SCR of NO with natural gas over metal supported catalyst under lean conditions: activity and stability on water vapor |
| 초록 |
The selective catalytic reduction (SCR) of NO with methane over various metal-ion exchanged zeolites has received much attention. Methane is a main component of natural gas (90% in natural gas), which is widely utilized as fuel in various fields such as power plants, industrial furnaces etc. Therefore, a SCR system which can use methane as a reductant would be beneficial for not only natural gas fueled facilities, but also stationary NOx emission sources where natural gas supply is available. In SCR of NO, it is well known that a pronounced loss of activity is observed on the presence of water vapor over Pd/zeolite catalyst, indicating that Pd-agglomerization and zeolite-dealumination were promoted by water. So, in this study, ZSM-5 supported transition metal (Co or Ce), Pd combination catalysts were investigated in the SCR of NO with natural gas in the presence of water vapor under NO-lean conditions. |
