Thin-film composite (TFC) membranes with superior separation properties for H2/CO2, CO2/N2, and CO2/CH4 are of great interest CO2 capture. As the selective layer becomes thinner (∼100 nm or less) to enhance gas permeance, it can be surface-engineered significantly improve properties. This paper aims critically review scalable nanotechnologies adopted modify membrane surfaces capture performance, including atomic deposition, chemical vapor plasma treatment, direct fluorination, ion/electron beam ozone surface-initiated polymerization. We first describe mechanisms these achieve desired surface chemistries nanostructures. Second, examples surface-modified enhanced performance highlighted, they compared state-of-the-art showcase their potential separations. Finally, we summarize pros cons technologies transform technology practical applications.

Carbon Capture Science & Technology, Год журнала: 2023, Номер 10, С. 100160 - 100160

Опубликована: Ноя. 10, 2023

Membrane technology scientists proposed hollow fiber membrane contactors (HFMCs) as an alternative to conventional CO2 absorption-desorption columns due their promising advantages and outstanding performance for capture. However, the HFMC systems suffer from wetting phenomena; hence, studies focus on optimizing material, liquid absorber, operating conditions. As have addressed phenomenon with these solutions, new issues emerged. In addition, feedback loop between lab industrial scale has been ignored. this review, characteristics of different based types, including porous, dense, composite (e.g., thin-film mixed matrix) membranes, are compared clarify disadvantages. Also, scale-up economic conditions were discussed in terms HFMC's feasibility highlight importance industry loop. Furthermore, future direction is stated accelerate HFMCs' development provide a clear strategy achieving practical theatrical absorption through HFMCs.

The use of deep eutectic solvents (DESs) for the preparation polymer membranes environmental separation technologies is comprehensively reviewed. DESs have been divided into five categories based on hydrogen bond donor (HBD) and acceptor (HBA) that are involved in production DESs, a wide range DESs’ physicochemical characteristics, such as density, surface tension, viscosity, melting temperature, initially gathered. Furthermore, most popular techniques creating demonstrated discussed, with focus non-solvent induced phase (NIPS) method. Additionally, number studies reported which were employed pore formers, solvents, additives, or co-solvents, among other applications. addition to manufacturing process increased presence finger-like structures macrovoids cross-section and, numerous occasions, had substantial impact overall porosity size. Performance data also gathered made various technologies, ultrafiltration (UF) nanofiltration (NF). Lastly, provide options functionalization membranes, creation liquid membrane types, special supported (SLMs) decarbonization discussed terms permeability selectivity several gases, including CO2, N2, CH4.
