    摘要: This method of producing modified coal comprises a step for dehydrating low-grade coal, a step for adding water to the dehydrated coal, a step for agglomerating the water-added coal, and a step for slowly oxidizing the agglomerated coal. In the water addition step, the amount of water added is adjusted so that the water content in the water-added coal is 5 to 20 mass%, and in the oxidation step, the agglomerated coal is held at a temperature of 70 to 105°C in air. The water content of the oxidized coal after the oxidation step is preferably 1 to 13 mass%. The oxidation step may also be followed by a step for pulverizing the oxidized coal and a step for secondarily adding anti-dusting water to the pulverized coal.
