Abstract

Selective hydrogenation of fluid catalytic cracking (FCC) gasoline is an effective method to reduce the sulfur and olefin contents in it for clean gasoline. Based on the characteristics of the DSO-M and M-DSO processes for the hydro-upgrading of heavy fraction of FCC gasoline hydro-upgrading and the contribution of different hydrocarbons to the octane number, two five-lump reaction networks for M upgrading stage and DSO hydro-desulfurization stage respectively were constructed. According to the experimental data from a micro-tubular fixed bed reactor for FCC gasoline hydro-upgrading, the kinetic parameters of the 5-lump models for M and DSO stages were worked out respectively by Runge–Kutta algorithm and genetic algorithm. The kinetic analysis demonstrates that M-DSO process is better than DSO-M process. Moreover, verification indicates that the models established have good reliability and extrapolation.

催化裂化汽油加氢的M-DSO过程集总动力学模型

摘要

流化催化裂化（FCC）汽油的选择性加氢是降低清洁汽油中硫和烯烃含量的有效方法。根据FCC汽油加氢重质馏分的DSO-M和M-DSO工艺特征，以及不同烃对辛烷值的贡献，两个五重反应网络分别用于M提质阶段和加氢阶段。分别建立了DSO加氢脱硫段。根据微管固定床反应器催化裂化汽油加氢反应的实验数据，分别通过Runge-Kutta算法和遗传算法计算出M和DSO阶段的5团模型动力学参数。动力学分析表明，M-DSO工艺优于DSO-M工艺。而且，
