  • CO slip catalyst and method of using
    Patent number: 10221742
    Abstract: A CO slip catalyst, for treating an exhaust gas from a lean burn internal combustion engine, is disclosed. The CO slip catalyst comprises palladium and a ceria-containing material. The invention also includes a method for oxidizing excess CO in an exhaust gas, wherein the excess CO results from the periodic contact of an upstream catalyst under rich exhaust conditions. The method comprises contacting the excess CO in the exhaust gas with a CO slip catalyst at a temperature in the range of 100 to 700° C.
    Type: Grant
    Filed: June 23, 2017
    Date of Patent: March 5, 2019
    Assignee: Johnson Matthey Public Limited Company
    Inventors: Todd Howard Ballinger, Hai-Ying Chen, Julian Peter Cox, Shadab Sharif Mulla, Jeffery Scott Rieck, Erich Conlan Weigert
