Abstract
um artigo catalisador compreende um catalisador scr e um catalisador de adsorvente de nox, em que cada um desses catalisadores compreende uma peneira molecular de metal, cada uma com um metal diferente. o artigo catalisador pode ser acoplado de forma justa com outros componentes para dar uma vantagem de desempenho de nox a partir do arranque a frio para um sistema combinado doc e scrf. a conversão de nox mais elevada também é mostrada na localização abaixo do chão devido ao armazenamento de nox antes do reaquecimento de scr e controle de deslizamento nh3, permitindo níveis de enchimento nh3 mais elevados. são descritos sistemas compreendendo o artigo catalisador e métodos de utilização do artigo catalisador para dar um controle de hidrocarboneto e monóxido de carbono melhorado, bem como controle de deslizamento de amônia. os sistemas podem incluir monólitos de passagem de fluxo ou de fluxo de parede.
