PROBLEM TO BE SOLVED: To provide an inexpensive modified coal having excellent quality applied to a metallurgical coke raw material coal. A method for producing coke raw coal by modifying non-caking coal or caking coal, wherein the non-caking coal or caking coal is mixed with a non-hydrogen donating solvent to form a slurry, and the slurry Is heated to 300 to 420 ° C., and solvent extraction is performed. The heated slurry is separated into a liquid part and a non-liquid part, and the solvent is separated from the liquid part to obtain extracted charcoal. Coke raw material coal production method characterized by obtaining extracted coal. [Selection] Figure 1 |
