在液氮温度下采用容积法研究了5A、ZSM-5及其改性沸石分子筛对氢同位素的吸附分离性能,探讨了过渡金属盐负载和球磨等改性方法对氢同位素气体吸附的影响。结果发现,改性后分子筛上气体的吸附量普遍降低,但某些改性有利于H2和D2的分离。
The adsorption characteristics of hydrogen isotopes on 5A,ZSM-5 and their modified molecular sieves were studied at liquid nitrogen temperature with volumetric method.The effects of modification methods such as transition metal salt loading and ball milling on the adsorption behavior were discussed.It is observed that the adsorption amounts on the modified molecular sieves are reduced,but some modifications contribute to the separation between H2 and D2.
