  • Publication number: 20080045768
    Abstract: This disclosure relates to a crystalline MCM-22 family molecular sieve composition having, in its as-synthesized form, an X-ray diffraction pattern including a peak at d-spacing maximum of 12.33±0.23 Angstroms, a distinguishable peak at a d-spacing maximum between 12.57 to about 14.17 Angstroms and a non-discrete peak at a d-spacing maximum between 8.8 to 11. Angstroms, wherein the peak intensity of the d-spacing maximum between 12.57 to about 14.17 Angstroms is less than 90% of the peak intensity of the d-spacing maximum at 12.33±0.23 Angstroms. This disclosure also relates to methods of making the crystalline MCM-22 family molecular sieve composition.

  • Publication number: 20080027256
    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.
