  • Three-way catalyst having an upstream single-layer catalyst
    Patent number: 8557204
    Abstract: Disclosed herein is a layered, three-way conversion catalyst having the capability of simultaneously catalyzing the oxidation of hydrocarbons and carbon monoxide and the reduction of nitrogen oxides being separated in a front and rear portion is disclosed. Provided is a catalytic composite material of a single front and two rear layers in conjunction with a substrate, where each of the layers includes a support, all layers comprise a platinum group metal component, and the rear bottom layer is substantially free of an oxygen storage component (OSC).
    Type: Grant
    Filed: November 22, 2010
    Date of Patent: October 15, 2013
    Assignee: Umicore AG & Co. KG
    Inventors: John G. Nunan, Raoul Klingmann, Ryan Andersen, Davion Clark, David H. Moser
  • Three-way catalyst having a upstream multi-layer catalyst
    Patent number: 8394348
    Abstract: Disclosed herein is a layered, three-way conversion catalyst having the capability of simultaneously catalyzing the oxidation of hydrocarbons and carbon monoxide and the reduction of nitrogen oxides being separated in a front and rear portion is disclosed. Provided is a catalytic material of at least two front and two rear layers in conjunction with a substrate, where each of the layers includes a support, all layers comprise a platinum group metal component, and the rear bottom layer is substantially free of a ceria-containing oxygen storage component (OSC).
