Results obtained from this study of hydrogenation of Synthoil and its fractions indicate the following: (1) Even under severe hydrogenation conditions where the aromatic saturation equilibria favor in the direction of complete saturation, coal-derived liquids showed marked resistance to complete hydrogenation. It was concluded, in line with the results obtained with model compounds, that the resistance to complete hydrogenation may be due to sterically hindered aromatic rings. (2) Hydrodenitrogenation was relatively more difficult when compared to hydrodesulfurization in coal-derived liquids. (3) The rate and depth of hydrodenitrogenation and hydrodesulfurization of coal-derived liquids may strongly depend on the steric characteristics of condensed N and S heterocyclic aromatic feed components, or of partially hydrogenated intermediates. (4) The asphaltene-preasphaltene fraction of Synthoil showed higher resistance to hydrogenation than the maltene fraction of Synthoil. (5) The solubility of the hydrogenated product of asphaltene-preasphaltene fraction of Synthoil in cyclohexane increased with decrease in H-aromaticity and heteroatom content. 5 figures.
