Abstract： Hydrogen purification technology is an essential part of the efficient use of hydrogen energy by removing impurities from hydrogen-containing raw gases, and various methods have been developed to obtain high purity H₂ for different industrial needs. Based on the purification principle, H₂ purification methods can be divided into physical methods such as pressure swing adsorption, membrane separation, cryogenic distillation methods, and chemical methods such as CO preferential oxidation, CO selective methanation and metal hydride separation methods. The technical principles and research progress of the different purification methods are reviewed in this paper. The choice of H₂ purification process should be based on the composition of the raw gases, the requirements of the product gas and the specific scale of purification. The combination of different processes, the development of advanced materials as well as novel process intensification technologies are needed for future research.

Keywords： hydrogen purification pressure swing adsorption CO preferential oxidation CO selective methanation
