Publication number: 20100137666Abstract: A catalyst for aromatizing a lower hydrocarbon, in order to increase the amount of production of useful aromatic compounds, such as benzene and toluene, by improving the methane conversion rate, the benzene formation rate, the naphthalene formation rate and the BTX formation rate (or a total formation rate of benzene, toluene and xylene) is such that molybdenum and silver are loaded on a metallosilicate as a substrate. It is more preferable to obtain the aromatizing catalyst by loading molybdenum and silver after modifying a zeolite formed of the metallosilicate with a silane compound that has a molecular diameter larger than a pore diameter of the zeolite and that has an amino group, which selectively reacts at a Bronsted acid point of the zeolite, and a straight-chain hydrocarbon group.Type: ApplicationFiled: March 28, 2008Publication date: June 3, 2010Inventors: Shinichi Yamada, Tomohiro Yamada, Yuji Ogawa, Takuya Hatagishi, Yo Yamamoto, Yoshio Sugiyama

Publication number: 20100120611Abstract: The invention relates to catalytically active components for thermal ionization detectors for the detection of compounds containing halogen which have an improved structure as well as to a manufacturing method for an oxide ceramic sintering material for the components. It is the object of the invention to manufacture catalytically active components for thermal ionization detectors for gas chromatographic applications which are thermally, mechanically and chemically stable in the long term and which have increased sensitivity to the materials to be detected. In this respect, the sintering material should be adjustable in a controllable manner in the ideal parameter required for the detector. It is proposed in accordance with the invention to use an oxide ceramic sintering material for the components which comprises a crystalline phase and an amorphous glass phase, with it being essential to the invention that the amorphous glass phase is formed with 0.1 to 20% by weight of a cesium compound.Type: ApplicationFiled: July 30, 2007Publication date: May 13, 2010Applicant: FRAUNHOFER-GESELLSCHAFT ZUR FORDERUNG DER ANGEWANDTEN FORSCHUNG E.V.Inventors: Viktar Sauchuk, Peter Otschik, Klaus Eichler, Mihails Kusnezoff

Patent number: 7709410Abstract: The invention relates to Group 1 metal/silica gel compositions comprising silica gel and an alkali metal or an alkali metal alloy. The compositions of the inventions are described as Stage 0, I, II, and III materials. These materials differ in their preparation and chemical reactivity. Each successive stage may be prepared directly using the methods described below or from an earlier stage material. Stage 0 materials may, for example, be prepared using liquid alloys of Na and K which are rapidly absorbed by silica gel (porous SiO2) under isothermal conditions, preferably at or just above room temperature, to form loose black powders that retain much of the reducing ability of the parent metals. When the low melting Group 1 metals are absorbed into the silica gel, a mild exothermic reaction produces Stage I material, loose black powders that are indefinitely stable in dry air. Subsequent heating to 400° C. produces Stage II materials, which are also loose black powders. Further heating above 400° C.Type: GrantFiled: August 11, 2008Date of Patent: May 4, 2010Assignee: SiGNa Chemistry, Inc.Inventors: Michael Lefenfeld, James L. Dye

Publication number: 20100074974Abstract: A modified sol-gel method to create metal-rich siliceous material, such as colloidal silica or aluminosilicate particles is disclosed. Initially, the metal salt of choice is added to a silicic acid solution or a silicic acid solution containing aluminum salt. The aluminum is added to vary the metal-support interaction as it forms Al—O—Si linkages within the silica matrix. Besides aluminum, other metals can be added that form M—O—Si (M=Ti, B, etc.) linkages, which do not become reduced when treated with a reducing agent. Once the metal, silicic acid and/or aluminum salt is generated, it is subjected to colloidal growth by addition to a basic heel. Upon colloidal synthesis, the metal salt containing colloidal particle is left as is to maximize colloidal stability or is reduced with hydrazine to produce the zero valence metal-containing colloidal particle.Type: ApplicationFiled: December 1, 2009Publication date: March 25, 2010Inventor: Brian T.
