铂-氟氢酸-氧化铝催化剂具有两种主要的活性中心;一种是由铂产生的脱氢中心,一种是由氟氢酸产生的异构化中心.甲基环己烷、甲基环戊烷、正庚烷在铂-氟氢酸-氧化铝催化剂上的主要反应结果符合于 Mills-Heinemann 提出的反应机理.催化剂的平均孔径随氟氢酸的含量增加而变大,孔径变大可能是正庚烷的加氢裂化反应随氟氢酸含量增加而显著加速的原因. Platinum-hydrofluoric acid-alumina catalysts have two major active sites; one is the dehydrogenation center from platinum and the other isomerization from hydrofluoric acid. Methylcyclohexane, methyl The main reaction results of cyclopentane and n-heptane on platinum-hydrofluoric acid-alumina catalyst are in accordance with the reaction mechanism proposed by Mills-Heinemann.The average pore size of catalyst increases with the increase of hydrofluoric acid content, This may be the reason that the hydrocracking reaction of n-heptane accelerates significantly with increasing hydrofluoric acid content.
