  • Three-way catalyst having an upstream single-layer catalyst
    Patent number: 8968690
    Abstract: Disclosed herein is a layered three-way catalytic system being separated in a front and a rear portion having the capability of simultaneously catalyzing the oxidation of hydrocarbons and carbon monoxide and the reduction of nitrogen oxides. Provided is a catalyst composite comprising a single front catalytic layer and two rear catalytic layers in conjunction with a substrate, where the single font layer and the rear bottom layer comprise a Pd component, the rear top layer comprises a Rh component, and the rear bottom layer is substantially free of an oxygen storage component (OSC).
    Type: Grant
    Filed: November 21, 2011
    Date of Patent: March 3, 2015
    Assignee: Umicore AG & Co. KG
    Inventors: John G. Nunan, Raoul Klingmann, Ryan J. Andersen, Davion Onuga Clark, David Henry Moser
