摘要: 国外,对银催化甲醇氧化脱氢制甲醛的反应动力学曾进行了研究,但对乙醇催化制乙醛的反应动力学,未见到研究报导。本文用自己组装的微反-色谱-DTA联合装置进行了乙醇催化氧化脱氢反应动力学的研究。

Abstract: The combined device of microreactor-gas chromatography-DTAis designed to study the catalytic reaction kinetics. With the device the data of reaction kinetics of ethanol over electrolytic silver catalysts have been measured. The conversion of cthanol is<5%. The oxidative dehydrogenation of ethanol is zero order to oxygen and 1.08 to ethanol while no side reaction take place, and the activation energy is 18.5 kcal/mol.
