  • Patent number: 10167361
    Abstract: A process is provided for converting a mixture of carbon monoxide and molecular hydrogen to an alcohol mixture, which is separated into a first methanol-containing stream and a second C2+ alcohol-containing stream. The first stream's methanol is reacted to produce a mixture of aromatics and aliphatics. The second stream's C2+ alcohol is converted to hydrocarbon including ethylene and propylene.

  • Patent number: 10053633
    Abstract: This disclosure relates to the production of xylenes from syngas, in which the syngas is converted to an aromatic product by reaction with a Fischer-Tropsch catalyst and an aromatization catalyst. The Fischer-Tropsch catalyst and aromatization catalyst may be different catalysts or combined into a single catalyst. The aromatic product is then subjected to selective alkylation with methanol and/or carbon monoxide and hydrogen to increase its p-xylene content.

  • Patent number: 8921633
    Abstract: 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.

  • Patent number: 7759524
    Abstract: 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.
