| Description | Journal: Iop Conference Series: Materials Science and Engineering In this study, different parameters for the preparation of activated carbon were investigated for their yield and $CO_{2}$ capture capabilities. The activated carbon was prepared from Oil Palm Empty Fruit Bunch (OPEFB) via a 2-step physical activation process. The OPEFB was pyrolyzed under inert conditions at 500 °C and activated via $CO_{2}$. A 2-factorial design was employed and the effects of activation temperature, activation dwell time and gas flow rate on yield and $CO_{2}$ capture capabilities were compared and studied. The yield obtained ranged from between 20 – 26, whereby the temperature was determined to be the most significant factor in influencing $CO_{2}$ uptake. The $CO_{2}$ capture capacity was determined using Temperature Programmed Desorption (TPD) technique. The $CO_{2}$ uptake of EFB activated carbon achieved was between 1.85 – 2.09 mmol/g. TPD analysis has shown that the surface of AC were of basic nature. AC was found to be able to withhold the $CO_{2}$ up to 663°C before maximum desorption occurs. The surface area and pore size of OPEFB obtained from BET analysis is 2.17 $m^{2}$ $g^{-1}$ and 0.01 $cm^{3}$ $g^{-1}$. After activation, both surface area and pore size increased with a maximum observed surface area and pore size of 548.07 $m^{2}$ $g^{-1}$ and 0.26 $cm^{3}$ $g^{-1}$. Surface morphology, functional groups, pore size and surface area were analyzed using SEM, FT-IR, TPD and BET. |
