| 摘 要： | 以原位生长法制得的Y分子筛/TiO2-SiO2 氧化物（CTS）为载体，以Ni、W为活性金属组分，采用载体表面浸渍磷（P）和在金属组分浸渍液中加入磷（P）的共浸渍方法制备P改性NiW/CTS催化剂，研究了不同P改性方法对催化剂理化性质及加氢性能的影响。实验结果表明，P改性使NiW/CTS催化剂总酸量下降，但表面浸渍P改性使催化剂L酸中心数量下降，而共浸渍P改性使催化剂L酸中心数量增加；P的引入削弱载体与金属间的相互作用，提高金属组分在载体表面的分散性，其中共浸渍P改性法更有利于促使高加氢活性前躯体的形成。因此，共浸渍P改性的催化剂对脱残渣油具有更好的加氢脱硫、脱氮和芳烃饱和性能。

| Abstract: | Heavy oil hydrotreating catalysts NiW/CTS were prepared by iso-volumetric impregnation method,where the catalyst support(CTS) was obtained from in-situ growth of TiO2-SiO2 oxides covering on the particles of Y zeolites.NiW/CTS catalysts were then modified by surface impregnation of phosphoric acid or co-impregnation of phosphoric acid with metal precursors.The effect of phosphoric acid modification on the physic-chemical properties and hydrotreating performance of the NiW/CTS catalysts were investigated.The... |
