Abstract

trata-se de uma composição de catalisador para evitar a desativação de um catalisador de purificação de gás de escape para um sistema de combustão de gás natural comprimido, carregado com componentes de metais nobres que contêm platina e paládio. em um catalisador de oxidação de gás de escape para um veículo ou sistema de combustão de gás natural comprimido em que primeira alumina impregnada de platina, segunda alumina impregnada de paládio e um componente de céria estão carregados em um apoio de cerâmica, sendo que a primeira alumina é adicionalmente impregnada com um cocatalisador de bário evitando significativamente, dessa forma, a desativação de um catalisador de motor de queima pobre de cng.
