Abstract: 

In this paper, the deactivation of Pd-Ag/Al2O3 catalyst was investigated in acetylene selective hydrogenation. Therefore, the commercial catalyst performance was used in Godinez kinetic model. The deactivation kinetic constant of catalyst was calculated by appropriate deactivation order. The activity of main and side reaction was evaluated during time on stream.
If first or second deactivation kinetic order was assumed, the activity lost was 90% and 1%, respectively. Since lower order was increased deactivation, so the second order deactivation model was proposed. As well the effect of temperature on the activity lost by using this model in acetylene selective hydrogenation was investigated.
