摘　　要：研究了气升式反应器中冷模的流体力学性质,提出了气升式反应器的气液接触模型,即混合池模型。将实验室规模的气升式反应器依照燕山化工二厂异丙苯氧化反应的生产能力进行了放大。利用此模型结合传质方程和反应模型,模拟气升式反应器内进行的异丙苯氧化反应的反应状况,并与鼓泡塔进行比较,模拟结果优于鼓泡塔的反应结果。In this paper, the hydrodynamic characteristics of cold-model in airlift reactor are studied and the mixing-cell model of airlift reactor is put forward. According to the capacity of isopropyl benzene oxidation reaction in Yansan chemical factory, the airlift reactor in our laboratory is amplified. The mixing-cell model is combined with mass transfer equation and reaction model, and isopropyl benzene oxidation reaction in the amplified airlift reactor is simulated. The simulation result is superior to the actual outcome of bubble column.
