화학적 처리된 활성탄을 거친 NO-NO2의 저온 흡착 및 반응 특성에 대한 총설 |
| 초록 |
The technologies of NOx removal have been developed through efforts of many researchers. However, since NOx is very difficult to control, a perfect process has not yet been discovered. The most widely known commercial process is selective catalytic reduction (SCR) process. SCR process has high removal efficiency of NOx. However, with the introduction of issues such as catalyst poison, deactivation of catalyst due to presence of oxygen, non-reacted reductant emissions and economic inefficiency, researches on ways to resolve such issues are actively under progress. The possibility of removing harmful gas using carbon materials during adsorption process has been examined due to the unique characteristic of carbon materials themselves. As a result, it was induced that if alkali metal hydroxide is impregnated in carbon material, the effect of controlling NOx is maximized. In particular, potassium hydroxide (KOH) used as impregnant in this study has positioned itself as one of the promising chemical substances to increase removal efficiency of NOx by enhancing selective adsorptivity of NOx. Here, the reason for the increase in removal efficiency of NOx caused by the changes in the surface functional group due to impregnation of KOH and effect of catalytic action. Therefore, the information on modification of surface chemistry due to adsorption of NOx can be regarded extremely significant in understanding the adsorption reaction. However, obvious examination of the selective adsorption behavior and surface chemistry caused by NOx adsorption on the surface of activated carbon has not yet been made. |
