气液传质广泛存在于气体分离等化工过程中，强化气液传质有助于实现高效率低能耗的生产。在气液两相体系中加入第三分散相固体颗粒是强化气液传质的一个重要方法。该文对微米颗粒及纳米颗粒强化气液传质的实验和理论研究成果进行了总结与比较，对目前的研究中存在的问题进行了分析。在传统气液传质理论的基础上，阐述了3种被学者广泛认可的颗粒强化气液传质的机制，简单介绍了几个可以微观上解释颗粒强化气液传质现象的均相和非均相模型，比较了它们的使用范围和准确度。最后，在对已有文献综述的基础上对纳米颗粒强化气液传质的研究方向进行了展望。

Gas-liquid mass transfer is widespread in chemical industrial processes like gas separation. Enhancing gas-liquid mass transfer can help achieve production process with high efficiency and low energy consumption. It is an effective method to enhance gas-liquid mass transfer by adding the third dispersed solid particles. A review and comparison of the experimental and theoretical research results on gas-liquid mass transfer in the presence of fine particles were presented and existing problems were analyzed. Based on the traditional gas-liquid mass transfer theories, three widely accepted mechanisms explaining gas-liquid mass transfer enhancement caused by fine particles were introduced. Several homogenous and heterogeneous models developed for micro-explanation of the enhancement effect were discussed briefly, with their application scope and accuracy compared. Finally, the study directions in the field of gas-liquid mass transfer with nanoparticles were proposed based on the overview.
