Abstract

"CATALISADOR DE PURIFICAçãO PARA GáS DE DESCARGA, MéTODO DE PRODUçãO DE UM CATALISADOR PARA GáS DE DESCARGA E APARELHO CATALISADOR DE PURIFICAçãO PARA O GáS DE DESCARGA DE UM AUTOMóVEL". A presente invenção refere-se a um catalisador de purificação para gás de descarga que aperfeiçoa as atividades dos metais preciosos, impedindo a queda das atividades a uma alta temperatura, e exibindo um desempenho suficiente mesmo durante uma operação à baixa temperatura (abaixo de 400<198>C) durante a partida de um veículo ou durante uma marcha lenta do mesmo. O óxido de Pd é suportado sobre o óxido de AI, e o óxido de AI é LnAIO~ 3~(Ln: elemento de terra rara).
