| abstract |
The invention relates to an apparatus and to a process for decomposing dinitrogen monoxide. The apparatus comprises a gas inlet 1 for supplying a nitrogen monoxide-containing gas, a first heat exchange medium 3 for exchanging heat between an offgas and the nitrogen monoxide-containing gas, a heating apparatus 4 for occasional heating of the nitrogen monoxide-containing gas, a fixed bed reactor 5 in which a catalyst is accommodated, in order to decompose the dinitrogen monoxide in the dinitrogen monoxide-containing gas, a gas outlet through which the offgas leaving the fixed bed reactor can be conducted out via the heat exchange medium 3. According to the invention, the catalyst is suitable for decomposing dinitrogen monoxide at temperatures below 800°C, especially preferably below 450°C, more preferably below 400°C. The fixed bed reactor 5 is configured for operation in an adiabatic state. |
