AIChE Journal, Journal Year: 2023, Volume and Issue: 69(12)

Published: Aug. 24, 2023

Abstract This study explored diethanolammonium chloride ([DEA]Cl) as a potential ionic liquid from low‐cost and commercial ones for gas separation. There are three kinds of functional sites in [DEA]Cl: acidic NH 2 + , hydrogen‐bond OH, nucleophilic Cl − . The separation NH 3 /N /H SO /CO H S/CO /CH 4 was considered, because the mixtures extensively involved many industrial processes. experimental results demonstrated that [DEA]Cl exhibited excellent ability to separate mixture also proper capacity but inferior. theoretical calculations revealed OH worked synergistically contribute with contributing provides basis application area

Because of increasing atmospheric anthropogenic ammonia (NH3) emission, researchers are devising new techniques to capture NH3. Deep eutectic solvents (DESs) found as potential media for NH3 mitigation. In the present study, we have carried out ab initio molecular dynamics (AIMD) simulations decipher solvation shell structures an solute in reline (1:2 mixture choline chloride and urea) ethaline ethylene glycol) DESs. We aim resolve fundamental interactions which help stabilize these DESs, focusing on structural arrangement DES species nearest around solute. reline, hydrogen atoms preferentially solvated by anions carbonyl oxygen urea. The nitrogen atom renders bonding with hydroxyl cation. positively charged head groups cations prefer stay away from ethaline, strong interaction exists between glycol. be glycol While molecules play a crucial role solvating NH3, remain passive deciding first shell. both approach their group side. observe slightly stronger solute-solvent charge transfer than those reline.

It has been of long concern that the separation and recovery NH3 from industrial processes, in addition to attracting huge economic interest, also reduce environmental pollution. So, it is very urgent develop novel absorbents for highly efficient capture NH3. In this study, several tetrazole (TetrZ)-based binary deep eutectic solvents (DESs) were formed by mixing TetrZ with 1,2,3-triazole (1,2,3-Tri), ethylene glycol (EG), 2-morpholinoethanol (2-Mor), or N-methyldiethanolemine (MDEA) absorb + 1,2,3-Tri (1:4, mole ratio) not only exhibits higher absorption ability 0.239 gNH3·gDES–1 than most reported date at 313.15 K 101.3 kPa, but shows elevated selectivities 592.7 NH3/CO2, 654.5 NH3/N2, 1033.7 NH3/O2. Meanwhile, (1:4) can be reused 10 times good capacity retained. Additionally, solubility data correlated reaction equilibrium thermodynamic model. The NMR FTIR spectroscopic characterizations used study mechanism, quantum chemistry calculation was utilized further investigate interactions between DESs an atomic level perspective. developed present work have potential sustainably, owing their high solubility, superior selectivity, desirable reversibility.
