| 摘 要： | 在双搅拌反应釜中研究了位阻胺2-氨基-2-甲基-1-丙醇(AMP)与甘氨酸钠(SG)混合溶液吸收CO2的性能.实验温度293~313K,混合溶液的浓度为AMP(1.5kmol/m3)+SG (0.2,0.4,0.6,0.8kmol/m3),SG浓度每增加0.2kmol/m3,200min内的平均吸收速率分别提高11.47%,10.07%,9.18%和5.33%.与AMP单一溶液相比,混合溶液在200 min时的吸收容量增加了11.5%~41.1%.在293~313K,吸收速率随温度上升而提高.使用加热的方法进行再生实验,得到1.5 kmol/m3 AMP + 0.6 kmol/m3 SG混合液的最适再生温度为378K.AMP + SG混合溶液的再生效率高于单一SG溶液及AMP + MEA/DEA混合溶液.

| Abstract: | The absorption of carbon dioxide into aqueous blends of 2-amino-2-methyl-1-propanol(AMP) and sodium glycinate(SG) was investigated from 293k to 313k in a double stirred-cell contactor.Five systems of which 1.5 kmol/m3AMP mixed with various SG concentrations(0.2,0.4,0.6 and 0.8 kmol/m3) were studied.The average CO2 absorption rates increased(11.47%,10.07%,9.18% and 5.33%) with an increase of SG concentrations(0.2 kmol/m3 SG at a time).Compared to 1.5 kmol/m3 AMP,the blends had an increase of absorption capac... |
