Kenneth G. Simmons has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 5364999
    Abstract: There is provided a process for converting organic compounds using a catalyst comprising a pillared, layered crystalline oxide material. This material may be prepared by intercepting a swellable layered oxide before calcination. The intercepted material is swollen and pillared. If the material is not intercepted in this manner, it is transformed into a zeolite by calcination. The pillared material may have a large degree of catalytic activity, and it may have rather porous layers.
    Type: Grant
    Filed: March 9, 1993
    Date of Patent: November 15, 1994
    Assignee: Mobil Oil Corp.
    Inventors: Charles T. Kresge, Wieslaw J. Roth, Kenneth G. Simmons, James C. Vartuli
  • Patent number: 5292698
    Abstract: There is provided a catalyst comprising MCM-36 and a binder material.
    Type: Grant
    Filed: August 12, 1992
    Date of Patent: March 8, 1994
    Assignee: Mobil Oil Corp.

  • Patent number: 5250277
    Abstract: There is provided a crystalline oxide material with a characteristic X-ray diffraction pattern. This material may be a layered material, which is swollen or pillared. Upon calcination of the swollen material, the layers collapse and condense upon one another in a somewhat disordered fashion to form a non-swellable material. However, the swollen layered material may be intercalated with polymeric oxide pillars to maintain layer separation, even after calcination.

  • Patent number: 5229341
    Abstract: There is provided a pillared, layered crystalline oxide material and a method for making this material. This material may be prepared by intercepting a swellable layered oxide before calcination. The intercepted material is swollen and pillared. If the material is not intercepted in this manner, it is transformed into a zeolite by calcination. The pillared material may have a large degree of catalytic activity, and it may have rather porous layers.

  • Patent number: 5215737
    Abstract: There is provided a method for synthesizing a new synthetic composition of ultra-large pore crystalline material which can be used as a sorbent or catalyst component for conversion of organic and inorganic compounds. The crystalline material product of this method exhibits unusually large sorption capacity demonstrated by its benzene adsorption capacity of greater than about 15 grams benzene/100 grams at 50 torr and 25.degree. C. This material may have a hexagonal electron diffraction pattern that can be indexed with a d.sub.100 value greater than about 18 Angstrom Units and a hexagonal arrangement of uniformly sized pores with a maximum perpendicular cross section of a least about 13 Angstrom units. The reaction mixture for preparing this material contains silica-alumina hydrogel.

  • Patent number: 5068216
    Abstract: There is provided a method for pillaring a layered silicate, such as kenyaite, with polymeric oxide by using a single step treatment with a mixture of swelling agent and pillar precursor. The swelling agent may be an organic cation, such as a cetyltrimethylammonium cation, and the pillar precursor may be a compound which is capable of hydrolyzing to form a polymeric oxide. Tetraethylorthosilicate is an example of such a pillar precursor.
