| Abstract: | The transient kinetics of the selective catalytic reduction(SCR)of NO with NH3 and the influence factors of V2O5-WO3/TiO2 catalyst activity at low temperature were studied in a fixed-bed reactor by temperature programmed technique and transient response technique.The experimental results showed that the promoting effect of oxygen on NO conversion was abtained,that SCR activity decreased when H2O was added,and that NO conversion was en-hanced with the presence of SO2.At low temperature,SCR reaction is in lin... |
