Abstract

L'invention concerne la fabrication et les applications de dispositifs catalytiques pour le traitement de fluides. Le dispositif comprend un récipient ayant des passages d'entrée et de sortie de gaz et dans lequel sont assembés plusieurs constituants dont chacun (petit en comparaison du récipient) comprend un substrat (fil ayant une configuration tridimensionnelle ouverte) portant en surface un revêtement solide d'une matière catalytique. On fait passer dans le dispositif le fluide à traiter. Application : traitement des gaz d'échappement d'un moteur d'automobile.
