文摘
- •
NO removal and N2O inhibition are achieved in low-temperature SCR with MnOx/Ti catalyst.
- •
N2O mainly originated from direct oxidation of NH3 and reaction of NO and adsorbed NH3.
- •
Reaction of NO and adsorbed NH3 plays a dominate role in N2O formation at temperature below 240 °C.
- •
Doped V promotes Lewis acid sites which effectively restricts N2O formation.
- •
Mn(0.4)Ce(0.1)V(0.01)/Ti ensures high NO conversion efficiency and low N2O formation.
