Example Embodiment
[0016] Example 1
[0017] Take 20g mechanically crushed bagasse with a moisture content of 10-30% and place it in a 500mL round-bottomed flask, then add 50mL 98% concentrated sulfuric acid and stir quickly, then continuously pass ozone into the flask and stir continuously with a magnetic stirrer. It can be seen that the bagasse gradually turns black, expands in volume, and forms a loose and porous sponge-like carbon black. The carbon black obtained by the reaction was repeatedly rinsed with distilled water and dried at a constant temperature of 105°C. The dried carbon black can be pulverized by vibration mill, and can be classified by an ultrafine air classifier to obtain bagasse carbon black of different particle sizes.
