Abstract Based on the group composition and properties of fluid catalytic cracking (FCC) gasoline and behavior of FCC gasoline hydroisomerization and aromatization, a seven-lump kinetic model was developed. In this model, the reaction system was lumped into normal paraffin, isoparaffin, linear olefin, branched olefin, cyclo-olefin, naphthene and aromatics. The kinetic parameters were estimated by the Levenberg-Marquardt algorithm and verified using experimental data. The results showed that this model could predict the group composition of the hydro-upgraded FCC gasoline, with the relative error less than 10% and provided a basis for the optimization, design and operation of the FCC gasoline hydroisomerization and aromatization.
