1 Characteristics of the Adsorbent

The surface morphological changes of powder and carbon samples were investigated using a Scanning Electron Microscope (SEM). The figure 2 and 3 shows the Scanning Electron Microscopy of orange peel powder and carbon made from powder. Carbon made from powder showed more porous structure than orange peel powder. Orange peel powder showed vertical vein type structure and carbon made from powder showed more porous structure with holes which gave maximum adsorption capacity than the orange peel powder.

Table-1 and 2 represents the elemental analysis of Orange peel powder and carbon made from Orange peel powder respectively. Besides that this component is widely used to be manufactured as an adsorbent to adsorb (CO2) gas. Orange peel contain Potassium Oxide (K2O) with 1.72%, Calcium Oxide (CaO) with 1.31% and others components in the minority. Therefore, with the great amount of carbon component, carbon produced from orange peel and also orange peel itself is one of the potential adsorbent to adsorb CO2 from gas mixture.
