Abstract

This paper examines gas permeation properties (feed pressure, temperature, molecular weight) using -alumina mesoporous ceramic membrane with 15 nm average pore size. Scanning electron microscopy (SEM) of the membrane’s cross-sectional area was analyzed in this experiment. Single gas permeation of hydrogen, helium, methane, nitrogen, argon and carbon dioxide was determined at permeation temperature range of 25 0C - 450 0C and feed pressure range 0.05 to 10 bar. It was shown that the transport mechanism under these conditions is governed by a combination of viscous and Knudsen diffusion.
