摘要
了解寺河矿区产甲烷菌群对不同阶煤的降解产气能力。分别以褐煤、肥煤和无烟煤为实验对象,展开煤炭生物成气实验。实验结果显示:寺河矿区产甲烷菌群能够较好地降解煤产气,且相比于变质程度更高、煤阶更高的无烟煤,煤阶较低的褐煤可产生更多的甲烷气体,并具有产甲烷初始时间提前、产气周期更长等特点。
To understand the capacity of the methanogenic community degrade diifferent rank coals into methane in Sihe district,with lignite,metabituminous and anthracite coals as the experimental objects, the biological conversion of coal to methane progress was analyzed.The results indicated that the methanogenic community in Sihe district can degrade coal into methane,and more methane gas was produced with low rank coal than high rank coal.Meanwhile,the methane production cycle was longer using lignite coal in comparison with high rank coal.
