摘　　要：以实验室建立的重油催化裂化(RFCC)12集总动力学模型为基础,通过设置装置因数和回炼计算,建立了重油催化裂化工业反应器模型。编制了可用于求取装置因数和预测产物分布的12集总动力学模型的工业模拟软件。基于实验室模型获得的动力学参数及工业装置操作数据,利用RK4(Runge-Kutta)法和拟牛顿BFGS(Broyden-Fletcher-Goldforb-Shanno)优化算法求取了工业装置因数。经验证,产物收率预测值与实际值的相对误差几乎均在5%以内,说明重油催化裂化工业反应器模型和装置因数的可靠性。考察了反应温度和剂油比(催化剂与原油质量比)对产物收率的影响,结果表明产物分布趋势的预测符合催化裂化反应规律,说明所建模型外推性良好,为模型的进一步工业应用打下了良好基础。Based on the 12-lumped kinetic model established in the laboratory for residue fluid catalytic cracking(RFCC),an industrial reactor model for RFCC was established by setting unit factors and recycle calculation.An industrial simulation software of the model for unit factors calculation and product distribution prediction was developed.Based on the kinetic parameters from the laboratory model and steady operation data from an industrial unit,the unit factors were calculated by combining the fourth order RK4(Runge-Kutta)method and the BFGS(Broyden-Fletcher-Goldforb-Shanno)optimization algorithm.It is proved that the relative errors between the calculated yields and the actual yields of the products are mostly within 5%,which indicates the reliability of the industrial reactor model established for RFCC and the unit factors.The effect of reaction temperature and mass ratio of catalyst to oil on product yields was also investigated.The prediction of product distribution trend by the software is consistent with catalytic cracking reaction rules.It is a good foundation for the further industrial application of the model.
