Membrane-based gas separations are energy efficient processes; however, major challenges remain to develop high-performance membranes enabling the replacement of conventional separation processes. Herein, a new fluorinated MOF-based mixed-matrix membrane is reported, which formed by incorporating MOF crystals into selected polymers via facile approach. By finely controlling molecular transport in channels through apertures tuned metal pillars and at MOF-polymer interfaces, resulting exhibit...
Mixed matrix membranes (MMMs) could combine the advantages of both polymeric and porous fillers, making them an effective alternative to conventional polymer membranes. However, interfacial incompatibility issues, such as presence voids, hardening chains, blockage micropores by polymers between common MMMs fillers matrix, currently limit gas separation performance MMMs. Ternary phase (consisting a filler, additive, matrix) made adding third compound, usually functionalized additives, can...
The procedures for the synthesis of polypyrrole (PPy) doped with anionic spherical polyelectrolyte brushes (ASPB) (PPy/ASPB nanocomposite) by means in situ chemical oxidative polymerization were presented.Fourier transform infrared spectroscopy (FTIR) and Raman spectroscopic analysis suggested bonding structure PPy/ASPB nanocomposite.Scanning electron microscopy (SEM) was used to confirm morphologies samples.The crystallographic structure, nature thermal stability conducting polymers...
Membrane-based separation of combined acid gases carbon dioxide and hydrogen sulfide from natural gas streams has attracted increasing academic commercial interest. These feeds are referred to as "sour," herein, we report an ultra H2S-selective exceptionally permeable glassy amidoxime-functionalized polymer intrinsic microporosity for membrane-based separation. A ternary feed mixture (with 20% H2S:20% CO2:60% CH4) was used demonstrate that a membrane provides unprecedented performance under...
Membrane-based separations offer great potential for more sustainable and economical natural gas upgrading. Systematic studies of CO
Sorption and permeation properties of a hydroxyl-functionalized polymer with intrinsic microporosity are reported for aggressive sour natural gas separations.
The effects of pyrolysis protocols on the pore structure and gas separation performance PI- PIM-derived CMS membranes were systematically summarized discussed, research progress in CO 2 olefin/paraffin was reviewed.
Most examples of mixed-matrix membranes (MMMs) involve one type polymer and inorganic filler particle. Here, both blending MMM approaches are combined to form exceptional three-component for CO2/N2 separation. Nano-sized amino-functionalized UiO-66 is added a blend PIM-1 an ether side chain functionalized polyphosphazene (MEEP80) create series MMMs. Incorporation UiO-66-NH2 particles boosts the CO2 permeability PIM-1/MEEP80 (75:25) from 3140 up nearly 6000 Barrer, while maintaining its...
Membrane separation is a promising alternative for gas purification. Facilitated transport (FT) membranes, with reversible reactions to promote CO2 transport, can simultaneously obtain high permeability and selectivity of over other gases, such as CH4, making FT membranes particularly interesting CO2/CH4 separation. An overview the state-of-the-art used desired R&D industrial membrane applications. This paper has reviewed development progress advances in various separation, including mobile...
