Robert W. Grose 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).

  • Novel zeolite compositions and processes for preparing and using same
    Patent number: 4257885
    Abstract: Highly siliceous crystalline zeolitic molecular sieve compositions, having pore diameters of approximately 6 Angstroms, are prepared hydrothermally from reaction mixtures free of organic cations. These novel zeolites can be distinguished from all other zeolites on the basis of certain infrared spectral characteristics and have hydrophobic/organophilic properties which permit their use in selectively adsorbing organic materials from water, either in liquid or in vapor phase.
    Type: Grant
    Filed: August 6, 1979
    Date of Patent: March 24, 1981
    Assignee: Union Carbide Corporation
    Inventors: Robert W. Grose, Edith M. Flanigen
  • Crystalline zeolite Upsilon and process for preparing same
    Patent number: 4211760
    Abstract: A novel zeolitic molecular sieve composition denominated Upsilon is synthesized from aqueous gels in the Na.sub.2 O--Al.sub.2 O.sub.3 --SiO.sub.2 system. The molecular sieve has a pore diameter of about 3.5 Angstroms, a characteristic x-ray diffraction pattern and a composition expressed in moles of oxides as:Na.sub.2 O.Al.sub.2 O.sub.3.2.4-3.4 SiO.sub.2.O-4.5 H.sub.
    Type: Grant
    Filed: March 6, 1979
    Date of Patent: July 8, 1980
    Assignee: Union Carbide Corporation
    Inventors: Robert W. Grose, Edith M. Flanigen
  • Crystalline zeolite phi
    Patent number: 4124686
    Abstract: A novel synthetic crystalline zeolite denominated zeolite "Phi" is prepared hydrothermally from aqueous gels in the [N(CH.sub.3).sub.4 ].sub.2 O - Na.sub.2 O - Al.sub.2 O.sub.3 - SiO.sub.2 system. As synthesized, the zeolite exhibits large-pore adsorption characteristics, a characteristic X-ray powder diffraction pattern and a composition expressed in moles of oxides as: 0.95-1.05 Na.sub.2 0:0.02-0.05 {N(CH.sub.3).sub.4 }.sub.2 O:Al.sub.2 O.sub.3 :4-7 SiO.sub.2 :O-6 H.sub.2 O.
