| 摘 要： | 采用共沉淀法制备镧改性的Ni/-γAl2O3催化剂催化甲烷部分氧化反应,表现出较高的和活性和稳定性。BET、TPR和XRD表征说明镧的加入提高了催化剂的比表面积,降低了催化剂活性组分还原温度,提高载体稳定性。最后提出一种在La-Ni/-γAl2O3催化剂上甲烷部分氧化反应的机理。

| Abstract: | La modified Ni/γ-Al_2O_3 catalysts prepared by co-deposition method showed high activity and stability for partial oxidation of methane.BET,TPR and XRD studies proved that the addition of La enhanced the surface areas of catalysts,reduced reduction temperature of active component and improved the stability of supports.A new mechanism for the partial oxidation of methane over La-Ni/γ-Al_2O_3 was proposed. |
