• 中文摘要： 本研究探討鋅添加對無電鍍銅觸媒在正丁醇脫氫反應的影響。銅含量為15%, 鋅則從1%到5%。實驗結果顯示鋅的添加有助於銅的分散同時也會增強銅與擔體之間的作用力, 如額外再添加鉀於銅鋅觸媒上, 將更加增強此效果。而鋅的添加也增加了銅觸媒在正丁醇脫氫反應上的活性, 額外添加鉀將使得活性變得更好。
• 英文摘要： The effect of Zn addition on the electroless copper catalyst in n-butanol dehydrogenation reaction was investigated. Copper loading on .gamma.-Al/sub 2/O/sub 3/ was fixed at 15% and Zn addition was varied from 1% to 5%. Experimental results show that Zn addition would increase copper dispersion and hence the copper surface area, and decrease copper crystallite size formed on the support. When extra potassium was added into the Zn-addition catalyst, further increase in copper surface area and decrease in crystallite size were observed. Zn addition would also cause the TPR carve slightly shifting to higher temperatures indicating that the interaction between copper and support was affected by this addition. Extra addition of potassium would further cause this shifting. Catalyst activity data show that proper addition of zinc can increase the activity of electroless copper catalyst in n- butanol dehydrogenation reaction and extra addition of potassium could further increase the catalyst activity.
