METHOD FOR PRODUCING ASHLESS COAL |
摘要 |
Provided is a method for producing ashless coal, said method comprising a slurry preparation step in which a slurry is prepared by mixing coal and a solvent, the coal that is included in the slurry is dewatered, and the temperature of the slurry is increased. The slurry preparation step comprises a preparation/dewatering step and a preparation/temperature increase step. In the preparation/dewatering step, preparation of the slurry and dewatering of the coal are performed by mixing coal and a liquid solvent that is circulated during a circulation step. In the preparation/temperature increase step, the slurry is prepared and the temperature of the slurry is increased by mixing the slurry with solvent vapor that is circulated during the circulation step. |
