• 中文摘要： 茲由機械混合法製備不同Mo含量之各 MoO/sub 3//Al/sub 2/O/sub 3/觸媒,這些觸媒接著以X-光繞射(XRD)、程溫還原(TPR)、測 BET表面積、吸附二氧化碳、異丙醇氧化以及 thiophene脫硫等方法鑑定之,結果顯示Mo以分散形式存在的最大承載量為7.17wt% Mo,且Mo在觸媒表面有許多結構存在,這些結構之相對含量隨Mo含量之變化而變化。各項鑑定之結果都與由浸漬法觸媒所得之結果比較,比較的結果顯示由不同方法所製備之觸媒其性質相似,不同點在於它們對各項鑑定之反應在量上稍有不同。
• 英文摘要： MoO/sub 3//Al/sub 2/O/sub 3/ of various molybdena loadings were prepared by a mechanical mixing method. The catalysts thus prepared were subjected to characterizations of X-ray diffraction (XRD), temperature programmed reduction(TPR), BET surface measurement, CO/sub 2/ adsorption, isopropanol partial oxidation and thiophene desulfurization. The results show that the maximum dispersed Mo loading is about 7.17wt% Mo. The relative amounts of various surface species change with Mo loading. The results of various characterizations were compared with those of corresponding catalysts prepared by impregnation. The comparison showed that even though the nature of the catalyst is independent of the method, there is still some quantitative difference in responding to the above mentioned characterizations.
