| 摘 要： | 过渡金属离子的交换往往能对沸石的酸性和微孔结构起到调节作用［１］，同时金属元素还会带来自身特有的催化功能，使之成为优良的多功能催化剂［２］．在无氧条件下的芳构化反应中，甲烷的活化被认为是按“多相酸助异裂活化”方式进行的，即在Ｈ－ＺＳＭ－５的强酸中心作...

| Abstract: | The catalytic performance of methane aromatization in the absence of oxygen over Mo based catalysts using the fourth period transitional metal ions exchanged HZSM 5 as the supports have been studied in the paper. Moreover, the activity of the catalysts was correlated with the amount of deposited carbon over the catalysts after reaction. By introduction of transitional metal ions to the exchanged sites of H ZSM 5, the metal ions acted as the promoters and controlled the production of deposited carbon, so enhanced activity and stability of the catalysts to some extent. Among the ions exchanged MoO 3/MHZSM 5 catalysts, those exchanged with Cu 2+ , Fe 3+ , VO 2+ and Mn 2+ have a relatively high activity and stability . |
