【摘要】 根据我国若干地区褐煤中镜煤质含量较高及沥青收率较低的特点,本工作从煤的岩相-化学观点,研究了广西百色褐煤镜煤质的显微结构特征与化学性质间的联系.结果指出,百色褐煤镜煤质可以区分为各种结构类型,其中,木质结构镜煤和凝胶化基质为主要组分.木质结构镜煤和凝胶化基质,不仅在显微结构上不同,而在腐植酸和沥青的含量和性质上,也均有较显著的差别.据此,作者讨论了影响百色褐煤化学性质的某些因素.更多还原

【Abstract】 Most of the Chinese lignites are characterized by their higher content of vitrinite and lower yield of bitumen.The microstructure and chemical properties of the vitrinite of the Baise lignite have been studied, and an attempt on their correlation has been made. It is shown that the vitrinite of the Baise lignite can be distinguished microscopically into various types, of which xylo-telinite and collinite-cement are the primary constituents. Xylo-telinite is not only distinct in microstructure from collinite-cement, but also their humic acid and bitumen contents and properties are quite different from one another.Based on the results obtained, the factors that have influence on the chemical properties of the Baise lignite have been discussed.更多还原
