NOVELTY - Biomass is converted to charcoal, and smoke produced during conversion is introduced to preliminary fractional distillation device (14). The smoke containing organic substance is cooled and liquefied at temperature T1 (16). The remained smoke is introduced to fractional distillation device, and cooled and liquefied at temperature T2. Fractional distillation liquid having boiling point (T2-T1) is obtained.    USE - For carbonization and fractional distillation of biomass such as chaff, waste material, timber and wood.    ADVANTAGE - The carbonization and fractional distillation method effectively removes benzopyrene from hot smoking produced during conversion of biomass.    DETAILED DESCRIPTION - A biomass is converted to charcoal in a carbonization furnace (12), using reduced supply of oxygen. The smoke produced during the conversion of charcoal, contains several organic substances. A preliminary fractional distillation device (14) is arranged between carbonization furnace and fractional distillation device (16). Smoke produced from the carbonization furnace, is introduced to preliminary fractional distillation device. The smoke is cooled and liquefied at a temperature T1 which is less than the boiling point of benzopyrene. The remaining smoke is introduced to fractional distillation device. The smoke is cooled and liquefied at temperature T2 which is less than temperature T1. The benzopyrene is removed substantially, and fractional distillation liquid having boiling point (T2-T1) containing organic substance, is obtained.    INDEPENDENT CLAIMS are included for the following:    (1) fractional distillation liquid; and    (2) repelling charcoal.
