A process for the catalytic alkylation of an olefin with an isoparaffin comprises: contacting an olefin-containing feed with an isoparaffin-containing feed under alkylation conditions in the presence of a solid acid catalyst comprising a crystalline microporous material of the MWW framework type, wherein the olefin-containing feed comprises propylene and at least one other C.sub.4 to C.sub.12 olefin.

In a process for isoparaffin-olefin alkylation, a feed comprising at least one olefin and at least one isoparaffin is contacted under alkylation conditions in the presence of a solid acid catalyst comprising a crystalline microporous material of the MWW framework type to produce an alkylated product. The alkylated product comprises a C.sub.8− fraction, which is useful as a gasoline blending stock, and a C.sub.9+ fraction, which is separated from the alkylated product and at least partially recycled to the alkylation step.

In a process for isoparaffin-olefin alkylation, a feed comprising at least one olefin and at least one isoparaffin is contacted under alkylation conditions in the presence of a solid acid catalyst comprising a crystalline microporous material of the MWW framework type to produce an alkylated product. The alkylated product comprises a C.sub.8− fraction, which is useful as a gasoline blending stock, and a C.sub.9+ fraction, which is separated from the alkylated product and at least partially recycled to the alkylation step.

A process for the catalytic alkylation of an olefin with an isoparaffin is described in which a feed comprising at least one olefin and at least one isoparaffin is contacted with a solid acid catalyst under alkylation conditions effective for reaction between the olefin and the isoparaffin to produce an alkylated product. The solid acid catalyst comprises a crystalline microporous material of the MWW framework type, the feed comprises at least one C.sub.5+ olefin and/or at least one C.sub.5+ isoparaffin and the alkylated product comprises at least 20% wt % of C.sub.10+ branched paraffins.
