Ru-HZSM-5 촉매를 사용한 산화질소 SCR에서 TSR의 효과 및 탄소상 침적물의 역할 |
| 초록 |
The SCR of NO with propene in the presence of O2 over Ru-HZSM-5 catalyst was investigated using temperature swing reaction (TSR) technique. In the period of elevating temperature to 598K, the conversion of NO to N2 was transiently increased up to 75% with duration of one minute. It was recognized that a sudden activation of carbonaceous deposits accumulated on the catalyst played an important role in the remarkable enhancement of the catalytic activity. With the adding of water vapor, the duration of the enhancement was significantly prolonged. We suggest that the TSR technique using Ru-HZSM-5 catalyst is an advantageous method in the SCR of NO, considering the activity enhancement and the simplicity in operation.
