Abstract
Coal hydrogenation heavy oil consists of numerous complicated hydrocarbons and nonhydrocarbon compounds, consequently the elucidation of the chemical structure is extremely complicated and time consuming. Thus, the chemical structure of coal liquids have been investigated mainly to the present by means of **1H- and **1**3C-NMR techniques or a combination thereof. In the reported study a combination of dual-packed adsorption liquid chromatography (LC) and gel permeation chromatography (GPC) developed by the Bureau of Mines API project 60 for separation into compound types and further into their molecular size was employed for characterization of heavy oil obtained by coat hydrogenation. Experimental procedure is described and extensive data are presented and discussed.
