  • Alkylation reactor design with effluent recycle and impure benzene regeneration
    Patent number: 7652181
    Abstract: An improved alkylation reactor design is disclosed. The design uses reactor effluent recycle to reduce the difference in temperature across the reaction zone improving selectivity and insuring the maintenance of a liquid phase in the reactor.
    Type: Grant
    Filed: May 2, 2006
    Date of Patent: January 26, 2010
    Assignee: UOP LLC

  • Process for the high yield production of monoalkylaromatics
    Patent number: 7622622
    Abstract: Disclosed is a process and apparatus for alkylating light olefin with benzene at near but less than full conversion of the olefin. We have found that stopping below full conversion of the olefin maximizes yield of monoalkylbenzene.

  • Aromatic Transalkylation Using a Y-85 Zeolite
    Publication number: 20080171902
    Abstract: A process for converting polyalkylaromatics to monoalkylaromatics, particulary cumene, in the presence of a modified Y-85 zeolite is disclosed. The process attains greater selectivity, reduced formation of undesired byproducts, and increased activity.
