摘　　要：综述了常用氢气纯化的方法及研究应用现状,对氢气纯化的各种方法进行了分析与评述。通过比较,变压吸附法因其对原料气的纯度要求较低、脱氢深度较高等优点,成为粗氢纯化时的最佳选择;钯金属催化及金属氢化物法都可以用来对纯度99%及以上的氢气进行纯化,得到纯度更高的氢气。介绍了各种氢气纯化方法的工业及研究应用,对研制更廉价、更高效氢气纯化装置提出了建议。Common methods of hydrogen purification,status of their research and application were summarized. By analyzing and comparing different methods, it was pointed out that the pressure swing adsorption method was applicable for hydrogen purification when coursing hydrogen, because of the raw gas purity requirements were lower and higher dehydro- genation depth,etc. Palladium catalysis and metal hydride method can be used when raw gas had the purity of 99% or more. Suggestion for the development of design and made for hydrogen purification devices which were cheaper and more efficient for hydrogen purification were given.
