ABSTRACT A novel carbonaceous material derived from solid carbonaceous fossil fuel, in particular low rank coal, such as brown coal, having a low ash and sulphur content, is prepared by deoxygenation and dewatering in the presence of hydrogen and a sol- vent having hydrogen carrier properties (e.g. anthracene oil under conditions known per se for the solvent extraction of coal.) The entire lique- form reaction product is distilled down without prior filtration and recovered as the product which, besides the soluble components also includes the ash and carbonaceous insolubles. The material which has a ring and ball softening point above 30°C, pre- ferably above 100°C, is particularly useful for blending with coal having inferior coking properties in order to produce a coking blend useful for the production of metallurgical coke, applying conven- tional coking conditions.
