Patent number: 7635461Abstract: Composite combustion catalyst particles are described and disclosed. A metal core of a combustible metal can be coated with a metal oxide coating. Additionally, a catalyst coating can at least partially surround the metal oxide coating to form a composite catalyst particle. The composite catalyst particles can be dispersed in a variety of fuels such as propulsion fuels and the like to form an enhanced fuel. During initial stages of combustion, the catalyst coating acts to increase combustion of the fuel. As combustion proceeds, the metal core heats sufficiently to disturb the metal oxide coating. The metal core then combusts in highly exothermic reactions with an oxidizer and the catalyst coating to provide improved energy densities to the enhanced fuel.Type: GrantFiled: June 7, 2004Date of Patent: December 22, 2009Assignee: University of Utah Research FoundationInventor: Scott L. Anderson

Publication number: 20090305881Abstract: A method for converting a supported metal nitrate into the corresponding supported metal comprises heating the metal nitrate to effect its decomposition under a gas mixture that contains nitric oxide and has an oxygen content of <5% by volume. The method provides very highly dispersed metal oxide on the support material. The metal oxide is useful as a catalyst or as a catalyst precursor.Type: ApplicationFiled: November 17, 2006Publication date: December 10, 2009Applicant: JOHNSON MATTHEY PLCInventors: Jelle Rudolf Anne Sietsma, Adrianus Jacobus Van Dillen, Petra Elisabeth De Jongh, Krijn Pieter De Jong

Patent number: 7625840Abstract: A nanoporous catalytic membrane which displays several unique features including pores which can go through the entire thickness of the membrane. The membrane has a higher catalytic and product selectivity than conventional catalysts. Anodic aluminum oxide (AAO) membranes serve as the catalyst substrate. This substrate is then subjected to Atomic Layer Deposition (ALD), which allows the controlled narrowing of the pores from 40 nm to 10 nm in the substrate by deposition of a preparatory material. Subsequent deposition of a catalytic layer on the inner surfaces of the pores reduces pore sizes to less than 10 nm and allows for a higher degree of reaction selectivity. The small pore sizes allow control over which molecules enter the pores, and the flow-through feature can allow for partial oxidation of reactant species as opposed to complete oxidation. A nanoporous separation membrane, produced by ALD is also provided for use in gaseous and liquid separations.Type: GrantFiled: September 14, 2004Date of Patent: December 1, 2009Assignee: UChicago Argonne, LLC.Inventors: Michael J. Pellin, John N. Hryn, Jeffrey W. Elam

Patent number: 7601671Abstract: A method for preparing an exhaust gas catalyst includes preparing a washcoat comprising a catalytically effective amount of at least one catalytically active metal disposed upon an oxide support; disposing the catalytically active metal-oxide support washcoat upon a catalyst substrate; drying the washcoated catalyst substrate using microwave energy to affix the precious metals to the oxide support; and conventionally calcining the dried washcoated catalyst substrate. The catalysts comprising a substrate having dispersed thereon an inorganic oxide washcoat, the washcoat having been affixed to the substrate by microwave drying, exhibit high exhaust gas purifying performance and long durability. The catalysts thus produced further provide a long in-service lifetime for reforming organic fuel species into hydrogen, carbon monoxide and light hydrocarbons used in the nitrogen oxides reduction process.Type: GrantFiled: October 28, 2004Date of Patent: October 13, 2009Assignee: Umicore AG & Co.
