METHOD FOR PRODUCING ASHLESS COAL AND DEVICE FOR PRODUCING ASHLESS COAL

WIPO Patent Application WO/2018/216373

A1

The method for producing ashless coal according to an embodiment of the present invention includes: a step of heating a mixture of coal, a radical stabilizer, and a solvent; a step of eluting components soluble in the solvent from the coal in the slurry obtained in the heating step; a step of separating the slurry after elution in the eluting step into a liquid containing the solvent soluble components and solvent insoluble components; and a step of evaporating the solvent from the liquid separated in the separating step. The device for producing ashless coal according to an embodiment of the present invention includes: a heating unit that heats a mixture of coal, a radical stabilizer, and a solvent; an eluting unit that elutes components soluble in the solvent from the coal in the slurry obtained by the heating unit; a solid-liquid separating unit that separates the slurry after elution by the eluting unit into a liquid containing the solvent soluble components and solvent insoluble components; and an evaporating separating unit that evaporates the solvent from the liquid separated by the solid-liquid separating unit.
