| 摘 要： | 以钢渣为催化剂添加至焦煤中制备高反应性焦炭,研究碳溶反应温度对焦炭热态性能的影响及焦炭反应后的结构变化。结果表明,添加钢渣后,焦炭的反应性提高;随着碳溶反应温度的升高,焦炭的反应性呈线性增加,而反应后强度先缓慢降低然后迅速劣化;焦炭反应后的比表面积先增大而后减小。

| Abstract: | Slag,used as catalyst,is added to coking coal to prepare high reactivity coke. The influence of solution loss reaction temperature to the thermal properties of high reactivity coke and the change of coke structure after reaction are studied. The result shows that coke reactivity is improved with the addition of slag;coke reactivity increases linearly with the temperature rise of solution loss reaction,while the coke strength after reaction decreases slowly at first,then sharply;and the specific surface area of coke after reaction increases first and then decreases. |
