The invention pertains to a filter element (1) that can be easily adapted to the respective filtration task and in which the risk of the catalytically active components separating from the filter is largely eliminated. The filter element consists of a dimensionally stable porous formed body (3), the interior of which is partially filled with a catalyst material (8) or a material (8') that is coated with catalyst material such that a flow channel (10) remains open. It is possible to insert a perforated formed body insert (7, 7', 7'') that causes the flow channel to remain open. The intermediate space between the formed body (3) and the formed body insert (7, 7', 7'') is filled with a bulk catalyst material (8) or a bulk material (8') that is coated with catalyst material.
L'invention concerne un élément filtrant (1) pouvant être facilement adapté à une fonction de filtration respective et permettant d'éliminer le risque de décollement des composants à activité catalytique du filtre. L'élément filtrant décrit dans cette invention consiste en un corps formé (3) poreux et de dimension stable, dont l'intérieur est partiellement rempli d'un matériau catalytique (8) ou d'un matériau (8') enrobé d'un matériau catalytique, de manière à maintenir un canal d'écoulement (10) ouvert. On peut insérer une pièce rapportée formée perforée (7, 7', 7'') pour garantir le maintien du canal d'écoulement en position ouverte. L'espace intermédiaire entre le corps formé (3) et la pièce rapportée formée (7, 7', 7'') est rempli d'un matériau catalytique en vrac (8) ou d'un matériau en vrac (8') enrobé d'un matériau catalytique.
