摘　　要：基于液氢容器高效氢吸附剂对使用方式、材料改性、性能评价和用量计算的需求,讨论真空夹层中的气体负荷来源和真空寿命,总结液氢容器常用氢吸附剂的种类、材料以及吸附性能研究方法.真空夹层主要的残余气体是材料放出的氢气,通过合理使用吸附剂可以显著延长容器寿命.根据吸气机理可将氢吸附剂分为低温吸附剂、金属氧化物、离子交换沸石分子筛和非蒸散型吸气剂4类,并从实验测试和理论模型2个方面总结了吸附性能的研究方法.The sources of gas load and vacuum life of the vacuum jacket were discussed based on the requirements of usage mode,material modification,performance evaluation and amount calculation for efficient hydrogen adsorbent in liquid hydrogen vessels.The types and ingredients of common hydrogen adsorbents and research methods of adsorption commonly used in liquid hydrogen containers were summarized.The hydrogen released by the materials was the main residual gas in the vacuum jacket and the vessel life can be significantly extended by the rational use of adsorbents.The hydrogen adsorbents can be classified into four categories according to adsorption mechanism:low temperature adsorbents,metal oxides,ion exchanged zeolite molecular sieves and non-evaporable getters.The research methods of adsorption performance were summarized in aspects of both experimental test and theoretical model.
