A recuperative heat exchanger is used for thermal decomposition of nitrous oxide in gas mixtures, by first heating the gases to 800-1200 degrees C, and then cooling. The recuperator may be filled with inert particulates or packings e.g. honeycomb structures or rings. The packing may be alumina ceramic, silicon carbide, silicon dioxide , etc. Typically at temperatures of approximately 800 degrees C, and in the presence of NOx, a residence time of about 2 seconds is required for complete decomposition of approximately 11% v/v N2O. |
