The authors elaborated a detailed kinetic model of gasoline catalytic reforming that accounts variation of temperature and the reaction mixture mole number. Particular components of the reaction mixture are grouped according to the hydrocarbon class: aromatic hydrocarbons; five-membered naphthenes; six-membered naphthenes; isoparaffins; and normal paraffins. An industrial facility—a catalytic reforming unit L-35-11/300—workflow data were used as experimental data. The schematic diagram of a reactor section and reformate stabilization section was examined. The inverse kinetic problem was resolved and kinetic parameters of the main stages were calculated. For resolving the issue of catalytic reforming restrictions for commercial Euro 6 Standard petrol (benzene and aromatic hydrocarbons content), the authors proposed to define and resolve the task of multi criteria optimization of conditions which would simultaneously account several criteria based on the kinetic model. The optimality criteria are as follows: the yield and octane number of reformate, the octane number of the whole mixture, and content of benzene and aromatic hydrocarbons. Multi criteria optimization task resolution provided for defining the temperature mode in the reactor section, which allows one to lower the yield of benzene and aromatic hydrocarbons without any substantial reduction of octane number and increase in the reformate yield.

基于烃类动力学模型的汽油催化重整温度体系多指标优化

作者详细阐述了汽油催化重整的动力学模型,该模型考虑了温度和反应混合物摩尔数的变化。反应混合物的特定组分根据烃类分组:芳烃;五元环烷烃;六元环烷烃;异链烷烃;和普通石蜡。一个工业设施——催化重整装置 L-35-11/300——工作流程数据被用作实验数据。检查了反应器部分和重整产品稳定部分的示意图。解决了逆动力学问题并计算了主要阶段的动力学参数。为解决商用欧 6 标准汽油(苯和芳烃含量)的催化重整限制问题,作者提议定义和解决条件的多标准优化任务,该任务将同时考虑基于动力学模型的多个标准。优化标准如下:重整油的收率和辛烷值,整个混合物的辛烷值,苯和芳烃的含量。为定义反应器部分的温度模式提供了多标准优化任务解决方案,这允许降低苯和芳烃的产率,而不会显着降低辛烷值并增加重整产品的产率。整个混合物的辛烷值,以及苯和芳烃的含量。为定义反应器部分的温度模式提供了多标准优化任务解决方案,这允许降低苯和芳烃的产率,而不会显着降低辛烷值并增加重整产品的产率。整个混合物的辛烷值,以及苯和芳烃的含量。为定义反应器部分的温度模式提供了多标准优化任务解决方案,这允许降低苯和芳烃的产率,而不会显着降低辛烷值并增加重整产品的产率。
