摘要：
The invention relates to a method for producing nitric acid, according to which ammonia is burned on at least one catalyst net, especially a platinum net, in the presence of oxygen and the reaction gases are cooled. To prevent the release of laughing gas the invention is characterized in that before cooling the reaction gases are led downstream from the catalyst net across a catalyst having a stable temperature so as to transform the N2O contained in the reaction gases.
