PROBLEM TO BE SOLVED: To provide a method for producing a carbon black having improved aggregate distribution characteristics, a high surface area, and high structure characteristics and an apparatus therefor. SOLUTION: A flat type spray apparatus is used for enhancing the contact efficiency between a high-temperature gas flow and a raw material hydrocarbon and for simultaneously homogenizing the reaction field in the carbon black formation reaction; and the spray angles of raw material introduction α, βare each set in a specified range. |
