- Pyrolytic Behavior of Pine Wood Dust-

To extend the understanding of the pyrolysis mechanism of wood, we have investigated wood dust charcoal and con-densate of volatile organic compounds (VOC) obtained during the pyrolysis of red pine (Pinus densiflora Sieb. et Zucc.) at 180∼450°C using elemental analysis, IR and GC/Mass. The effect of activation process on the charcoal structure also has been studied by comparing elemental analysis and IR data of charcoal carbonated at 600°C and char-coals activated at 750°C. The results show that pyrolysis of wood has mainly started near at 240°C and its chemical 가열처 리 및 탄화처 리 소나무재(Pinus densiflora Sieb. et Zucc.) 의 구 조 및 물리⋅화학 적 특성() 267 components did not changed much up to 270°C. However, the element contents and IR spectra drastically changed at 300°C. The fact that IR peaks related to the aromatic ring of lignin are observed in the charcoal pyrolized at 450°C indicates that a small part of lignin still remains at this temperature. The chemical structure of the activated charcoa
