摘要
介绍了煤层气对大气的污染及温室效应，经计算，我国每年排放甲烷占全世界温室气 体排放量的５．９５％，利用煤的吸附性质可对煤层气进行抽放、净化和浓缩，同时指出ＰＳＡ技术在浓 缩净化煤层气方面存在的问题，建议为实现我国煤层气污染控制及资源化利用急需开展的研究工作。
-This paper describes pollution of coalbed methane to atmosphere and the greenhouse effect. Calculation Showed that the annually discharged volume of coalbed methane to the air in China amounted to 5.95 per cent of the total discharged volume of greenhouse gases in the world, and utilizing the adsorption feature of coal can realize the drainage, purification and concentration of coalbed methane. However, some problems still exist in the application of PSA technique for the concentration and purification of coalbed methane, therefore further study needs to be conducted so as to realize pollution control of coalbed methane and its resource utilization in China.
