摘　　要：基于13个镜质组最大反射率小于0.65%的低煤级煤样平衡水条件下的高压等温吸附实验,分析了低煤级煤的朗格缪尔常数与平衡水分、煤级、显微煤岩组分、比孔容和比表面积之间的关系,揭示了低煤级煤的吸附特征与中、高煤级煤之间的差异,探讨了低煤级煤的吸附机理。Based on isothermal adsorption experiments under equilibrium moistures and high pressures on 20 low rank coal samples whose reflectance's of vitrifies are less than 0.65%, the relationships of Langmuir volumes, Langmuir pressures between equilibrium moistures, coal ranks, macerals, special hole volumes and special surface areas are respectively discussed. The difference of isothermal adsorption characteristics between the low rank coal and the middle, high rank coal is revealed, and adsorption mechanism of the low coal rank is discussed.
