Biogenic methane vs thermogenic methane
WebAug 31, 2024 · Synopsis: This paper has been prepared for the purpose of supporting the Committee’s scrutiny of the Climate Change Number 1 and Number 2 Bills.The paper provides an overview of methane and biogenic methane including information regarding overall emissions targets and specific methane targets as well as examples of Biogenic … WebBiogenic gas usually can be distinguished from thermogenic gas by chemical and isotopic analyses. The hydrocarbon fraction of biogenic gas consists predominantly of methane. The presence of as much as 2% of heavier hydrocarbons can be attributed to admixture of minor thermogenic gas due to low-temperature degradation of organic matter.
