Micro-packed bed reactors, due to their high mass and heat transfer efficiency, and inherent safety, have significant advantages in processes such as hydrogenation reactions, debenzylation reactions, and catalyst screening. Despite extensive studies on gas–liquid two-phase flow in micro-packed beds, research on gas–liquid–liquid three-phase flow remains limited. This study investigates the mass transfer and pressure drop behaviors of gas–liquid–liquid three-phase flow in micro-packed beds. Experimental results reveal that gas–liquid mass transfer is influenced by dispersion and turbulence enhancements, as well as the secondary liquid phase. A mathematical model for mass transfer shows strong agreement with experimental data. Additionally, a pressure drop model, considering inertial, viscous, and interfacial tension forces, accurately predicts experimental results. These findings provide valuable insights for optimizing micro-packed bed operations.

微填充床内气液液三相流的气液传质及压降行为


微填充床反应器由于其传质传热效率高以及固有的安全性，在加氢反应、脱苄基反应、催化剂筛选等过程中具有显着的优势。尽管对微填充床中气液两相流进行了广泛的研究，但对气液液三相流的研究仍然有限。本研究研究了微填充床中气-液-液三相流的传质和压降行为。实验结果表明，气液传质受到分散和湍流增强以及二次液相的影响。传质数学模型与实验数据非常吻合。此外，考虑惯性、粘性和界面张力的压降模型可以准确预测实验结果。这些发现为优化微型填充床操作提供了宝贵的见解。
