<p>The invention relates to a method for producing fuel from solid bituminous or lignocellulosic material. The material is charged, optionally continuously, to a closed vassel togehter with oil heated to a temperature in excess of 65.degree.C, preferably in excess of 75.degree.C. A total gas pressure of 5 - 50 kPa is maintained in the vessel. The material and oil are removed from the vessel, optionally also continuously, and separated by mechanical means, for example by means of rolls, to press the oil from the material. The separated oil is returned to the process.</p> |
