Study on Optimal Condition of Activated Carbon Prepared by Microwave Heating from Shot Coke

Abstract:

The activated carbon was prepared from the Jing Bo shot coke using KOH as the activation agent by microwave heating. The effect of microwave radiation time, the microwave power and the ratio of activation to shot coke on the properties of the activated carbon were investigated in detail. The result showed that the optimized condition of preparation of activated carbon is as followed: the ratio of activation agent to shot coke is 3:1, the microwave power 900 W and the microwave radiation time is 40 min. In this condition, the BET surface area of the activated carbon is 2668 m²/g; the iodine adsorption value 2281 mg/g and the benzene adsorption value 1368 mg/g.
