Research on the formed coke bond from coke fines

Coke fines were cold briquetted in presence of starch, MJ or SW as the binding agents, from which some optimum binders were selected for the molding of industrial waste coke fines in low temperature. The parameters, such as the binders´ ratio and molding pressure, were optimized to determine the suitable ones. Fired under high temperature previously, the resulting formed cokes were characterized of the compressive strength, ash content, volatile, moisture and so on. Simultaneously, the optimization of the constant heating time was conducted. The result shows that the optimum prescription of the binding agents is the SW, MJ, starch, water, with the addition of 1.5g, 2.00g, 0.38g, 10ml (20g coke fines), respectively. Furthermore, satisfying formed cokes can be prepared under a pressure of 150000N and kept for 5 hours under 1000°C, which seems feasible for industrial production for the inexpensive binding agents.
