A kind of catalyst used for hydrogenation of distilled oil fraction and preparation method thereof, described catalyst contains a kind of carrier and at least a group VIII and at least a metal oxide that is selected from group vib of being selected from that loads on this carrier, wherein, described carrier is composited by aluminium oxide and modification mesopore molecular sieve Al-SBA-15, thereby described modification mesopore molecular sieve is introduced trivalent aluminium ion and has been introduced acidic site in the SBA-15 skeleton, therefore is suitable for the liquid-phase catalysis reaction that has big molecule to participate in; Simultaneously, in aluminum ions introducing process, also increase the pore wall thickness of SBA-15, improved the hydrothermal stability of carrier.Hydrogenation catalyst of the present invention has acid amount appropriateness, metal dispersity is higher and the advantage of good hydrothermal stability. |
