<P>PROBLEM TO BE SOLVED: To provide a method of manufacturing biomass coke usable in a domestic waste direct melting furnace or the like while reducing crushing power and molding power necessary to manufacture coke from biomass. <P>SOLUTION: The method includes a thermal decomposition process for separating the biomass into a thermal decomposition gas and solid carbonized matter at a temperature of 400-900°C by indirectly heating the biomass in an air-cut state; a gas reforming process converting a high boiling point liquid gas, which is contained in the thermal decomposition gas obtained by the thermal decomposition process and liquefied at normal temperatures and normal pressure, into low-boiling point gases, which are not liquefied at normal temperatures and normal pressure, such as hydrogen, carbon monoxide, and methane by a reforming reaction using a catalyst reacting at temperatures of 400-900°C; a gas purifying process for removing moisture, corrosive components and heavy metals in the gas by cooling and cleaning the reformed gas after reforming; and a pulverizing process for pulverizing solid carbonized matter obtained in the thermal decomposition process; and by a granulation process for adding a binder to the pulverized solid carbonized matter, pressurizing, molding and granulating them to manufacture the biomass coke. <P>COPYRIGHT: (C)2007,JPO&INPIT |
