  • Publication number: 20190022628
    Abstract: The present disclosure is directed to the preparation of silver-based HSCs. During preparation of the catalyst a selected carrier is co-impregnated with a solution containing a catalytically effective amount of silver and a promoting amount of rhenium and other promoters. After co-impregnation, the carrier is subjected to a separate heat treatment prior to calcination. Such heat treatment is conducted for between about 1 minute and about 120 minutes at temperatures between about 40° C. and about 300° C. Catalysts prepared by the present methodology evidence improved selectivity, activity and/or stability resulting in an increase in the useful life of the catalyst.

  • Publication number: 20070237676
    Abstract: A micro-cantilever includes a base, a micro-cantilever beam and a tip. The micro-cantilever beam extends outwardly from the base and is constructed from a material including a thermoplastic polymer material. The micro-cantilever beam has a distal end opposite the base. The tip extends transversely from the distal end. The tip is constructed from a material including a thermoplastic polymer material and is integrated with the micro-cantilever beam. To make a micro-cantilever, a mold defining a cavity having a geometry of a micro-cantilever is formed and an indentation corresponding to an image of a probe tip is formed in the mold. Molten thermoplastic is injected into the mold.

  • Publication number: 20060054017
    Abstract: A circumferential slot virtual impactor includes a disk-shaped housing with an endless circumferential slot for receiving aerosols. The slot forms an acceleration nozzle, and a receiver nozzle spaced apart radially inwardly from the acceleration nozzle exit. In an annular gap between the two nozzles, negative pressure is selectively applied to draw a major flow of the aerosol axially away from the nozzles, while a minor flow of the aerosol is drawn radially inward and enters the receiver nozzle. A portion of the larger particles leaves the major flow and merges with the minor flow due to particle momentum, thus increasing the large-particle concentration of the minor flow. The acceleration nozzle incorporates convex curvature along its opposed interior surfaces, for a smoother aerosol flow and reduced large-particle deposition.

  • Patent number: 6559094
    Abstract: The invention pertains to the preparation and use of catalytic materials and catalyst members for the selective oxidation of carbon monoxide in a gas stream that contains hydrogen. One such catalyst member may be produced by depositing by electric arc spraying a metal feedstock onto a metal substrate to provide a metal anchor layer on the substrate, and depositing a catalytic material comprising platinum and iron dispersed on a refractory inorganic oxide support material onto the metal substrate. The catalytic material may optionally be produced by wetting the support material, especially a particulate support material, with a platinum group metal solution and iron solution and drying and calcining the wetted support material in air at a temperature in the range of from 200° C. to 300° C., preferably using a solution containing bivalent platinum ion species. The catalyst member may be used by flowing the gas stream therethrough at a temperature at about 90° C.
