摘要
煤具有较大的比表面和较强的吸附甲烷气体的能力,而等温吸附曲线是描述在一定条件下煤对气体的吸附(解吸)的能力、进行煤层地质评价、试采措施及储量评估的重要资料。文章结合目前国内各位学者对煤层气吸附机理研究的各种资料,从实验角度,研究两种不同实验条件下煤的吸附性能,并对煤岩等温吸附测试的实际操作方法做了进一步的探讨。
The coal has high specific surface area and strong adsorption of methane gas ability. The adsorption isotherm is important material using for describe under certain conditions of coal gas adsorption/desorption ability, geological evaluation of coal seam, exploration measures and reserves evaluation. Combining with the study on the mechanisms of coal bed methane adsorption, through experiments of draw adsorption isotherm, We made research on the adsorption properties of coal under two kinds of different experimental conditions, and further discussed the actual operation method of test of coal isothermal ndsorption.
