Kinetic model of FCC naphtha olefin reformulation
催化裂化汽油改质反应动力学模型研究

A six-lump kinetic model was derived on the basis of FCC reaction mechanism to represent the FCC naphtha olefin reformulation.Lumps were defined not only by their boiling range but also by their chemical compositions.Rate constants,frequent factors and activation energies were estimated based on the experimental data.The proposed model could not only predict successfully the yields,but also provide more information of the chemical compositions of naphtha.The model is useful for the study of how to reduce the olefin content of FCC naphtha.
