  • Catalyst containing microporous zeolite in mesoporous support
    Patent number: 6762143
    Abstract: A catalytic material includes a microporous zeolite supported on a mesoporous inorganic oxide support. The microporous zeolite can include zeolite beta, zeolite Y or ZSM-5. The mesoporous inorganic oxide can be, e.g., silica or alumina, and can optionally include other metals. Methods for making and using the catalytic material are described herein.

  • Mesoporous material with active metals
    Publication number: 20030188991
    Abstract: A process for treating organic compounds includes providing a composition which includes a substantially mesoporous structure of silica containing at least 97% by volume of pores having a pore size ranging from about 15 Å to about 30 Å and having a micropore volume of at least about 0.01 cc/g, wherein the mesoporous structure has incorporated therewith at least about 0.02% by weight of at least one catalytically and/or chemically active heteroatom selected from the group consisting of Al, Ti, V, Cr, Zn, Fe, Sn, Mo, Ga, Ni, Co, In, Zr, Mn, Cu, Mg, Pd, Pt and W, and the catalyst has an X-ray diffraction pattern with one peak at 0.3° to about 3.5° at 2&thgr;.

  • Mesoporous material and use thereof for the selective oxidation of organic compounds
    Publication number: 20030017943
    Abstract: A material especially useful for the selective oxidation of hydrocarbons and other organic compounds includes a non-crystalline, porous inorganic oxide having at least 97 volume percent mesopores based on micropores and mesopores, and at least one catalytically active metal selected from the group consisting of one or more transition metal and one or more noble metal.

  • Inorganic oxides with mesoporosity or combined meso-and microporosity and process for the preparation thereof
    Patent number: 6358486
    Abstract: Bimodal amporphous inorganic material that in a pore size distribution plot has distinct mesopore and micropore peaks. A process for producing a bimodal material or a material that contains essentially only mesopores involves heating an inorganic oxide in the presence of material that bonds to the inorganic oxide by hydrogen bonding.
