| description | The invention relates to the automotive industry, in particular to designing devices for detoxifying exhaust gases of an internal combustion engine and more specifically to honeycomb electrically heated structures. The inventive catalytic unit consists of two metal strips, each of which is provided with a coating made of chemically active substances applied by thermal spraying, wherein one strip is coated with a substance in the form of nitrogen oxide adsorbents and the other strip is coated with a catalyst for oxidising a carbon oxide and hydrocarbons. One strip is corrugated. Afterwards, the two strips are folded in such a way that transversal channels are formed, wherein said channels have a three-angle cross-section, two sides thereof are coated with the adsorbent and the third side is coated with an oxidising catalyst or vice versa. When the exhaust gases pass through, the nitrogen oxides are sorbed on certain walls of the channels and a carbon oxide and hydrocarbons are oxidised in such a way that a carbon dioxide and water vapours are sorbed on the other walls. When the absorbent is saturated with nitrogen oxides, the catalytic unit is heated by electric current and a reducing gas in added therein, thereby generating the desorption and reduction of nitrogen oxides.
L'invention appartient au domaine de l'industrie automobile et concerne notamment la conception de dispositifs destinés à neutraliser les gaz d'échappement des moteurs à combustion interne. Elle se rapporte au domaine des structures en alvéoles réchauffées par le courant électrique. Selon l'invention, un bloc catalytique est réalisé à partir de deux bandes métalliques; sur chacune d'elles, on applique par pulvérisation thermique un revêtement de substances chimiquement actives. Sur une bande on applique une substance absorbant les oxydes d'azote, et sur l'autre bande on applique un catalyseur d'oxydation des oxydes de carbone et des hydrocarbures. Une des bandes est soumise au gaufrage. Les deux bandes sont ensuite enroulées de manière à former des canaux ayant une section transversale triangulaire; deux côtés de chaque canal sont recouverts d'un absorbant et le troisième est recouvert d'un catalyseur d'oxydation (ou vice versa). Pendant la circulation des gaz d'échappement les oxydes d'azote sont sorbés sur des parois du canal, et l'oxyde de carbone ainsi que les hydrocarbures sont oxydés jusqu'au dioxyde de carbone et des vapeurs d'eau sur les autres parois.
