摘要 通过对不同含氧官能团、烷基侧链及不同变质的煤结构模型对甲烷分子的吸附作用能的计算分析,结合煤结构、煤吸附等已有知识,很好的解释了干燥基和平衡水分的等温吸附实验条件下,煤对甲烷的Langmuir体积随煤级的变化规律及其差异;并指出煤分子结构是影响Langmuir体积随煤级变化的主要因素。 By the calculation and analysis of the interactions of CH4 with different coal structures, utilizing the knowledges of coal structure chemistry, coal adsorption theory, the varieties and diversities of the Langmuir volume with coal rank on the different conditions of air dried basis and equilibrium moisture isothermal adsorption experiments are explained, and coal molecule structure being the primary factor of the phenomenon of Langmuir volume with coal rank is put forward especially in this paper.
