We participate in a NEDO project called COURSE50 (CO_2 Ultimate Reduction in Steelmaking process by innovative technology for cool Earth 50), in which we aim to apply HPC as a caking additive to make strong coke for the iron blast furnace, which maximize the use of hydrogen as a reductant in order to minimize coke addition to the furnace. Coke gasification reaction by H_2O, the water-gas reaction, will be increased by increasing in the hydrogen reduction in the blast furnace. The influence of the water-gas reaction on coke strength after reaction was investigated in this study. The reaction rate of the water-gas reaction was estimated about three times to the coke gasification reaction by CO_2, the Boudouard reaction, but significant difference of the coke strength after reaction was not appeared in both after the water-gas reaction and the Boudouard reaction comparing at the same percent of the conversion. HPC additional coke performed to maintain higher strength after reaction due to the effect to form higher connectivity of coke matrix.
