Abstract

certos artigos, sistemas e métodos de redução catalítica seletiva (scr) fornecem alta conversão de nox e, ao mesmo tempo, baixa formação de n2o. os artigos, sistemas e métodos são adequados, por exemplo, para o tratamento de gases de exaustão de motores diesel. certos artigos têm revestimentos zoneados dispostos sobre os mesmos, por exemplo, um revestimento zoneado compreendendo uma zona a montante compreendendo uma camada de revestimento que compreende uma peneira molecular contendo ferro ativada por vapor e uma zona a jusante compreendendo uma camada de revestimento que compreende um peneira molecular contendo um elevado teor de cobre.
