A Study of Nitrous Oxide Decomposition over Calcium Oxide in Combustion Condition
Shun D, Bae DH, Paek JY, Park YS
A study of N2O decomposition reaction over a bed of CaO particles in a fixed bed reactor has been conducted. Effects of parameters such as concentration of inlet N2O, reaction temperature and effects of CO, CO2, O2, and NO gas presented in the combustion gas environment have been investigated. The experiment showed that the N2O decomposition reaction was accelerated by the increase of reaction temperature, and the existence of CO, while the reaction was hindered by the existence of CO2, NO. O2 also affected the N2O decomposition. Heterogeneous gas-solid reaction kinetics were proposed for the reaction conditions and compared with homogeneous reaction kinetics.
