Abstract:Activated carbon (AC) was produced from palm empty fruit bunch through pyrolysis, chemical impregnation and activation. Empty fruit bunch (EFB) was dried and sieved to 3 to 10 mm. The chars formed were modified with phosphoric acid (H3PO4) and then activated in CO2 stream. The AC produced was characterized by Scanning Electron Microscope (SEM), Brunauer Emmett and Teller (BET) surface area, Fourier Transform Infrared Spectroscopy (FTIR). Natural gas (NG) adsorption on the AC was carried out by passing the NG from loading cell to adsorption cell containing the sorbent. Amount of gas adsorbed was obtained from mass balance carried out across the dual cells. The amount of NG adsorbed from the process is 15.926 mmol/g adsorbent. The results indicate that the EFB-AC is a good adsorbent which can used to adsorb NG efficiently.
