【摘要】 用浸渍法制备了铂锡铥和铂锡镜催化剂。在脉冲微型反应器一色谱仪联合装置上,考察了环已烷、甲基环戊烷和正庚烷在上述催化剂上的芳构化反应。结果表明:稀土铥或镜改变了负载型铂锡催化剂的催化性能,其改性作用不尽相同,即使同一稀土元素也随其含量不同而异。更多还原

【Abstract】 Pt--Sn--Tm and Pt--Sn--Yb catalysts were prepared byimpregnation. The aromatization of cyclohexane, methylcyclopentane and n--heptane on the catalysts was investigatedwith a pules microcatalytic reactor--gas chromatography device. Theresults showed that the properties of catalysts had changedwith both different rare earth and contents of the same element.更多还原
