本文以环已烷和甲基环戊烷在铂载在Al2O3 ,SiO2 ,Si-Al等不同担体的催化剂上进行的异构反应为探针 ,讨论催化剂的担体性质对C6 环烷烃异构反应的影响。结果表明 :对环已烷、甲基环戊烷的异构反应 ,担体对其异构反应的影响不大 ,主要是取决于催化剂的活性组分 ,因此对催化剂的调变主要应从活性组分的性质方面进行调变 In this paper, the isomerization of cyclohexane and methylcyclopentane on the catalysts supported on different supports such as Al 2 O 3, SiO 2 and Si-Al was investigated as a probe to discuss the isomerization of C6 cycloalkanes influences. The results showed that the isomerization reaction of cyclohexane and methylcyclopentane had little effect on the isomerization reaction of cyclohexane and methylcyclopentane, which mainly depended on the active component of the catalyst. Therefore, the modulation of the catalyst mainly consisted of the active component The nature of the change
