| 摘 要： | 通过显微组分测定、镜质组反射率测试、元素分析和工业分析、液氮吸附、透射电镜观察和等温吸附/解吸实验等，对沁水盆地南部高煤级变形煤的结构组成和吸附/解吸特征进行系统研究. 结果表明，1）高煤级煤随变形程度不同，其宏观、微观孔裂隙特征不同；2）高煤级变形煤的化学结构组成差异明显；3）高煤级变形煤吸附/解吸与煤岩物化结构组成的关系密切.

| Abstract: | Based on maceral determination, Ro test, ultimate-proximate analysis, LND, TEM, and adsorption/desorption test, composition and adsorption/desorption characteristics of deformed high-rank coals in the south of Qinshui basin were systematically studied. Results show that, 1) macro-and micro-pore fractures of high-rank coals change with the deformation degree; 2) chemical compositions of deformed high-rank coals show remarkably differences; and 3) the adsorption/desorption of deformed high-rank coals shows intimate relations with the physical and chemical compositions. |
