High-silica CHA (SSZ-13) zeolite membranes exhibit great potential for CO2separation. However, the practical application is significantly hindered by the high investment cost. Here, we synthesized SSZ-13 zeolite membranes on four-channel hollow fibers with pore size of 150 nm, 370 nm and 600 nm, respectively. The CO2/CH4selectivity of 127 ± 11 as well as CO2permeance of (3.1 ± 0.6) × 10-7mol m−2s−1Pa−1was achieved on the membranes synthesized on the hollow fibers with 150 nm pore size at 433 K for 96 h. The single gas permeation was quantitively assigned to evaluate surface diffusion, Knudsen diffusion and viscous flow through the as-synthesized membranes. The permeation of small molecules (e.g., CO2and N2) is mainly contributed by the zeolitic pores, however, the permeation of relatively big molecule (e.g., CH4) is more sensitive to the non-zeolitic pores. For the membranes withαCO2/CH4of 130 and 48, the non-zeolitic pores contributed 24.7% and 69% of CH4permeance, respectively.
