按照集总理论划分原则,在前人研究基础上,改进了13集总催化重整反应模型。改进后的模型将重整物料分为C6、C7和C8~+,每一个碳数的化合物又划分为正构烷烃、异构烷烃、环烷烃和芳烃4个集总,裂化产物C5~-作为一个集总。集总组分之间主要发生加氢裂化、烷烃异构化、烷烃环化和环烃芳化反应,根据各个反应动力学模型和重整反应器数学模型编制了模拟计算软件。该软件较简便准确地预测了重整产物组成、重整反应器温降和汽油辛烷值。
According to the principle of division of lumped theory, based on the previous studies, we improved the 13-lumped catalytic reforming reaction model. The improved model divides the reformate into C6, C7 and C8 ~ +. Each compound of carbon number is divided into four lumped products of n-paraffins, isoparaffins, cycloalkanes and aromatics. C5 ~ A lumped. Hydrocracking, paraffin isomerization, paraffinic cyclization and paraffins aromatics reactions occur mainly between the lumped components. According to the reaction kinetic model and the mathematical model of the reforming reactor, the simulation calculation software was developed. The software is simple and accurate prediction of the reformate composition, reforming reactor temperature drop and gasoline octane number.
