Definitions
- Composite catalysts of various compositions according to the present invention were tested in a quartz reactor, through which passed a mixture of nitrous oxide and helium or tail gases from a pilot nitric acid installation.
- the composition of the tail gases was identical to that occurring in industrial nitric acid installation.
- the research on the 5 % of nitrous oxide in helium mixture was performed in a flow-through quartz reactor with sinter, in the range of temperatures from ambient to 450 °C, at a GHSV load of 7000 h " .
- the composition of the post-reaction mixture was determined using a mass spectrometer, measuring the partial pressures of nitrous oxide as well as its decomposition products: oxygen and nitrogen.
- the precipitate was maintained in the parent solution for 15 h at ambient temperature, after which the precipitate was drained off and rinsed, until reaching a pH of filtrate equal 7.0-7.5.
- the resulting precipitate was dried at a temperature of 120 °C for 15 hours, and then the filtrate was impregnated with a 0.06 molar solution of potassium carbonate, dried at a temperature of 120 °C and calcined at a temperature of 400-450 °C for4 hours, gradually increasing the temperature from 120 to 400 °C.

Abstract
L'invention concerne un catalyseur composite qui contient 25 - 88,6% en poids en oxyde de cobalt, 10,99 - 60% en poids en oxyde de zinc comme composants importants ; l'oxyde de zinc est introduit en deux étapes, lors de la précipitation et avant la formation du catalyseur. Le rapport de l'oxyde de zinc introduit lors de la précipitation et de l'oxyde de zinc ajouté avant la formation du catalyseur est de 1 :00,26-13,3 , il contient également des composants qui améliorent l'activité, sous la forme de métaux alcalins à 0,01 - 5% en poids en termes d'oxydes de ces métaux, et du graphite à 0,4 - 10%. De préférence, les métaux alcalins présents dans la composition du catalyseur sont le sodium et/ou le potassium.
