Abstract[English]
The present disclosure relates to a catalyst system for treating a gas mixture including ozone and volatile organic compounds, the catalyst system being in fluid flow communication with the gas mixture, the catalyst system comprising: a first catalyst comprising at least one platinum group metal, the first catalyst being utilised to predominantly oxidise the volatile organic compounds in the gas mixture; and a second catalyst comprising at least a manganese (Mn) component; the second catalyst being utilised to predominantly reduce the ozone in the gas mixture; wherein the first catalyst and the second catalyst are substantially discrete relative to each other. The present disclosure further relates to a method of treating a gas mixture and to an aircraft environmental control system.[French]
La présente divulgation concerne un système catalyseur pour traiter un mélange gazeux comprenant de l'ozone et des composés organiques volatils, le système catalyseur étant en communication fluidique avec le mélange gazeux, le système catalyseur comprenant : un premier catalyseur contenant au moins un métal du groupe platine, le premier catalyseur étant utilisé principalement pour oxyder les composés organiques volatils dans le mélange gazeux ; et un second catalyseur contenant au moins un composant de manganèse (Mn) ; le second catalyseur étant utilisé principalement pour réduire l'ozone dans le mélange gazeux ; le premier catalyseur et le second catalyseur étant sensiblement distincts l'un de l'autre. La présente divulgation concerne en outre un procédé de traitement d'un mélange gazeux et un système de contrôle environnemental d'un aéronef.
