Nitrous oxide (N2O) has been extensively used in an oxidizing agent of semiconductor, LCD manufacturing processes, and inhalation anesthetics. Unfortunately, N2O has long atmospheric lifetimes and efficiently absorb infrared radiation, which contributes to greenhouse effect (GWP 310). Therefore, various means to reduce the emissions of N2O to minimize their environmental impact is currently explored in the related industries. In this study, we report on Thermal decomposition of nitrous oxide (N2O) in a tube type reactor using high frequency induction heating. Influence of parameters such as reaction temperature, contact time, concentration of N2O was determined. For the N2O decomposition, the reaction temperature and contact time had the strong effect on the decomposition rate. Thermal decomposition of N2O was observed at temperature above 700 ℃. Thermal decomposition of N2O was promoted by increasing the reaction temperature. Furthermore, the contact time played important roles for the complete decomposition of N2O. |
