ハニカムフィルタ及びハニカムフィルタの製造方法
Abstract:
(EN)
This honeycomb filter comprises: a ceramic honeycomb base material having a plurality of cells for causing fluid to flow therethrough aligned in the longitudinal direction and having cell walls therebetween, said base material having one end section sealed on either the fluid inflow side or the fluid outflow side of the cells; a filter layer formed on, among the surfaces of the cell walls, the surface of cell walls of cells having the end section on the fluid inflow side open and the end section on the fluid outflow side sealed; and, in the cell walls having the filter layer formed thereon, an SCR catalyst supported by the surface of the cell walls of cells having the end section on the fluid inflow side sealed and the end section on the fluid outflow side open. The honeycomb filter is characterized by including a section fulfilling a < b, when the average pore diameter of pores in the filter layer is a (µm) and the average particle diameter of particles configuring the SCR catalyst is b (µm).
(FR)
La présente invention concerne un filtre en nid d'abeilles comprenant : un matériau céramique de base en nid d'abeilles comportant une pluralité de cellules, à travers lesquelles un fluide peut s'écouler, alignées dans la direction longitudinale et séparées par des parois, ledit matériau de base ayant une section terminale scellée du côté de l'entrée du fluide ou du côté de sortie du fluide des cellules ; une couche filtrante formée, parmi les surfaces des parois des cellules, sur la surface des parois des cellules ayant la section terminale ouverte du côté de l'entrée du fluide et la section terminale scellée du côté de sortie du fluide ; et, dans les parois des cellules sur lesquelles la couche filtrante est formée, un catalyseur de réduction catalytique sélective supporté par la surface des parois des cellules ayant la section terminale scellée du côté de l'entrée du fluide et la section terminale ouverte du côté de sortie du fluide. Le filtre en nid d'abeilles est caractérisé en ce qu'il comprend une section pour laquelle a < b, où a (µm) est le diamètre moyen des pores dans la couche filtrante et b (µm) est le diamètre moyen des particules du catalyseur de réduction catalytique sélective.
