| 中文摘要: |
| 本文通过一步合成法合成了四种不同摩尔比的TEAC-MEA DES，测定了其热稳定性，发现此DES热稳定性高；通过五次的吸收/解吸循环发现，合成的DES具有重复使用性能较好，再生效率高；通过lnK对1/T线性拟合发现DES吸收CO2的吸收焓为负，由此可以得出，TEAC-MEA DES吸收CO2是放热过程，此DES是非常有潜力的CO2吸收剂。 |
| 英文摘要: |
| In this paper, four kinds of TEAC-MEA DES with different molar ratios were synthesized by a one-step synthesis method, and their thermal stability was measured, and it was found that this DES had high thermal stability; through five absorption/desorption cycles, it was found that the synthesized DES had reusability. It is better, and the regeneration efficiency is high; through the linear fitting of lnK to 1/T, it is found that the absorption enthalpy of CO2 absorbed by DES is negative. It can be concluded that the absorption of CO2 by TEAC-MEA DES is an exothermic process, and this DES is very Potential CO2 absorbent. |
