摘      要：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 *** binders,one from coal origin and other from oil origin were *** of coal-binder mixing ratio and base coal particle size on the fracture strength of composites was *** of binder with the coal particles at coal-binder interface and development of connected carbon matrix were primarily responsible for the strength of the carbonized coal *** trend of change in fracture strength as a function of coal-binder fraction was similar for both the ***,for same coal-binder mixing ratio,binder type strongly affected the maximum strength *** strength was found to be primarily dependent on the coal-binder mixing ratio and base coal particle *** main finding of this study is that the irrespective of binder type,for a given base coal particle size there was only one coal-binder mixing ratio at which the maximum strength was *** binder fraction at which the highest strength observed was correlated to the carbon matrix connectivity index.
