为了保障甲烷氧化细菌生物反应降解煤层瓦斯实验的顺利进行,自主研发了高压气体混合装置,研究了在不同压力及有氧、无氧条件下,甲烷氧化细菌降解煤层瓦斯的规律和对煤吸附瓦斯性能的综合影响。通过对实验前后CH4和CO2的变化量进行检测、对比和分析,发现在1~5 MPa压力范围内,压力越大越有利于甲烷氧化细菌对煤层瓦斯的降解;压力相同时,有氧环境下的CH4减少量明显多于无氧环境下的CH4减少量。
In order to ensure the methane reaction of biodegradation of methane oxidative bacteria in coal seam, the high pressure gas mixing device was independently researched and developed. The law of methanogenic bacteria degradation of coal seam under different pressures and aerobic and anaerobic conditions was studied. The combined effect of performance. Through the detection, comparison and analysis of the change of CH4 and CO2 before and after the experiment, it was found that under the pressure range of 1 ~ 5 MPa, the bigger the pressure is, the more favorable for the degradation of methane gas by methane-oxidizing bacteria. When the pressure is the same, The reduction of CH4 is obviously more than the reduction of CH4 in anaerobic environment.
