| Outline of Final Research Achievements |
Simulated flue gas was fed into a photochemical reactor with an excimer lamp generated 172 nm wavelength, which located at the center of the reactor. The de-NOx behavior was examined without any catalyst and no reducing agent at the room temperature. The de-NOx ratio was changed greatly with initial NO concentrations and gas residence time (SV). Although the partial pressure of water and the oxygen concentration slightly influence the de-NOx ratio, the effects of CO2, CO, SO2, and gas temperatures on de-NOx ratio were not affected.
The mechanism of de-NOx by photochemical reaction was examined by elementary reaction simulation. It was found that NO in the flue gas was reduced to molecular nitrogen at the long gas residence time. Co-products in the de-NOx reaction were HNO3 and NO2.
