摘要
本文系统地研究了云南可保等地的褐煤岩石类型、显微组合、煤化程度与液化性能之间的关系,提出液化的转化率随褐煤的煤化程度的增高而降低,且与褐煤的反射率及凝胶化程度有较好的相关性,这与褐煤的原始物质中的沥青质和孔隙度等因素有关。
Based on the test for the typical samples of brown coal taken from Kobao area in Yunnan province, this paper deals with the relation among lithotypes, macerals, maturity of brown coal and their behaviours of liquefaction. It is pointed out that the conversion yield of liquefaction decreases with increased maturity, and is closely related to the reflectance and golification. The results mentioned above are caused by the factors such as the primary bitumen substance and the porosity of brown coal and so on.
