催化裂化汽油改质降烯烃并多产丙烯的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 reformulation for reducing olefin and enhancing propene production. Lumps were defined not only by their boiling range but also by their chemical compositions. Rate constants, frequent factors and activation energies parameters were estimated according to the experimental data. The proposed model could not only predict the yields successfully, but also provide more information about the chemical compositions of naphtha; which is useful for any attempts to reduce the olefin content in FCC naphtha and to enhance the propene production.
