Abstract
A process for oligomerizing isobutene comprises contacting a feedstock comprising isobutene with a catalyst comprising a MCM-22 family molecular sieve under conditions effective to oligomerize the isobutene, wherein said conditions including a temperature from about 45° C. to less than 140° C. The isobutene may be a component of a hydrocarbon feedstock containing at least one additional Calkene. In certain aspects, isobutene oligomers are separated from a first effluent of the oligomerization to produce a second effluent comprising at least one n-butene. The second effluent can be contacted with an alkylation catalyst to produce sec-butylbenzene.
