ABSTRACT:
There is provided a catalyst comprising a heteropoly acid, such as phosphotungstic acid, supported on a mesoporous crystalline material, such as M41S. A particular form of this M41S support is designated as MCM-41. There is also provided a method for preparing this catalyst by impregnating the heteropoly acid on the support. There is also provided a process for using this catalyst to catalyze acid catalyzed reactions, such as the isomerization of paraffins and the alkylation of aromatics.
