Title (EN) METHOD OF MANUFACTURING A CATALYTIC CONVERTER AND AFTER-TREATING APPARATUS OF EXHAUST GAS USING THE CATALYTIC CONVERTER
(FR) PROCEDE DE FABRICATION D'UN CONVERTISSEUR CATALYTIQUE ET APPAREIL DE TRAITEMENT ULTERIEUR DE GAZ D'ECHAPPEMENT AU MOYEN DUDIT CONVERTISSEUR CATALYTIQUE
Abstract:
(EN) An after-treating apparatus of exhaust gas and a catalyst converter installed therein is disclosed. The after-treating apparatus of exhaust gas primarily removes the exhaust gas in a first filtering device and a second filtering device, and secondarily purifies within the catalyst converter. The first filtering device and the second filtering device are controlled by opening and closing a valve through a time control part. That is, when particulate of the exhaust gas is collected in the first filtering device, the second filtering device burns the collected particulate by means of an electric heater. Further, the catalytic converter is prepared by coating a honeycomb supported on a supporter of alumina (Al2O3) and chromic oxide (Cr2O3) with a composite consisting of platinum, nickel and a promoter metal, or serially combining a honeycomb (a) and a honeycomb (b) in the order of (a) + (b) or (b) + (a). The honeycomb (a) is supported on a supporter of alumina (Al2O3) and coated with a composite consisting of platinum and nickel and a promoter metal. The honeycomb (b) is supported on a supporter of chromic oxide (Cr2O3) and coated with a composite consisting of platinum, nickel, and a promoter metal. Only the catalytic converters prepared by the above-stated method are used for treating exhaust gas.
(FR) L'invention concerne un appareil de traitement ultérieur de gaz d'échappement et un convertisseur catalytique installé dans ce dernier. L'appareil de traitement ultérieur de gaz d'échappement, envoie d'abord le gaz d'échappement dans un premier et un deuxième dispositif de filtrage, après quoi il le purifie dans le convertisseur catalytique. Les premier et deuxième dispositifs de filtrage sont commandés par l'ouverture et la fermeture d'une soupape au moyen d'une pièce de commande à minuterie. Lorsque la substance particulaire du gaz d'échappement est collectée dans le premier dispositif de filtrage, le deuxième dispositif de filtrage brûle la substance particulaire collectée, au moyen d'un organe de chauffage électrique. Par ailleurs, le convertisseur catalytique est produit par enduction d'une structure alvéolaire supportée par un support en alumine (Al2O3) et oxyde de chrome, d'un composite formé de platine, de nickel et d'un métal promoteur, ou par combinaison en série d'une structure alvéolaire (a) et d'une structure alvéolaire (b), dans l'ordre (a) + (b) ou (b) + (a). La structure alvéolaire (a) est supportée par un support en alumine (AL2O3) et est revêtue d'un composite formé de platine et de nickel ainsi que d'un métal promoteur. La structure alvéolaire (b) est supportée par un support en oxyde de chrome (Cr2O3) et est revêtue d'un composite constitué de platine, de nickel et d'un métal promoteur. Seuls les convertisseurs catalytiques préparés selon le procédé de l'invention sont utilisés pour le traitement des gaz d'échappement.
