Abstract
PURPOSE: To obtain a coke high strength, by mixing a specific amount of a bituminous material with a fine granular coal prepared by removing a fine particulate coal froma pulverized dust coal, charging the resultant mixture into a coke oven, and carbonizing the mixture.
CONSTITUTION: A fine particulate coal having a particle size preferably ≤0.1mm is removed from a pulverized dust coal by the pneumatic classification, etc., and 1W15wt% bituminous material is mixed with the resultant fine granular coal. The mixture is then charged into a coke oven, and carbonized preferably under a load to give the aimed coke. The bituminous material having a ratio (H/C) of 0.05W1.90 and a softening point <300°C is used. The moisture content in the dust coal is preferably adjusted to <6wt%.
