文摘

Olefin/nitrogen separation was studied with ultra-thin MFI membrane. In separation of olefin/nitrogen, the membranes were hydrocarbons selective. Very high selectivity was obtained for separation of propylene/nitrogen mixture. Very high permeance was obtained for separation of propylene/nitrogen and ethylene/nitrogen mixtures. The separation with high permeance was affected by concentration polarization.
