The aromatization reaction of FCC gasoline has been studied by using three FCC gasoline (Shenghua, Lanlian, and Fushun) and LBO-A as catalyst, and the nine lumped kinetics models network have been put up forward on the basis of lumped theory and the aromatization reaction mechanism. In the network the aromatization reaction species were firstly lumped into n-paraffins, i-paraffins, olefins, aromatics, coke, C-= (4), C-0 (4), C-= (2-3), and H-2 + C-0 (1-3). The mathematical model forecasts the product yield with the reaction temperature and Weight Hourly Space Velocity and catalyst to oil and the reaction temperature of the different FCC gasoline, respectively. The results from experimental data are in accordance with the quantitative analytical conclusions drawn from the calculated data.
