“…compares the activation energy obtained in the present work with values for different ILs in the literature . A few observations can be made: (i) ILs in the presence of other solvents, such as MEA, AMP, aprotic heterocyclic anions (AHA) or water, have higher activation energies than the value obtained herein ; and (ii) when ILs were not mixed with other solvents, the reported activation energy agreed with the value calculated in this work. For the same [P 66614 ] cation, Burkan et al reported activation energies of 18 and 11 kJ mol −1 for the anions [3‐CF3pyra] and [2‐CNpyr], respectively .…”

Post-combustion processes based on ionic liquids (ILs) and membrane contactors are attractive alternatives to traditional systems. Here, a gas stream composed of 15 % CO 2 and 85 % N 2 flowed through the lumen side of a hollow-fiber membrane contactor containing poly(vinylidene fluoride)-IL (PVDF-IL) fibers. The IL 1-ethyl-3-methylimidazolium acetate [emim][Ac] served as an absorbent due to its high chemical absorption and CO 2 solubility. The overall mass transfer coefficient (K overall ), activation energy (E a ), and resistances of the hollow-fiber membrane were quantified. The K overall value was one order of magnitude higher than those reported in previous works with conventional solvents, and the E a was lower than formerly stated values for other solvents. A theoretical simulation was conducted to estimate the operational parameters required for 90 % CO 2 capture and to quantify intensification effects related to CO 2 absorption in a packed column.

The surface tension and viscosity values of N-methyldiethanolamine (MDEA) aqueous solutions promoted by tetramethylammonium arginate ([N1111][Arg]) were measured and modeled. The experimental temperatures were 303.2 to 323.2 K. The mass fractions of MDEA (wMDEA) and [N1111][Arg] (w[N1111][Arg]) were 0.300 to 0.500 and 0.025 to 0.075, respectively. The measured surface tension and viscosity values were satisfactorily fitted to thermodynamic models. With the aid of experimentally viscosity data, the activation energy (Ea) and H2S diffusion coefficient (DH2S) of MDEA-[N1111][Arg] aqueous solution were deduced. The surface entropy and surface enthalpy of the solutions were calculated using the fitted model of the surface tension. The quantitative relationship between the calculated values (surface tension, surface entropy, surface enthalpy, viscosity, activation energy, and H2S diffusion coefficient) and the operation conditions (mass fraction and temperature) was demonstrated.

In this study, seven amino acid-based poly(ionic liquid)s (AAPILs) such as poly(1-butyl-3-vinylimidazolium glycinate), P[VBIm][Gly], poly (1-butyl-3-vinylimidazolium alaninate), P[VBIm][Ala], poly(1-butyl-3-vinylimidazolium valinate), P[VBIm][Val], poly(1-butyl-3-vinylimidazolium prolinate) P[VBIm][Pro], poly(1-butyl-3-vinylimidazolium hisdinate), P[VBIm][His], poly(1-butyl-3-vinylimidazolium lysinate), P[VBIm][Lys], and poly(1-butyl-3-vinylimidazolium arginate), P[VBIm][Arg] have been synthesized, characterized, and their CO2 absorption capacities were investigated using quartz crystal microbalance (QCM) at temperature range 288.15–308.15 and pressures up to 5 bar. Based on the absorption mechanism, the reaction equilibrium thermodynamic model is applied to correlating the experimental CO2 absorption capacities. The reaction equilibrium constant and Henry’s law constant were calculated to evaluate the efficiency of the AAPILs for CO2 absorption. In the investigated AAPILs, the CO2 absorption capacity was as follows: P[VBIm][Arg] > P[VBIm][Lys] > P[VBIm][His] > P[VBIm][Pro] > P[VBIm][Gly] > P[VBIm][Val] > P[VBIm][Ala]. The accessibility of available more amine groups in AAPIL with arginate anion is the main factor for the high CO2 absorption capacity. Also, chemical absorption of CO2 via carbamate formation was corroborated by FT-IR spectroscopy.
