A catalyst composition and process for preparing such catalyst composition which can be useful in contacting a hydrocarbon-containing fluid which contains a highly unsaturated hydrocarbon such as 1,3-butadiene, in the presence of hydrogen, with such catalyst composition in a hydrogenation zone under a hydrogenation condition effective to hydrogenate such highly unsaturated hydrocarbon to a less unsaturated hydrocarbon such as n-butene is disclosed. Such process for preparing a catalyst composition includes (1) combining a zeolite, a Group VIB metal, and an inorganic support to form a modified zeolite; (2) calcining such modified zeolite under a calcining condition to produce a calcined, modified zeolite; and (3) contacting such calcined, modified zeolite with a carburizing agent under a carburizing condition to provide such catalyst composition.

L'invention concerne une composition catalytique et un procédé pour préparer cette composition, que l'on peut mettre en contact avec un fluide hydrocarboné, qui contient un hydrocarbure fortement insaturé tel que 1,3-butadiène, en présence de l'hydrogène et dans une zone d'hydrogénation dans des conditions d'hydrogénation efficaces pour hydrogéner cet hydrocarbure fortement insaturé en le transformant en un hydrocarbure moins saturé tel que n-butène. Ce procédé pour préparer une composition catalytique consiste en ce qui suit: (1) combiner une zéolite, un métal du groupe VIB et un support inorganique de manière à former une zéolite modifiée; (2) calciner cette zéolite modifiée dans des conditions de calcination pour produire une zéolite calcinée modifiée; et (3) mettre cette zéolite calcinée modifiée en contact avec un agent de carburation dans des conditions de carburation pour obtenir la composition catalytique de l'invention.
