英文摘要 | The selective catalytic reduction (SCR) of NO with propylene was investigated over Cu/Al2O3 catalyst by using fixed-bed reactor and in situ FTIR and compared with Ag/Al2O3 which has a relative high activity in C3H6-SCR of NO. The highest conversion of NO is only 40% at about 650 K, when the catalyst was exposed to a gas mixture of NO/C3H6/O-2/N-2 = 0- 08%/0. 171 4% /10% /balance with W/F= 0. 018 g (.) s/mL. Surface R-NO2 and R-ONO species, which were observed on Ag/Al2O3 catalyst as the precursor of -NCO species, can hardly be found on Cu/Al2O3 catalyst surface in FTIR spectra under the same condition. This results in the low activity of Cu/Al2O3 catalyst for NO reduction. Through dynamic FTIR experiment, it was found that NOT species, which are dominant surface species over Cu/Al2O3 catalyst, have a low activity with C3H6, so that the reaction producing R-NO2 and,R-ONO is very difficult to take place. |
