Poster summary

Nitrous oxide is a strong greenhouse gas. Nitrous oxide is a contributor to the destruction of ozone in the stratosphere and a strong greenhouse gas. A reduction of N2O emission from industrial sources is indispensable. To date, there are two EnviNOx® technologies for the combined removal of N2O and NOX from tail gases a zeolite catalyst, both technologies require additional energy consumption for tail gas heating up to 300–600°C. A single-reactor scheme for the abatement of NOX and N2O under the conditions of a SCR reactor in Russia at 220-280C can be economically advantageous. For such a scheme, it is preferable to use a low-temperature N2O decomposition catalyst with the geometry of a honeycomb block or cylindrical granules. The second layer of the N2O decomposition catalyst must have mechanical strength, uniformity and must not create hydraulic resistance.
