摘要
本文提出了一个包括16个集总组分的催化重整动力学模型,在氢气压力为(8～12)×10~5Pa、温度为460～500℃、氢油摩尔比为10的条件下测定了该模型的动力学参数.用最佳步长策略方法、Marquadt 方法及区域约束的参数估计方法估计出反应网络的动力学参数,计算出各个反应的活化能和频率因子.模型中各个组分的实验值与计算值的拟合很好,模型能较好地预测各组分的浓度分布.
A new catalytic reforming reaction network which contains 16 lumped components is proposed and the kinetic model is developed. The parameter estimation methods used are Marquadt method ,the best-step size method and area constraint method. The complex optimization method is also used for the determination of the initial values of kinetics constants. The experiments were conducted in a MR-80 microreactor with online GC analysis and under the conditions of 460,480,500℃ and 8,10,12kPa hydrogen pressure. The catalyst used is Pt-Sn/Al_2O_3. All measurements were made at constant activity and selectivity. The results predicted by the model fit the experimental data fairly well.
