“…The lower flow rate ratio caused much non-solvent liquid to flow into the lumen side of the fiber, promoting the non-solvent diffusion rate and inducing prompt phase inversion. As per the work of Zhu et al [17], instantaneous phase inversion facilitates the formation of more and larger finger-like voids, resulting in an inferior gas separation performance, which was consistent with the trend observed in this section.…”

“…All inter-surface micrographs of the developed MMHFMs prepared with different flow rate ratios are depicted in Figure 3a1-c1, showing the rough morphology; there were no manifest cracks or defects in the membrane surface. This suggests the fillers were perfectly wrapped in the polymer chains, and there were favorable interactions between the polymeric matrix and fillers [17], as evidenced in Figure 1. The typical sandwich-like structure is also displayed in Figure 3a2-c2.…”

This work reported on the fabrication and investigation of a mixed matrix hollow fiber membrane (MMHFM) by incorporating commercially available alumina particles into a polyetherimide (PEI) polymer matrix. These MMHFMs were prepared by the dry-wet spinning technique. Accordingly, optimizing the spinning parameters, including the air gap distance and flow rate ratio, is key to determining the gas separation performance. However, there are few studies regarding the effect of the filler dimensions. Consequently, three sizes of alumina particles, 20 nm, 30 nm, and 1000 nm, were respectively added into the PEI phase to examine the influence of filler size on gas permeation property. Moreover, the permeation properties of lower hydrocarbons (i.e., ethane and propane) were also measured to evaluate potential for emerging applications. The results indicated the as-synthesized membrane exhibited a remarkable hydrogen permeance of 1065.24 GPU, and relatively high separation factors of 4.53, 5.77, and 5.39 for H2/CO2, H2/C2H6, and H2/C3H8, respectively. This resulted from good compatibility between the larger fillers and the PEI polymer, as well as a reduction in the finger-like voids. Overall, the MMHFM in this work was deemed to be a promising candidate to separate hydrogen from gas streams, based on the comparison of the separation performance against other reported studies.

“…The CO 2 permeability increment can be ascribed to the porous structure of NiX zeolite that provides secondary channels for gas transport. Therefore, gas molecules tend to pass through NiX zeolite pores instead of the Ultem matrix 85 . Besides, some functional groups such as ether, carbonyl, and hydroxyl are CO 2 ‐philic.…”

CO₂ separation of a novel Ultem‐based mixed matrix membrane incorporated with Ni²⁺‐exchanged zeolite X

et al. 2021

In this study, polyetherimide (Ultem) was chosen as a polymeric matrix, and micron‐sized Ni2+‐exchanged nano‐porous NaX zeolite was selected as an inorganic filler to fabricate novel mixed matrix membranes (MMMs) for CO2 separation. Fabricated membranes were evaluated by Differential scanning calorimeter, Fourier transform infrared spectroscopy, X‐ray diffraction, scanning electron microscopy, and energy dispersive X‐ray. The influences of filler loading (0–5 wt.%) and feed pressure (2–10 bar) on gas separation properties were surveyed. CO2/N2 ideal selectivity of 3 wt.% NiX loaded MMM (optimum MMM) was increased to 34 (about 36%) compared to 25 for the pristine membrane. Furthermore, CO2 permeability was improved by about 45%, from 1.3 Barrer for the pure membrane to 1.88 Barrer for MMM containing 3 wt.% functionalized filler. These improvements originate from a combination of the inherent surface diffusion mechanism of zeolite X and reversible reaction between free orbitals of transition metal ions (Ni2+) and electron pairs of CO2 molecules. © 2021 Society of Chemical Industry and John Wiley & Sons, Ltd.

“…The aminosilane acts as an adhesion promoter or bridging agent that improves the interfacial bonding between the bulk polymer and the inorganic surface, reducing the repulsive force at the polymer/filler interface when removing the solvent during MMM fabrication 35 . The commonly used aminosilanes in fabrication of modified MMM are 3‐ aminopropyldimethylethoxysilane (APDMES), 3‐aminopropylmethyldiethoxysilane29 (APMDES), 3‐aminopropyltriethoxysilane (APTES), and 3‐aminopropyltrimethoxysilane (APTMS) 112‐116 . Nik et al 117 found that the number of alkoxy groups in aminosilane and solvent polarity can affect the amount of amino grafted on zeolite surface.…”

Recent progress in the development of ionic liquid‐based mixed matrix membrane for CO ₂ separation: A review

et al. 2021

View full text Add to dashboard Cite

Summary Carbon capture and storage (CCS) technologies have gained global attention due to the environmental impact caused by CO2. Ionic liquid, also known as a designer solvent, has good potential for CO2 capture application due to its good CO2 affinity, negligible vapor pressure and high thermal stability. The combination of ionic liquid and membrane technology has been introduced for the more effective use of ionic liquid. This review offers a comprehensive overview of mixed matrix membrane (MMM) and the application of ionic liquid in the membrane for CO2 separation, focusing on recent advances in ionic liquid‐based MMM. Descriptions of various MMM modification strategies using ionic liquid and the influence of challenging operating conditions on the CO2 separation performance of ionic liquid‐based MMM are discussed.
