寺河矿无烟煤生物产气模拟

Simulation of Biogenetic Gas Generation of Anthracite in Sihe Coal Mine

为了研究无烟煤原始状态下的生物产气规律,以10 L玻璃发酵罐为装置,采用无烟煤块煤填料的方法模拟了寺河地区煤炭生物产气过程,检测了产气过程中产气量和产气前后煤质的变化。结果表明,无烟煤煤层水中产甲烷菌群能被激活,可利用无烟煤块煤中有机质来生长和代谢并产生CH4,提升煤层的含气量。

In order to study the law of biogenetic gas generation in the original state of anthracite, the 10 L glass fomenters filled with anthracite lump coal were used to simulate the process of biogenetic gas generation in the Sihe area. The gas production volume and the change of coal before and after experiments were tested. It was concluded that the methanogens in the coal seam could be activated and then consumed organic matter in anthracite lump coal for growth and metabolism of CH4, improving methane production.
