Effect of binder amount on the development of coal-binder interface and its relationship with the strength of the carbonized coal-binder composite

Production of high-strength carbonized coal composites from non-caking coals only with possible application as coke is presented. A binder and a non-caking coal were mixed in different ratios and carbonized at 1000 °C to produce coal-binder composites. Two binders, one from coal origin and other from oil origin were used. Effect of coal-binder mixing ratio and base coal particle size on the fracture strength of composites was investigated....
