  • Oligomerization Using Molecular Sieve Catalysts
    Publication number: 20080293991
    Abstract: Treatment with steam, especially at sub-atmospheric pressure, rejuvenates deactivated zeolites that have been used as catalysts for liquid phase or dense phase oligomerization.
    Type: Application
    Filed: May 26, 2006
    Publication date: November 27, 2008
    Inventors: Jihad M. Dakka, Hans K.T. Goris
  • Oligomerization process
    Patent number: 7414165
    Abstract: In a process for oligomerizing an olefinic hydrocarbon feedstock comprising sulfur-containing molecules, the feedstock is contacted in the absence of hydrogen with a first metal oxide catalyst at a temperature in excess of 150° C. and then is contacted under olefin oligomerization conditions with a second catalyst comprising a crystalline molecular sieve, such as ZSM-22 or ZSM-57.
    Type: Grant
    Filed: June 29, 2007
    Date of Patent: August 19, 2008
    Assignee: ExxonMobil Chemical Patents Inc.
    Inventors: Jihad Mohammed Dakka, Hans K. T. Goris, Georges M. K. Mathys, Stephen Harold Brown, Bruce R. Cook
