Abstract
In this study, effects of dispersion state of caking additives in coal blends on coke quality were evaluated. Asphalt pitch (ASP) was used as caking additives. The dispersion state was controlled by regulating the moisture content of coal and ASP before blending each other. As the caking additives dispersed, the indirect tensile strength of obtained coke became higher. In addition, the roundness of coke pores became higher and the large coke pores whose diameter was more than 1 mm decreased according to image analysis. It was therefore suggested that the coke strength was enhanced with increase of the dispersion because of the change of pore structure.
