Document Type and Number:
WIPO Patent Application WO/2014/174985
Kind Code:
A1
Abstract:
This method comprises: a pulverization step for pulverizing low-grade coal; a mixing step for obtaining a slurry by mixing said pulverized low-grade coal and a solvent oil; a dehydration step for obtaining a dehydrated slurry by heating and dehydrating said slurry; a solid-liquid separation step for obtaining a cake by separating said solvent oil from said dehydrated slurry; a drying step for obtaining powdery modified coal by heating said cake and further separating said solvent oil from said cake; and a molding step for pressurizing and molding said powdery modified coal by using a molding machine, without the addition/mixture of a binder. In said molding step, a coolant is sprayed onto the surface of said molding machine, and the surface temperature of said molding machine is kept equal to or below 100°C.
