Abstract of the Disclosure The invention relates to a method for hydrogenating coal whereby finely crushed coal is stirred into a slurry with a pasting oil. The slurry is pressurized and heated in heat-exchange with hydrogenation products from the top of a hot-separator, and then, by the application of external heat, to the hydrogenation scorching temperature. It is then subjected, in the presence of hydrogen, to catalytically- accelerated hydrogenation. Thus, the hydrogenation product is broken down in at least one hot-separator into a top-product in vapour form and a bottom-product containing a heavy, fluid- distillate oil, non-distillable components, and solids. In accordance with the invention, at least some of the distillate- oil, separated from the bottom-product in the hot-separator, is returned to the hot-separator.
