Catalyst for alkylation of C4-C5 isoparaffin by at least one C3-C6 olefin

The present invention relates to a catalyst comprising silica and an acid phase comprising sulphuric acid and the compound HB(HSO4)4, the silica having been impregnated by said acid phase, said catalyst being such that is consists essentially of particles of an average diameter of between 0.1 and 15...

Beschreibung
Zusammenfassung:	The present invention relates to a catalyst comprising silica and an acid phase comprising sulphuric acid and the compound HB(HSO4)4, the silica having been impregnated by said acid phase, said catalyst being such that is consists essentially of particles of an average diameter of between 0.1 and 150 mu m, its content by weight of acid phase is greater than 40%, the silica, prior to its impregnation with said acid phase, has a total porous volume of between 0.5 and 6 cm3 per gram and said acid phase contains between 0.4% and 68.8% by weight of the compound HB(HSO4)4, said acid phase containing neither sulphuric anhydride nor boric acid. The invention also relates to the preparation and 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.
