煤层气中甲烷富集的研究进展，介绍了变压吸附法（PSA）处理油田气和倾倒地面气的原理及应用情况，分析了吸附剂和变压吸附工艺对CH 4/N2混合气分离效果的影响，介绍了活性炭和碳分子筛（CMS）在CH 4/N2混合气分离中的应用指出了变压吸附法分离CH_4/N_2中的CH_4存在的问题，并展望了该领域的发展趋势。
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 technology for the separation of CH4 from CH4/N2 are pointed out,and the developing trend in this field is also reviewed.
