| 摘 要： | 研究了在Li2SO4/MgO催化剂中引入少量Sm2O3和La2O3对甲烷氧化偶联反应的影响，并考察了催化剂的稳定性能。结果发现,在Li2SO4/MgO催化剂中引入少量Sm2O3可以提高催化剂活性和生成C2烃的选择性，而加入少量La2O3会降低甲烷转化率。经500h活性考察，Li2SO4/Sm2O3.MgO催化剂表现出良好的稳定性，具有深入研究的价值。

Promoter action of Sm2O3 and La2O3 on oxidative coupling reaction of methane |

| Abstract: | The effect of Sm2O3 and La2O3 on Li2SO4／ＭgO catalyst for oxidative coupling reaction of methane has been studied,while the stability of catalyst has also been tested.The results show that the activity of catalyst and the selectivity of C2 hydrocarbons can be improved when a little Sm2O3 adds to Li2SO4／ＭgO catalyst,but the conversion of methane will be reduced when a little La2O3 adds to.The Li2SO4／Sm2O3-ＭgO catalyst showed good stability during 500h countinous activity test,so it i s worth being studied profoundly. |
