Denitration of the gas-fired boiler flue gas based on

Apr 01, 2019 · The denitration performances of transition metal oxide oxygen carriers (OCs) including CuO/Al 2 O 3, MnO 2 /Al 2 O 3 and NiO/Al 2 O 3 for the gas-fired boiler flue gas were investigated. The results showed that NO was able to be reduced to N 2 through a direct reaction with the reduced OCs, and at the same time, the reduced OCs were converted to the oxidized OCs. . Then, the oxidized OCs …
