摘要：根据F-T合成蜡油加氢裂化过程的机理及已有的九集总和全集总动力学模型,提出了异构化因子的概念;将异构化反应模拟与实验结果相结合,引入裂化概率函数改进原有九集总动力学模型;据此建立了包含7个反应式的更加符合实际加氢裂化过程的五集总动力学模型。通过已有的实验结果同两种动力学模型的比较,表明所建立的五集总动力学模型计算值与实验值的平均相对误差为3.95%,在高转化率的情况下,平均相对误差仅为0.88%,且该模型对产品选择性也具有良好的预测能力。
According to the 9-lumped kinetic model and the total kinetic model as well as the mechanism of the F-T synthesis wax hydrocracking process,a 5-lumped kinetic model was established.On the basis of the concept of isomerization factor,the experimental results combined with isomerization reaction simulation and the introduction of cracking probability function,the original 9-lumped kinetic model cracking assumption was improved.Cracking probability function made the model more close to the actual hydrocracking process.There were seven reactions in the 5-lumped reaction kinetic model.Two kinds of kinetic models were compared by using the experimental results over the catalyst consisting of platinum（0.6%,mass）supported on amorphous silica alumina modified with H-β.The average relative error between the 5-lumped kinetic model calculations and experimental values was 3.95%.When conversion was higher than 90%,average relative error was below 0.8%.From the comparison,product selectivity could be well predicted by the 5-lumped model.
