酸液改性煤的瓦斯吸附规律试验研究

Experimental Study on Gas Adsorption Laws of Acid Modified Coal Samples

  • 摘要: 为提高煤层气的采出率,通过酸液浸泡对煤样改性,利用高压压汞法对改性后煤样微观结构进行表征,并利用高温高压吸附仪对煤样瓦斯吸附规律开展试验研究。结果表明:酸液浸泡后煤样的退汞效率提高、总的孔容增加、比表面积减小,相应微孔的孔容比例和比表面积均减小;酸改性后的煤样吸附瓦斯量减少,即改性后煤样降低了瓦斯的吸附能力。
    Abstract: In order to improve coal bed methane production rate, coal samples were modified by acid soak to carry out experimental study in laboratory, then the micro-structure characters of modified coal samples were measured by high-pressure mercury injection method, and the gas adsorption laws of these samples were conducted by the high temperature and high pressure adsorption instrument. The results show that: after soaking in acid solution, the mercury withdrawal efficiency of coal sample is increased and the total pore volume is increased, specific surface area is decreased, the pore volume and specific surface area is decreased; the gas adsorption quantity of acid modified coal samples is reduced, and the modified coal sample reduces the gas adsorption ability.
