MANUFACTURING METHOD FOR MOLDED SOLID FUEL USING POROUS COAL AS STARTING MATERIAL

摘要

Provided is a manufacturing method for a solid molded fuel that can reduce the molding cost while maintaining the strength of the molded product. 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. Solvent oil is separated from the dehydrated slurry to obtain a cake, the cake is heated, and 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.
