Description
  • Two types of catalytic washcoats with different properties can be present simultaneously in a monolith channel, e.g. the flat foils and the corrugated ones in metallic monolith can be individually coated with specific type of the washcoat. The model of such multiphase, differentiated NOX storage and reduction (NSR) catalytic monolith converter has been developed. The results of the computations agree well with the experimental data. The dependences of integral NOX conversion on the lengths of the lean and rich phases and on the temperature of the inlet gas are discussed. The efficiencies of the low-temperature, the high-temperature and the differentiated NSR converters are compared at different operating conditions.

  • Dva různé druhy aktivní katalytické vrstvy mohou být umístěny současně v jednom kanálku monolitu, například různé typy katalytické vrstvy mohou být naneseny na rovné a zvlněné plechy v kovovém monolitu. Byl vyvinut model takového vícefázového, diferencovaného katalytického monolitu s ukládáním a redukcí NOX. Výsledky modelových výpočtů souhlasí s naměřenými daty. Je diskutována závislost celkové konverse NOX na délce fáze chudé a bohaté směsi (přístřik redukčních činidel). Je porovnána účinnost nízkoteplotního, vysokoteplotního a diferencovaného konvertoru za různých provozních podmínek. (cs)
