摘要:
针对密闭空间低浓度二氧化硫气体危害人体健康的问题,本文采用将三乙醇胺负载于改性的5A分子筛制成吸附剂的方法,以去除低浓度有害SO2气体。通过固定床反应器检测硫化物的吸附容量,采用X-射线衍射仪(XRD)、扫描电子显微镜(SEM)、傅里叶红外光谱仪(FTIR)、X-射线光电子能谱仪(XPS)等表征吸附剂的性能。实验结果表明:SO2的吸附量主要受三乙醇胺的吸附量与反应温度的影响。TEA/MZs-100-20吸附剂对低浓度SO2气体显示出优异的吸附性能:在20℃下,三乙醇胺负载量为100wt%时,其穿透实验时间达到205 min,饱和吸附量达到91.41 mg/g。通过傅里叶红外光谱及XPS分析,证实了去除低浓度SO2的吸附反应机理。
