Preparation of pelletized coke by cocarbonization of
It was found that the optimum CC preparation temperature was 250 °C (CC250) for high strength coke preparation. 4. Whereas increasing the blending ratio of CC250 to cakingcoal decreased the coke strength, the extent of the decreasing strength was smaller than that of slightlycaking coal or pyrolyzed char blended with caking coal. 5.
