Separation of hydrogen and carbon dioxide by inorganic membranes 

AI2O3 (10-20) 20 5.0 2.5x105 Toyo Soda [1985] anodic alumina 

A porous Vycor glass membrane and a porous gamma-alumina membrane, both having about the same pore diameter of 4 nm, were used to study the separation of hydrogen from other components in the gasification mixture [McMahon et al., 1990]. At a temperature up to a maximum hydrogen concentration of about 40% in the
