摘要： Provided is an ash-free coal production method that can produce an ash-free coal efficiently with a higher solvent recovery rate. The ash-free coal production method includes an extraction step of mixing coal with a solvent to give a slurry and heating the slurry to extract a solvent-soluble coal component; a separation step of separating a solution containing the coal component from the slurry containing the extracted coal component; and an ash-free coal obtaining step of separating and recovering the solvent from the separated solution to give an ash-free coal. The ash-free coal obtaining step includes a pressure-reducing substep of reducing a pressure to a level lower than the solvent vapor pressure to evaporatively separate the solvent from the solution to thereby give a solid ash-free coal; and a heating substep of heating the solid ash-free coal to evaporatively separate a residual solvent from the ash-free coal.

摘要： Provided is a method that controls and uniformizes fluidity of ash-free coal. The method includes the steps of obtaining an ash-free coal by removing a solvent from a solution containing a coal component dissolved therein (ash-free coal obtaining step (solvent recovering unit 8)); and mixing a plurality of coals of different types or components thereof, where the coals are capable of individually giving ash-free coals having different fluidities (mixing step (see reference signs B1 to B6)). The ash-free coal obtaining step (solvent recovering unit 8) obtains the ash-free coal by removing the solvent from the solution containing components of the coals which have been mixed.

摘要： A method for separating solvent-containing water, which is generated in the process for producing an ashless coal, into a solvent and water readily without using any adsorbent or the like (a solvent separation method). The solvent separation method comprises: a solvent-containing water supply step of supplying the solvent-containing water into a pressure vessel for solvent separation purposes; and a temperature retention step of retaining the temperature of the solvent-containing water that has been supplied into the pressure vessel for solvent separation purposes at a predetermined temperature (e.g., 100 to 180 DEG C. inclusive). In the pressure vessel for solvent separation purposes, water in the liquid form moves downward and the solvent moves upward due to the difference between the density of water and the density of the solvent at the predetermined temperature. In this manner, the solvent-containing water can be separated into the solvent and water.

摘要： 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.
