Enhancement of NOx removal efficiency under low operation temperature condition by plasma-catalyst |
| 초록 |
At low operating temperatures (≤ 300 ℃), the NOx removal efficiency in exhaust gases is generally low, due to plasma-catalyst is mainly oxidize NO to NO2. In this work, a dielectric barrier discharge (DBD) reactor coupled with the ZSM-5-supported bimetallic catalysts (Co-ZSM-5 and Ag-ZSM-5) was investigated to improve NOx reduction efficiency under low operation temperature condition. Aiming at finding out suitable catalyst materials and understanding the interaction between plasma and catalyst in NOx reduction process. The effect of the reaction temperature and the energy density on the NOx reduction was examined and discussed. The result showed that the presence of the elements (Co and Ag) in the catalysts significantly improved the adsorption of NO2 at low temperatures, so that the performance of catalytic NOx reduction could be kept high over a wide temperature range. |
