“…5, in the case of catalyst no-addition coke, CSR(WL 20 %, CO 2 /COϭ50/50) increases with decreasing temperature in the temperature range of 1 000 and 1 200°C. Nishi et al 12) showed that the coke strength after reaction (CO 2 /COϭ100/0) that stopped at a weight loss of 20 % increased slightly with decreasing temperature in the same temperature range as in our study. Our study showed that a similar tendency was observed in the gas composition closely resembling that in the thermal reserve zone in a blast furnace.…”

“…Moreover, they attributed the high post-reaction strength of low CRI coke to the assumption that the coke reaction occurred preferentially on the surface of the coke and that of high CRI coke to the assumption that CO 2 enters the inner part of the coke, which disperses the reaction through the entire particle. This comment is different from the view by Nishi et al 11,12) and Yamaguchi et al 9) attributed this difference to a difference in the reaction condition; in Yamaguchi's study the reaction was conducted at an increasing temperature and in Nishi's study the reaction was conducted at a constant temperature.…”
