| description | A catalyst for low-temperature decomposition of dmitrogen oxide in tail gases from a nitric acid plant based on cobalt oxide comprises, calculated as simple oxides: cobalt oxide at the level of 45.00-99.97 weight %, nickel oxide at the level of 0.01-30.00 weight %, zinc oxide at the level of 0.01-20.00 weight % as principal structural components and activity promoters in the form of alkali metals, such as Na and/or K, at the level of 0.01-5.00 weight % and shape-facilitating alkaline earth metal oxides, such as Ca and/or Mg, at the level of 0.01-5.00 weight %. The invention provides also a process for the preparation of a catalyst.
La présente invention concerne un catalyseur pour la décomposition à basse température d'oxyde de diazote dans des gaz résiduaires provenant d'une installation de production d'acide nitrique à base d'oxyde de cobalt comportant, en termes d'oxydes simples : 45,00 à 99,97% en poids d'oxyde de cobalt, 0,01 à 30% en poids d'oxyde de nickel, 0,01 à 20% en poids d'oxyde de zinc comme principaux constituants structurels et des promoteurs d'activité sous forme de métaux alcalins, tels que Na et/ou K compris entre 0,01 et 5% en poids et des oxydes métalliques alcalino-terreux comme agents facilitant la conformation, tels Ca et/ou Mg compris entre 0,01 et 5% en poids. L'invention concerne également un procédé pour la préparation d'un catalyseur. |
