• 中文摘要： 機械混合法在此被用來製備氧化矽承載之氧化鉬觸媒。以此法製備時,首先將氧化鉬與氧化矽混合,繼之以高溫燒,經燒後氧化鉬之結晶即解離並分散於氧化矽之表面形成眾多的活性點。為了能了解此法與傳統浸漬法之異同,本研究中之觸媒皆分別以兩種方法製備,並改變觸媒中之鉬含量以資比較。觸媒之鑑定採用X-光繞射、程溫還原及異丙醇之轉化反應為之。
• 英文摘要： A novel method, called the mechanical mixing method, was adopted for the preparation of MoO/sub 3/SiO/sub 2/ catalysts. This method involves a direct mixing and calcination of molybdena and silica powders. After calcination, molybdena crystals are dispersed onto a silica surface and form numerous active sites. To compare this method with the conventional method of impregnation, catalysts were also prepared by the later. In each method, the molybdena content was changed. The catalysts were characterized by X-ray diffraction (XRD), temperature programmed reduction (TPR), and a reaction.
