The copreheated coal prepared under rather milder conditions (around 450 degree C within 15 min) exhibited better fusibility at the carbonization stage, providing a solid formed coke of high strength when carbonized in a vessel without moulding pressure at a low heating rate. In contrast, higher forming pressure and higher heating rate resulted in a expanded coke of low strength. Results suggest that the amount of volatile matter, its released rate at the carbonization stage and the size of pore after the forming, affect the fusibility and adhesion extent of copreheattreated coal particles in the carbonization stage. Fine grained mosaic anisotropy was developed in the whole cokes thus produced, of which CO//2 reactivities at 1000 degree C was low and comparable to that of a commercial blast furnace coke.
