  • Aromatic conversion processes and zeolite catalyst useful therein
    Patent number: 6864203
    Abstract: A process is provided for the alkylation, transalkylation, or isomerization of aromatic hydrocarbons. The processes comprises contacting aromatic hydrocarbons under conversion conditions with a zeolite bound zeolite catalyst. The zeolite bound zeolite catalyst comprises first crystals of a first large pore zeolite which are bound together by second crystals of a second zeolite.
    Type: Grant
    Filed: February 28, 2002
    Date of Patent: March 8, 2005
    Assignee: ExxonMobil Chemical Patents Inc.
    Inventors: Dan Eldon Hendriksen, Gary David Mohr, Johannes Petrus Verduijn, Robert Scott Smith

  • Alkylation process using zeolite beta
    Patent number: 6002057
    Abstract: A process for the alkylation of an aromatic compound with C.sub.2 to C.sub.4 olefin alkylating agent. A process to produce ethylbenzene by reaction of ethylene in stoichiometric or excess amount with benzene in the presence of a zeolite beta catalyst. This process is especially suitable for reaction of dilute ethylene with dilute benzene in a catalytic distillation column.
