A CORRELATION BETWEEN THE COALS OF DIFFERENT COAL-RANKS AND THE PYROLYTIC PRODUCTS FROM THE COAL-ASPHALTENES

摘要: 作者采用热解色相色谱(PY-GC)分析,对鄂尔多斯盆地不同煤级煤(Rmax°0.43～1.80%)及其沥青质热解产物组成进行了对比研究。研究表明,煤和煤沥青质的热解产物总体上基本相似,另外,由不同碳数区间的正构烷烃在不同热演化阶段的变化特征可知,煤沥青质在各演化阶段有不同的贡献。Abstract: The authors correlated the compositions of pyrolytic products between the coal-as-phaltenes and the coals of different coal-ranks (Rmax°0.43-1.80%), by means of PY-GC. The study shows that the pyrolytic products of the coals are generally similar to those of the coal-asphaltenes. Furthermore, in view of the changeable features of n-alkanes observed from different carbon number intervals at the different stages of thermal evolution, it may be clear that coal asphaltenes had contributed to various extents at the different stages of their evolution.
