ABSTRACT:
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 extruder in front of the end of the screw. From the reaction product leaving the extruder hydrocarbons which are fluid under normal conditions are separated.
Part of these hydrocarbons which are liquid under normal conditions may be recycled to the extruder.
