    Title: 硫酸鈰內所含硫氧化物的結構與活性之研究
    Authors: 張鈞傑
    Keywords: 硫酸鈰

    Abstract: 大部分的空氣污染源如:NOX、SOX、CFC 等等,均來自於汽機車汽油燃燒所造成。然而目前較為重要的是利用觸媒來解決此項問題。在本篇論文中,旨在探討硫酸鈰在高溫的環境下,其中硫酸鈰的硫氧化物之結構與活性有何變化。已經知道氧化鈰常被用在三向觸媒(TWC¸Three Way Catalyst) (1,2) 和流體催化裂解( Fluidized catalytic cracking , FCC) (3)中。但氧化鈰超過400 oC高溫時的殘餘物並沒有其研究價值,只有硫酸鈰加熱至650 oC時還算穩定。但加熱至720 oC時,硫酸鈰內的硫氧化物結構則會開始產生變化,因而對其內所含硫氧化物的分子結構反應特性做進一步的測試與研究。
