SUMMARY:Development of advanced H2 utilization technology for reduction of CO2 emission from blast furnace using 12 m3 experimental blast furnace.
DESCRIPTION:COURSE50, CO2 Ultimate Reduction System by Innovative technology for cool Earth 50, is the national project for reduction of CO2 emission from steelworks in Japan. Three steel companies, NIPPON STEEL CORP., JFE Steel Corp., and Kobe Steel Ltd, and one engineering company named NIPPON STELL ENGINEERING CO., Ltd. join this project supported by NEDO (New Energy and industrial technology Development Organization). The target of COURSE50 is reduction of CO2 emission from steel works by 30 %, 20 % by CCS and 10 % by operation of blast furnace. In order to realize the CO2 emission form blast furnace by 10 %, H2 utilization technology has been developing using 12 m3 experimental blast furnace. The experiments have been taking place form 2016. From 2016 to 2017, 10 % reduction of CO2 emission achieved by using three methods, gaseous reductant injection from tuyeres, gaseous reductant injection from shaft tuyeres, and high reducibility sinter ore charging. In order to improve the reduction CO2 emission technology, hydrogen-based gaseous reductants and high reducibility sinter were used form 2018. Two campaigns, 32 days each, were taken placed in 2018 and 2019. Three types of H2 concentrate gaseous reductants were injected. As a result, it is clarified that the reduction ratio of CO2 emission was affected by the H2 concentration. Over 10 % of CO2 emission was reduced with highest H2 concentration gaseous reductant injection.
