The catalytic process of ethylene oxychlorination can be split into two steps,uiz.ethylenechlorination with the reduction of cupric chloride and reoxidation of the cuprous chloride by hydrogen chloride and oxygen. The transient process of 1,2-dichloroethane formation was observed by selected ion chromatography using a mass spectrometer. While the reaction exhibited first-order kinetics in regard to the concentration of cupric chloride, the dependency on ethylene concentration was interpreted by a Wachi & Yousuke and Carrubba mechanism. Optimal performance was achieved by impregnating ea. 5 wt % of copper into y-alumina powder and 64% of the copper contained in the alumina powder contributed to the formation of 1,2-dichloroethane.this study, constant adverse reactions were calculated due to the experimental data obtained from Abadan Petrochemical Unit and the speed equation of Wachi was modified. The reaction occurs at three phases of bubble, cloud, and emulsion and by increasing temperature and input gas velocity and keeping all the other parameters constant in several steps, the substrate was investigated and the conversion of ethylene and gross value for each test were calculated. Thus, with the determination of kinetic and dynamic parameters, the proper mathematical model was chosen and using this model, the conversion percent of ethylene was calculated and its actual amount and the percentage of error were calculated and compared based on information obtained from Abadan Petrochem- ical reactor under different conditions
