Abstract

A multi-function catalyst article for treating both NO and carbon monoxide emissions in a flow of a combustion exhaust gas from a stationary emission source comprises a honeycomb monolith substrate comprising one or more channels which are open at both ends and extend along an axial length thereof and through which, in use, a combustion exhaust gas flows, which catalyst article comprising a catalyst composition comprising a combination of a first, vanadium-containing SCR catalyst component and a second component which is a compound of a transition metal comprising copper, manganese, cobalt, molybdenum, nickel or cerium or a mixture of any two or more thereof and optionally a third, crystalline molecular sieve component.
