The present invention provides a kind of hydrocracking catalyst, the catalyst includes a compound support consisting of zeolite molecular sieve and alumina, at least a metal component of VIII group, at least a metal component of VIB group, and an organic additive. The said organic compound is selected from the group of oxygen containing or nitrogen containing organic additive. Based on the weight of the catalyst, the content of the zeolite molecular sieve is 3-60 w%, the content of the alumina is 10-80 w%, the content of the organic additive is 0.1-40 w%. Calculated as the oxide and based on the weight of the catalyst, the content of the metal component of VIII group is 1-15 w%, the content of the metal component of VIB group is 5-40 w%. The present invention also relates to the preparation method of the said catalyst and its use in hydrocracking method of the hydrocarbon oil. Compared with the catalyst provided by the kown technology, the aromatics hydroconverting activity of the catalyst provided by the present invention has been improved notably.

L'invention concerne un catalyseur d'hydrocraquage qui comprend un support de composé formé d'un tamis moléculaire de zéolithe et d'alumine, d'au moins un composé métallique du groupe VIII, d'au moins un composé métallique du groupe VIB, et d'un additif organique. Le composé organique est sélectionné dans le groupe d'additifs organiques contenant de l'oxygène ou de l'azote. D'après le poids du catalyseur, la teneur en tamis moléculaire de zéolithe est de 3 à 60 % en poids, la teneur en alumine est de 10 à 80 % en poids, et la teneur en additif organique est de 0,1 à 40 % en poids. La teneur en composé métallique du groupe VIII est comprise entre 1 et 15 % en poids et la teneur en composé métallique du groupe VIB est comprise entre 5 et 40 % en poids. Valeurs exprimées en termes d'oxyde et d'après le poids du catalyseur. L'invention concerne également le procédé de préparation du catalyseur et son utilisation dans un procédé d'hydrocraquage d'hydrocarbures liquides. L'activité d'hydroconversion d'hydrocarbures aromatiques du catalyseur a été considérablement améliorée par rapport au catalyseur de l'art antérieur.
