Abstract
CATALISADOR PARA LIMPEZA DE GÁS DE EXAUSTÃO DE MOTOR DE COMBUSTÃO INTERNA E MÉTODO PARA LIMPEZA DO GÁS DE EXAUSTÃO USANDO O REFERIDO CATALISADOR Trata-se de um processo para remover hidrocarboneto altamente redutor descarregado durante o período de aceleração e para remover de maneira eficaz o hidrocarboneto mesmo após o contato com hidrocarboneto altamente redutor. Com o uso de um catalisador que tem suportada uma proporção maior de paládio com a carga de superfície de valência 2 ou valência 4 do que de valência 0, mediante o suporte de paládio em conjunto com o óxido de magnésio, o hidrocarboneto descarregado a partir de um motor de combustão interna, especialmente, durante o período de aceleração, pode ser removido de maneira eficaz.
