環己醇及環己基甲醇之氧化鋁與氧化鋯觸媒反應

Abstract

氧化鋁的觸媒反應已經被多人研究。研究結果發現，觸媒的酸鹼性會影響其反應機構，因而產生不同產物。另方面氧化鋯也可作觸媒及擔體，但它的觸媒性質仍未十分被了解。本研究，把環己醇及環己基甲醇在常壓，不同溫度或不同LHSV條件下通過氧化鋁或氧化鋯使其發生觸媒反應。本文討論各種觸媒對不同觸媒反應的影響。

The catalytic reactions of alumina has been extensively studied. It was found that the reaction mechanisms were governed by the acidity of the catalyst. However, the catalytic properties of zirconia, which also acts as support, is not as well understood as alumina. In this study, cyclohexanol and cyclohexyl methanol were passed over an alumina or zirconia catlayst at atmospheric pressure and at different temperatures or different LHSV. The effects of temperature and LHSV on the corresponding catalytic reactions were compared.
