摘要： A method for producing an ashless coal includes an extraction step, a separation step and an ashless coal acquirement step. In the extraction step, a slurry obtained by mixing a coal with a solvent is heated and thereby a solvent-soluble component of the coal is extracted. In the separation step, the slurry is separated into a solution of the solvent-soluble component of the coal and a solid content-concentrated liquid. In the ashless coal acquirement step, an ashless coal is obtained by evaporating and separating the solvent from the solution. The solvent is a mixture of a dissolution medium and a coal extraction accelerator added thereto. The solvent contains a bicyclic aromatic compound that is liquid at ordinary temperature. The coal extraction accelerator containing no nitrogen has two benzene rings and has at least one cyclic structure having no double bond.

摘要： A method for producing an ashless coal which includes a slurry preparation step, an extraction step, a separation step, an ashless coal acquirement step, and a by-product acquirement step. The separation step is conducted under the state of being pressurized to a pressure equal to or higher than a vapor pressure of the solvent. In the by-product acquirement step, the solvent is evaporated and separated from the solid content-concentrated slurry by spraying the solid content-concentrated slurry into a flash tank in which a pressure is set to lower than a saturation pressure of the solid content-concentrated slurry from a spray nozzle while maintaining a pressure of the solid content-concentrated slurry in a nozzle orifice of the spray nozzle at a level equal to or higher than the vapor pressure of the solvent.

摘要： A production apparatus of an ashless coal includes a preheater, an extraction tank, a feed pipe, a solid-liquid separator and a solvent separator. The preheater heats a solvent. The extraction tank extracts a coal component soluble in the solvent from a slurry including a mixture of a coal and the solvent heated by the preheater. The coal feeding unit feeds the coal to the feed pipe by pressuring a feed part to the feed pipe such that the solvent does not flow back. The solid-liquid separator separates a solution part containing the coal component from the slurry. The solvent separator evaporates and separates the solvent from the solution part to obtain an ashless coal.

摘要： In a method for producing residue coal according to the present invention, a solvent is separated by evaporation from a solid material concentrate, which has been separated in a gravity settling vessel (7), in a solvent separator (10), thereby producing a residue coal mixture in which the solvent is remained in the residue coal. Subsequently, the remaining solvent is separated by evaporation from the residue coal mixture in a drier (11), thereby producing the residue coal. In the drier (11), the remaining solvent is separated by evaporation from the residue coal mixture utilizing a heat the residue coal mixture itself has. In this manner, an apparatus for drying the residue coal mixture can be simplified, and the cost required for the drying can be reduced.
