  • Patent number: 8529752
    Abstract: This invention relates to a process for hydrocarbon conversion comprising contacting a hydrocarbon feedstock with a crystalline molecular sieve, in its ammonium exchanged form or in its calcined form, under conversion conditions to form a conversion product, said crystalline molecular sieve comprising unit cells with MWW topology and is characterized by diffraction streaking from the unit cell arrangement in the c direction as evidenced by the arced hk0 patterns of electron diffraction pattern.
    Type: Grant
    Filed: December 15, 2011
    Date of Patent: September 10, 2013
    Assignee: ExxonMobil Chemical Patents Inc.
    Inventors: Wieslaw J. Roth, Thomas Yorke, Douglas Lewis Dorset, Mohan Kalyanaraman, Michael Charles Kerby, Simon Christopher Weston

  • Patent number: 8110176
    Abstract: This invention relates to a crystalline molecular sieve, in its ammonium exchanged form or in its calcined form, comprising unit cells with MWW topology, said crystalline molecular sieve is characterized by diffraction streaking from the unit cell arrangement in the c direction. The crystalline molecular sieve is further characterized by the arced hk0 patterns of electron diffraction pattern. The crystalline molecular sieve is further characterized by the unit cells streaking along c direction. This invention also relates to a method of making thereof.
