• 中文摘要： 本研究在探討酚在次臨界條件下之熱分解,此氧化分解程序是利用過氧化苯甲醯基(BPO)作起始劑以產生氧化自由基,在低於175.degree.C並有足夠酚濃度的條件下,酚的氧化分解反應為一階,當反應溫度高於175.degree.C和低酚濃度時,氧化反應開始偏離一階。本研究發現BPO濃度在50.mu.g/m/sup 3/之下,酚氧化反應加快約30%,為了達到很好的液相生化需氧量(COD)去除,反應溫度至少需維持在325.degree.C以上。
• 英文摘要： Subcritical thermal decomposition of phenol is investigated in the present work. Benzoyl peroxide (BPO) is employed as an initiator for generating the free radicals essential for initiating the phenol oxidation process. The BPO-initiated phenol oxidation is found to follow the first- order at a reaction temperature lower than 175.degree.C and sufficiently high phenol concentration. At a higher temperature and/or at a low phenol concentration, deviation from the first-order kinetics is observed. Addition of benzoyl peroxide up to 50.mu.g/m/sup 3/ is found to be able to speed up the oxidation process by as much as 30%. It is also observed that to achieve a good reduction in chemical oxygen demand (COD) of the aqueous solution, operation of the oxidation process at as high temperature above 325.degree.C is necessary.
