An advanced hydrogenation catalyst was designed based on the good properties of encapsulated noble metal catalysts,which could be applied in the shape selectivity and hydrogen spillover reactions.Pt,sodalite zeolites and Pt(NH₃)₄Cl₂ were selected as the active components,carriers and metal precursors,respectively.Pt/SOD zeolites encapsulated with different amounts of Pt were hydrothermal synthesized.Then benzene hydrogenation reaction was used as probe reaction to test the catalytic activity of the samples.XRD,SEM,TEM and H₂-TPD were used to characterized the catalysts.The results showed that all Pt/SOD samples had good catalytic activity and excellent hydrogen spillover effect with spillover hydrogen acceptor HZSM-5.When the dosage of Pt(NH₃)₄Cl₂ was 0.063 6 g((Pt(NH₃)₄Cl₂):(Si-Al gel)=0.030 g/g),the Pt/SOD sample obtained showed the highest catalytic activity for benzene hydrogenation and the benzene conversion was 54.38%.
