生質能源為再生能源中之一環，其重要性亦於近幾十年中與時俱增。為了研究生質物於熱降解時之特性，竹子之前處理與微藻之動力式分別於本研究之第一與第二部分進行測試與分析。其中第一部分探討了生化溶液－NOE-7F用於生質物－竹子之前處理上，對於其在結構、反應性以及焙燒等方面之影響。第二部分則藉由建立三種不同微藻之裂解動力式，進而分析其中碳水化合物、蛋白質與脂質之熱降解特性。
本實驗中第一部分為了探討浸泡時顆粒大小之影響，實驗選用兩種模式－Mode 1與Mode 2。Mode 1中竹子先經過破碎之處理，再浸泡於生化溶液中，而Mode 2則是相反之操作順序，兩種模式皆浸泡於五種不同之持續時間。結果顯示於Mode 1之操作下，竹子中之半纖維素被生化溶液消耗，進而改善竹子之均質性。此結果類似於製造生質酒精上之酶水解前處理。而在相同操作天數下，Mode 2之效果未達Mode 1之顯著。前處理後竹子在點燃與燃盡溫度上皆有提升，表示儲存安全性之提升與反應性之降低。另外，生化溶液前處理對於氫碳比、氧碳比與高位發熱質則較無顯著之改變。但纖維素之結晶結構在Mode 1與Mode 2之處理後皆有變化。結果建議若要應用於燃料，生質物需再經過焙燒處理，而Mode 2因其之高焙燒強度則較適用於斯。
第二部分中，動力式之建立乃基於獨立平行反應模型（IPR model），同時藉由粒群演算法（PSO）計算活化能與前置因子等動力式所需參數，以達到預測數據與實驗之最佳符合度。結果顯示與微藻裂解之導數熱重分析（DTG）實驗相比，由動力式在獨立平行反應模型與粒群演算法計算下所建立之曲線可達97.9 %以上之符合度。從計算結果，三種藻類中之碳水化合物、蛋白質與脂質之活化能範圍依序為25-53 kJ mol^-1、96-188 kJ mol^-1與40-59 kJ mol^-1，而此三種物質之裂解溫度範圍依序為130-574 °C、209-373 °C與200-766 °C。由結果可證明在獨立平行反應模型與粒群演算法之計算下，可以建立一定符合度之裂解反應動力式。

Bioenergy, a type of renewable energy, has been getting more important along the last few decades. To investigate the characteristics of biomass thermal degradation, the pretreatment of bamboo and kinetics of microalgae are tested and analyzed in the present study, which are divided into two parts. In the first part, a bio-solution of natural organic enzyme-7F (NOE-7F) is used to pretreat bamboo, with emphasis on the influence of the pretreatment upon the structure, reactivity, and torrefaction of the biomass. In the second part, the kinetics of microalgae pyrolysis is investigated to analyze the thermal degradation of carbohydrates, proteins and lipids in different species of microalgae.
In the first part of this research, two different operating modes accompanied by five different soaking durations are considered. In Mode 1 the bamboo is ground followed by pretreated by the bio-solution, and an inverse procedure is used in Mode 2. The results indicate that, with the operation of Mode 1, NOE-7F removes hemicellulose in the bamboo significantly, thereby improving the homogeneity of the biomass. This pretreated bamboo may be feasible for enzymatic hydrolysis to produce bioethanol. The penetration of the bio-solution into block bamboo becomes the controlling mechanism under Mode 2 operation, and therefore relatively less hemicellulose is consumed from Mode 2. The ignition and burnout temperatures of the pretreated bamboo are higher than those of the raw bamboo, revealing the lower reactivity and higher storage safety of the former. The atomic H/C and O/C ratios as well as the calorific value of the bamboo are insensitive to the pretreatments, whereas the crystalline structure of cellulose is affected by the bio-solution to a certain extent, regardless of Mode 1 or Mode 2 operation. This suggests that torrefaction is required if the pretreated bamboo is employed as a fuel. The pretreated bamboo with Mode 2 is more suitable for torrefaction because of higher torrefaction severity.
In the second part of this research, the pyrolysis process of microalgae is examined by thermogravimetric analysis (TGA). The independent parallel reaction (IPR) model is adopted to obtain the necessary parameters for pyrolysis kinetics, and a kind of evolutionary computation, particle swarm optimization (PSO), is employed to maximize the fit quality of the simulated data. The characteristics of the thermal degradation of different microalgae are compared with each other. The results suggest that the thermal degradation curves of the three microalgae can be predicted with a fit quality of at least 97.4%. The activation energies of carbohydrates, proteins, and lipids in the microalgae are in the ranges of 53.28-53.30, 142.61-188.35, and 40.21-59.23 kJ mol^-1, respectively, while the thermal degradation of carbohydrates, proteins, and lipids are in temperature ranges of 164-497, 209-309, and 200-635 °C, respectively. It is proved in this work that the IPR model and the calculation of the PSO can be used to predict the pyrolysis kinetics of microalgae to a good level of fitness.
