• 中文摘要： 本文藉由熱力學平衡的研究以及利用CuPt雙金屬含浸在各種不同的酸性擔體為觸媒,進行正丁烷的轉化反應。由熱力學平衡的結果得知以高溫及低分壓的正丁烷為反應條件,有利於異丁烯的生成。反應的結果顯示CuPt- Hsilicalite和CuPt-borosilicate具有較高的活性,但主要的產物為裂解產物C/sub 1/-C/sub 3/,歸因於這些擔體的酸性基太強; CuPt-AIPO/sub 4/-5、CuPt-.gamma.- alumina和CuPt-amorphous borosilicate無任何異丁烯的生成,乃因為這些觸媒酸性太弱; 而在本研究中, CuPt-SAPO-11與CuPt-Amorphous aluminum silicate的酸基較適合將丁烯異構化為異丁烯,尤其以CuPt-SAPO-11是本研究正丁烷脫氫異構化為異丁烯的觸媒中,在該反應條件下,效果最好的觸媒。
• 英文摘要： Butane conversion was investigated by thermodynamic equilibrium and by butane dehydroisomerization on CuPt impregnated on acid type supports. The production of isobutene was observed from the equilibrium study to be favorable under low partial pressure of n-butane at reactor inlet and a high reaction temperature. The study of butane conversion over CuPt impregnated on different acid type supports revealed that CuPt-Hsilicalite and CuPt- borosilicate were more active than the other catalysts but the primary products were cracking species C/sub 1/-C/sub 3/ owing to strong acid sites on the supports. CuPt-AlPO/sub 4/-5, CuPt-.gamma.-alumina and CuPt-amorphous aluminum silicate did not produce any isobutene owing to its low acidic nature of the supports. SAPO-11 and amorphous aluminum silicate were concluded in this study to possess acid sites for the isomerization of butene to isobutene. CuPt-SAOP-11 was also observed to be the best catalyst among those investigated for the dehydroisomerization of butane to isobutene.
