| 摘 要： | 采用共沉淀浸渍法与沉淀-混合共沉淀浸渍法考察了不同制备方法以及不同稀土种类等不同制备条件下的S2O82-/Z rO2-S iO2类固体超强酸催化剂的催化活性.结果表明:沉淀-混合共沉淀浸渍法制备的催化剂活性远远大于共沉淀浸渍法制备的催化剂的活性.

| Abstract: | S_2O~(2-)_8/ZrO_2-SiO_2-like solid super acid catalysts were prepared by different preparing methods with different contents of rare earth oxides.Their activities were studied.The activities of catalysts prepared by mix-preciptation co-precipitation method were better than that prepered by the co-precipiation method. |

| Keywords: | solid super acid S_2O~(2-)_8/ZrO_2-SiO_2-Sm_2O_3 rare earth oxides activity |
