Abstract :
Ba-SAPO-34 zeolite membrane was formed by membrane synthesis process using microwave (MW) heating and followed by membrane ion-exchange process with Ba^2+ cation. The Ba-SAPO-34 zeolite membrane was tested for the separation of CO2 from the CO2/CH4 binary gas mixture. The effects of separation temperature, pressure difference across the membrane and CO2 concentration in the feed on the separation performance of the Ba-SAPO-34 membrane were studied. By feeding CO2/CH4 binary mixture with 5–50 % CO2 to the Ba-SAPO-34 at 303 K and 100 kPa pressure difference, high CO2/CH4 separation selectivities in the range of 103–276 were obtained.
