摘　　要：介绍了一种用于计算催化裂化催化剂流化再生反应过程的数学模型。在流体力学方程组中,加入催化剂再生反应动力学方程,构成了再生过程流化反应模型。用该模型对在提升管再生器中的再生过程进行了模拟计算,分析了再生器中的温度场和速度场。与流场试验数据相比较,结果显示出两者之间有较好的一致性。A mathematical model for computing FCC catalyst fluidizing regeneration process is presented. The model was established by incorporating the dynamic equation of catalyst regeneration with the hydrodynamic equations. With this model, simulations were implemented for a riser regenerator, and the velocity field and temperature field in the regenerator were calculated and analyzed. The calculation result showed that the model was consistent with the experimental data.
