摘　　要：系统回顾了磁致空气分离领域的主要研究进展,磁致空气分离是一种新兴的空气分离方法,它主要利用氧氮气体的磁化率差异实现分离.按照装置结构特点可以分为吸附富集法、轨迹偏转法、磁环法3种,通过不同方法的组合级联形成了形态多样的磁致分离系统.总结归纳了利用梯度磁场进行空气分离的技术要点及适用范围,磁致分离方法装置简单、预处理方便、能耗低,与传统分离方法相比,更适宜于低纯度氧气的生产.展望了磁致空气分离的发展趋势和应用前景,为了获得更高纯度的富氧空气,可以将磁致空气分离方法与传统低温精馏、膜分离方法有机结合,花费较少的代价来有效地提高传统方法的分离效率.Main research progress in magnetic air separation field was systematically reviewed . As an emerging air separation technology , magnetic air separation technology （MAST ） utilizes magnetic susceptibility difference to separate oxygen and nitrogen .MAST can be divided into three kinds according to its structure：absorption type ,side diffusion type ,and ring type .Various MAST systems were formed by the combination and cascading of these structures .Key techniques and major applications of MAST were summarized . MAST has advantages of simple structure , easy pretreatment , and low energy consumption , w hich is suitable to low concentration oxygen production . Development trends and application prospect were illustrated .Combination of MAST with traditional cryogenic distillation or membrane separation has the potential to produce high purity oxygen , w hich can improve separation efficiency with low extra energy and financial cost .
