Abstract
The invention relates to a method of obtaining a homogeneous filtering structure for a catalytic application, which can be used as a particulate filter in an internal combustion engine exhaust line, said structure comprising a plurality of honeycomb filter elements in which a homogeneity criterion characteristic of the constituent support material of said elements, in the absence of a catalytic coating, is determined in a prior step, and then the elements making up the structure are selected by means of this homogeneity criterion so as to obtain a structure suitable for homogeneous deposition, within an element and from one element to another, of a catalyst for treating the pollutants in gas phase. The invention also relates to the homogeneous filtration structure obtained by said method.
