A six-lump kinetic model was developed to predict the yields of the target products i-paraffin and aromatics in the FCC gasoline hydro-upgrading process aiming at olefin reduction and octane preservation. The experimental data obtained in a fixed bed reactor were used to estimate the eight kinetic constants and the corresponding activation energies in the model using the Marquardt algorithm. The model testing results revealed that the model predictions were in good agreement with the experimental results, indicating the excellent reliability of the model. Furthermore, the model could be extended to different feedstocks and wide operating conditions. The optimal operating conditions for producing Euro IV clean gasoline with the desired olefin and aromatics contents were determined on the basis of the predicted product yields and verified by the experimental results.
