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.
