第Ⅰ,Ⅱ报结果指出,氧化态锡对Pt/Al_2O_3具有助催化作用。本文通过对氧化脱氢过程类比分析,提出具有可变价态元素氧化物可替代Pt-Sn/Al_2O_3催化剂中氧化态锡组分,而与金属铂组分构成一系列具有良好催化性能的负载型双组分催化剂。对Al_2O_3负载的Pt-Ti,Pt-V,Pt-Cr,Pt-Mn及Pt-Fe催化剂评价结果表明,催化剂性能均随氧化态组分(Ti,V,Cr,Mn,Fe等)载量增加而逐步改善。
The results of the first and the second reported that the oxidation of tin on the Pt / Al_2O_3 has a catalytic role. Based on the analogy analysis of the oxidative dehydrogenation process, the article proposed that a variable-value elemental oxide could replace the tin oxide component in the Pt-Sn / Al 2 O 3 catalyst and form a series of supported bis Component catalyst. The evaluation results of Pt-Ti, Pt-V, Pt-Cr, Pt-Mn and Pt-Fe catalysts supported on Al 2 O 3 show that the catalyst performance varies with the loadings of the oxidation states (Ti, V, Cr, Mn, Fe, Increase and gradually improve.
