Title (EN) METHOD AND APPARATUS FOR REDUCING NOX WITH FIRST AND SECOND CATALYSIS
(FR) PROCEDE ET APPAREIL DE REDUCTION DES NOX PAR UNE PREMIERE ET UNE SECONDE CATALYSES
Abstract: front page image
(EN)A method and apparatus; (10) for catalytically processing a gas stream (13) passing therethrough to reduce the presence of NO therein, wherein the apparatus includes a first catalyst (20) composed of a silver containing alumina that is adapted for catalytically processing the gas stream at a first temperature range, and a second catalyst (22) composed of a copper containing zeolite located downsteam from the first catalyst, wherein the second catalyst is adapted for catalytically processing the gas stream at a lower second temperature range relative to the first temperature range.
(FR)L'invention concerne un procédé et un appareil (10) pour traiter catalytiquement un flux gazeux (13) traversant ledit appareil, afin de réduire sa teneur en NO, ledit appareil incluant un premier catalyseur (20) composé d'alumine contenant de l'argent adaptée pour le traitement catalytique d'un flux gazeux dans une première gamme de températures, et un second catalyseur (22), composé d'une zéolithe contenant du cuivre, situé en aval du premier catalyseur, le second catalyseur étant adapté pour le traitement catalytique d'un flux gazeux dans une seconde gamme de températures inférieure à la première gamme de températures.
