【摘要】 由于石油资源的日见枯竭 ,天然气在化工原料中的地位日益突出。对天然气的主要成分甲烷、氧化偶联 (OCM)制备乙烯的催化剂—— Li Cl/Mn O2 - H3 BO3 进行了系统研究并探讨了其组分及外界反应条件对该催化剂性能的影响 ,发现了可能的活性组分 :立方晶型的 Li4 B7O12 Cl。更多还原

【Abstract】 Because of the rising price and the exhaustion of petroleum, the role of nature gas as raw material has become more and more important in chemical industry. The catalysts——LiCl/MnO₂-H₃BO₃ for oxidative coupling of methane （OCM） have been investigated. The results show the catalysts possess high activity and selectivity. Furthermore, the influence of the components of the catalysts and the reactive conditions were explored and find the possible active component——cubic Li₄B₇O 12Cl.更多还原
