Abstract (en)
[origin: WO2010072971A1] The invention relates to a honeycomb filtration structure, including an array of longitudinal parallel channels having parallel axes and separated by porous filtration walls, said structure being characterised in that the material used for the plugs provided at a first end of the filter has substantially the same composition and structural continuity as said walls, and in that the plugs provided at the second end of the filter have a chemical composition and/or structural composition different from that of the plugs provided at said first end.
