Claims10
A method for oxidizing a carbon black, comprising:
- the steps of:
- (a) generating ozone from oxygen in an ozone generator to obtain a mixed gas of oxygen and ozone;
- (b) introducing the mixed gas into an oxidation reactor having each of an inlet and an outlet to oxidize a carbon black in the oxidation reactor;
- (c) discharging the mixed gas through the outlet in the oxidation reactor;
- and (d) removing the ozone remaining in the oxidized carbon black.
