Abstract:

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.

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。
