Abstract

"DISPOSITIVO CATALìTICO, CONVERSOR CATALìTICO E CONVERSOR CATALìTICO-COLETOR DE FULIGEM". A invenção é um dispositivo catalítico compreendido de um suporte de catalisador de grãos de cerâmica fundidos e um catalisador que está superficialmente ligado a pelo menos uma porção dos grãos de cerâmica, incorporados a pelo menos uma porção dos grãos de cerâmica ou combinações destes, sendo que os grãos e o catalisador formam uma estrutura superficial que tem uma dimensão de polígono fractal maior que 1,00 ou a dimensão de polígono tem pelo menos uma mudança de nível, quando medida para um tamanho de polígono fractal "d" de pelo menos 1 micrometro até no máximo 1 milímetro. A invenção é particularmente útil para fazer um conversor catalítico ou um conversor catalítico-coletor de fuligem.
