Abstract

um catalisador de três vias é divulgado. o catalisador de três vias compreende um componente de paládio compreendendo paládio e um óxido de compósito ou misto de céria-zircônia-alumina, e também compreende um componente de ródio compreendendo ródio e um material que contém zircônia. o componente de paládio e o componente de ródio são revestidos para um substrato de peneira molecular extrusada que contém prata. a invenção também inclui um sistema de exaustão compreendendo o catalisador de três vias. o catalisador de três vias resulta em conversão e armazenamento de hidrocarbonetoeto aprimorado, em particular durante o período de partida a frio.
