Experiment on selective catalytic reduction of NO_x by NH_3 on iron ore catalysts
Abstract：Iron ore was used to the catalyst to remove NOx of flue gas in selective catalytic reduction（SCR）.In order to determine the main phases of reduction of nitrogen oxides,XRD and Mssbauer analysis were adopted.The results show that the major phases of iron ore is α-Fe2O3 which plays the important role in SCR.Under different temperature calcination,A iron ore has higher catalytic performance in the range of 180~230 ℃,especially in 200 ℃ its De-NOx efficiency reaches above 85%.
