NOVELTY - A biomass-derived liquid fuel synthesizing apparatus has unit to gasify biomass, unit to compress gasified biomass gas, unit to supply compressed gas to heating container for pressure regulation which is provided with liquid fuel reaction tank filled with catalyst, unit to heat biomass gas supplied to tank using waste gas produced during gasification of biomass, unit to increase pressure of biomass gas supplied to container and tank using waste gas produced during gasification of biomass, unit to cool biomass liquid fuel synthesized in tank.    USE - Apparatus is used for synthesizing biomass-derived liquid fuel such as methanol.    ADVANTAGE - The apparatus is compact and has excellent operating characteristics. The biomass-derived liquid fuel is manufactured economically and efficiently at low temperature and low pressure using the apparatus.    DETAILED DESCRIPTION - A biomass-derived liquid fuel synthesizing apparatus has unit to gasify biomass, unit to compress gasified biomass gas to pressure of 0.7-1 MPa, unit to supply compressed biomass gas to heating container for pressure regulation which is provided with liquid fuel reaction tank filled with catalyst, unit to heat biomass gas supplied to liquid fuel reaction tank using waste gas produced during gasification of biomass to synthesize liquid fuel with favorable temperature, unit to increase pressure of biomass gas supplied to heating container and liquid fuel reaction tank using waste gas produced during gasification of biomass, to synthesize liquid fuel with favorable pressure, unit to cool biomass liquid fuel synthesized in the liquid fuel reaction tank and separate biomass liquid fuel and unreacted biomass, and unit to circulate and re-liquefy unreacted biomass gas which is separated by cooling, by recycling unreacted biomass gas to units which compresses and increases pressure of biomass gas.    DESCRIPTION OF DRAWING(S) - The drawing shows the schematic view of apparatus used for synthesizing biomass-derived liquid fuel. (Drawing includes non-English language text)
