Definitions
- honeycomb bodies e.g. made of titanium dioxide with a coating of vanadium or tungsten oxides.
- oxides of cobalt and nickel is also known.
- the water gas reaction which preferably takes place under certain conditions also leads to complete cleavage of aliphatic and aromatic hydrocarbon structures.
- the gasification of coke and gum deposits on the catalytic converter is promoted, thereby achieving high long-term activity of the catalytic converter.
- the honeycomb molded body can be arranged as a battery of several molded bodies both horizontally and vertically and in inclined directions according to the combustion chamber in accordance with the respective spatial conditions. It is expedient if a plurality of shaped bodies are arranged in a form-fitting manner horizontally and / or vertically and / or inclined to Arrange the flue gas direction one above the other, side by side and / or one behind the other in a size or number sufficient for catalytic cleaning.
- the actual configuration can easily be determined for the person skilled in this field depending on the amount and type of the harmful components to be removed from the fuel / flue gas and the selection of the corresponding catalyst (doping).

Abstract
La présente invention concerne un procédé d'oxydation catalytique de produits nocifs organiques qui se trouvent dans les fumées d'origines et de compositions diverses. L'inconvénient de la pyrolyse et de la combustion à haute température qui visent à éliminer les déchets solides, liquides et gazeux, réside dans le fait que les hydrocarbures ne sont pas entièrement dégradés et sont partiellement oxydés. Jusqu'à présent, on n'est parvenu à obtenir une oxydation totale que sur des catalyseurs à base de métaux précieux, pour les gaz d'échappement de véhicules. Le but de l'invention est donc la mise au point d'un procédé simple et applicable techniquement, qui permette de transformer les hydrocarbures contenus dans les fumées non épurées, à l'aide d'un catalyseur et avec une réaction qui soit intéressante du point de vue énergétique. Le nouveau procédé se caractérise en ce qu'un bloc en nid d'abeilles à structure en tamis, dont les alvéoles constituées par un aluminate de calcium, modifié ou non, servent de catalyseur, est placé dans un flux de fumées non épurées, immédiatement en aval de la chambre de combustion. Les fumées sont à une température de 400 à 1 300 °C et elles séjournent de 0,2 à 3 secondes dans le bloc en nid d'abeilles.
