Abstract:
Adsorption of CO2 on activated carbon derived from longan seed was investigated in this work to see how the porosity effects on adsorption isotherm and kinetics. Microporous activated carbon was produced by a two-step activation method. To enlarge the size of micropores, the activation and oxidation methods were carried on to prepared the mesoporous activated carbon. The prepared activated carbons then were characterized by nitrogen adsorption. The equilibrium and kinetics data for CO2 adsorption were taken at low pressures to atmospheric pressure at temperature of 273.15K using the micromeritics ASAP 2020 plus. The pore size distribution obtained from CO2 adsorption showed pore widths lower than 1 nm while that obtained from N2 isotherm cannot observed. For CO2 adsorption, the adsorption capacity compared between microporous- and mesoporous- activated carbon, it was found that the isotherm of microporous- activated carbon is greater than that of mesoporous carbon. This is due to the stronger interaction between fluid and pore walls. For the kinetic study of CO2 adsorption in activated carbon, pseudo- first order model show clearly different between microporous and mesoporous activated carbon more than pseudo-second order model. When adsorption time increased (adsorption capacity at equilibrium increased), the rate constant increased at maximum and then dropped down, it might be because of a pore blocking phenomenon
