新しいポリイミド膜の気体透過

概要

論文の詳細を見る
The permeability and apparent diffusivity calculated from time lag characterizing transport in a new type polyimide (PI) membrane have been measured for hydrogen, hellium, argon, oxygen, nitrogen, carbon monoxide, carbon dioxide, methane, ethane and propane. The apparent activation energies for permeation and diffusion have been also determined. The diffusivities were correlated with mean diameter of permeate gas molecules. The possibility of PI for gas separation membrane was discussed shortly.
