Mixed matrix membrane of alginate zeolit crosslinked by PVA for separation of CO2/CH4

Abstract

Mixed Matrix Membrane Alginate Zeolite Crosslinked by PVA for Separation CO2/CH4 was studied. Alginate/Zeolite/PVA mixed matrix membrane were prepared by solution casting. The research started by synthesis of Alginate/Zeolite/PVA membrane. The PVA 0.1% crosslinking alginate zeolite membrane (1:0.2) wa successfully synthesized. The membrane were characterized by Fourier Transform Infrared (FT-IR) and Barret Joyner Hallenda (BJH). The membrane permeability and selectivity of CO2 and CH4 were investigated. The effect of zeolite on the performance and the thickness of membranes of gas separation were analyzed. The result of permeability and selectivity show that membrane can flow CO2 and resist CH4. The effect of zeolite mass increasing on permeability of CO2. The thickness of membrane influenced the flux of CO2 gas. CO2 permeability increased simultaneously with a decrease of a membrane thickness. According BJH result, pore diameter of membrane is 3.54 A, while kinetic diameter of CO2 is 3.3 A and kinetic diameter of CH4 is 3,8 A. This was explained performance of membrane was molecular sieving.
