In the CO2 capture process, decreasing the energy consumption and increasing the desorption rate of loaded MEA-CO2 during the regeneration process of monoethanol amine have been identified as major challenges that need to be addressed. To overcome these challenges, three modified heterogeneous mesoporous catalysts, CMK-3-SiO2, CMK-3-MCM-41, and CMK-3-SBA-15, and a SO4 2–/ZrO2 solid acid catalyst were initially synthesized and investigated to determine their catalytic effectiveness in the process of CO2 and MEA solvent regeneration with a CO2 loading of 0.5 ± 0.02 mol CO2/mol MEA at 97 °C. According to the experimental results, the CMK-3-modified catalyst significantly decreased the energy requirement for CO2 desorption. The catalytic performance of the synthesized catalysts was in the order of CMK-3-SiO2 > CMK-3-MCM-41 > CMK-3-SBA-15 > SZ. CMK-3-SiO2 exhibited the best catalytic performance by enhancing the desorption rate by 195%, and decreasing the energy requirement by 37.41% compared to monoethanol amine as a blank run. Furthermore, the CMK-3-SiO2 catalyst exhibited the best catalytic performance compared to the literature with excellent stability and no unfavorable effects on the MEA-CO2 absorption activity for the regenerated amine solvent. This performance seems to be a result of the large mesoporous surface area (BET) and the large number of Brϕnsted and Lewis acid sites. In addition, a reasonable reaction mechanism for amine solvent regeneration with the CMK-3 heterogeneous catalyst is proposed.

“…2 The current state-ofthe-art technology in the CO 2 capture is the use of basic amine solutions as a scrubber though this methodology is associated with several critical shortcomings such as high regeneration energy, amine volatility and corrosivity and high maintenance cost of the setup. 3,4 The past century has witnessed a lot of effort in quest of ''green and sustainable'' solvents alternative to volatile organic solvents. Among them, ionic liquids (ILs) and deep-eutectic solvents (DESs) have garnered maximum attention, as they have the potential to be utilized in various applications because of their advantageous properties such as often insignificant vapour pressure, high thermal stability, a wide liquidus range, low flammability and good recyclability.…”

Post-combustion carbon capture (PCC) using membrane technology is a rising alternative to PCC processes, which is based on conventional equipment, such as CO2 absorptiondesorption in packed columns, to mitigate human-associated climate change. Research on CO2 capture system has been centered on improving the CO2 absorption process efficiency, while little attention has been devoted to the performance of the solvent regeneration technology.In this review, research development is focused on the performance of the CO2 desorption process using hollow fiber membrane contactors (HFMCs). The main impact factors in membrane contactor technology are presented, including solvent and membrane material selection, membrane module design, mass transfer correlations, operational issues, modeling and simulations. Each section has been discussed in terms of its current status while describing future challenges to improve the technology for its industrial implementation.
