  • Publication number: 20130296622
    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+ olefinic and aromatic hydrocarbons is recovered from the first stream and is fed together with a methylating agent to a reaction zone containing a catalyst under reaction conditions including a temperature of about 450° C. to about 700° C., such that aromatics components in the second stream undergo dealkylation, transalkylation and/or methylation and aliphatic components undergo cracking and aromatization to produce a third stream having an increased xylene content compared with said second stream and a C3? olefin by-product. The C3? olefin by-product is recovered and para-xylene is removed from at least part of said third stream.

  • Publication number: 20130296624
    Abstract: A hydrocarbon upgrading process is described in which 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 aliphatic and aromatic hydrocarbons. A second stream comprising C6-C9 aliphatic and aromatic hydrocarbons is recovered from the first stream and aliphatic hydrocarbons are removed from at least part of the second stream to produce an aliphatic hydrocarbon-depleted stream. The aliphatic hydrocarbon-depleted stream is then dealkylated and/or transalkylated and/or cracked (D/T/C) by contact with a catalyst under suitable reaction conditions to produce a third stream having an increased benzene and/or toluene content compared with said aliphatic hydrocarbon-depleted stream and a light paraffin by-product. Benzene and/or toluene from the third stream is then methylated with a methylating agent to produce a xylene-enriched stream.

  • Publication number: 20130296623
    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.

  • Publication number: 20130144097
    Abstract: In a process for producing para-xylene, a naphtha feed is reformed under conditions effective to convert at least 50 wt % of the naphthenes in the naphtha feed to aromatics, but to convert no more than 25 wt % of the paraffins in the naphtha feed, and thereby produce a reforming effluent. A first stream containing benzene and/or toluene is removed from the reforming effluent and is fed to a xylene production unit under conditions effective to convert benzene and/or toluene to xylenes. In addition, a second stream containing C8 aromatics is removed from the reforming effluent and is fed, together with at least part of the xylenes produced in the xylene production unit, to a para-xylene recovery unit to recover a para-xylene product stream and leave a para-xylene-depleted C8 stream.

  • Publication number: 20120149958
    Abstract: The process relates to the use of any naphtha-range stream containing a portion of C8+ aromatics combined with benzene, toluene, and other non-aromatics in the same boiling range to produce toluene. By feeding the A8+ containing stream to a dealkylation/transalkylation/cracking reactor to increase the concentration of toluene in the stream, a more suitable feedstock for the methylation reaction can be produced. This stream can be obtained from a variety of sources, including the pygas stream from a steam cracker, “cat naphtha” from a fluid catalytic cracker, or the heavier portion of reformate.

  • Publication number: 20120036889
    Abstract: A process for converting a gaseous hydrocarbon feed comprising methane to an aromatic hydrocarbon is integrated with liquefied natural gas (LNG) and/or pipeline gas production. In the integrated process, the gaseous hydrocarbon feed is supplied to a conversion zone comprising at least one dehydroaromatization catalyst and is contacted with the catalyst under conversion conditions to produce a gaseous effluent stream comprising at least one aromatic compound, unreacted methane and H2. The gaseous effluent stream is then separated into a first product stream comprising said at least one aromatic compound and a second product stream comprising unreacted methane and H2. The second product stream is further separated into a methane-rich stream and a hydrogen-rich stream and at least part of the methane-rich stream is passed to LNG and/or pipeline gas production.
