“…The permeation test for pure CH 4 was carried out before using pure CO 2 permeation test. It is worth noting that repeating the pure CH 4 permeation test immediately after using CO 2 produced the same results indicating that there were no CO 2 plasticization or dilation effects [24] on these membranes.…”

Synthesis of polyetherimide-bismaleimide (PEI-BMI) semi-interpenetrating polymer networks (semi-IPNs) combined with solvent phase inversion was used to prepare asymmetric flat membranes, which were coated with silicon rubber. These membranes were evaluated for production of O 2 -enriched air and separation of CO 2 from its mixture with CH 4 as well as with N 2 . Using different preparation schemes membranes with varying skin and supported layer characteristics were prepared. These different morphologies of membranes were responsible for a trade-off performance between gas permeance and permselectivity. These new composite, PEI-BMI semi-IPN membranes showed suitable performance for production of O 2 -enriched air and separation of CO 2 from natural gas or flue gas relevant to greenhouse gas emission control. Membrane performance was explained in terms of the intrinsic gas transport properties of the coated silicon layer and membrane glassy material, which determine the limitations of permeance-permselectivity trade-off. It was also found that the permselectivity for CO 2 over CH 4 or N 2 increases with increasing CO 2 feed concentration. This might be exploited to arrange for more cost-efficient multistage gas separation systems. Crown

“…This sharp decrease was influenced from plasticization effect by CO 2 . From literature (Visser et al, 2005) when a membrane is plasticized by one component from a mixture, the permeability or flux of the other one is increased as well. It could be understand that the selectivity also decreased as the concentration of CO 2 reduced, Fig.…”

Carbon hollow fiber membranes have been prepared by pyrolysis of a P84/S-PEEK blend. Proximate analysis of the precursor was performed using thermogravimetry (TGA), and a carbon yield of approximately 40% can be obtained. This study aimed at understanding the influence of pyrolysis parameters-end temperature, quenching effect, and soaking time-on the membrane properties. Permeation experiments were performed with N 2 , He, and CO 2 . Scanning electron microscopy (SEM) has been done for all carbon hollow fibers. The highest permeances were obtained for the membrane submitted to an end temperature of 750• C and the highest ideal selectivities for an end temperature of 700 • C. In both cases, the membranes were quenched to room temperature.
