A study of nitrous oxide decomposition over calcium oxide

A study of N2O decomposition reaction in a fixed bed a reactor over bed of CaO particles has been conducted. Effects of parameters such as concentrati on of inlet N2O gas, reacting temperature and content of CO2/CO gas present in the reacting materials on the decomposition reaction have been investig ated. The results showed that the conversion of N2O decomposition was accel erated by the increase of reaction temperature, and the existence of CO, wh ile the rate was hindered by the existence of CO2. Heterogeneous gas solid reaction kinetics was proposed for N2O decomposition and compared with homo geneous reaction kinetics.
