Abstract:
Four blast furnace steel makers and one engineering company in Japan have been engaged in the “CO2 Ultimate Reduction in Steelmaking Process by Innovative Technology for Cool Earth 50 (COURSE50) Project”, since FY2008. This project is a National Projects commissioned by New Energy and Industrial Technology Development Organization (NEDO).
The target of COURSE50 is a reduction of approximately 30% in CO2 emissions in the steel manufacturing process. Two technologies, which are a) Reduction of iron ore by using hydrogen-amplified coke oven gas to curb CO2 emissions from blast furnaces, and b) separation and recovery of CO2 from blast furnace gas by effective utilization of unused waste heat in the steel works are investigated.
