Title: E211 Effect of H_2 Mole Fraction of H_2/N_2 Mixture on the Hydrogen Permeation Rate for Pd/Ag Membrane
Abstract: Effect of H_2 mole fraction of H_2/N_2 mjxture on the hydrogen permeation mole flux through Pd/Ag membrane with 25μm thickness and 0.02m diameter, was discussed theoretically. The effect was investigated at various feed mole flux (0.05-0.95mol/s.m^2), for total pressure at upstream side of 0.25MPa and membrane temperature of 623K. The results show that the hydrogen permeation mole flux increases with an increase in the feed mole flux, and becomes closer to the permeation mole flux estimated by the ordinary Sieverts' equation. In addition, it is shown that the trend of the increase follows the first order lag system, regardless of the H_2 mole fractions in the feed flow.
