Abstract

This work presents the transport behaviour of carrier gases with inorganic ceramic membrane used for environmental gas separations at 289K and 0.01-1 bar. The gases tested include: Helium (He), Nitrogen (N2), Carbon dioxide (CO2) and Argon (AR). The Knudsen ideal selectivity ration of 0.95, 0.3 and 0.79 for Ar/CO2, He/CO2 and N2/CO2 gas respectively was slightly higher that the theoretical selectivity of the gases. The gas permeance was found to decrease with increase in gauge pressure indicating mass transfer limitation. However, at a relatively low pressure of 0.1 bar, Knudsen diffusion mechanism was dominant for He and N2 gases flow across the modified ceramic membrane in relation to the inverse proportionality of the square root of their molecular weights. Scanning electron microscopy (SEM) was used to determine the pore size distribution of the {esc}ga{esc}s-Al2O3 ceramic support.
