  • Process for producing reformate having increased xylenes content and reduced ethylbenzene content
    Patent number: 7179367
    Abstract: A process for reforming wherein ethylbenzene formed during the reforming is converted to xylenes. The process is carried out by reforming a feed containing precursors of ethylbenzene with a reforming catalyst under conditions effective to reform said feed; wherein the reforming catalyst is contained in a reactor which contains a second catalyst effective under said conditions to convert ethylbenzene to xylenes. The resulting product contains reduced amounts of ethylbenzene and increased amounts of xylenes.
    Type: Grant
    Filed: July 1, 2003
    Date of Patent: February 20, 2007
    Assignee: ExxonMobil Chemical Patents Inc.

  • Process for the production of reformate having reduced ethylbenzene content
    Patent number: 7067052
    Abstract: A process for reforming a hydrocarbon feed containing precursors of ethylbenzene, e.g., C8 isoalkane and/or C8 isoalkene precursors of ethylbenzene, that results in the formation of reduced amounts of ethylbenzene. The process is carried out in a catalytic reforming unit comprised of a plurality of operatively connected reactors comprising at least one lead reforming reactor and a tail reforming reactor. The process is carried out by reforming the feed in at least one lead reactor which contains a first reforming catalyst and a catalyst effective for converting ethylbenzene and further reforming the product of the lead reactor in the tail reactor that contains a second reforming catalyst.
