[Also in Division C5] Alkylation catalysts are made by impregnating a SiO 2 carrier with P 2 O 5 or a precursor therefrom and calcining the impregnated carrier, which itself consists of an agglomerate of SiO 2 hydrogel micro-spheres having a diameter of 100-800Á. The carrier may have a surface area of 200m2/gm or more and a pore volume of 1-1.5 cm3/g. The P 2 O 5 precursor may be ortho-, pyro-, meta- or poly-phosphoric acid. Subsequently the catalysts may be calcined e.g. for 2 hours at 450‹C. French Specification 1,544,156 is referred to.
