Abstract
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).
Claims12
An isoparaffin/olefin alkylation process which comprises reacting isoparaffin and olefin under alkylation conditions providing an alkylate product in the presence of, as catalyst, a supported heterpoly acid, wherein said heteropoly acid comprises at least one element selected from the group consisting of P, Si, B, Ge, As, Se, Ti, Zr, Mn, F, V, Ce, and Th as a central element and at least one element selected from the group consisting of Mo, W, V, Mn, Co, Ni, Cu, Zn, and Fe as a coordinating element.
