A b s t r a c t. Coal is continuously fed into an extruder and reacts therein at elevated pressure and temperature and possibly in the presence of a catalyst with hydrogen and/or hydrogen containing compounds added to the contents of the extruder on at least one spot situated at a distance of at least three times the inner diameter of the ex- truder in front of the end of the screw. From the reaction product leaving the extruder hydrocarbons which are fluid under normal con- ditions are separated. Part of these hydrocarbons which are liquid under normal con- ditions may be recycled to the extruder.
