摘　　要：煤的溶剂精制法乃源自Bergius直接液化法,通过缓和的热分解和轻度加氢,可制备分子结构十分接近于煤的液体产品。借助溶剂精制煤的分子组成及其结构的研究,可以推测煤中某些单元或碎片的结构,便于指出其有效利用的方向,这便是本研究的基本构思。Two solvent refined coals(SRC/s)are prepared by hydrogenative liquefaction of a weakly caking coal and a cannel coal. These two SRC samples are fractionated into subfractions according to molecular functionality using Farcasiu's sequential elution by solvents chromatography (SESC) procedure and subsequently UV detection. The elemental compositions and VPO molecular weights of separated subfractions are measured. The compositional distinction between the two SRC's and the nature of solvent refining processes are discussed.
