Gas permeation of hydrogen (H2) and nitrogen (N2) were obtained from 30 and 6000 nm pore diameter tubular commercial alumina ceramic membranes at 0.05 to 1.00 bar and 298 K. Flow rates of up to 3.279 and 2.296 l/min were obtained for H2 and N2 respectively. The ratio of H2/N2 flow rates were used to calculate H2/N2 selectivity. The experimental H2/N2 selectivities obtained were 1.85 and 1.43 for the 30 and 6000 nm respectively.
