    Establishment of Combined Model for Lumped Reaction Kinetics of FDFCC

      摘要
    • 摘要: 从灵活双效催化裂化（FDFCC）工艺特点和反应机理出发，以其工业提升管实际操作参数为基础，对该工艺的两个子反应体系——重油提升管和汽油提升管分别进行研究并提出了相应的重油12集总、汽油9集总催化裂化动力学模型。详细分析了重油、汽油反应体系与总反应体系相应集总组分的数学关联，提出了FDFCC工艺反应动力学组合模型。最后，采用不同原料、不同操作条件下的两组工业实测数据对该模型进行了验证。结果表明：模型计算值和实测值能很好地吻合(总物料组成的绝对误差除个别点外均在1%以下)。该模型能较好地预测产品分布及性质，对FDFCC工艺的工业装置操作优化具有指导意义。

       

      Abstract: Two reaction subsystems of flexible dualriser fluid catalytic crackling(FDFCC) process, heavy oil and gasoline FCC reaction system, were studied. A -12-lump kinetic model for heavy oil FCC and a 9-lump one for gasoline FCC were presented based on the reaction mechanism and the industrial operation parameters. The mathematical correlation between the two models was analyzed in detail for FDFCC process. A combined kinetic model for FDFCC was established and verified by two sets of commercial data with different feedstocks and operating conditions. The results showed that the model-calculated values were close to those of the industrial data. The model could predict the unit production well and guide the optimization of the operating conditions for FDFCC process.
