英文摘要 | 由TGA實驗結果推導出PU/CFCs廢棄物熱解之活化能(Ea)及前指數常數(lnA)之值分 別為 25-30 kcal/mol 及 33 hr-1, 實驗也顯示 PU 泡棉熱解並不受 CFCs 存在之影響, CFCs-141b 通過草酸鈉固定床反應器 (T=563 K), 幾乎完全礦化 (mineralization),殘餘 之固體物很容易在升高溫度至 623 K,分解成碳酸鹽。 此外,生成之 NaF 亦可回收再利用 。 matrix, respectively. It indicates that pyrolysis of the PU polymer (at elevated temperatures) is not affected by the presence of CFCs. In a single pass throught the heated sodium oxalate bed (573 K) caused a complete mineralization of CFC-141b. |
