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.

Supported heteropoly acid catalysts

The alkylation of isoparaffin with olefin to provide alkylate is carried out in the presence of, as catalyst, a supported heteropoly acid. The support may be MCM-41, and the heteropoly acid may be dodecawolframophosphoric acid (i.e., phosphotungstic acid, i.e., H.sub.3 PW.sub.12 O.sub.40).

Supported heteropoly acid catalysts for isoparaffin-olefin alkylation

There is provided a catalyst comprising MCM-36 and a hydrogenation/dehydrogenation component. A particular example of such a catalyst comprises MCM-36, nickel and tungsten.

Catalyst comprising MCM-36 and a hydrogenation/dehydrogenation component

There is provided a hydrocracking process with a catalyst comprising MCM-36.
