Preparing Carbon Molecular Sieve Membrane (CMSM) for Olefin/Paraffin Separation. Carbon molecular sieve membrane (CMSM) presents superior selectivity and stability for many gas separation processes. This technology is energy saving, environmental friendly and with minimal operating cost. The project will develop CMSMs for the separation of olefin/paraffin, particularly, the propane/propylene mixture which is currently separated by the energy intensive cryogenic distillation in industry.

Carbon molecular sieve membrane (CMSM) presents superior selectivity and stability for many gas separation processes. This technology is energy saving, environmental friendly and with minimal operating cost. The project will develop CMSMs for the separation of olefin/paraffin, particularly, the propane/propylene mixture which is currently separated by the energy intensive cryogenic distillation in industry. The project involves both experimental works and theoretical studies and will provide: (1) techniques for preparing CMSMs for olefin/paraffin separation; (2) methods characterizing the micro-structure of CMSMs; (3) mathematical models predicting multicomponent gas permeation/separation properties on CMSMs; (4) effect of impurities on the separation processes.
