Abstract: In this paper, the reaction activity of impregnated microspheroidal CuCl2/Al2O3 catalyst using in oxygen based ethylene oxychlorination to prepare ethylene dichloride was studied. XRD, TPR and pulse reaction technique proved that the impregnated catalyst has identical active phase of CuCl2 with commercial coprecipitated catalyst,though the copper present in the later at first is in the form of Cu2(OH)3Cl, but it changes into CuCl2 by HCl which is presented in the reacting gas as the oxychlorina-tion takes place. The copper content and its state of distribution on the surface of γ-Al2O3 car-rier appear important in the activity development of the catalyst. They also show a serious influence on the fluidity in fluidized bed reaction. The impregnated catalyst is simple to prepare and its cost is low. Catalyst with 9%(wt) copper content may be used instead of the coprecipitated catalyst having 13% (wt) of copper.
