The present invention is provided with a step for preheating coal, a step for heating an extraction solvent, a step for mixing the preheated coal and the extraction solvent heated to a higher temperature than the preheated coal and thereby heating the coal, a step for separating a solution in which a coal component is dissolved from the mixture of the coal and the extraction solvent, and a step for evaporating and separating the extraction solvent from the solution.

Method for manufacturing ashless coal

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.

Carbon dioxide sensor

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.

Ashless-coal production device, and ashless-coal production method

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.

Ashless coal production method

A method for producing an ashless coal includes a slurry preparation, an extraction, a separation, an ashless coal acquirement, and a by-product acquirement. In the by-product acquirement, a solvent used in the slurry preparation is evaporated and separated from a solid-content concentrated liquid separated in the separation, and then, a by-product coal is acquired. The by-product coal is used as a fuel for heating a slurry obtained in the slurry preparation.

Method for producing ashless coal

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.

Ash-free coal production method

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)); 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 Bto B)). The ash-free coal obtaining step (solvent recovering unit) obtains the ash-free coal by removing the solvent from the solution containing components of the coals which have been mixed.

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.

A main body part and a nozzle part which is connected on the downstream side of the main body part and extends horizontally are provided in the supply pipe. A plurality of holes are provided in the nozzle part. By virtue of this, agitation of the solid-content concentrated liquid which has settled in the bottom is inhibited.

An opening mechanism has a guide mechanism which holds the movable body in such a manner as to be slidable in the predetermined direction with respect to the planar solid body. This structure allows the solid body, the movable body and the guide bodies to be made of planar materials such as a steel plate, thereby enabling the opening mechanism to have a thinner profile. In addition, these components can be produced by a comparatively simple process such as press working, making it possible to provide a less expensive opening mechanism. A thin electronic device using this opening mechanism is also provided.
