中文摘要：
以硫酸亚铁和氯化亚锡为原料,经草酸盐共沉淀法制备了一系列Sn O2-Fe2O3催化剂（Cat-1-Cat-3）,其结构和性能经FT-IR,XRD,SEM,TEM和N2-BET表征。考察了模拟烟气条件下,Cat-1-Cat-3低温催化脱除NO和抗SO2中毒的性能。结果表明：Cat-2[r=n（Sn）∶n（Fe）=1∶2]结晶度较高,粒径3μm-6μm,热稳定性好,催化脱硝效率（α）较好[T=160℃,α=83.7%;T=180℃-360℃,α〉85%];Cat-2于240℃经SO2毒化40 min,α降低至66.2%。
英文摘要：
A series of low temperature denitration catalysts（ Cat-1 - Cat-3） were prepared by oxalate co-precipitation method,using Fe SO4 and Sn Cl2 as materials. The structures and performances were characterized by FT-IR,XRD,SEM,TEM and N2-BET. The catalytic activities of low temperature denitration and anti-SO2 performances of Cat-1 - Cat-3 were investigated by simulated flue gas experiments. The results showed that Cat-2[r = n（ Sn） ∶ n（ Fe） = 1 ∶ 2] indicated high crystallinity and well thermostability with particle size of 3 μm - 6 μm. Cat-2 also exhibited better catalytic denitration activity（ α） [T = 160 ℃,α = 83. 7%; T = 180 ℃ - 360 ℃,α 85%]. α of Cat-2 was declined to66. 2% after poisoned by SO2 for 40 min at 240 ℃.
