摘要
对当前我国煤层气抽采利用的现状及存在的问题进行了概述;根据抽采瓦斯浓度的不同,重点介绍了煤层气发电、蓄热氧化、物理萃取富集等各级低浓度煤层气主流利用技术的发展情况,并指出其中亟待解决的关键技术工艺难题及解决思路;分析强调了低浓度煤层气利用技术发展的重要性,并对其产业前景作出展望。
The present situation and existing problems of the extraction and utilization of coalbed methane（CBM） in China were summarized in this paper; according to the different concentration of gas extraction,the development of mainstream utilization technology of low concentration CBM at all levels was introduced,including CBM power generation,regenerative oxidation and physical extraction enrichment. This paper also pointed out the key technical problems and solutions that need to be solved urgently; it analyzed and emphasized the importance of the development of low concentration CBM utilization technology,look ahead to its industrial prospects.
