摘要

化学吸收法是重要的CO

捕集技术，其中少水吸收剂因具有捕集速率较快、CO

吸收负荷较高和再生能耗较低等优点而被广泛研究。以1

3-丙二胺（DAP）/四甲基乙二胺（TMEDA）/H

O为基础的化学吸收剂具有良好的CO

捕集性能，而利用物理溶剂替换部分H

O所得胺类少水吸收剂可进一步降低再生能耗。在DAP/TEMEA/H

O中加入二乙二醇二甲醚（DMEDEG），制得胺类少水吸收剂DAP/TEMEA/DMEDEG/H

O。研究了

(DMEDEG):

O)对DAP/TEMEA/DMEDEG/H

O CO

吸收、解吸性能的影响，采用核磁共振技术和量子化学计算分析了DAP/TMEDA/DMEDEG/H

O的反应和分相机理，并研究了DAP/TMEDA/DMEDEG/H

O的腐蚀性和再生能耗。结果表明，将DAP/TMEDA/DMEDEG/H

O中DAP + TMEDA质量分数固定为50%，当

(DMEDEG):

O)为1:9时，DAP/TMEDA/DMEDEG/H

循环负荷（3.549 mol/kg）；DAP与CO

反应主要生成氨基甲酸酯（DAPCOO

），并且中间产物（DAP

COO

）更容易使TMEDA质子化；一定条件下腐蚀20#碳钢试片7 d，DAP/TMEDA/DMEDEG/H

O的缓蚀率为-1.035；相同条件下，DAP/TMEDA/DMEDEG/H

Abstract

Chemical absorption is an important CO

capture technology

among which water-lean absorbent has been widely studied due to their advantages of fast capture rate

high CO

absorption capacity and low regeneration energy consumption

etc. Chemical absorbent based on 1

3-diaminopropane (DAP)/tetramethylethylenediamine (TMEDA)/H

O exhibits excellent CO

capture performance

while the amine water-lean absorbent prepared by replacing part of H

O with physical solvent can further reduce regeneration energy consumption. Amine water-lean absorbent DAP/TMEDA/DMEDEG/H

O was prepared by the addition of diethylene glycol dimethyl ether (DMEDEG) to DAP/TMEDA/H

O. Effect of

(DMEDEG):

O) on the CO

absorption and desorption performance of DAP/TMEDA/DMEDEG/H

O was investigated. Nuclear magnetic resonance (NMR) and quantum chemical calculation were used to analyze the reaction and phase-separation mechanisms of DAP/TMEDA/DMEDEG/H

O. Additionally

the corrosiveness and regeneration energy consumption of DAP/TMEDA/DMEDEG/H

O were studied. The results show that

by fixing the DAP + TMEDA mass fraction in DAP/TMEDA/DMEDEG/H

O at 50%

DAP/TMEDA/DMEDEG/H

O exhibits the maximum CO

cyclic load (3.549 mol/kg) with

(DMEDEG):

O) of 1:9. The reaction between DAP and CO

mainly produces carbamate (DAPCOO

)

and the intermediate product (DAP

COO

) facilitates the protonation of TMEDA. After 7 d of corrosion of 20# carbon steel sample under certain conditions

the corrosion rate of DAP/TMEDA/DMEDEG/H

O is -1.035. Under certain conditions

the regeneration energy consumption of DAP/TMEDA/DMEDEG/H

O (approximately 4.13 GJ/t) is slightly lower than the regeneration energy consumption (approximately 4.20 GJ/t) of monoethanolamine with mass fraction of 30%.
