• 中文摘要： 以浸漬法製備各種不同鉬含量之 MoO/sub 3//AlPO/sub 4/-5觸媒,這些觸媒的性質以X-光繞射及程溫還原來鑑定,活性則以異丙醇之部分氧化反應加以測試。X-光繞射的結果發現最大之非結晶鉬含量為3.4wt%, AlPO/sub 4/-5的結晶亦因鉬含量的增加而逐漸消失。以程溫還原可發現3個不同之氧化鉬結構,這些結構之間量的關係隨鉬含量而改變。活性之測試是在399K至419K之間進行,最大的轉化率在鉬含量為2wt%時發現,在低鉬含量時,生成丙酮之選擇性高。
• 英文摘要： MoO/sub 3//AlPO/sub 4/-5 catalysts of various molybdena loading were prepared by impregnation. The properties of these catalysts were examined by XRD and TPR, and their activities were tested by partial oxidation of isopropanol. The maximum non-crystalline loading of molybdenum was found to be 3.4 wt% by XRD. A loss of AlPO/sub 4/-5 crystallinity was also found by XRD to be in proportion to molybdenum loading. Three different molybdena species were found with TPR. The species change with molybdena loading. Catalyst activities were tested in temperatures between 399 and 419K. The maximum conversion was found at 2 wt% Mo. High acetone selectivity was obtained with low Mo loading.
