  • Publication number: 20100120610
    Abstract: A photocatalytic device for reacting with volatile organic compounds includes a photocatalyst and at least one additive, such as hafnium oxide and zirconium oxide, that is capable of forming a stable silicate with silicon dioxide. The additive reacts with volatile silicon-containing compounds to form stable silicate compounds. As a result, the silicon-containing compounds are unavailable for deactivation of the photocatalyst.

  • Publication number: 20100111796
    Abstract: Catalysts, methods of preparing catalyst, and methods for treating exhaust gas streams are described. In one or more embodiments, a catalyst system includes an upstream zone effective to catalyze the conversion of a mixture of NOx and NH3 to N2, and a downstream zone effective for the conversion of ammonia to N2 in the presence or absence of NOx. In an embodiment, a method for preparing a catalyst system includes: first coating one end of a substrate along at least 5% of its length with an undercoat washcoat layer containing a material composition effective to catalyze the removal of ammonia; second coating with an overcoat layer containing a material composition effective to catalyze the conversion of a mixture of NOx and NH3 to N2.

  • Publication number: 20100094070
    Abstract: Bimetallic, supported catalysts for production of 1-hexene from ethylene are manufactured by impregnating a porous, solid support material with at least one catalytic chromium compound and at least one catalytic tantalum compound. The bimetallic, supported catalysts have high catalytic turnover, high selectivity for 1-hexene production, a low tendency for metals to leach from the catalysts during manufacturing and use compared to catalysts manufactured using known techniques. Moreover, the catalysts can be reused in multiple synthesis runs. High turnover, high selectivity, and reusability improve yields and reduce the costs associated with producing 1-hexene from ethylene, while the absence of metal leaching reduces the potential environmental impacts of using toxic metal catalysts (e.g., chromium).
