Abstract
<p>Formed samples with a weight ratio of caking coal : slightly-caking coal : non-caking coal = 15:45:40 were first heated rapidly to 450-600°C at 10-40°C/min under pressure in a stream of pure He, and the temperature was then increased to 800°C at a slow heating rate of 3°C/min under ambient pressure. When the temperature range of the rapid heating was increased from room temperature-450°C to room temperature-600°C, the adhesiveness between coal particles increased and the strength of the resulting coke increased significantly. In addition, the strength of 800°C coke tended to increase with increasing the rapid heating rate. Furthermore, the strength tended to be higher at larger pressure, and the optimum pressure was 1 MPa under the present conditions.</p>
