BIOMASS ENERGY CONVERSION SYSTEM AND BIOMASS ENERGY CONVERSION METHOD

WIPO Patent Application WO/2022/231014

A1

[Problem] To provide a biomass energy conversion system and a biomass energy conversion method that decrease the amount of carbon dioxide discharged and effectively utilize the residue generated by biomass power generation to achieve good energy conversion efficiency. [Solution] A biomass energy conversion system 1 has: a subcritical water treatment unit 22 that reduces the molecular weight of a biomass starting material 10 in the subcritical region; an extraction unit 23 that obtains a dry distillation gas by carbonizing the biomass starting material 10 reduced in molecular weight, and extracts pyroligneous acid 12 and wood tar 13; a power generation unit 25 that generates power using the dry distillation gas as a starting material; a combustion furnace 6 that combusts the wood tar 13; a humic solution generation unit 4 that generates a humic solution 14 by impregnating an organic substance with the pyroligneous acid 12; and a dissolution unit 8 that recovers at least some carbon dioxide generated from the power generation unit 25 and the combustion furnace 6, and dissolves the same in the humic solution 14.
