ABSTRACT

The main objective in this work is study the influence of activation times in the

preparation of activated carbon by the method of potassium carbonate (K2CO3)-

chemical activation. The characteristics and pore development of the prepared activated

carbon were investigated. The experiments were carried out with activation time varied

from 0.5 to 4.0 h. The results show that in all cases, increasing the activation time the

yield decreases, while the adsorption of CO2 will increase, progressively. It was found

that the specific surface area of activated was at a maximum value (about 1170 m2/g) at

a activation time of 2.0 h with carbonization temperature of 8000C and at an

impregnation ratio of 1.0.
