72 高反応性コークスのCO_2ガス化反応による微視構造変化および触媒粒子の存在状態が強度に及ぼす影響(熱分解・コークス(2))

抄録

In this study, CO_2 gasification reaction type of highly reactive coke is experimentally measured and the effect of catalyst particles on the macro rigidly of highly reactive coke is numerically evaluated. CO_2 gasification reaction type in 900℃ imitated temperature of thermal reactive zone in blast furnace was converted from homogeneous reaction to topochemical reaction by addition of catalyst before coking. The macro rigidly of highly reactive coke is decreased by presence of catalyst particle, it seems to be caused by decrease of connection of coke matrix by inhibition of coal dilatation.
