A method for catalytically cleaning an exhaust gas, including receiving the exhaust gas in an inlet channel, blocking the exhaust gas in the inlet channel, diffusing the exhaust gas through a porous substantially fibrous nonwoven wall of the inlet channel, reacting the exhaust gas with at least one catalyst material to at least partially remove nitrous oxides, hydrocarbons and carbon monoxide therefrom, the at least one catalyst material being disposed on the porous wall, trapping particulate matter in the porous substantially fibrous nonwoven wall, receiving the diffused exhaust gas into an outlet channel, and transitioning the exhaust gas from the outlet channel to the atmosphere.
La présente invention concerne un procédé permettant de nettoyer par catalyse un gaz d~échappement, consistant à recevoir le gaz d~échappement dans un canal d~admission, à bloquer le gaz d~échappement dans le canal d~admission, à diffuser le gaz d~échappement à travers une paroi poreuse, substantiellement fibreuse et non tissée du canal d~admission, à faire réagir le gaz d~échappement avec au moins un matériau catalyseur afin d~en retirer, au moins en partie, les oxydes nitreux, les hydrocarbures et le monoxyde de carbone, le ou les matériaux catalyseurs étant disposés sur la paroi poreuse, à capturer la matière sous forme de particules dans la paroi poreuse, substantiellement fibreuse et non tissée, à recevoir le gaz d~échappement diffusé dans un canal d~évacuation et enfin à transférer le gaz d~échappement du canal d~évacuation dans l~atmosphère.
