.
