Abstract
Recuperative heat exchangers or regenerative heat exchangers are used for the thermal decomposition of N,O in N,O-containing gases. The process for the thermal decomposition of N,O in N,O-containing gases at from 800 to 1200° C. comprises passing the N,O-containing gas through one or more recuperative heat exchangers or regenerative heat exchangers in such a way that when the gas to be reacted is passed through a charge of heat transfer material it is heated to a temperature in the range from 800 to 1200° C. and the N,O present is decomposed thermally, and cooling the reacted gas by heat exchange so as to heat the charge of heat transfer material and the gas to be reacted.
