• 中文摘要： 在含三氧化二鐵及第一週期過度金屬氧化物之二元氧化物觸媒上進行環己醇之非氣化性脫氫反應。正丁胺與醋酸之升溫規劃脫附( TPD)分別用以測定觸媒之酸鹼性質,環己醇之脫氫反應則分別在脈衝及流動稀釋反應器內進行。實驗結果顯示,環己酮產率與二元氧化物表面酸鹼性質之間有密切關係存在。觸媒上含浸氧化鉀或硼酸時環己酮之產率減低,表示脫氫反應之活性基係由酸性點與鹼性點所組成。脫水副反應發生於弱酸點上,所生環己烯之量隨酸量之增加而增多。
• 英文摘要： The binary oxides containing Fe/sub 2/O/sub 3/ and another first period transition metal oxide were studied as catalysts for nonoxidative dehydrogenation of cyclohexanol. The acidity and basicity of the catalysts were measured by temperature-programmed desorption (TPD) of n-butylamine and acetic acid, respectively. The dehydrogenation of cyclohexanol was carried out by using both pulse and continuous dilute flow reactors. A good correlation was found between the yield of cyclohexanone and the surface acid-base properties of binary oxides. The yield of cyclohexanone was decreased by doping either K/sub 2/O or H/sub 3/BO/sub 3/ to the catalyst, indicating that the active sites for dehydrogenation reaction consist of both acid and basic sites. With regard to side dehydration reaction, it seemed that cyclohexene took place on the weaker acidic sites, the more the acidity the larger the extent.
