Abstract

Abstract

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%.
