中文摘要 | 以化學鍍法製備不等銅含量Cu/Al2O3之觸媒,探討其銅晶徑、銅含量及銅表面積對醇類脫氫反應活性的影響。以N2O為吸附質之真空熱控系統分析及XRD圖譜,分別得知銅晶徑之大小。並於連續式固定床微反應系統,以程溫還原的方法,探討銅觸媒和氧化鋁載體間之相互作用。實驗結果得知:醇類及脫氫活性略受銅分散度的影響,而脫水反應則受有效酸度所左右。 |
英文摘要 | Several Cu/Al2O3 catalysts of different copper loadings were prepared by electroless copper plating method. Copper crystallite diameter, copper loading and copper surface area are used to realization the effected on the dehydrogenation alocohols. Copper crystallite diameter are obtained by XRD and a self-established vacuum system via the chemisorption of N2O. A continuous fixed-bed microreactor system was used to study the metal interaction relationship between the catalysts and the alumina support through the temperature-programmed reduction. The dehydrogenation activity slight depends on copper dispersion and the dehydration activity clearly influences on the effective acid sites of the catalysts. |
