| 摘 要： | 本文研究了Mo/纳米MCM-49催化剂上甲烷无氧芳构化反应.考察了反应温度对甲烷转化率及苯的收率的影响.反应温度在973 K,催化剂取得良好催化活性,甲烷转化率为11～12%,生成苯的选择性为80%～90%.本文还对催化剂稳定性、积碳行为以及再生条件进行了考察.研究表明Mo/纳米MCM-49催化剂稳定性远远超过Mo/ZSM-5催化剂稳定性.通过直接焙烧和添加定量的MoO3活性组分的方法可大幅度延长催化剂的寿命.

| Abstract: | The aromatizing reaction of methane without oxygen on Mo/nm. MCM-49 catalyst is studied in this paper, and the influences of reaction temperature on conversion rate of methane and the production rate of benzene are also investigated. The activity of catalyst is good at 973K that conversion rate of methane is 11%-12%, and the selectivity of benzene is 80%-90%. The article details the research of the stability of catalyst, carbon deposition and regeneration conditions. The results indicate the stability of Mo/Nm. MCM-49 catalyst is higher than Mo/ZSM-5 catalyst. The life of catalyst can be prolonged by adding the quantitative active component of MoO 3 and baking directly. |
