低温煤焦油沥青质和胶质的分离与表征

对沥青质和胶质的分离与表征是低温煤焦油科学开发和综合利用的重要突破口之一。笔者借鉴原油三组分分离法将样品分离为沥青质、胶质和轻质组分3个组分，前两者的质量分数为53％～63％。由^1H—NMR谱图信息计算获得的结构参数可知，沥青质芳香度较高，芳香环缩合度较低，环烷烃含量较高，链烃含量较少；胶质芳香度较低，芳香环缩合度较高，环烷烃含量较少，链烃含量较高，碳链较长。

Separation and characterization of low temperature coal tar asphaltene and resin

Study of separation and characterization of asphaltene and resin plays an important part in developing and comprehensive utilization of low temperature coal tar. The sample was separated into three parts which were asphaltene, resin, light component based on crude oil three components separation method. The total quantity percentage of first two components is 53% - 63%. The ^1H-NMR indicate the structure of those two components, there are higher aromatic rate, lower aromatic nucleus, higher cyclanes contents and lower chain alkanes contents in the aphaltene; resin has lower aromatic rate, higher aromatic nucleus,lower cyelanes contents and higher chain alkanes contents.
