摘　　要：采用水热合成法制备了SAPO-5分子筛,并通过浸渍法制备了一系列的Fe-SAPO-5吸附剂,并通过XRD和IR手段对其进行表征。以Fe-SAPO-5作为吸附剂进行二氧化碳气体的提纯精制研究,并研究了不同负载量、温度及空速对其性能的影响。实验结果表明,在反应温度为25℃,压力1.0 MPa,空速为80 m L/min的条件下,9%(wt)Fe Ox/SAPO-5吸附效果最佳,产品纯度可达99.99%。SAPO-5 molecular was synthesized by hydrothermal method, andthenthe Fe-SAPO-5 sorbent was prepared by impregnation method. The sample was characterized by means of XRD and IR techniques. The Fe-SAPO-5 sorbent was usedtopurifycarbondioxide.Effectofdifferent load, temperature and space velocityon properties of prepared sorbent was investigated.The results show thatwhenthe experimentaltemperature is25℃,the pressure is1 MPa andspace velocityis80 mL/minand FeOXcontentis 9 %（wt）, thepurityof CO2can reach to 99.99%.
