NON-THERMAL PLASMA and CATALYST SYSTEM FOR SIMULTANEOUSLY OXIDIZING SO2 AND NOz
In the present study, a new non-thermal plasma system assisted with catalyst was developed to simultaneously oxidize NOx and SO2. Moreover, the effect of parameters such as temperature, atmosphere, residence time, and additives (NH3 and methanol) on NOx and SO2 conversion rate was also evaluated. The results revealed that the new system could greatly promote the NOx conversion rate while the new system only had a slight influence on the SO2 oxidization rate. High temperature suppressed the NO oxidization, and promoted the SO2 oxidation. The long residence time was beneficial to the NOx and SO2 oxidization. In the absence of water, the additive of NH3 can improve NO, NOx, and SO2 oxidization rate due to the reactions between NH3 and NOx, or SO2. Contrary to NH3, methonal had a negative effect on NOx and SO2 oxidization.
