In this work, we prepared and characterized pellet-shaped ACs using the coconut shell with K₂CO₃ and coal tar pitch as the binder to comparison with other granule-shaped ACs. Also effects of activation temperature and time on the process yields and qualities of the product were investigated at the activation temperatures of 750, 800, 850℃ respectively. In order to investigate the physical properties, we obtained adsorption isotherms, methylene blue adsorption number, iodine value, specific surface area(S_(BET)) and pore analysis. The adsorption isotherms of liquid nitrogen vs. relative pressure (P/Po) on the pellet typed ACs at temperature (77K) show the same trend of Type I ; Langmuir adsorption isotherm. The iodine value was 998㎎/g, methylene blue adsorption number was 199㎎/g, average pore size was below 20Å, and specific surface area(S_(BET)) was 1010㎡/g with the total yield about 29wt.% on pellet-shaped ACs prepared at the activation temperature of 850 and activation time 90min. In this paper it was described the data of this experimental and analysis.
