煤直接液化全馏分油组成复杂，深入认识煤直接液化油化学组成时，一般要分离成饱和烃、芳烃、胶质等不同的族组分，然后再对每一组分进行详细的分析表征，周相萃取是快速、高效分离油品族组成的方法之一。根据煤直接液化全馏分油的特点，重点研究了固相萃取法分离煤直接液化油族组成时，同相萃取材料与样品重量比、饱和烃洗脱溶剂加入量、溶剂洗脱速率等对煤直接液化油中饱和烃和芳烃组分分离效果的影响，获得了最佳分离条件。

The composition of full distillates obtained by direct coal liquefaction is very complex, the different components including saturate, aromatic, resin etc, should be separated firstly and then each component should be identified with detailed methods for in-depth understanding of the chemical composition of the distillates. Solid phase extraction (SPE) is one of the fast and efficient methods to separate the full distillates. Based on the characteristic of fult distillates made by directly liquefying coal, emphatically studied the influences of SPE materials and sample weight ratio, saturate eluting solvent dosage as well as solvent elution rate on the separation effects of saturate and aromatic components in the full distillates, and obtained the optimum separation conditions.
