研究了甘氨酸钠(SG)作为一种新型的二氧化碳吸收材料。实验测定了303.15、313.15和323.15 K下二氧化碳在平衡槽中二氧化碳分压范围内10、20和30质量%甘氨酸钠水溶液中的溶解度。结果表明，CO2的溶解度随甘氨酸钠溶液浓度的降低和温度的降低而增大。在所研究的压力范围内，它也随着CO分压的增加而增加。CO2在质量分数为10%的甘氨酸钠溶液中的溶解度优于MEA、AEPD、AMPD和TIPA。质量分数为20%和30%的甘氨酸钠溶液对二氧化碳的净吸收几乎相同。(C)2006爱思唯尔B.V.保留所有权利。
As a new absorbent for carbon dioxide, sodium glycinate (SG) was investigated in this study. The solubilities of CO2 expressed as loading capacity (mol CO2/mol SG) in aqueous 10, 20, and 30 mass% sodium glycinate solutions were measured experimentally at 303.15, 313.15, and 323.15 K over the partial pressure of carbon dioxide ranging from 0.1 to 200 kPa in an equilibrium cell. It was found that CO2 solubility increases with decrease in concentration of sodium glycinate solution and with decrease in temperature. It also increases with an increase in partial pressure of CO for the pressure range studied. The CO2 Solubility in 10 mass% sodium glycinate solutions was found to be better than other aqueous absorbents such as MEA, AEPD, AMPD, and TIPA. The net amount Of CO2 absorbed by 20 and 30 mass% sodium glycinate solution was almost same. (c) 2006 Elsevier B.V. All rights reserved.
