ABSTRACT:
The present invention relates to a catalyst composition, its methods of preparation and its use in aromatic alkylation processes. The composition comprises a heteropoly compound selected from the group consisting of heteropoly salts and heteropolyacid salts deposited in the interior of a porous support selected from the group consisting of silica, titania, and zirconia, wherein said salt of said heteropoly salt and said heteropolyacid salt is selected from the group consisting of ammonium, cesium, potassium, and rubidium salts and mixtures thereof, and wherein said heteropoly salt and said heteropolyacid salt are formed with a heteropolyacid selected from the group consisting of 12-tungstophosphoric, 12-tungstosilicic, 12-molybdophosphoric, and 12-molybdosilicic acid.
