摘要
The key feature of this method for refining low-rank coal is the feature of subjecting low-rank coal to a chemical reduction treatment. The key feature of this method for producing coke is the feature of producing refined coal using the method for refining low-rank coal and then carbonizing the refined coal. The key feature of this method for producing pig iron is the feature of producing coke using the method for producing coke, introducing the obtained coke into a blast furnace together with limestone and iron ore, and chemically reducing the iron ore. According to the present invention, it is possible to provide a method for refining low-rank coal, a method for producing coke and a method for producing pig iron which are useful for producing high strength coke at low cost.
