载体对Pt催化甲基环己烷脱氢性能的影响

摘要

采用浸渍法制备了Al₂O₃、SiO₂、Y₂O₃及活性炭负载的0.2%(质量分数,下同)Pt催化剂。氮气吸附脱附、H₂-TPR、CO脉冲吸附对催化剂表征的结果表明,活性炭载体上活性组分的分散度最高,催化甲基环己烷(MCH)脱氢反应的结果表明,活性炭负载的Pt催化剂具有最高的催化活性。

Abstract：

In the present work, the Pt catalysts supported on Al₂O₃, SiO₂, Y₂O₃, and activated carbon (AC) with 0.2% Pt loading were prepared by impregnation method. N₂ adsorption-desorption, H₂-TPR and pulse CO chemisorption results showed that AC is beneficial to improve Pt dispersion. Moreover, the activity of the catalysts for dehydrogenation of methylcyclohexane(MCH) at 300 ℃ was investigated. The results suggest that Pt/AC catalyst exhibited high activities.
