Gas separation technology by adsorption processes has been widely applied in many related industries, such as petrochemicals, environmental technology, oil and gas industries. One of the typical applications of Carbon Molecular Sieve is as the separation barrier for separation of light gases. This application was known since 1950s. Recently as for gas separation, development carbon molecular sieve (CMS) has gained much attention by the engineers worldwide. One of the typical examples of gas separation is air separation. For the separation of air for nitrogen, N2 and oxygen, 0 2• it can be carried out by Pressure-Swing-Adsorption (PSA) over carbon molecular sieve. CMS adsorbent are widely used in gas separation process because it has effective micro pore diameter ranging from 0.14nm to 0.9nm which is comparable to the molecular diameter of adsorbates to be separated. In this work, carbon molecular sieve was synthesized from commercial activated carbon. After synthesized process completed, these material were subjected to carbonization at 600°C under an inert atmosphere. These materials then were analysed by Scanning Electron Microscopy (SEM) for structural analysis. The molecular sieve surface area and porosity will be estimated using BET method.
