Title:
APPARATUS AND METHOD FOR PREPARING CARBON BLACK
Document Type and Number:
Japanese Patent JP2020084193
Kind Code:
A
Abstract:
To provide: an apparatus for preparing carbon black in which a separate reforming reactor for reforming carbon black (especially, activation for increasing a specific surface area thereof) is not required, but the reforming treatment of the carbon black can be continuously performed in a combustion reactor to form existing carbon black; and a method for preparing carbon black using the same.SOLUTION: An apparatus for preparing carbon black comprises: a combustion reactor 110 to form carbon black powders; a mixer 140 located downstream of the combustion reactor, the mixer being configured to mix the carbon black powders formed in the combustion reactor and a dispersion medium with each other to form carbon black slurry; and a reflux unit 150 located downstream of the mixer, the reflux unit being configured to reflux the carbon black slurry formed in the mixer to the combustion reactor.SELECTED DRAWING: Figure 1
