  • Aromatic transalkylation using a modified LZ-210 zeolite
    Patent number: 7700511
    Abstract: A process for converting polyalkylaromatics to monoalkylaromatics, particularly cumene, in the presence of a modified LZ-210 zeolite catalyst is disclosed. The process attains greater selectivity, reduced formation of undesired byproducts, and increased activity.
    Type: Grant
    Filed: March 11, 2009
    Date of Patent: April 20, 2010
    Assignee: UOP LLC
    Inventors: Thomas M. Reynolds, Christopher J. Garrett, Deng-Yang Jan, Robert J. Schmidt, Mathias P. Koljack

  • Modified Y-85 and LZ-210 Zeolites
    Publication number: 20080171649
    Abstract: Catalysts for converting polyalkylaiomatics to monoalkylaromatics, particularly cumene and ethyl benzene are disclosed which comprise modified Y-85 or LZ-210 zeolites. For cumene and ethylbenzene production, a disclosed catalyst, made of 80 wt % zeolite and 20 wt % alumina binder on a volatile-flee basis, has one or more of the following physical characteristics: (1) an absolute intensity of the modified Y zeolite as measured by X-ray diffraction (XRD) of preferably at least 50 and (2) a framework aluminum of the modified Y zeolite of preferably at least 50% of the aluminum of the modified Y zeolite.
