摘要： A homogeneous ceria-based mixed-metal oxide, useful as a catalyst support, a co-catalyst and/or a getter has a relatively large surface area per weight, typically exceeding 150 m2/g, a structure of nanocrystallites having diameters of less than 4 nm, and including pores larger than the nanocrystallites and having diameters in the range of 4 to about 9 nm. The ratio of pore volumes, VP, to skeletal structure volumes, VS, is typically less than about 2.5, and the surface area per unit volume of the oxide material is greater than 320 m2/cm3, for low internal mass transfer resistance and large effective surface area for reaction activity. The mixed metal oxide is ceria-based, includes Zr and or Hf, and is made by a novel co-precipitation process. A highly dispersed catalyst metal, typically a noble metal such as Pt, may be loaded on to the mixed metal oxide support from a catalyst metal-containing solution following a selected acid surface treatment of the oxide support. Appropriate ratioing of the Ce and other metal constituents of the oxide support contribute to it retaining in a cubic phase and enhancing catalytic performance. Rhenium is preferably further loaded on to the mixed-metal oxide support and passivated, to increase the activity of the catalyst. The metal-loaded mixed-metal oxide catalyst is applied particularly in water gas shift reactions as associated with fuel processing systems, as for fuel cells.

摘要： A method and apparatus are provided for quantifying molybdate corrosion inhibitor concentrations in lithium halide brines of absorption refrigeration systems. This permits monitoring and control of the inhibitor level. A reagent is chosen for reacting with the molybdate in the brine to provide a readily identifiable characteristic color, the intensity of which is a function and measure of the molybdate concentration. The reagent is an acidified reducing agent which reacts to provide a significant characteristic color capable of optical detection without interference. In a lithium bromide brine, the molybdate concentration is conveniently identified by reaction with stannous chloride SnCl in hydrochloric acid Hcl (). The resulting color corresponds to a wavelength of about 550-560 nm (pink), and the intensity is a function of molybdate concentration. Portable measuring equipment, such as a hand held spectrophotometer, or colorimeter, provide a convenient means for making on-site measurements.

摘要： A method of surface refinement for refining a first roughness of a surface of a component to a second roughness. The method includes wetting the first roughness surface with an aqueous mixture that includes solid media. The aqueous mixture chemically alters the surface forming a chemically converted surface. Relative movement between the chemically converted surface and the solid media produces the refined second roughness.

摘要： A fuel processing method is operable to remove substantially all of the sulfur present in an undiluted oxygenated hydrocarbon fuel stock supply which contains an oxygenate and which is used to power an internal combustion engine in a mobile environment, such as an automobile, bus, truck, boat, or the like, or in a stationary environment. The fuel stock can be gasoline, diesel fuel, or other like fuels which contain relatively high levels of organic sulfur compounds such as mercaptans, sulfides, disulfides, and the like. The undiluted hydrocarbon fuel supply is passed through a nickel reactant desulfurizer bed wherein essentially all of the sulfur in the organic sulfur compounds reacts with the nickel reactant, and is converted to nickel sulfide, while the desulfurized organic remnants continue through the remainder of the fuel processing system. The method can be used to desulfurize either a liquid or a gaseous fuel stream, which contains an oxygenate such as MTBE, ethanol, methanol, or the like. The inclusion of the oxygenate serves to extend the useful life of the desulfurization apparatus and method.
