Development of adsorption selective carbon membrane using cellulose acetate for separation of O2/N2 and C1-C4 hydrocarbons/N2

The objective of this study is to develop a new kind of carbon membrane which could separate gas based on the adsorption concept. This study was subjected to encounter challenges imposed by general trade off between permeability and selectivity of membrane. Membrane was prepared from a thermosetting...
