Abstract:
A process for the thermal decomposition of N.sub.2 O in N.sub.2 O-containing gases at from 800 to 1200.degree. C., which comprises passing the N.sub.2 O-containing gas through one or more recuperative heat exchangers or regenerative heat exchangers having a high-temperaturc zone and low-temperature zone in such a way that the gas to be reacted is passed through a charge of heat transfer material so as to heat it to a temperature in the range from 800 to 1200.degree. C. and the N.sub.2 O present is decomposed thermally, and cooling the reacted gas by heat exchange so as to heat the heat charge of heat transfer material and the gas to be reacted, and wherein the excess heat of reaction is removed as hot steam by means of a stcam generator installed in the high-temprature region of the charge of heat exchange material being at a temperature in the range from 800 to 1200.degree. C.
