摘　　要：随着全球能源转型,氢气作为清洁能源受到广泛关注,然而其高纯度要求和生产过程中的杂质问题催生了对高效分离技术的需求。主要的氢气分离方法包括变压吸附法(Pressure Swing Adsorption,PSA)、膜分离和深冷分离。PSA法已广泛应用,具有高回收率和成熟技术;膜分离利用氢气与其他气体在膜材料中的渗透差异,具有较高分离速率和低成本优势;深冷分离通过低温冷却气体,适用于大规模生产并能提高氢气纯度。尽管面临能耗和成本挑战,随着技术进步,氢气分离技术在能源转型中的作用将更加重要。With the global energy transition,hydrogen has received widespread attention as a clean energy source,however,its high puri-ty requirements and impurity problems during production have created a demand for efficient separation technologies.The main hydrogen separa-tion methods include PSA,membrane separation,and cryogenic separation.PSA has been widely used,with high recovery rates and proven technol-ogy;membrane separation utilizes the difference in permeation between hydrogen and other gases in the membrane material,with high separation rates and low costs;and cryogenic separation cools the gas at low temperatures,which is suitable for large-scale production and improves the purity of hydrogen.Despite the energy and cost challenges,the role of hydrogen separation technology in the energy transition will become more important as technology advances.
