Mixed Matrix Membrane Alginate Zeolite Crosslinked by PVA for Separation CO 2 /CH 4 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 CO 2 and CH 4 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 CO 2 and resist CH 4 . The effect of zeolite mass increasing on permeability of CO 2 . The thickness of membrane influenced the flux of CO 2 gas. CO 2 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 CO 2 is 3.3 A and kinetic diameter of CH 4 is 3,8 A. This was explained performance of membrane was molecular sieving.
