1. a catalyst used for hydrogenation of distilled oil fraction, comprise carrier and load at least one on the carrier and be selected from the metal oxide that group VIII and at least one are selected from group vib, it is characterized in that:

  • described carrier is composited by aluminium oxide and mesoporous molecular sieve SBA-15;

    The method of the catalyst used for hydrogenation of distilled oil fraction described in preparation, comprises the following stepsI. aluminium oxide precursor and silicon source material Homogeneous phase mixing are obtained a kind of paste;

    Ii. at maintaining the temperature at 35-45 DEG C, first by triblock copolymer EO 20pO 20eO 20(polyethylene glycol-glycerine-polyethylene glycol) mixes with dilute acid soln as template, obtains jelly after stirring, adds in described jelly by the described paste obtained in step I, obtains a kind of mixture after constantly stirring;

    Iii. the described mixture hydrothermal crystallizing will obtained in step I i, the product obtained after filtration, washing, obtain compound SBA-15/ aluminium oxide after dry and roasting;

    Iv. carry out at least single-steeping with the maceration extract being selected from group VIII and at least one containing at least one and being selected from the metal of group vib to described compound SBA-15/ aluminium oxide, namely product drying, roasting obtain described catalyst used for hydrogenation of distilled oil fraction.
