Mixed matrix membranes of Pebax-1657 loaded with 4A zeolite for gaseous separations

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.…”

Mixed Matrix Membranes with Excellent CO2 Capture Induced by Nano‐Carbon Hybrids

“…For comparison purposes, the gas separation performance of the Pebax‐1657 based membranes reported by other researchers is listed in Table S1 . It was observed that the CO 2 /gas selectivity and CO 2 permeability of Pebax‐MWCNT@GONRs‐1 in this work were higher than those of most Pebax‐1657 based membranes reported.…”

“…Furthermore, the permselectivities of the as‐prepared membranes were also compared with Robeson's upper bound limit as illustrated in Figure a and b . As can be seen in this Figure, by incorporating MWCNT@GONRs in Pebax‐1657 matrix, the MMMs separation performance presented great improvements and was closed to Robeson's upper bound.…”

“…For comparison purposes, the gas separation performance of the Pebax-1657 based membranes reported by other researchers is listed in Ta ble S1. [29,[32][33][34][35][36][37][38] It waso bserved that the CO 2 /gas selectivity and CO 2 permeability of Pebax-MWCNT@GONRs-1 in this work were higher than those of mostP ebax-1657 based membranes reported. For instance, the Pebax-SWCNT-5 membranesh ad the CO 2 permeability of 102.0 Barrer and selectivity of 73 for CO 2 /N 2 .…”

“…Furthermore,t he permselectivities of the as-prepared membranesw ere also compared with Robeson's upper bound limit as illustrated in Figure 10 aa nd b. [29,[32][33][34][35][36][37][38] As can be seen in this Figure, by incorporating MWCNT@GONRs in Pebax-1657 matrix, the MMMs separation performance presented great improvements and was closed to Robeson's upper bound. For CO 2 /N 2 separation, Pebax-MWCNT@GONRs-1 at the operating pressureo f4bar and 35 8Cf ar surpassed the 2008 Robeson upper boundl imit and had fairly good gas separation performance in comparison to the similarP ebax-1657 based membranes.…”
