A coal-liquefying method wherein a hydrocarbon oil is obtained from coal comprises the steps of supplying coal and water or coal, water, and an oil into a molten metal at 300 to 800<o>C, and cooling the gases produced by the catalytic reaction between these materials in the molten metal, to obtain separate liquefied components. Also disclosed is an apparatus employed for this liquefaction of coal. The coal-liquefying apparatus comprises a reaction vessel containing the molten metal; a supply machine supplying the material being processed, the machine being positioned above the reaction vessel; an extraction pipe for drawing out the gases produced, the pipe also being positioned above the reaction vessel; a rotary shaft which is provided above the surface level of the molten metal in the reaction vessel; and a raking blade which is provided on the rotary shaft to force the material being processed into the molten metal, so that it is possible to force the material into the molten metal by the raking blade, simply by dropping the material onto the surface of the molten metal. |
