摘 要: | 本文采用TPD、IR技术和微反装置以及乙烷氧化脱氢反应表征了 Li/mgo(2m mol/mol)催化剂,将其结果与Mgo(H_2O)比较,发现;Li/mgo(2m mol/mol)的催化性能更优于Mgo(H_2O)的催化性能.催化氧化脱氧亦与催化剂表面酸、碱中心协同作用有关,温度、原料配比、反应时间等对协同作用存在较大影响.

Abstract: | In this paper, the oxydehydrogenation of ethane over Li/Mgo(2m mol/mol)catalyst have been invetigated by mean of TPD, IR. The result shows:The surface on catalyst of Li/Mgo (2m mol/mol) there ovre three basicity centres and two acidity centres. All function are in advance of Mgo (H2O) catalyst. |
