| 摘 要： | 以铁矿石为催化剂对烟气进行选择性催化还原法(SCR)脱硝，研究不同铁矿石对烟气中低浓度氮氧化物NOx的催化还原特性，对铁矿石进行XRD和Mssbauer分析，确定对NOx脱除起关键作用的物质。研究结果表明：对NOx脱除起催化作用的主要成分是α-Fe 2O3；经不同温度煅烧后的A铁矿石在较低的温度180～230 ℃对NOx有较高的催化性能，在200 ℃左右脱硝效率达到85%以上。

| 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-Fe 2O3 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%. |
