*1.4. Research Outlook*

In this research, the reaction mechanism and kinetics of acetylene hydrogenation over the industrial Pd-Ag supported on α-Al2O<sup>3</sup> is investigated in a lab-scale packed bed reactor, considering GHSV (gas hourly space velocity), hydrogen to acetylene ratio, pressure, and temperature as independent variables. The full factorial design of experiment method based on the cubic pattern is used to determine the number and condition of experiments. The fresh and deactivated catalysts are characterized by XRD, BET, SEM, TEM and DTG analyses. In addition, a detail reaction network is proposed and correspond kinetic model is developed based on the Langmuir-Hinshelwood- Hougen-Watson approach. Then, the Tail-End hydrogenation reactors in Jam Petrochemical Complex are modeled based on the mass and energy balance equations at dynamic conditions. Based on the developed model and available plant data, a decay model is proposed to predict catalyst activity. Then, the accuracy of the model is proved at steady and dynamic conditions.
