Patent number: 10221742Abstract: 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: GrantFiled: June 23, 2017Date of Patent: March 5, 2019Assignee: Johnson Matthey Public Limited CompanyInventors: Todd Howard Ballinger, Hai-Ying Chen, Julian Peter Cox, Shadab Sharif Mulla, Jeffery Scott Rieck, Erich Conlan Weigert

Patent number: 9968916Abstract: A three-way catalyst is disclosed. The three-way catalyst comprises a silver-containing extruded zeolite substrate and a catalyst layer disposed on the silver-containing extruded zeolite substrate. The catalyst layer comprises a supported platinum group metal catalyst comprising one or more platinum group metals and one or more inorganic oxide carriers. The invention also includes an exhaust system comprising the three-way catalyst. The three-way catalyst results in improved hydrocarbon storage and conversion, in particular during the cold start period.Type: GrantFiled: November 14, 2016Date of Patent: May 15, 2018Assignee: Johnson Matthey Public Limited CompanyInventors: Hsiao-Lan Chang, Hai-Ying Chen, Kwangmo Koo, Jeffery Scott Rieck
