摘要:

甲烷(CH4)是全球第二大温室气体,占全球温室气体排放量的19%,其20年时间尺度内增温潜能是二氧化碳(CO2)的80倍以上,成为重点关注的温室气体减排方向。对于体积分数在6.0%以下的超低浓度甲烷,尽管排放源分散和浓度变化范围广等特点使得减排技术面临诸多挑战,但对其进行减排处理具有重要的环保意义。本文针对超低浓度甲烷减排及资源化利用的研究进展进行了讨论、分析和总结。首先,概述了人类活动排放甲烷的主要来源,着重分析了超低浓度甲烷主要的排放源;其次,阐述了超低浓度甲烷减排的政策及市场机制;最后,着重讨论了超低浓度甲烷资源化利用目前主要采用的技术,包括分离提纯浓缩、热氧化利用和生物催化利用等技术的工作原理和开发研究进展。未来,需要进一步加强技术创新和完善政策机制,实现超低浓度甲烷的减排及资源化利用,助力“双碳”背景下能源的可持续发展。

Abstract:

Methane (CH4) is the second largest greenhouse gas in the world, accounting for 19% of the global greenhouse gas(GHG) emissions. Its global warming potential is more than 80 times that of carbon dioxide (CO2) on a 20-years timescale and has become a key concern for GHG emission reduction. For the ultra-low concentration methane below 6.0%, its emission and utilization still have important environmental significance, although the characteristics of dispersed emission sources and wide range of concentration variations make abatement technology face many challenges. In this paper, the research progress on emission abatement and resource utilization of ultra-low concentration methane was analyzed and summarized. Firstly, the main emission sources of methane in human-being activities were overviewed, specially focusing on the emissions of ultra-low concentrations of methane. Secondly, the policy and market mechanism of ultra-low concentration methane emission reduction were described. Finally, the technologies currently used for resource utilization of ultra-low concentration methane were especially discussed, including the working principles and development progress of separation-purification-concentration, thermal oxidation utilization and biocatalytic utilization. In the future, it is necessary to further strengthen technological innovation and improve policy mechanisms to achieve emission reduction and resource utilization of ultra-low concentration methane and promote the sustainable development of energy in the context of carbon peaking and carbon neutrality.

Key words: ultra-low concentration methane, emission, resource utilization, separation-purification-concentration technology, thermal oxidation utilization technology, biocatalytic utilization
