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.
