发明名称 Production method for ashless coal
摘要 Provided is a production method for ashless coal in which there is no need to re-liquefy and form ashless coal. The production method for ashless coal comprises: an extraction step in which slurry obtained by mixing coal and a solvent is heated and a coal component that is soluble in the solvent is extracted; a separation step in which the liquid solution containing the coal component is separated from the slurry from which the coal component has been extracted; and an ashless coal capture step in which ashless coal is obtained by evaporating and separating the solvent from the solution separated in the separation step. In this production method for ashless coal, liquid ashless coal obtained in the ashless coal capture step by evaporating and separating the solvent from the solution is solidified into a predetermined shape by bringing the liquid ashless coal into contact with a solidifying means (water, for example).
