Patent number: 9029621Abstract: 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 C4 alkene. 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.Type: GrantFiled: October 2, 2008Date of Patent: May 12, 2015Assignee: ExxonMobil Chemical Patents Inc.Inventors: John Scott Buchanan, Jane Chi-Ya Cheng, Jihad Mohammed Dakka, Jon Edmond Stanat
