Abstract

FILTRO DE FULIGEM DE DIESEL CATALISADO MELHORADO, PROCESSO PARA A REDUçãO DA TEMPERATURA DE IGNIçãO OU TEMPERATURA DE OXIDAçãO DE FULIGEM DE DIESEL FILTRADA DO GáS DE ESCAPAMENTO DE UM MOTOR DIESEL E CATALISADOR DE FULIGEM DE DIESEL. Um filtro de fuligem de diesel catalisado e processo. O filtro de fuligem de diesel incorpora um elemento de filtro poroso revestido com um agente catalítico tal que fuligem de diesel a partir do gás de escapamento de diesel seja depositada em contato com o agente catalítico quando gás de escapamento de diesel é passado através do elemento de filtro poroso e tal que a temperatura de ignição ou temperatura de oxidação da fuligem de diesel depositada seja reduzida. O agente catalítico é uma mistura de áxidos de metal alcalino e cério. A razão molar de metal alcalino para cério do agente catalítico está na faixa de 0,5 a 5.
