Abstract
The present invention provides a process for alkylating an isoparaffin with an olefin comprising contacting an isoparaffin having from 4 to 8 carbon atoms with an olefin having from 2 to 12 carbon atoms in an alkylation reaction zone at temperature from about -20.degree. C. to about 200.degree. C. in the presence of a Bronsted acid and an inorganic, porous crystalline phase material having, after calcination, a d-spacing greater than about 18 Angstrom Units and having a benzene adsorption capacity of greater than 15 grams benzene per 100 grams of said material at 50 torr and 25.degree. C., wherein the molar ratio of said isoparaffin to said olefin is from about 1:1 to about 250:1 to evolve a product stream containing C.sub.5 + alkylate. In a preferred embodiment, the alkylation catalyst complex comprises a Bronsted acid and an inorganic, porous crystalline phase material having, after calcination, a hexagonal arrangement of uniformly-sized pores having diameters of at least about 13 Angstrom Units and exhibiting a hexagonal electron diffraction pattern that can be indexed with a d.sub.100 value greater than about 18 Angstrom Units.
