  • US Patent:
    7576026, Aug 18, 2009
  • Filed:
    Sep 19, 2007
  • Appl. No.:
    11/857728

  • Assignee:
    Saudi Basic Industries Corporation - Riyadh
  • International Classification:
    B01J 29/06
    B01J 29/40
  • US Classification:
    502 77, 502 60
  • Abstract:
    A method of treating a ZSM-5-type zeolite catalyst is carried out by treating a ZSM-5 zeolite catalyst having a silica/alumina mole ratio of at least about 200 with a phosphorus compound. The phosphorus-treated ZSM-5 zeolite catalyst is calcined and steamed. Steaming of the catalyst is carried out at a temperature of less than about 300 C. The phosphorus-treated ZSM-5 zeolite catalyst has less than 0. 05% by weight of the catalyst of any other element other than phosphorus provided from any treatment of the ZSM-5 zeolite with a compound containing said other element. The catalyst may be used in aromatic alkylation by contacting the catalyst with feed of an aromatic hydrocarbon and an alkylating agent within a reactor under reactor conditions suitable for aromatic alkylation. Water cofeed may be introduced water into the reactor during the aromatic alkylation reaction.
