Membrane separation technology is gaining importance nowadays in reducing the emission of carbon dioxide (CO2) as greenhouse gas due to the global climate change. Gas permeation studies play significant role in reflecting the potential of the membranes in separating the gas mixtures. In this study, Ba-SAPO-34 zeolite membrane was formed by membrane synthesis process using microwave (MW) heating and followed by membrane ion-exchange process with Ba2+ cation. The Ba-SAPO-34 zeolite membrane was investigated for its performance in the CO2 and N2 gases permeation studies. The effects of permeation temperature (30 - 180 °C) and pressure difference (100 - 500 kPa) across the membrane on the gas permeation performance of the Ba-SAPO-34 membrane were studied. CO2 single permeance of ~9.4-19.5 � 10-8 mol/m2.s.Pa and N2 single permeance of ~0.635-0.694 � 10-8 mol/m2.s.Pa were obtained for gases permeation through Ba-SAPO-34 membrane performed under the range of permeation temperature and pressure difference across the membrane studied. Maximum CO2/N2 ideal selectivity of 29.6 was obtained for gases permeation through Ba-SAPO-34 membrane at 30 °C and 100 kPa pressure difference. © 2016, Malaysian Society of Analytical Sciences.
