摘　　要：介绍了变压吸附(PSA)技术浓缩煤层气、油田气以及垃圾填埋气中甲烷(CH4)的国内外研究和应用状况,分析了吸附剂以及PSA工艺对CH4/N2分离效果的影响,着重讨论了活性炭与碳分子筛(CMS)吸附剂在分离CH4/N2混合物中的应用,指出了目前PSA用于浓缩CH4/N2中CH4研究中存在的不足,并展望了其发展趋势。The research progress in the concentration of methane from coal-bed gas, oil-field gas and dumping ground gas by the pressure swing adsorption （PSA） and its application are introduced. The influences of the adsorbents and the PSA technology on the separation effect of CH4/N2 mixtures are analyzed. The application of active carbon and carbon molecular sieve（CMS） in the separation of CH4/N2 is discussed.The problems in PSA technulogy for the separation of CH4 from CH4/N2 are pointed out, and the developing trend in this field is also reviewed.
