Abstract:
Provided is an ash-free coal production method without the need to once re-liquefy and form an ash-free coal. The ash-free coal production method includes an extraction step of mixing coal with a solvent to prepare a slurry and heating the slurry to extract a solvent-soluble coal component; a separation step of separating a solution containing the solvent-soluble coal component from the slurry obtained from the extraction step; an ash-free coal obtaining step of evaporatively separating the solvent from the solution separated in the separation step to obtain an ash-free coal. The ash-free coal obtaining step in the production method is performed so that the solvent is evaporatively separated from the solution to give a liquid ash-free coal, and the liquid ash-free coal is brought into contact with a solidifier (e.g., water) to solidify into a predetermined shape.
