The characteristics of carbonized woods of Pinus densiflora and Pinus koraiensis grown in different regions of Kangwon and Kyungbuk provinces were investigated for understanding charcoal quality. Wood samples were carbonized in an electric furnace under nitrogen gas flow (1kg/cm2) at the temperatures of 250°C, 300°C, 350°C, and 400°C. The characteristics of the carbonized woods such as weight loss, volume change, density, ash content, fixed carbon, and pH were examined. Structural change and crystalline properties were also observed by scanning electron microscopy and an X-ray diffraction method. The results showed that increasing carbonization temperature was resulted in an increase of weight loss and volume shrinkage. During carbonization, the woods with higher density had higher weight loss and volume shrinkage compared to the woods with lower density. Density reduction was not affected by treatment temperature due to balance reduction of weight and volume. Ash content, fixed carbon, and pH value increased with increasing the carbonization temperatures. While volatile matter decreased with an increase of carbonization temperature. Cell wall structure and crystalline properties were greatly changed by the carbonization temperature. It is revealed that the critical temperature for the change of cell wall structure and crystalline property must be around 350°C. Consequently, there were no significant differences on the quality of wood charcoal by the regions.
