NOVELTY - A wood-type biomass liquefying system has water vapor turbine electric power generating system (1), cooling-heat electric power generating system (2), air separation system (3) and wood-type biomass ethanol manufacturing system (4). System (4) performs freezing and grinding of wood-type biomass chip (24), and fermentation, separation and concentration of ethanol by using vapor from system (1) and liquid nitrogen from system (3).    USE - Manufacturing ethanol (claimed) used as raw material for fuel of motor vehicle.    ADVANTAGE - The wood-type biomass liquefying system is economical and eco-friendly, and has high energy efficiency.    DETAILED DESCRIPTION - A wood-type biomass liquefying system has a water vapor turbine electric power generating system (1), a cooling-heat electric power generating system (2), an air separation system (3) and a wood-type biomass ethanol manufacturing system (4). The system (1) generates electric power by producing water vapor. The system (2) produces a refrigerant using the energy of steam-extracted vapor or exhausted vapor of system (1), and performs low-boiling point medium electric power generation. The system (3) cools air (16) by the refrigerant supplied from system (2), and produces liquid oxygen and liquid nitrogen. The system (4) performs freezing and grinding of a wood-type biomass chip (24), ethanol fermentation, ethanol separation and ethanol concentration by using vapor supplied from system (1) and liquid nitrogen supplied from system (3).    An INDEPENDENT CLAIM is also included for manufacturing method of ethanol, which involves performing freezing and grinding of wood-type biomass chip (24), ethanol fermentation, ethanol separation and ethanol concentration by using heat of vapor supplied from system (1) and cooling-heat of liquid nitrogen supplied from system (3).
