permeance for the bare

Figure 8: N₂ and CO₂ permeance for the bare support (circle), the zirconia membrane ZrO₂/1/ with one coating (square), and the zirconia membrane ZrO₂/2/ with 2 coatings (triangle) as a function of the applied gas pressure; (b) N₂ and CO₂ permeance and selectivity of the double coated zirconia CFPmodified membrane (ZrO₂/2/-CFP).
