• 中文摘要： 本文之目的在探討乙醇於銅-鉻觸媒上脫氫轉化為乙醛之反應動力學。研究之溫度範圍介於210-290.degree.C間,時間因子介於 0.5-8.0g-cat-hr/g mole之間。本文利用微分方法證實脫氫反應時,乙醇於銅-鉻觸媒上之吸附為反應的控制步驟。根據此一結果所推導之動力式,可準確地預估實驗結果。
• 英文摘要： The catalytic dehydrogenation of ethanol into acetaldehyde over copper-chromia catalyst in a fixed bed reactor in the temperature range 210-290.degree.C at atmospheric pressure and time factor values ranging from 0.5 to 8.0g-cat-hr/mole is investigated. By the differentiating method it is found that the dehydrogenation appears to take place at a single site on the catalyst surface in which product hydrogen gets adsorbed and where the adsorption of ethanol is controlling the rate of reaction. Based on this mechanism, a rate equation is derived which is able to predict the experimental data quite well.
