Abstract
Recent research progress on coke reactivity and its control are discussed. Based on a review of coke behavior in a blast furnace, the importance of increase in coke reactivity in the temperature range of <1127K is emphasized. The rate of the reaction between coke and CO2 is affected by carbon structure, heating conditions and catalyst, and its effect on coke degradation is also discussed. Research interests and application of highly reactive coke and its contribution to the realization of highly effective blast furnace operation are also mentioned.
