A granular conductive carbon black and a preparation method thereof, belonging to the technical field of conductive carbon blacks. The method for preparing a granular conductive carbon black includes making a raw material of the conductive carbon black undergo moistening with water of a temperature of 80 C. or higher, performing wet granulation and drying in sequence. The raw material of the conductive carbon black is infiltrated by the water of a temperature of 80 C. or higher, so that the hydrophilic property of the raw material of the conductive carbon black is enhanced, the water of a temperature of 80 C. or higher enters the microporous structures of the raw material of the conductive carbon black, then a good moistening effect is achieved, and further the granular conductive acetylene carbon black with uniform particle size distribution is prepared through wet granulation and drying.

The present invention relates to a method for oxidizing a carbon black which can prevent or alleviate change in the surface oxidation degree of the carbon black by a residual ozone after surface oxidation reforming, and a method for preparing the carbon black by comprising it in a single continuous process.
