Woody biomass is gasified with iron ore. The amounts of flammable gas products are not changed and only carbon dioxide are increased when iron ore exists. Iron ore in the residue of gasification reaction is almost reduced to metal iron. The amounts of tar and char are decreased at same time. Therefore, it is considered that iron ore is reduced by tar and char. When gasification of woody biomass is conducted under carbon dioxide atmosphere, the amount of carbon dioxide exhausted is lower than that of supplied. During gasification, carbon dioxide is reduced to carbon monoxide. This phenomena is important that this result means realization of negative emission. About 66% of iron ore is reduced to metal iron even under carbon dioxide atmosphere. More than 90% of energy of biomass is recovered when chemical potential of reduced metal iron is included.
