摘要:
为了强化N-甲基二乙醇胺(MDEA)溶液对CO2的吸收,首先制备了分散稳定性良好的TiO2-MDEA-H2O纳米流体.然后用测量气体压降的方法对纳米流体(MDEA质量分数为50%,纳米颗粒质量分数分别为0.1%和0.4%)气/液界面吸收CO2的特性进行了实验研究.结果显示,随着温度的上升,MDEA溶液对CO2的吸收速率增大,纳米颗粒的加入提高了溶液对CO2的吸收速率.在10℃时,CO2的吸收速率随着颗粒质量分数的上升而增大,但是在20和30℃时,纳米颗粒质量分数为0.1%和0.4%的纳米流体对CO2吸收速率的差异逐渐减小.强化吸收的有效吸收比范围为1.03~1.14,最后对强化机理进行了探讨.
Abstract:
In order to enhance the absorption of CO2 in the N-methyldiethanolamine(MDEA)solution, stable TiO2-MDEA-H2O nanofluids were prepared. The CO2 absorption characteristics in the gas/liquid interface of nanofluids(the mass fraction of MDEA is 50% and the mass fraction of TiO2 nanoparticles are 0.1% and 0.4%)were studied by measuring the absolute pressure drop of gas. The results indicate that the CO2 absorption rate increases with the increase of temperature and it is enhanced by the addition of nanoparticles. At 10℃, the CO2 absorption rate increases with the increase in the nanoparticle mass fraction. However, at 20℃ and 30℃, the difference of CO2 absorption rate in two different nanoparticle mass fractions(0.1% and 0.4%)reduces gradually. The effective absorption ratio ranges from 1.03 to 1.14. The possible enhancement mechanisms in experiments are discussed.
