Disclosed are apparatus and method for preparing carbon black, in which the carbon black may be continuously formed and activated. In one embodiment, carbon black powders formed in a combustion reactor are converted into a slurry which in turn is refluxed to the combustion reactor in a repeated manner, thereby to allow successive activation treatments. In this way, a sufficient residence time for the activation of the carbon black may be secured.
