Alkylation process
First Claim
1. In a process for alkylating at least one alkane containing 2-12 carbon atoms per molecule with at least one alkene containing 2-12 carbon atoms per molecule in the presence of a catalyst comprising trifluoromethanesulfonic acid and at least one solid inorganic material so as to produce at least one product alkane containing more carbon atoms than said at least one feed alkane, the improvement which comprises the presence of at least one tricyclic hydrocarbon selected from the group consisting of dicyclopentadiene, tetrahydrodicyclopentadiene and mixtures thereof in the feed comprising said at least one feed alkane and said at least one feed alkene.

Abstract
The alkylation of C2 -C12 alkanes (preferably isobutane) with C2 -C12 alkenes (preferably butene-2), in the presence of trifluoromethanesulfonic acid on a solid inorganic material as catalyst, is carried out with dicyclopentadiene and/or tetrahydrodicyclopentadiene as additional alkylating agent(s).
