摘要：

We investigated the optimal heating conditions (heating rate, rapid heating temperature range, and pressure) and blending ratio that can produce high- strength coke by using formed coals containing biomass and modified-biomass. As a result, the coke strength was increased by broadening the rapid heating temperature range. Furthermore, it was found that the coke strength increased as the heating rate increased, with the optimal heating conditions being a heating rate of 40 degrees C/min and rapid heating temperature range of room temperature to 600 degrees C. When biomass was added to coal sample, the coke strength was degraded compared to the case of only coal even under optimal heating conditions. However, when modified-biomass was added, the degree of decrease in the coke strength was smaller, and there was a trend for the indirect tensile strength to increase with increasing pressure. The optimal pressure within the experimental range was 1 MPa. In addition, the coke with a high-strength of 6 to 12 MPa could be produced by increasing the modified-biomass blending ratio.
