  • Publication number: 20080070778
    Abstract: Catalysts, systems and methods are described to reduce NOx emissions of an internal combustion engine. In one embodiment, an emissions treatment system for an exhaust stream is provided having a catalyst comprising silver and a platinum group metal on a particulate alumina support, the atomic fraction of the platinum group metal being less than or equal to about 0.25. Methods of manufacturing catalysts are described in which silver is impregnated on alumina particles.

  • Patent number: 6949267
    Abstract: Methods are disclosed for providing a library of composite compositions on a support. The method involves depositing one or more components onto the support on either discrete spaced regions of the support or as a continuous concentration gradients on the surface of the support. The composite samples can be removed from the support by drilling out portions of the coated support so as to yield individual composite tablets containing the support with one or more component layers thereon. By using this method, a vast number of composites can be made and tested simultaneously.

  • Publication number: 20040028815
    Abstract: Methods are disclosed for providing a library of composite or novel composition samples on a support. The method involves depositing one or more components as concentration gradients on the surface of the support. The concentration gradients are placed on the support in the form of superimposed triangles which allow ready formation of composite or composition samples containing three or more components. The samples can be removed from the support by drilling out portions of the coated support so as to yield individual tablets containing the support with one or more component layers thereon. By using this method, a vast number of samples can be made.

  • Patent number: 6375905
    Abstract: A metal substrate is fabricated and coated with a catalyst for ozone conversion of atmosphere passing through the substrate. A plurality of aluminum foil sheets that have been slit, stretched and twisted into a plurality of regularly repeating channels having geometrically shaped openings are serially positioned one on top the other to form a foil stack with channel openings partially blocked by channel walls of overlying foil sheets. Thicker covers with openings at the top and bottom of the stack form a sandwich and the sandwich pleated to form corrugations in a flexible but rigid sandwich substrate. The channel walls are coated with an ozone depleting catalyst which the ozone atmosphere contacts to remove ozone as the ozone atmosphere travels through the stack construction.

  • Patent number: 5942207
    Abstract: This invention relates to zeolitic molecular sieve compositions characterized by outstanding capability to complex multivalent cations, especially calcium. In particular, the invention relates to novel zeolitic molecular sieve compositions, having a high alumina-to-silica ratio, with additional occluded non-zeolitic silicate, and solid particulate alumina is the source of alumina in the zeolite.
