Abstract:
The present invention provides a composite solid acid catalyst consisting of from 50%-80% by weight of a porous inorganic support, from 15% to 48% by weight of a heteropoly compound loaded thereon, and from 2% to 6% by weight of an inorganic acid. The present invention further provides a process for preparing said composite solid acid catalyst and a process for conducting an alkylation reaction by using such catalyst. The composite solid acid catalyst of the present invention has the acid sites type of Brönsted acid and has an acid sites density of not less than 1.4×10−3 mol H+/g. Moreover, said composite solid acid catalyst has the homogeneous acid strength distribution, and is a solid acid catalyst having excellent performances.
