Abstract

COMPOSIçõES NãO TECIDAS E PRODUTOS E MéTODOS RELACIONADOS. A presente invenção, em eterminadas modalidades, está voltada para um substrato catalítico, apropriado para uso em diversas aplicações, inclusive como substrato em um conversor catalítico. Ouro aspecto da présente invenção é um substrato de filtração, apropriado para uso diversas aplicações, inclusive como substrato em um filtro de partículas, tal como um filtro de partículas de diesel (DPF) ou coletor de partículas de diesel (DPT). A invenção também põe á disposição um substrato aperfeiçoado para remover e/ou eliminar poluentes do escamento de motores de combustão. O substrato catalítico e substrato de filtração oferecem, em determinadas modalidades, aperfeiçoamentos na remoção de poluentes de um gás de escapamento. Os aperfeiçoamentos incluem um ou mais dos seguintes: período de light-off mais rápido, filtração profunda de PM, menos contracorrente, menor probabilidade de obstrução, aptidão para ser colocado em múltiplos lugares no sistema de escapamento, inclusive no tubo de escapamento ou na própria cabeça, alta probabilidade de reação catalítica, altas proporções de conversão de NOx, HC e CO, uma queima mais rápida de PM, minimização do uso de material de catalisador e similar.
