加氢精制催化剂载体的研究进展

Recent Progress in Hydrorefining Catalyst Supports

综述了单组分氧化物、复合氧化物、碳材料、介孔材料和分子筛等载体在加氢精制催化剂方面的应用。单组分氧化物做载体时,TiO_2和ZrO_2载体比传统的γ-Al2O_3载体制得的催化剂活性高;复合氧化物载体主要包括含Al_2O_3的复合载体、含TiO_2的复合载体、含ZrO_2的复合载体和含ZnO的复合载体,其中TiO_2-Al_2O_3是研究最多的复合氧化物载体;活性炭负载的加氢催化剂有较高的加氢活性和较低的结焦倾向;介孔材料和分子筛载体由于具有大比表面积,是加氢催化剂载体的研究热点。

Applications of single component oxides, composite oxides, carbon materials, mesoporous materials and molecular sieves as supports of hydrorefining catalysts were reviewed. Catalysts supported on single oxides such as TiO2 and ZrO2 showed higher hydrorefining catalytic activities than these supported on traditional γ-Al2O3. Composite oxide supports containing Al2O3, TiO2, ZrO2 or ZnO were introduced respectively, among which TiO2-Al2O3 composite support was studied most widely. Catalysts supported on activated carbon were high in hydrogenation activity and low in coking. Due to their high specific surface areas, mesoporous and molecular sieve materials were paid increasing attention in the field of hydrorefining catalyst supports.
