Abstract

With the introduction of fuel cells for vehicular propulsion and power generation, hydrogen demand may increase significantly. The separation of hydrogen from its source gas mixtures is often the first step for the hydrogen applications. Thus, the synthesis and hydrogen separation properties of MFI and NaA zeolite membrane were studied. The NaA zeolite membrane showed a H₂ permeance of 2.86 × 10^-7 mole/sq m-sec-Pa. The H₂/N₂ and H₂/n-C₄H₁₀ permselectivity was 23.8 and 106, respectively, at 298 K. With the increase in permeation temperature, gas permeance increased. The H₂/N₂ and H₂n-C₄H₁₀ permselectivity gradually decreased with the increase in permeation temperature. Both MFI and NaA zeolite membrane showed a high H₂/n-C₄H₁₀ permselectivity.
