Abstract

Procédé pour l'hydrogénation sélective de constituants hydrocarbonés non saturés d'une charge de départ. Un catalyseur d'hydrogénation est d'abord prétraité par contact avec de l'ammoniac gazeux et ensuite mis en contact avec la charge de départ en présence d'hydrogène. Le procédé améliore la sélectivité d'hydrogénation du catalyseur, spécialement en réduisant au minimum l'hydrogénation indésirable de composés cycliques aromatiques.
