EFFECT OF WOODY BIOMASS ON REDUCTION BEHAVIOR OF IRON OXIDE

摘要

CO_2 emissions in steel works accounts for about 15% of those in Japan (2011), and most of those are from blast furnace iron-making process. To reduce CO_2 emissions, utilization of woody biomass in blast furnace process is considered. Woody biomass has the characteristic of carbon neutral, as well as high reactivity. CO_2 emissions can be reduced by the use of woody biomass as coke substitution because of its characteristic of carbon neutral.
