Facilitated transport mixed matrix membranes incorporated with amine functionalized MCM-41 for enhanced gas separation properties

Role of Facilitated Transport Membranes and Composite Membranes for Efficient CO2 Capture – A Review

“…The increasing trend with the RH indicates that the solution-diffusion mechanism has a small contribution toward CO 2 transport through the membrane. Similar trends were observed by other workers which indicated that faster rate of diffusion was due to the formation of HCO3 -through this water-swollen FSC membrane, which eventually exhibits high CO 2 permeance and consequently high selectivity [2,66,70]. Some of the water in the flue gas stream will inevitably permeate with the CO 2 in these facilitated transport membranes.…”

Synergistic effect of combining carbon nanotubes and graphene oxide in mixed matrix membranes for efficient CO2 separation

“…The gas permeabilities of membranes were measured by a permeation measurement equipment described in the previous literature [38,39]. The experiments were carried out using a conventional constant pressure/variable volume method [40].…”

Mixed matrix membranes comprising of matrimid and mesoporous COK-12: Preparation and gas separation properties

“…Due to their inherent limitations, achieving the desired performance has proved to be a rather difficult task. Mixed matrix membranes (MMM), comprising of inorganic fillers such as zeolite [2,[12][13][14], mesoporous silica [15][16][17][18], carbon molecular sieves [19][20][21], carbon nanotubes [22][23][24] or metal organic frameworks (MOFs) [25][26][27][28], have emerged as promising candidates to surpass Robeson's upper bound. These membranes combine the easy processability and low cost of the polymeric materials with the high stability and permeability and/or selectivity of the inorganic fillers.…”

“…Among different materials used as fillers, ordered mesoporous molecular sieves have received widespread interest [15][16][17][18]29]. Due to their high surface areas, adjustable and bigger pore size leading to increased gas diffusion and possibility of functionalization, they have proven to be promising fillers in membranes.…”

“…While substantial increase in gas permeability was reported, either selectivity decreased or increases observed were insignificant. Recently, several efforts were made to enhance the filler/penetrant gas interaction by functionalization of mesoporous materials [15,16,18,30,34]. In one of our previous studies, MCM-41 was functionalized with -SO 3 H groups to increase CO 2 solubility [16].…”
