- 摘要：MgAlFe水滑石在600℃以上焙烧后脱去表面水和层间水形成MgAlFe复合氧化物通过对MgAlFe复合氧化物BET、XRD表征和测定它的吸附硫容,发现它对SO2有优良的氧化吸附性能吸附SO2后MgO和尖晶石相消失,形成硫酸盐晶相用氢气对饱和吸附SO2后的MgAlFe复合氧化物进行还原再生,发现它经过10次吸附还原循环后,MgO和尖晶石的晶相依然存在,是一种可循环利用脱除SO2的环境催化材料.
- Abstract：When MgAlFe hydrotalcites calcined above 600℃ the surface and interlayer water lost and MgAlFe complex oxides formed The excellent properties of the adsorbing SO2 were found by the characterization of BET and XRD and measurement of the sulfur adsorptive capacity After the sulfur dioxide adsorption the crystals of the MgO and spinels disappeared and produced the sulfates Its reductive decomposition was studied by measuring reducibility in a quartz reactor with hydrogen.It was found that the crystals of the MgO and spinels were kept after the 10 cycles of oxidative adsorption and reductive decomposition,so MgAlFe complex oxides are a kind of the new important environmental catalytic material for sulfur dioxide removal
