  • Patent number: 9084987
    Abstract: The invention relates to a process to produce catalysts by powder injection molding and the catalysts thereof, wherein the catalysts are made by preparing a ceramic formulation with temperature controlled rheological properties comprising catalytic components, heating the powder formulation up to at least the fluid state transition temperature, shaping a sample by injecting the fluid powder formulation into an injection mold followed by cooling the injected powder formulation below the fluid state transition temperature, de-binding the shaped sample, and sintering the shaped sample to form a ceramic catalyst. Alternatively the ceramic structure may be formed initially followed by a coating of the ceramic structure by one or more catalytic compounds.
    Type: Grant

    Date of Patent: July 21, 2015
    Assignee: YARA INTERNATIONAL ASA
    Inventors: David Waller, David M. Brackenbury
  • Patent number: 8562926
    Abstract: A method and device for catchment of platinum group metals (PGM) in a gaseous steam, where the method comprises using a catalyst comprising a porous ceramic body in which at least a part of the surface area is covered by one or more PGM-catching metal(s)/alloy(s), and where the device comprises the porous ceramic body in which at least a part of the surface area is covered by one or more PGM-catching metal(s)/alloy(s). In a further aspect, the invention also relates to a method for producing the inventive device.
