H2 permeability decreased with increasing the temperature before silica coating both in Vycor glass and alumina membrane.? However, H2 permeability increased with increasing the temperature, that was an indication of activated transport after silica coating both in Vycor glass and alumina membrane. Lower permeability values and higher selectivities were obtained in Vycor glass membrane than alumina membrane having higher permeability and lower selectivities.展开更多
