<p>A method of processing solids-containing shale oils or tars which have been obtained by a dry distillation of oil shale or coal or by the gasification of coal or by the pyrolysis and extraction of tar sand, which method comprises hydrogenating, separating the solids, and a further processing by hydrogenation and distillation to produce automotive fuels. The method of the invention is characterized in that a shale oil or tar feedstock is hydrogenated in the sump phase at superatmospheric pressure and elevated temperature by a treatment with hydrogen in the presence of solids which consist substantially of coal, coke and inorganic components, and in the presence of naphthenecontaining hydrogenated oil used as a hydrogen-transferring medium or of catalytically active solids which have been added to the feedstock, As, Sb and other elements contained in traces in the liquid phase are removed therefrom by the hydrogenation, asphaltenes and heteroatoms contained in polar compounds are decomposed at the same time to decrease the polarity of the liquid product, and the liquid product is subsequently separated from the solids. The invention provides a simple, straightforward process of producing motor fuel in a high yield.</p> |
