| 英文摘要 | Deep eutectic solvents (DESs) are a class of green solvents that hold promising application in gas separation. With respect to NH3 separation, reversible chemical absorption of NH3 is in demand, as the contents of NH3 in industrial streams are normally low, making traditional means of NH3 separation inefficient. In this study, we found that N-methylacetamide (MAA) can form DESs with heterocyclic weak acids (HWAs) such as imidazole, 1,2,4-triazole, and tetrazole. The DESs were characterized by their physical properties and systematically evaluated for NH3 absorption performance. The solubilities of NH3 in MAA+tetrazole DESs are much higher than those in MAA+imidazole and MAA+triazole DESs, since tetrazole is more acidic than the latter two HWAs. In addition, the isotherms for NH3 absorption in MAA+tetrazole DESs display nonideal profiles, suggesting the chemical behavior of NH3 absorption, which is further elucidated by theoretical calculations and spectroscopic characterizations. Overall, MAA+tetrazole DESs are among the best solvents for NH3 absorption, with a NH3 solubility of 4.60 mol/kg at 313.2 K and 9.0 kPa. The absorption of NH3 in MAA+tetrazole DESs also shows excellent selectivity for CO2 and good reversibility throughout consecutive cycles, justifying the potential use of MAA+tetrazole DESs for NH3 separation from industrial streams. |
