PROBLEM TO BE SOLVED: To provide a manufacturing method for a solid molded fuel that can reduce the molding cost while maintaining the strength of the molded product. SOLUTION: A mixed oil that includes a heavy oil and a solvent oil, and a porous coal are mixed to obtain a slurry. The slurry is dehydrated by heating to obtain a dehydrated slurry. The solvent oil is separated from the dehydrated slurry to obtain a cake, the cake is heated, and the solvent oil is additionally separated from the cake to obtain a modified coal. Moisture is added to the modified coal to obtain a moist modified coal with a moisture content of 3-10 wt.%, and then the moist modified coal is molded under pressure. COPYRIGHT: (C)2010,JPO&INPIT |
