<P>PROBLEM TO BE SOLVED: To provide a process of manufacturing biomass charcoal which can improve yield of biomass charcoal when biomass is carbonized to produce biomass charcoal. <P>SOLUTION: A process of manufacturing biomass charcoal is used for carbonizing biomass a to produce biomass charcoal i is characterized by having the processes consisting of carrying out the primary carbonization on biomass to obtain the primary biomass charcoal b and carbonized product, separating tar e from the carbonized product, mixing the primary biomass charcoal b with the separated tar e to obtain a mixture g, granulating the mixture g to obtain a granule h, carrying out the secondary carbonization on the granule h to obtain the biomass charcoal i in which the carbon content of tar e in the granule is adhered and deposited on the primary biomass charcoal b in the granule. Gas c is separated from the carbonized product, and the separated gas is burned to produce combustion gas j1, j2, which is preferably used as a heat source of carbonization. <P>COPYRIGHT: (C)2011,JPO&INPIT |
