STUDY ON OPTIMUM CONDITIONS OF PREPARATION OF ACTIVE CARBON FROM PETROLEUM COKE

Series of active carbons were prepared from petroleum coke by simple activation and co - activation. The effects of grain size of raw coke, activation temperature and time on adsorption properties were studied and also the effect of the concentration of activation agents. Results show that the adsorption capacities of coactivation active carbons are much higher than those of simple activation active carbons. The superior activated carbon was available under the optimum condition of activation(mkoH/mcarbon: 2/1, temperature: 850℃, velocity of steam: 13. 6ml/min).
