| 摘 要： | 研究了丙烷在不同ＳｉＯ２／Ａｌ２Ｏ３比值的ＨＺＳＭ５和Ｇａ改性ＨＺＳＭ５催化剂上的芳构化转化，为探讨氢转移反应的能力，也考察了在丙烷中添加少量氢对芳构化转化的影响。结果表明，随ＨＺＳＭ５分子筛ＳｉＯ２／Ａｌ２Ｏ３比值的减小，氢转移反应程度增大；在分子筛中引入Ｇａ，氢转移反应能力增大。最后提出了有Ｇａ参与的反应机理。

| Abstract: | Propane aromatization over HZSM 5 zeolites with different SiO 2/Al 2O 3 ratios and Ga modified HZSM 5 catalysts were studied, and the influence of the addition of a small amount of H 2 on propane conversion was also tested in order to investigate the hydrogen transfer reactions. The results showed that the hydrogen transfer ability increased with the decrease of zeolite SiO 2/Al 2O 3 ratio, and the introduction of Ga into the zeolite enhanced the hydrogen transfer ability. A possible mechanism is also proposed. |
