NOVELTY - A fast-pyrolysis gasification synthetic system comprises a thermal-decomposition carbonization apparatus which manufactures carbon material and water vapor from source material containing water including carbon as main component and a hydrogen gas and water gas manufacturing apparatus which manufactures carbon monoxide from carbon material, and water vapor. Thermal decomposition carbonization apparatus comprises a source material supply portion (110), a thermal-decomposition portion (120), carbonization portion, and separation portion.    USE - System is used for fast pyrolysis and gasification of synthetic hydrous biomass.    ADVANTAGE - The fast-pyrolysis gasification synthetic system has simple structure.    DETAILED DESCRIPTION - A fast-pyrolysis gasification synthetic system comprises a thermal-decomposition carbonization apparatus which manufactures carbon material and water vapor from source material containing water including carbon as main component and a hydrogen gas and water gas manufacturing apparatus which manufactures carbon monoxide from carbon material manufactured using thermal decomposition carbonization apparatus, and water vapor. The thermal decomposition carbonization apparatus comprises a source material supply portion which supplies source material, a thermal-decomposition portion which supplies decomposed product connected with source material supply portion and thermally decomposes a source material at 150-350 degrees C by anoxic state to carbonization portion and comprising microwave heater, a carbonization portion which connects the thermal-decomposition portion, and separation portion containing a solid and gas separation device, a steam separator which is connected with the gas exit of solid and gas separation device, carbon material exit, water vapor exit, hydrogen gas exit and waste gas exit. The carbonization portion is equipped with high-frequency induction type heater, heats decomposed product supplied from thermal-decomposition portion at 350-600 degrees C under normal pressure and provides carbon material and gas component.
