• 中文摘要： 本研究主要探討相同鈀金屬含量呈蛋殼狀和均勻狀二種觸媒在異戊二烯選擇性氫化反應的影響。利用乙套連續滴流式反應器,使用此二種觸媒量測其氫化反應中的活性及其產物的選擇率。實驗結果顯示蛋殼狀觸媒比均勻狀觸媒有較佳的異戊二烯轉化率,及異戊烯的選擇率。以蘭格米奧-辛薛悟德方程式為基礎的動力學模式被導得。對於此二種觸媒而言,實驗和估計之間的數據其相對誤差在0.006範圍內,此一結果顯示這個數學模式足以用來描述反應的動力學。所求得模式中各參數可以非常合理用來解釋此二種觸媒的各種性能實驗結果。
• 英文摘要： The effects of palladium concentration profile on the selective hydrogenation of isoprene (IP) were investigated. The activity and selectivity for the hydrogenation reaction on eggshell and uniform profile catalysts were measured in a trickle bed reactor. The results indicated that the eggshell catalyst had higher activity and selectivity than those of the uniform profile catalyst. A kinetic model based on a Langmuir-Hinshelwood equation was developed. The relative variations between experimental and estimated data are within 0.006 for both uniform and eggshell catalysts. The results indicate that the model is adequate for describing the reaction kinetics. Moreover, the apparent kinetic parameters of the model correlated nicely with the performance of the two catalyst samples.
