摘要
本文分别叙述了以现代植物(干草)、现代淤泥、第四系泥岩与泥炭、前第四纪褐煤为原料,进行微生物厌氧分解产气的设想、方法、装置以及气体的测定和成分分析的结果。指出生物生气是长期持续的不平衡过程。讨论了生气量与有机母质埋藏年代的定量关系,为生物气生气量估计提供依据。根据系列气样中甲烷δ^(13)C迅速变轻的事实,解决了勘探生物气时同位素指标偏轻和地表沼气δ^(13)C偏重的矛盾。
Recent plant (dry grass) and mud, Quaternary mudstone and turf, Pre-Quaternary brown coal are used to study the various aspects of gas generation by anaerobic microorganism decomposition, including the asumpt-ion, method, device and results of composition analysis. It is considered that the gas generation of organism is the result of continuous unbalance over a long period of time. The quantitative relation between the amount of generated gas and buried age of organic matter is also discussed, which provides evidence for the estimation of the amount of generated biogas. Based on the fast lightening of methane δ13C in the gas sample series, the contradiction between the lighter isotopic index and the heavier surface methane δ13C in biogas exploration can be solved.
