Kinetics Of

Activated carbon was prepared from palm shell by pyrolysis followed by K2CO3 assisted microwave heating. Effects of temperature on adsorption capability and kinetics of the sorbent towards CO2 adsorption was also studied. The results indicated that, the amount CO2 adsorbed decrease as the adsorption temperature increases. The kinetic data were obtained using a static volumetric method at 303.15, 343.15, 378.15, and 443.15 K and at pressures up to 4 bar. The kinetics of CO2 adsorption on the activated carbons was examined using the pseudofirst-order equation and pseudosecond-order equations. Weber and Morris intraparticle diffusion model was applied to examine the mechanism of the adsorption system. Lowest CO2 uptake recorded was 0.3 mmol/g at 443.15 K and 0.5 bar while the highest was 7.45mmol/g obtained at 303.15 K and 4 bar. The kinetics followed pseudosecond-order model. Pore diffusion is not the sole rate diffusion mechanism.
