THE REACTION CHARACTERISTICS OF NO AND SO2 IN THE DIELECTRIC BARRIER DISCHARGE PLASMA PROCESS

ABSTRACT
Many factors affect the reaction characteristics of nitrogen oxides and SO2 in a dielectric barrier discharge reactor. Changing the SO2 initial concentration, oxygen content and water vapor content to study the reaction mechanism of NO and SO2 in the dielectric barrier discharge plasma process has been conducted. It was shown that the initial concentration of SO2 varied in a larger scope has little effect on the reaction characteristics of NO and SO2 in the N2/SO2/NO system. Increasing the water vapor content in the N2/NO/SO2/HO system would reduce the concentration of SO2 significantly in the flue gas, and the influence on SO2 is more obvious than on NO. Then, the influence of oxygen on the reaction characteristics of SO2 is not obvious, increasing the O2 concentration in the N2/NO/SO2/O2 system, the changed of SO2 concentration is less than 10%. But the adding of O2 affects the reaction of NO in the dielectric barrier discharge process obviously, it can promote the conversion of NO2 and other NOx, at the same time, the generation of NO was also being accelerated under certain conditions. By analyzing the reaction mechanism, it was found that the activated radicals produced in the dielectric barrier discharge process concerned SO2 reaction mainly OH, while related the reaction of NO, the O and N play an important role. Through the experiment and analysis, it was also deduced that there are oxidation and reduction reactions existed at the same time, also the generation and removal of NO occurred simultaneously.
