CA 2559178

The present invention provides monolithic structural catalysts. The catalysts have a thin wall structure and are advantageous for catalyzing reactions of gaseous fluid or liquid fluid molecules, such as the denitration or selective catalytic reduction (SCR) of nitrogen oxides (NOx) in combustion flue gases. In an embodiment, the honeycomb-like monolithic structural body includes catalytically active outer peripheral walls and a plurality of catalytically active thin-walled inner partition walls, the thin-walled inner partition walls adapted to enhance fluid flow through the monolithic catalytic body and to increase interaction of the fluid molecules with the catalyst body.

Catalyseurs structuraux monolithiques qui possèdent une structure à parois minces et sont avantageusement utilisés pour catalyser des réactions de molécules de fluide gazeux ou liquide, telles que la dénitration ou la réduction catalytique sélective (SCR) d'oxydes d'azote (NO¿x?) dans des gaz de combustion. Dans un mode de réalisation, ledit corps structural monolithique de type à nids d'abeilles comporte des parois périphériques externes catalytiquement actives et une pluralité de parois de séparation internes minces catalytiquement actives, lesdites parois de séparation internes minces étant adaptées pour améliorer le flux de fluide à travers le corps catalytique monolithique et pour augmenter l'interaction des molécules de fluide avec le corps de catalyseur.
