抄録

As the hydrogen enrichment operation is being considered in the blast furnace to reduce the CO₂ emissions. Since the ash behavior of coke is one of the factors that deteriorate the permeability and stability in the blast furnace, it is important to understand the degradation behavior of coke during the H₂O gasification process. In this study, in order to find the effect of temperature on degradation behavior between CO₂ gasification and H₂O gasification, gasification experiments were conducted in CO₂ and H₂O atmospheres at different temperatures in 20% reaction ratio. Moreover, to investigate the pore behavior, we used the SEM to observe the cross-section of cokes.
