| 英文摘要 | The selective catalytic reduction (SCR) of NO with C3H6 over Ag/Al2O3 in excess oxygen was studied. The Ag particles could evenly be dispersed on the surface of Al2O3 with an optimal Ag loading of 4%similar to6% and an average size of 15 nm. The NO conversion over 4%Ag/Al2O3 catalyst was above 90% under the conditions of GHSV = 50 000 h(-1) and theta = 430 similar to 550 degreesC. Organic nitro-compounds (R-ONO, R-NO2) and nitrogen dioxide formed during the SCR reaction resulted in the difference between NO and NO, conversion. The optimal NO reduction reactivity over Ag/Al2O3 was achieved in the presence of 7% O-2. The NO conversion decreased with the introduction of water, compared with the condition in the absence of water, because the formation of R-ONO and R-NO2 and subsequently their decomposition into Ag-NCO and Al-NCO on the surface of Ag/Al2O3 were suppressed. |
