| Abstract Scope |
Coke is essential to the ironmaking and steelmaking industries. However, the coking coal resource is scarce. Therefore, it is expected to improve the coke quality through novel coking technology. Superior quality coke with low reactivity and high strength is beneficial for saving fossil energy and reducing carbon emissions. Hot tamping coking is a promising technique to produce superior quality coke. The tamping operation is conducted when the coal material undergoes the plastic stage in the pyrolysis process. The results of our work show that the post-plastic stage is most appropriate for conducting the hot tamping operation. After conducting the hot tamping with proper temperature, stress and holding time, the coke reactivity can be reduced by 9.7 % and the crushing strength could increase to 1.8 times when compared with coke without hot tamping operation. |
