“…Carbon capture and storage is considered a presumable technology that can separate CO 2 from fossil fuels, thereby reducing the increasing carbon dioxide emissions into the atmosphere. Generally speaking, the traditional method for removing CO 2 is the 'wet method', namely chemical adsorption, which uses liquid ammonia solutions, such as monoethanolamine [4][5][6], diethanolamine [7,8], and diisopropanolamine [9,10]. However, solvent absorption methods have the disadvantages of severe equipment corrosion, high regeneration energy consumption, and decreased absorption capacity.…”

Various porous polymer materials have been prepared for the separation of CO2 from mixed gases. However, complex processes, expensive monomers, and costly catalysts are commonly used for their synthesis, making the adsorbents difficult to achieve in industrial applications. Herein, we developed a strategy to fabricate a series of benzene rings containing porous polymer materials (B-PPMs) via a facile condensation reaction of two inexpensive monomers, namely tetraphenylsilane and 1,4-bis(bromomethyl)benzene. The B-PPMs are verified to have accessible surface areas, large pore volumes, and appreciate pore sizes via a series of characterizations. The B-PPM-2 exhibits the best CO2 adsorption amount of 67 cm3·g−1 at 273 K and 1 bar, while the CO2/N2 selectivity can reach 64.5 and 51.9 at 273 K and 298 K, respectively. Furthermore, the adsorbent B-PPM-2 can be completely regenerated after five cycles of breakthrough experiments under mild conditions, which may provide promising candidates for selective capture of CO2 from mixtures.

“…Various CO 2 capture systems have been utilized to reduce these emissions, with chemical absorption being an established CO 2 removal process that utilizes aqueous alkanolamines 4 . Diethanolamine (DEA), monoethanolamine (MEA), triethanolamine (TEA), 2‐amino‐2‐methyl‐1‐propanol (AMP), and N‐Methyldiethanolamine (MDEA) are examples of alkanolamines 5,6 . Because of its higher absorption capacity and CO 2 reactivity, MEA is used as a benchmarking absorbent in the post‐combustion CO 2 collection process.…”

The physical properties such as density, surface tension, and viscosity of monoethanolamine (MEA)-ionic liquids (ILs) solvent mixtures were studied experimentally in this work. The ILs namely, tetrabutylammonium acetate TBAAc, tetrabutylammonium bromide TBABr, and tetrabutylammonium hydroxide TBAOH were used. All the above parameters were measured at atmospheric pressure and various temperatures from 283 to 313 K with a 10 K interval.From the measured experimental data, thermodynamic properties such as thermal expansion, excess molar volume, viscosity deviation, and excess Gibbs free energy were also calculated. The physical and thermodynamic properties are more important to understand the solvent behavior during solvent screening in solvent-based CO 2 capture process. The 30 wt% solvent mixture composition was prepared as 28, 25, and 20 wt% MEA mixed with 2, 5, and 10 wt% ILs. Furthermore, a single empirical model was developed from the measured experimental data and the results are correlated. A good agreement was obtained between correlated and experimental data.
