Beschreibung
Zusammenfassung:	The supported hydrogenating noble metal carrier consists of mainly spherical carrier material and noble metal as active component, and features that the spherical carrier material contains alumina in 50-99 wt% and magnetic grain in 1-50 wt%. The magnetic grain consists of SiO2 coating layer and kernel of Fe3O4, Fe and/or gamm-Fe2O3 in the weight ratio of 0.05-6 to 1. The noble metal as active component is one or several selected from Pt, Pd, Ru and Rh. 本发明公开了一种负载贵金属的加氢催化剂，主要由球形载体材料和贵金属活性组分组成，其特征在于所说的球形载体材料中含有50～99重％的氧化铝和1～50重％的磁性颗粒，其中所说的磁性颗粒由重量比为0.05～6∶1的SiO#-[2]包覆层和选自Fe#-[3]O#-[4]、Fe和γ-Fe#-[2]O#-[3]中的一种或几种内核组成，所说的贵金属活性组分选自铂、钯、钌、铑中的一种或几种。
