Abstract

L'invention se rapporte à un filtre catalytique pour la dépollution d'un gaz chargé en particules de suies et de polluants en phase gazeuse, obtenu par imprégnation dans une solution catalytique d'une structure de filtration constituée par un ensemble d'éléments monolithiques du type nid d'abeille, dans laquelle la porosité du ciment utilisé comme revêtement et/ou comme joint et/ou comme bouchon est inférieure à la porosité du matériau constituant le ou lesdits éléments.
