Abstract
Hydrocarbonaceous material produced from pyrolysis of coal and shale is subjected to hydrogenation and fines removal by first passing it through an ebullating bed reactor in which the hydrocarbonaceous material is partially hydrogenated and partially vaporized. The vapor is then separated and further hydrogenated while the fines in the liquid portion are concentrated and removed as a slurry. The remaining liquid is vaporized, either by recycling it through the ebullating bed reactor or by flash evaporation, to rid it completely of fines. The thus vaporized remaining liquid is also subjected to further hydrogenation.
