Removal of NO by SCR system and combined plasma SCR system was investigated. The results indicate that overall NO conversion efficiency is improved by decreasing the ratio of NO/NO2 via application of glass beads.

 

On the other hand, MnOx-CeO2/TiO2 shows excellent performance for NO reduction at a temperature range of 100-200oC and NO removal efficiency can be significantly increased by the combination of plasma and SCR system. It is clear that NO removal efficiency depends on ratio of NO/NO2. Overall, plsama can enhance NO removal achieved with the SCR system.

Comment : NOx not only causes various adverse environmental effects such as acid rain, photochemical smog, deterioration of water quality and visibility, but also harms human lungs and respiratory system. Hence, how to effectively reduce NOx emissions at a reasonable cost has become an emerging issue. we attempt to develop a fast SCR system by combining non-thermal plasma technology (DBD). In this hybrid system, non-thermal plasma is applied as a pre-treatment process for converting part of the NO into NO2. As ratio of NO/NO2 is controlled at 1:1, it forms a fast SCR reaction for NOx removal.
