觸媒氧化技術是現今富有潛力及經濟效益之VOCs處理技術，然而多半需要在高溫條件下才得以有效去除VOCs，若使用低溫觸媒可降低為達到高溫條件所衍生的龐大能源成本。銅質觸媒為極具優勢之低溫觸媒，因此開發出高效的銅質觸媒有其重要性。
本研究藉由含浸法自製不同銅氧化物與氧化鋁比例的低溫觸媒，發現材料比例對觸媒的表面組成與結構有極大影響；並探討銅質觸媒於固定床反應器對苯乙烯的降解表現，以具尖晶石結構之10 wt%CuO/Al2O3觸媒的降解效果最佳。於操作參數實驗中，可發現10 wt%CuO/Al2O3觸媒對苯乙烯的降解效果隨苯乙烯濃度、空間速度或相對溼度增加而減少，且隨氧氣濃度增加而升高。衰化實驗中，觸媒於258oC以上時可維持高降解效率。研究中輔以TGA、XRD、XPS、SEM等精密儀器分析，佐證觸媒結構隨成分改變，並分析出觸媒反應前後之變化。另以MVK模式、L-H模式及E-R模式擬合以了解觸媒降解苯乙烯之反應動力。

Catalytic oxidation using metal oxides is one of the promising and economical technologies for the reduction of volatile organic compounds (VOCs). However, most catalysts can only remove VOCs effectively under high-temperature conditions. The use of low-temperature catalysts can save considerable required energy costs. The application of copper-based catalyst low-temperature reaction is advantageous; therefore, the development of copper catalysts with high VOCs removal performance is essential.
In this study, a series of low-temperature catalysts with various proportions of copper oxides to aluminum oxide were made by the impregnation method. It was noticed that the surface composition and structure of the catalyst would be strongly affected by the ratio of copper oxides and aluminum oxide. The catalytic efficiency of the copper catalysts for styrene removal was examined in a fixed-bed reactor, and the result showed that the 10 wt%CuO/Al2O3 catalyst with spinel structure exhibited the best performance. In the operating tests, the styrene removal efficiency of 10 wt%CuO/Al2O3 catalyst decreased under higher styrene concentration, space velocity, or relative humidity but elevated with increasing oxygen concentration. In the deactivation tests, the catalyst could maintain high catalytic efficiency when the operating temperature was above 258oC. Various instruments, such as TGA, XRD, XPS, and SEM, were also used to examine the structural difference among various prepared catalysts and to observe the change in the catalyst’s properties before and after the reaction. Furthermore, the kinetics of the catalyst for styrene removal would be fitted with MVK, L-H, and E-R model.
