1 Characteristics of the adsorbent The surface morphological changes of the powder and carbon samples were studied using a scanning electron microscope (SEM) . Figures 2 and 3 show scanning electron microscopy of orange peel powder and carbon made from powder. Carbon made from powder had a more porous structure than orange peel powder. The orange peel powder exhibited a vertical vein-like structure and the carbon made from powder exhibited a more porous structure with holes that gave maximum adsorption capacity than the orange peel powder. Figure 2 Scanning electron microscopy Figure 3 Scanning electron microscopy of orange peel powder of orange peel carbon Table -1 and 2 represent the elemental analysis of orange peel powder and carbon made from orange peel powder. Furthermore, this component is widely used to be manufactured as an adsorbent to adsorb gas (CO2). Orange peel contains potassium oxide (K2O) at 1.72%, calcium oxide (CaO) at 1.31% and other components in the minority. Therefore, with the large amount of carbon, the carbon produced from orange peel and also orange peel itself is one of the potential adsorbents to adsorb CO2 from the gas mixture.
