摘要：
Coal extraction produces large amounts of wastewater containing coal powders, which could be used to produce coke. In this case, binder materials should be used to allow compression capacity to the mixture. This work aims to study the effect of binder addition in mixtures of coals containing different contents of coal powders to obtain coke. Compositions containing different amounts of coal powders were prepared by varying the nature and the contents of the binders to allow the pressing of powders. Study of the thermal behavior of these compositions was performed. The composition that showed the best results was then homogenized, pressed and heat treated. The final composition showed FSI about 4.5 and compressive strength of 5 MPa, demonstrating high potential for coke production from coal powder.
