纳米TiO2颗粒强化MDEA溶液鼓泡吸收CO2的特性
CO2 bubble absorption performance enhancement by TiO2 nanoparticles in MDEA solution
摘要
Abstract
In order to enhance the absorption of CO2 in the N-methyldiethanolamine (MDEA) solution,stable nanofluids (the mass fraction of MDEA is 50％ and the mass fraction of TiO2 nanoparticles are 0.05％,0.2％,0.4％ and 0.8％) without any dispersant were prepared.The influence of nanoparticles mass fraction on CO2bubble absorption in the MDEA solution was studied.The amount of CO2 absorbed by the solution was measured by the weighing method,and the relative errors of the experiment results were analyzed.The experimental results show that the absorption of CO2 in the MDEA solution is enhanced by the addition of TiO2 nanoparticles and the effective absorption ratio increases with the increase of TiO2 nanoparticles mass fraction.The results show that the effective absorption ratio can reach 1.0195,1.0653,1.0779 and 1.1154 when the mass fraction of TiO2 nanoparticles are 0.05％,0.2％,0.4％ and 0.8％,respectively.The possible mechanisms of the results and phenomena in the experiments are also explained.关键词
