KINETIC STUDY ON THE OXYCHLORINATION OF BENZENE.

Article abstract of DOI:10.1246/bcsj.56.909

Gas-phase benzene oxychlorination was carried out over a CuCl//2-CeCl//3/Al//2O//3 catalyst. A kinetic model is proposed which permits us to obtain a rate equation capable of reproducing experimental results. The presence of cerium in the catalyst increases the reaction rate and maintains the conversion level for a long time. It seems that this element facilitates copper reoxidation by making the total rate independent of the partial pressure of oxygen and stabilizes the active phase of the catalyst.
