This is the first work to investigate the hydrodynamics and gas-liquid mass transfer of carbon dioxide (CO₂) absorbed into the amino-functionalized ionic liquid (IL) [NH₂e-mim][BF₄] and monoethanol-amine (MEA) mixture through a vertical circular monolith channel by means of computational fluid dynamics (CFD). It is shown that there are five flow patterns (i.e., bubbly flow, Taylor flow, slug-bubbly flow, slug-annular flow, and annular flow), and Taylor flow is the main flow pattern. The intrinsic kinetics of CO₂ absorbed into the [NH₂e-mim][BF₄]-MEA mixture was obtained, the reaction orders relative to CO₂, [NH₂e-mim][BF₄], and MEA being 1, and the activation energy E_a (19,313 and 28,991 J•mol⁻¹) and pre-exponential factor k₀ (3.34×10⁵ and 7.04×10⁶ mol^-1•L•min⁻¹) for CO₂ absorbed in [NH₂e-mim][BF4] and MEA were derived. After the kinetic parameters were imported into the mass transfer model, it was found that the liquid phase volumetric mass transfer coefficient (k_La) in the presence of a chemical reaction can be improved by three to eight times, indicating that mass transfer can be enhanced remarkably by chemical reaction. Moreover, a correlation formula is developed to predict k_La, which agrees well with the simulation results. This work provides a new way to capture CO₂ with the combination of IL and MEA in a monolith reactor.

这是研究吸收到氨基官能化离子液体（IL）[NH ₂ e-mim] [BF ₄ ]和单乙醇胺（MEA ）中的二氧化碳（CO ₂）的流体动力学和气液传质的第一项工作。）通过计算流体动力学（CFD）通过垂直圆形整体通道进行混合。结果表明，存在五种流动方式（气泡状流动，泰勒流动，弹状气泡流动，弹状环状流动和环形流动），而泰勒流动是主要的流动形态。获得了被[NH ₂ e-mim] [BF ₄ ] -MEA混合物吸收的CO ₂的内在动力学，反应顺序相对于CO ₂，[NH ₂ e-mim] [BF₄ ]，MEA为1，活化能E _a（19,313和28,991 J•mol ^-1）和指数前因子k ₀（3.34×10 ⁵和7.04×10 ⁶ mol ^-1 •L•min ^-1）求出[NH ₂ e-mim] [BF4]和MEA中吸收的CO ₂。将动力学参数导入传质模型后，发现在存在化学反应的情况下，液相体积传质系数（k _L a）可以提高三到八倍，表明传质可以进行。通过化学反应显着增强。此外，开发了相关公式来预测k_L a，与仿真结果非常吻合。这项工作提供了一种在整体反应器中结合IL和MEA捕获CO ₂的新方法。
