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 .
