In this study comparative results of thermogravimetric (TG) and differential thermal analyses (DTA) of hardwoods (e. g. nara, kashi and buna) and conifers (hinoki and sugi) have been stated. According to the differential thermogravimetric (DTG) analysis curve, a distinct two stage reactions occur for hardwoods. The differences in pyrolysis characteristics of above two types of wood have also been illuminated. The yield of charcoal from conifer is higher than that from hardwoods. The ignition characteristics of hardwoods are close to the binchoutan. The electrical resistance of charcoal reduces to almost zero at and over 900℃. Finally an attempt is taken to produce charcoal from the compressed mixed wood (wood chips, 60% + dead leaves, 40%). The charcoal yield from mixed wood is higher than that of original wood chips. Wood chips and dead leaves may be used efficiently for charcoal production.
