The common method for obtaining iron from the iron ore is iron oxide reduction by using coke. Currently, coke production in Japan relies on importation of coal from foreign countries. Under this situation, the price of coal has been rising in recent years and further increase in price is expected in future. Therefore, in order to reduce the amount of coal consumption and in consideration of the future energy demand, it is important to consider some alternative coal resources. In this study, we target on the use of woody biomass as an alternative raw material for production of coke. We have co-carbonized mixtures of coal, wood biomass and lignin in various mixing ratio by using an electric furnace. To evaluate the suitability of the coke produced from woody biomass, we have examined its binding properties by using optical microscope.
