摘　　要：滴流床反应器(TBR)动量传递模型的研究是改善传热、传质、反应效率及设计、强化反应器性能的基础。本文借助滴流床反应器相对渗透、单缝、双流体界面力等动量传递模型分析,探讨加氢反应床层压降、持液量变化趋势与模型模拟的差异,确定模型的适用体系与局限性,阐述了气液分布器结构差异对不同作用体系气液分布、反应过程的影响。结合滴流床反应器的工业实践,探索优化操作、强化反应强度,提高转化率、选择性的措施。The study of the momentum transfer model of trickle bed reactors is the basis to improve heat transfer, mass transfer, reaction efficiency, to design and enhance reactor performance. The tendency of pressure drop and liquid holdup and simulation differences of hydrogenation reaction are analyzed by momentum transfer models such as relative permeability models, single-slit models and two-fluid interfacial forces models to determine the applicable system and limitations of models, and to expound the influence of gas-liquid distributors＇ structure on the gas-liquid distribution and reaction process of different systems. The aim is to explore measures to increase conversion and selectivity of reactors.
