“…Secondly, waste heat can be used to provide the energy that is needed for temperature swing. Therefore, the low temperature difference between the regeneration and adsorption steps of TSA (30-150 • C) and the possibility to use the available waste heat reduce the operating cost, thereby promoting the implementation of TSA [46]. Nowadays, TSA is mainly employed for post-combustion capture of CO 2 from flue gases [47].…”

Carbon dioxide (CO2), which results from fossil fuel combustion and industrial processes, accounts for a substantial part of the total anthropogenic greenhouse gases (GHGs). As a result, several carbon capture, utilization and storage (CCUS) technologies have been developed during the last decade. Chemical absorption, adsorption, cryogenic separation and membrane separation are the most widely used post-combustion CO2 capture technologies. This study reviews post-combustion CO2 capture technologies and the latest progress in membrane processes for CO2 separation. More specifically, the objective of the present work is to present the state of the art of membrane-based technologies for CO2 capture from flue gases and focuses mainly on recent advancements in commonly employed membrane materials. These materials are utilized for the fabrication and application of novel composite membranes or mixed-matrix membranes (MMMs), which present improved intrinsic and surface characteristics and, thus, can achieve high selectivity and permeability. Recent progress is described regarding the utilization of metal–organic frameworks (MOFs), carbon molecular sieves (CMSs), nanocomposite membranes, ionic liquid (IL)-based membranes and facilitated transport membranes (FTMs), which comprise MMMs. The most significant challenges and future prospects of implementing membrane technologies for CO2 capture are also presented.

“…Reprinted with permission of AIP Conference Proceedings from Tomas et al (2017) TSA techniques are often devoid of noise and vibration, but they typically involve adsorbents with sluggish conductivity, and the adsorption (cooling) and desorption (heating) cycle periods are rather lengthy (Akdag et al 2022, Gutierrez-Ortega et al 2022. Hence, hoover pressure may help regeneration.…”

The prevalence of indoor air pollution, primarily stemming from human activities, has led to increasing concerns regarding elevated CO2 concentrations in indoor environments. Prolonged exposure to such environments has been linked to reduced productivity, headaches, nausea, and more severe health risks, such as Sick Building Syndrome. Consequently, the development of efficient methods to reduce CO2 concentrations in indoor air is of utmost importance. This review offers a comprehensive analysis of cutting-edge indoor CO2 capture technologies, delving into the adsorption performance of solvents produced via various techniques. Our findings highlight the emergence of innovative materials that significantly enhance the indoor adsorption process; nevertheless, further investigation into reaction kinetics and stability remains imperative for continued progress. Among the methods assessed, Thermal Swing Adsorption and Wet Impregnation demonstrate superior suitability for indoor CO2 capture applications. Importantly, this review also emphasizes the potential of novel ventilation strategies, incorporating both internal ventilation and CO2 capture devices, to not only reduce indoor CO2 concentrations but also promote energy efficiency in buildings.

“…The capture of greenhouse gases, such as CO2, from dilute sources (e.g. flue gas which generally contains 4 -30 % CO2 in a mixture with N2) [3] has generally been achieved at an industrial scale using alkanoamines such as monoethanolamine (MEA) [4]. However, the chemical instability, their corrosiveness, and the cost of many alkanoamines limit their widespread application.…”

“…In contrast, adsorption-based processes for the capture and separation of CO2 using porous sorbents have been proposed as a promising energy-and cost-efficient alternative. Pressure-vacuum-and temperature-swing (PSVA, and TSA) adsorption have been explored at both lab-and pilot scales to successfully drive the capture and regeneration of CO2 in sorbents such as zeolites [6][7][8][9], porous carbons [3,10], and metal-organic frameworks (MOFs) /porous coordination polymers (PCPs) [11][12][13]. Although the running costs of such processes using porous sorbents offer significant benefits as compared to CO2 capture using amine compounds, problems with these techniques still exist and are related to e.g.…”

Efficient, facile, and energy-efficient desorption processes are highly sought after in industrial processes. Visible light exists all around us and can be considered a ubiquitous energy source that can be used to drive photothermal processes such as the release of guest molecules from porous sorbents. Herein, we present four sustainably synthesized porous coordination polymers, M(dhbq)(H2O)2 (where dhbq = 2,5-dihydroxy-1,4-benzoquinone, and M = Fe, Mg, Mn, or Zn) with visible light photoresponsive properties. Efficient desorption of CO2 corresponding to up to 47.6 % of the total uptake capacity was achieved upon visible light irradiation for 10 min. A negligible decrease (< 97 %) in CO2 uptake was observed for up to 10 light-swing adsorption cycles and working capacities of up to 37.5 g kg- were obtained in Fe(dhbq). M(dhbq) possess highly desirable properties that make them interesting for applications related to cost-effective and energy-efficient desorption processes.
