<P>PROBLEM TO BE SOLVED: To control fluidity of ashless coal, and to uniformize fluidity of the ashless coal. <P>SOLUTION: The method for producing the ashless coal includes: an ashless coal acquisition process (a solvent recovery device 8) to separate a solvent from a solution part in which components of the coal are dissolved and to obtain the ashless coal; and a mixing process (refer to symbols B1-B6) to mix two or more kinds of coal with fluidity after conversion into ashless coal different from one another, or to mix components of two or more kinds of coal with fluidity after conversion into ashless coal different from one another. The ashless coal acquisition process (the solvent recovery device 8) is a process to separate the solvent from the solution part including the components of the mixed two or more kinds of coal and to obtain the ashless coal. <P>COPYRIGHT: (C)2013,JPO&INPIT |
