摘要：

Asphaltenes, obtained by hydrogenation liquefaction of coal with different degrees of coalification, were separated by adsorption chromatography on silica gel with benzene and tetrahydrofurane elution into two fractions, and further by gel chromatography on a column filled with Bio-Beads SC-2 gel, into three fractions. The obtained subfractions were then evaluated by means of **1H-NMR spectroscopy; the results were used to compute the average structural parameters. Based on the results obtained, a standard procedure for the fractionation of asphaltenes obtained in hydrogenation liquefaction of coal is proposed.
