摘要

欲將有機物質熱重分析(TGA)數據進行動力學分析時常面臨選擇複雜反應式之困難，本論文提出一基於阿瑞尼斯反應動力之普遍適用之方案，將前指數參數(pre-exponential factor)、活化能(activated energy)及反應級數(reaction order)均視為轉化率(conversion factor)之連續函數。此方法不需假設複雜之反應模式，因此為一泛用方法。本論文中將此方法套用於2種油污泥之TGA數據，得到之關聯式與實驗數據極為相近。

Interpretation of thermogravimetric analysis (TGA) data of organic materials usually faces difficulties for distinguishing the weight versus temperature data into a complex reaction scheme. This work proposed a general scheme to converting the TGA data into an Arrhenius-type kinetics that regarded the pre-exponential factor, the activated energy, and the reaction order as functions of conversion. The TGA data of two oily sludges were used as demonstrative examples. Agreement between obtained correlation with the experimental data was satisfactory.
