摘　　要：基于文献中的热态研究成果,总结了费托合成浆态床反应器模型的研究进展,并根据流动状态的理想性、气泡分类、模型的维度和模型研究方法对相关的研究工作进行了梳理和总结.经过分析归纳,认为费托合成浆态床反应器模型的复杂度日益提高,与实际反应情况越来越接近,结合CFD技术,以多维度、多气泡群、非理想流动为特征的模型是未来研究工作的趋势.对模型建立过程中必需的气液平衡和产物分布计算方法进行了系统的调研与分析,认为Henry定律适于合成气溶解度计算,而状态方程适于产物分布计算.Based on the thermal state research results in the literature, the research progress in mathematical modeling of slurry bed reactors for Fischer-Tropsch synthesis is reviewed, and the modeling is summarized from four aspects of ideality of flow, type of bubble, research dimension and method. By classification and analysis, it is found that the modeling is becoming much more complicated and closer to the reality. With the development of CFD technology, the models with multi-dimension, multi-bubble classes and non-ideal flow characteristics will be the trend of this field. The algorithms for vapor-liquid equilibrium of synthesis gas and the distribution of products between the gas and liquid phases are analyzed systematically. The Henry＇s law is suitable for the calculation of synthesis gas solubility, and the equations of state are well used to obtain the vapor-liquid equilibrium of products.
