Preparation and Characterization of Activated Carbon Made from Oil Palm Empty Fruit Bunch

This paper explains preparation of activated carbon from empty fruit bunch (EFB) using steam activation under optimum conditions; activation temperature of 765°C and activation time of 77min and analyzes their physical and chemical properties using proximate and ultimate analysis, fourier transform infrared (FT-IR) analysis, x-ray diffraction (XRD) analysis, nitrogen adsorption-desorption analysis and scanning electron microscopy (SEM) analysis. Results show activated carbon EFB consists of 68.32 wt% carbon, 3.12 wt% hydrogen, 2.12 wt% nitrogen and 26.44 wt% oxygen content. FT-IR spectroscopy result indicate that raw EFB was successfully converted to carbon after activation process and was proven by spectra of commercial activated carbon. The XRD study confirms the presence of some crystalline (graphite) phase around peaks 26o and 43o. Characterization by using BET and SEM analysis showed that activated carbon produced from EFB has good properties with high surface area (720.0 m2/g) and well developed pores.
