| 摘 要： | 实现CH4-N2高效分离能够极大地推动常规天然气和非常规天然气这一类绿色低碳能源的利用，分子筛基吸附剂和膜材料具有优良的气体分离特性，而且对CH4-N2的分离颇具应用潜力。本文从对N2具有优先选择性吸附的N2/CH4分离（高浓度CH4纯化脱氮）和对CH4具有优先选择性吸附的CH4/N2分离（低浓度CH4富集脱氮）两方面综述了国内外分子筛吸附剂及分子筛膜的研究进展。详细地分析了分子筛骨架和平衡阳离子与其CH4-N2吸附分离性能之间的构效关系，并结合本文作者课题组的工作，提出了电中性（近中性）骨架分子筛对CH4-N2分离具有较好的分离效果。最后总结和展望了CH4-N2分离用分子筛吸附剂及分子筛膜的未来发展趋势。

| Abstract: | The high efficient separation of CH4-N2 can greatly promote the use of the conventional and unconventional natural gas which is a kind of green and low carbon energy. Zeolite-based adsorbents and membrane materials have excellent gas separation characteristics and great potential for CH4-N2 separation. In this review，the state of the art of zeolite adsorbents and membranes for CH4-N2 separation was discussed from two aspects：N2-selective separation（high-concentration methane purification） and CH4-selective separation（low-concentration methane enrichment）. The structure-activity relationship between the framework and cations of zeolite and its adsorption and separation performance of CH4-N2 was analyzed in detail. Combining with the previous work of our group, we proposed that the electroneutral (near-neutral) framework molecular sieve has better separation of CH4-N2. Finally, the future trend of molecular sieve adsorbents and membrane materials for CH4-N2 separation is summarized and prospected. |
