Presented is a selective hydrogenation catalyst and a method of making the catalyst. The catalyst comprises a carrier containing bi-metallic nanoparticles. The nanoparticles comprise a silver component and a palladium component. The catalyst is made by incorporating an aqueous dispersion of the bi-metallic nanoparticles onto a catalyst carrier followed by drying and calcining the carrier having incorporated therein the dispersion. The catalyst is used in the selective hydrogenation of highly unsaturated hydrocarbons contained olefin product streams. L'invention concerne un catalyseur d'hydrogénation sélective et un procédé de fabrication du catalyseur. Le catalyseur comprend un support contenant des nanoparticules bimétalliques. Les nanoparticules comprennent un composant d'argent et un composant de palladium. Le catalyseur est fabriqué par incorporation d'une dispersion aqueuse des nanoparticules bimétalliques sur un support de catalyseur suivi par le séchage et la calcination du support dans lequel est incorporée la dispersion. Le catalyseur est utilisé dans l'hydrogénation sélective d'hydrocarbures hautement insaturés contenus dans des flux de produits oléfiniques.
