“…2). In conventional amine solutions, the base is a second amine molecule; thus two amines capture one carbon dioxide (32,33). In amyloid fiber materials, we observed 1:1 stoichiometry where one amine binds to one carbon dioxide.…”

New materials capable of binding carbon dioxide are essential for addressing climate change. Here, we demonstrate that amyloids, self-assembling protein fibers, are effective for selective carbon dioxide capture. Solid-state NMR proves that amyloid fibers containing alkylamine groups reversibly bind carbon dioxide via carbamate formation. Thermodynamic and kinetic capture-and-release tests show the carbamate formation rate is fast enough to capture carbon dioxide by dynamic separation, undiminished by the presence of water, in both a natural amyloid and designed amyloids having increased carbon dioxide capacity. Heating to 100 °C regenerates the material. These results demonstrate the potential of amyloid fibers for environmental carbon dioxide capture.

“…Unlike monoethanolamine (MEA), EAE has a small corrosion rate, even at higher concentrations. In addition, it requires less energy for regeneration, and the absorption rate is higher due to creation of moderate stability carbamate [5][6][7][8]. An additional advantage is that, produced from agriculture products or residues ethanol is used to produce ethylamine and ethylene oxide.…”

“…Both those chemicals react to form EAE [9]. Moreover, methyldiethanolamine (MDEA) is often applied during amine washing to ensure H 2 S removal [2], however its rate constant of second-order reaction is lower than for EAE [8], and existing biogas power plants already removed H 2 S prior to combustion at CHP unit [1,2]. 2-(Ethylamino)ethanol has been already proved as an absorbent for CO 2 capture [9], and also as an activator in aqueous N,N-diethylethanolamine (DEEA) solutions [10].…”

“…2-(Ethylamino)ethanol has been already proved as an absorbent for CO 2 capture [9], and also as an activator in aqueous N,N-diethylethanolamine (DEEA) solutions [10]. However, there is still little experimental data on CO 2 capture with EAE at high loading rates (mol CO 2 mol EAE -1 > 1), and while the focus was rather on kinetics of reaction [8][9][10][11][12], no publication on thermodynamic modelling representing vapour-liquid equilibrium in the CO 2 -EAE -H 2 O system was found. Therefore in this research the Electrolyte Non Random Two-Liquid (eNRTL) model was applied for modelling the EAE's performance, since it has been widely applied for other amines like MEA [13], MEA and DEA [14], DGA [15], DGA and MDEA [16].…”

Carbon dioxide solubility was studied in 2.5 mass % and 5 mass % aqueous 2 (Ethylamino)ethanol (EAE; CAS 110-73-6) solution, an interesting secondary amine prepared mainly from renewable resources, at high loading rates, at three temperature ranges (293.00K, 313.15 K, 333.15 K), and in pressure range from 289 to 1011 kPa. In addition to that, heat capacity (cp) was measured of examined solution, allowing determination of temperature dependent coefficients of ideal gas heat capacity equation. Afterwards, the electrolyte Non Random Two-Liquid model's parameters were determined to represent the thermodynamic behaviour of the CO 2 -EAE -H 2 O system with use of ASPEN® Plus V8.0 simulation software, indicating a good correlation between experimental and simulation results. As a consequence, model based calculation of the carbon dioxide capture with use of 2- (Ethylamino)

“…N-Ethylethanolamine (EEA) represents a candidate amine having good potential for bulk removal of CO 2 from gaseous streams. Mimura et al [2] studied the kinetics of the reaction between CO 2 and EEA in aqueous solutions and reported second-order reaction rate constants comparable to MEA at 298 K. Li et al [3] observed that the reaction rate in aqueous EEA was faster than that in DEA. EEA is formed from ethylamine (obtained from ethanol) and ethylene oxide (obtained from the oxidation of ethylene, which in turn can be prepared by dehydration of ethanol).…”

N-Ethylethanolamine (EEA) and N,N-diethylethanolamine (DEEA) represent promising candidate alkanolamines for CO 2 removal from gaseous streams, as they can be prepared from renewable resources. In this work, the reaction rate constant for the reaction between CO 2 and EEA was determined from the absorption rate measurements of CO 2 in a blend comprising DEEA, EEA and H 2 O. A stirred-cell reactor with a plane, horizontal gas-liquid interface was used for the absorption studies. While the DEEA concentration in the formulated solution was varied in the range of 1.5-2.5 kmol/m 3 , the initial EEA concentration was 0.1 kmol/m 3 . A zwitterion mechanism for EEA and a base-catalyzed hydration mechanism for DEEA were used to describe the reaction kinetics. At 303 K, the second-order reaction rate constant for the CO 2 reaction with EEA was found to be 8041 m 3 /(kmol s). The liquid-side mass transfer coefficient was also estimated, and its value (0.004 cm/s) is in line with those typical of stirred-cell reactors.
