Abstract
The reaction characteristics of CH3OH-NO-O2 (N2 base) system were investigated using the synthetic bombe gas, electric furnace, and quartz test tube (18mm in diameter). Operating factors were temperature, residence time, CH3OH/NO molar ratio and O2 concentration. Results were summerized as follows.
1) NO was oxidized to NO2 at about 550∼850°C in CH3OH-NO-O2 system, and CH3OH was decomposed rapidly by the effect of NO.
2) High oxidation ratio of NO to NO2 was obtained in the case of high concentration of O2, and high molar ratio of CH3OH/NO.
3) Using the Kinetic simulation model, the effect of operating factors were analysed.The important role of HO2 radical in NO oxidation to NO2, and H radical in NO2 reduction to NO were suggested.
