• 中文摘要： 本研究係探討Norbornadiene 於Pd/Al/sub 2/O/sub 3/觸媒上之氫化反應，研究係以批次淤漿反應器進行。蛋殼型觸媒之活性遠比均勻型觸媒活性高，這是因為均勻型觸媒內部的金屬在質傳控制時未被利用到的緣故。以蛋殼型觸媒作為反應動力學研究對象，反應速率對norbornadiene的濃度係零次反應，對空氣分壓為一次反應。反應速率式為- r/sub NN/ = 2.525*10/sup 2/ × exp(-4380/T)*P/sub H/sub 2// (mol/sec．gcatalyst)，反應符合 Horiuti-Polanyi反應模式，氫係解離吸附於金屬上，norbornadiene係強吸附在金屬上，而表面反應為速率決定步驟。
• 英文摘要： The hydrogenation of endo-endo dimer of Norbornadiene using Pd/Al/sub 2/O/sub 3/ catalysts have been studied in a batchwise slurry reactor. The egg-shell catalyst was much more active than the uniform one. This can be attributed to the incomplete utilization of active sites near the center of the catalyst sample with uniform metal distribution resulting from diffusional hindrance. The kinetic studies of the egg-shell catalyst showed that the reaction rate is zeroth order with respect to norbornadiene and first order to partial pressure of hydrogen. The rate equation can be expressed as, - r/sub NN/ = 2.525 *10/sup 2/ * exp(-4380/T) .bcdot.P/sub H/sub 2//(mol/sec.g catal.). The reaction follows the Horiuti-Polanyi mechanism. Hydrogen is dissociatively adsorbed on metal; NN is strongly adsorbed on metal and the rate-limiting step is surface reaction.
