摘要 TiO2·Al2O3多孔复合氧化物是新型的催化剂载体材料,因其在加氢精制工艺上能够显著增加催化剂的脱硫、脱氮活性而逐渐受到重视。本文综述了国内外关于TiO2·Al2O3多孔材料的制备方法,分析了制备方法对材料的比表面积、孔结构、表面酸性等载体性能影响的一般规律。通过对国内外研究者的TiO2.Al2O3合成方法的综合评述,指出了有待发展提高的方向。 Porous composite oxide of TiO2·Al2O3 is a new type of catalyst support,which has attract-ed increasing attention due to its capability to improve catalytic activity for hydrodesulfurization（HDS）and hydrodenitrogenation（HDN）of hydrotreating catalyst.This paper reviews the studies on the synthesis of porous TiO2·Al2O3 and analyzes influence factors of catalyst support properties,such as textural property and surface acidity etc,in the synthesis process.
