【摘要】 在高剪切反应器（HSR）中研究了不同有机分散相对KHCO₃/K₂CO₃溶液吸收CO₂的强化效果,并考察了有机相与有机胺溶液复配使用对CO₂吸收率的影响。实验结果表明:环己烷、正庚烷对KHCO₃/K₂CO₃溶液吸收CO₂的强化效果明显,甲苯、正辛醇对KHCO₃/K₂CO₃溶液吸收CO₂则没有明显的强化效果;CO₂吸收率随HSR转速的增加而增加,随气液比、温度的增加而降低;环己烷对加入二乙醇胺活化的K₂CO₃溶液有较为明显的强化作用,CO₂吸收率最高可提高23%。与文献中不同反应器的对比表明HSR对CO₂具有较高的吸收效率。更多还原

【Abstract】 The intensification effect of different organic phases on the absorption of CO₂ by KHCO₃/K₂CO₃ solution in a high shear reactor（HSR） was investigated, and the combined effect of organic phase with organic amine on CO₂ absorption was also studied. The experimental results showed that cyclohexane and n-heptane exhibited significant intensification effect on the absorption of CO₂ by KHCO₃/K₂CO₃ solution, while the intensification effect of toluene and n-octanol on CO₂ absorption by KHCO₃/K₂CO₃ solution was negligible. CO₂ absorption percentage increased with the increase in the rotation speed of HSR and decreased with increasing gas-liquid ratio and temperature. CO₂ absorption by diethanolamine-activated K₂CO₃ solution was significantly enhanced by the addition of cyclohexane, with an increase of CO₂ absorption percentage up to 23%. HSR demonstrated a high efficiency for CO₂ absorption by a comparison with other reactors in the literature.更多还原
