In this work, a comparison between CO reactivity of lumps and briquettes made of two different binder and three different raw materials is presented. Experimental results on the prereduction behavior of such materials in 70% CO and 30% CO₂ atmosphere, heating rate of 0,17 K/s (10°C/min) at temperatures up to 1100°C are discussed. It was shown that briquettes presented higher CO reactivity, especially those whose molasses was the binder which had the highest reactivity. Level of oxygen also played an important role in CO reactivity. Comilog and Urucum with the highest oxygen level had highest reactivity while Assmang with the lowest oxygen level had the lowest reactivity between the raw materials. Porosity was a key variable to explain CO reactivity. Molasses briquettes had the highest porosity and the highest CO reactivity followed by bentonite briquettes and lumps.

在这项工作中，提出了由两种不同的粘合剂和三种不同的原料制成的团块和团块的CO反应性的比较。此类材料在70％CO和30％CO _2中的预还原行为的实验结果讨论了在高达1100°C的温度下0.17 K / s（10°C / min）的加热速率。结果表明，煤球具有较高的CO反应性，尤其是糖蜜为最高反应性的粘结剂。氧气含量在CO反应性中也起着重要作用。氧含量最高的Comilog和Urucum的反应性最高，而氧含量最低的Assmang的原料之间的反应性最低。孔隙率是解释CO反应性的关键变量。糖蜜型煤具有最高的孔隙率和最高的CO反应性，其次是膨润土型煤和块。
