Abstract
The properties, the advantages and drawbacks of hollow fiber carbon molecular sieving membranes as gas separators are discussed. Some mechanistic aspects are surveyed and permeability of methane-hydrogen mixture through the carbon membrane was studied. The presence of methane which is adsorbable and a poor permeant, does not impair the permeability of hydrogen even at temperatures as low as -80°C. This suggests that, because of the large difference in size of the two molecules, they occupy different positions in the membrane material prior to the jump through a critical constriction.Keywords
