摘　　要：近年来,研究表明利用高反应性焦炭进行高炉炼铁不仅可以降低燃料比,而且可以降低碳排放。因此,开发高反应性焦炭的研究受到关注。本工作在不同变质程度煤中添加CaO进行炼焦,研究CaO添加量对焦炭反应性和反应后强度的影响。同时,研究添加不同含量CaO的焦炭在不同升温速率下的焦炭与CO_(2)非等温气化反应行为,分析了CaO对焦炭气化反应特征参数以及动力学过程的影响规律。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 CO_(2)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.
