| description | To provide the method for producing the needle coke with an improved physical property by chemical treatment of a tissue, wherein the needle coke is used as an aggregate of graphite electrode formation used for electrodes in an electric furnace industry.SOLUTION: The method for producing the needle coke comprises: blowing again a calcined coke, that is produced by calcining raw coke produced by a delayed coking method at a temperature of 1200 to 1600°C with steam during a calcination process, converting selectively carbonaceous matter with an undeveloped needle-like tissue remaining in the calcined coke into hydrogen and carbon dioxide by a steam gasification reaction, removing the hydrogen and carbon dioxide, and leaving only a carbonaceous material with a developed needle-like tissue.SELECTED DRAWING: Figure 3
