[en] The temporal evolution of the activity and selectivity of a 1.9%Pd-3.7%Ag/SiO2 catalyst during selective hydrodechlorination of 1,2-dichloroethane into ethylene is examined. A comparison between the physico-chemical properties of the fresh catalyst and of the deactivated one suggests a deactivation mechanism by poisoning or coking of Ag sites at the surface of the active Pd-Ag particles. A regeneration treatment is proposed which allows to restore the initial properties of the fresh catalyst.
