| Description | Journal: Iop Conference Series: Materials Science and Engineering It is well-known that activated carbon is considered to be the general adsorbent due to the large range of applications. Numerous works are being continuously published concerning its use as adsorbent for: treatment of potable water; purification of air; retention of toxins by respirators; removal of organic and inorganic pollutants from flue gases and industrial waste gases and water; recuperation of solvents and hydrocarbons volatilized from petroleum derivatives; catalysis; separation of gas mixtures (molecularsieve activated carbons); storage of natural gas and hydrogen; energy storage in supercapacitors; recovery of gold, silver and othernoble metals; etc. This work presents producing activated carbons from palm empty fruit bunch using both physical activation with $CO_{2}$ and chemical activation with KOH. The resultant activated carbons were characterized by measuring their porosities and pore size distributions. A comparison of the textural characteristics and surface chemistry of the activated carbon from palm empty fruit bunch by the $CO_{2}$ and the KOH activation leads to the following findings: An activated carbon by the $CO_{2}$ activation under the optimum conditions has a BET surface area of 717 $m^{2}$/g, while that by the KOH activation has a BET surface area of 613 $m^{2}$/g. The $CO_{2}$ activation generated a highly microporous carbon (92%) with a Type-I isotherm, while the KOH activation generated a mesoporous one (70%) with a type-IV isotherm, the pore volumes are 0.2135 and 0.7426 $cm^{3}.g^{-1}$ respectively. The average pore size of the activated carbons is 2.72 and 2.56 nm for KOH activation and $CO_{2}$ activation, respectively. The FT-IR spectra indicated significant variation in the surface functional groups are quite different for the KOH activated and $CO_{2}$ activated carbons. |
