Effects of CaO Addition on the Reactivity and Reaction Kinetics of Coke
In recent years,researches have shown that highly reactive coke for blast furnace ironmaking not only reduces fuel ratio but also reduces carbon emissions.Therefore,the research on developing high reactivity coke has received attention.In this work,CaO was added into coals with different degrees of metamorphism to caking coke,and then,the effect of CaO addition amount on the reactivity and post reaction strength of coke was systematically investigated.The non-isothermal gasification reaction behavior of coke with different amounts of CaO and CO2 was studied at different heating rates,and the influence of CaO on the characteristic parameters of coke gasification reaction and the kinetic process was analyzed.
