【Abstract】 The flue gas temperature of alumina calciner is 140～180℃. In this paper, a new manganese-based low-temperature SCR catalyst is prepared with low-cost manganese salt as raw material. Under the optimal synthesis conditions, the SCR rate of manganese-based catalyst is more than 75% at 100 ℃ of simulated flue gas, and the SCR rate remains above 90% within the range of 150～300 ℃.更多还原
