A hydrocracking catalyst comprises acidic silica-alumina, optional alumina, catalytically effective amount of at least one of VIII metals and at least one of VIB metals, and organic additives. The organic additive is one or more compounds selected from oxygen-containing or nitrogen-containing organic compounds and the mole ratio of the organic additives to the VIII metals is from 0.01 to 10. The preparing method of the catalyst and the application thereof in hydrocracking of a hydrocarbon are also disclosed. The hydrocracking catalyst of the present invention has higher hydrogenating and ring-opening activity than that of the prior hydrocracking catalysts.

L'invention concerne un catalyseur pour hydrocraquage, comprenant de l'alumine-silice acide, éventuellement de l'alumine, une quantité efficace au point de vue catalytique d'au moins un métal VIII et d'au moins un métal VIB, et des additifs organiques. Les additifs organiques sont constitués d'un ou de plusieurs composé(s) choisi(s) parmi des composés organiques contenant de l'oxygène ou de l'azote, et le rapport molaire entre les additifs organiques et les métaux VIII est compris entre 0,01 et 10. L'invention concerne également une méthode de préparation du catalyseur et son application à l'hydrocraquage d'un hydrocarbure. Le catalyseur pour hydrocraquage selon la présente invention présente une activité d'hydrogénation et d'ouverture de cycles plus importante que les catalyseurs pour hydrocraquage déjà connus.
