Patent number: 8921633Abstract: In a hydrocarbon upgrading process, a hydrocarbon feed is treated in at least one of a steam cracker, catalytic cracker, coker, hydrocracker, and reformer under suitable conditions to produce a first stream comprising olefinic and aromatic hydrocarbons. A second stream composed mainly of C4 to C12+ olefinic and aromatic hydrocarbons is recovered from the first stream and blended said second stream with a residual fraction from a steam cracker or an atmospheric or vacuum distillation unit to produce a third stream. The third stream is then catalytically pyrolyzed in a reactor under conditions effective to produce a fourth stream having an increased benzene and/or toluene content compared with said second stream and a C3-olefin by-product. The C3-olefin by-product is recovered and benzene and/or toluene are recovered from the fourth stream.Type: GrantFiled: May 7, 2012Date of Patent: December 30, 2014Assignee: ExxonMobil Chemical Patents Inc.Inventors: Larry L.

Patent number: 7759524Abstract: In a process for producing phenol and methyl ethyl ketone, benzene and a C4 olefin are contacted under alkylation conditions and in the presence of an alkylation catalyst to produce sec-butylbenzene. The sec-butylbenzene is then oxidized to produce an oxidation effluent comprising sec-butylbenzene hydroperoxide and acetophenone. At least part of the sec-butylbenzene hydroperoxide in the oxidation effluent is cleaved to produce phenol and methyl ethyl ketone, while at least part of the acetophenone is hydrogenated to produce at least one of methyl benzyl alcohol, styrene and ethylbenzene.Type: GrantFiled: December 18, 2008Date of Patent: July 20, 2010Assignee: ExxonMobil Research and Engineering CompanyInventors: John Scott Buchanan, Jihad Mohammed Dakka, Stephen Zushma, Francisco Manuel Benitez, Steven E.
