doi:10.16085/j.issn.1000-6613.2019-1392

Abstract

Abstract:

Aqueous 2-(2-aminoethylamino) ethanol (AEE) solution is an efficient CO₂ absorbent with a high CO₂ capacity of 1.2molCO₂/molAEE, high CO₂ reaction rate and stable chemical properties. However, the application of this technology is affected by low CO₂ desorption rate and desorption loading (0.8 molCO₂/molAEE). Modified titanium oxides were found to be able to enhance desorption of AEE aqueous solution at the mass fraction of 0.05%～0.20%. Based on absorption (40℃)-desorption (120℃) experiment results, the performance of modified titanium oxides (TiO₂-MWCNT＞TiO₂-OH) was superior to TiO₂ that has been reported. The maximum desorption rates of AEE added with TiO₂-MWCNT and TiO₂-OH were 0.093L/min (0.15%) and 0.083L/min (0.20%), respectively. Compared with pure aqueous AEE solution, the increase of AEE desorption rate with TiO₂-MWCNT and TiO₂-OH is 32.9% and 18.6%, respectively. The desorption amounts were 0.92molCO₂/molAEE (0.15%) and 0.88molCO₂/molAEE (0.20%), which increased by 12.2% and 9.7%, respectively. The cyclic absorption capacity were 0.95 molCO₂/molAEE (0.15%) and 0.89molCO₂/molAEE (0.15%), which increased by 18.75% and 11.25%, respectively. Five cycle absorption and desorption results showed that the enhancement is durable, which demonstrates stable chemical properties of modified TiO₂. The modified TiO₂ was characterized by XRD, BET, FTIR and SEM after reaction, which showed stable structure. Above all, TiO₂-MWCNT and TiO₂-OH are potential to be applied to enhancing CO₂ desorption from aqueous AEE solution in industry.

摘要：

羟乙基乙二胺（AEE）水溶液的CO₂循环吸收量高（1.2molCO₂/molAEE），吸收速度快，稳定性好，但解吸速度慢、解吸量少（0.8mol CO₂/mol AEE）是限制该技术广泛应用的主要原因。本文通过向AEE水溶液中添加质量分数为0.05%～0.20%的改性氧化钛（TiO₂-MWCNT和TiO₂-OH）强化AEE的解吸能力。CO₂循环吸收（40℃）-解吸（120℃）实验结果表明改性氧化钛的添加比氧化钛强化CO₂解吸效果更好，强化顺序为TiO₂-MWCNT＞TiO₂-OH；其对应的最大解吸速率分别为0.093L/min（质量分数0.15%）和0.083L/min（质量分数0.20%），相对于AEE水溶液，分别提高了32.9%和18.6%；其对应的最大解吸量分别为0.92molCO₂/molAEE（质量分数0.15%）和0.88molCO₂/molAEE（质量分数0.20%），分别提高了12.2%和9.7%；其对应的CO₂循环吸收量分别是0.95molCO₂/molAEE（质量分数0.15%）和0.89molCO₂/molAEE（质量分数0.15%），分别提高了18.75%和11.25%；5次循环吸收解吸实验结果表明改性氧化钛强化CO₂解吸效果稳定，具有较强的化学稳定性。对反应后的改性氧化钛进行XRD、BET、FTIR和SEM表征，结果表明改性氧化钛具有较强的结构稳定性。TiO₂-MWCNT和TiO₂-OH在促进有机胺溶液解吸CO₂方面具有一定的工业应用潜力。
