“…So, CO 2 permeability is not much sensitive to temperature. Moreover, CO 2 solubility decreases more significant with temperature, but the solubility of N 2 increases . In addition, the obvious increase of N 2 permeability with elevating temperature is also due to its faster increase of diffusivity than CO 2 .…”

CO 2 -selective Pebax/NaY mixed matrix membranes (MMMs) were prepared by incorporating NaY zeolite into Pebax matrix. The morphology, chemical groups, thermal stability, and microstructure of the MMMs were investigated by scanning electron microscope, Fourier transform infrared spectroscopy, thermogravimetric analysis, and X-ray diffraction, respectively. The effects of zeolite loading amount, permeation temperature and pressure on the CO 2 /N 2 separation performance of the resultant membranes were studied. The as-prepared MMMs are much superior to the pristine Pebax membranes in terms of permeability and selectivity. The CO 2 permeability and CO 2 /N 2 selectivity can respectively reach to 131.8 Barrer and 130.8 for MMMs made by the starting materials containing 40 wt % NaY.

Membranes for CO₂ /CH₄ and CO₂/N₂ Gas Separation

Membrane technology has emerged as a leading tool worldwide for effective CO 2 separation because of its well-known advantages, including high surface area, compact design, ease of maintenance, environmentally friendly nature, and costeffectiveness. Polymeric and inorganic membranes are generally utilized for the separation of gas mixtures. The mixed-matrix membrane (MMM) utilizes the advantages of both polymeric and inorganic membranes to surpass the trade-off limits. The high permeability and selectivity of MMMs by incorporating different types of fillers exhibit the best performance for CO 2 separation from natural gas and other flue gases. The recent progress made in the field of MMMs having different types of fillers is emphasized. Specifically, CO 2 /CH 4 and CO 2 /N 2 separation from various types of MMMs are comprehensively reviewed that are closely relevant to natural gas purification and compositional flue gas treatment

“…Simultaneous topographical and phase detection was applied on membrane cross‐sections through tapping‐mode AFM. A recent study on gas separation membranes also used this principle for more detailed characterization of this type of block copolymers . More generally, the phase change is sensitive to surface properties of polymeric materials, such as viscoelasticity, stiffness, and composition .…”

This work explores the possibilities to blend block copolymers, i.e., Pebax MH 1657, with a variety of cheap poly(propylene oxide)‐rich molecules which could potentially play a double role in the resulting membranes as dispersing/stabilizing agents in multi‐component casting solutions and as a gas transport medium in the final membrane. These membranes were prepared by solution casting and were characterized by differential scanning calorimetry, scanning electron microscopy, atomic force microscopy, X‐ray diffraction, density measurements, and Fourier transform infrared‐attenuated total reflection, while additive incorporation was also studied with theoretical calculations. Gas permeation measurements showed that this approach resulted in increased permeabilities at the expense of mixed‐gas selectivity. An interpretation of the blend structure was finally made using gas transport models. The compatibility of these additives with the synthesis of selective gas separation membranes may enable a potential double role in membrane synthesis, i.e., as stabilizing agents in membrane synthesis and as a gas transport medium in the final membrane. © 2018 Wiley Periodicals, Inc.
