摘要

生物質能源是一種可再生能源，目前生物質轉化能源工程技術的應用，主要是採用木質纖維有機質材料，將其經由轉化程序技術產出糖類，進而分離純化及發酵產出生質酒精燃料，以替代傳統石化燃料的使用。
本研究是規劃、設計及建置一套機電自動化的膜分離純化系統之製程設備，採用生物質的狼尾草渣為原料，以經由蒸爆處理後產出具有低聚木糖成份的混合液為研究對象，以產出無發酵抑制物的低聚木糖混合液成品為主要目標。
本研究與實驗共分為兩個階段，第一階段的研究是以採用全迴流的操控運行試驗法，先進行過濾膜的分離及純化主系統設備的規劃、設計、建置及功能測試；其次再以購買市售的藥品，再依據蒸爆系統所產出蒸爆液的各項成分及濃度比例分析數據，以調配出實驗所需的低聚木糖模擬混合溶液樣品；再以全迴流的方式操作，藉此評估此分離純化系統之過濾膜的分離效能。第二階段的研究是加入儀控元件、器件及OPLC(HMI＋PLC)裝置的人機介面監控操作。以溫度監控系統來調控過濾系統的循環液溫度，使濾液的溫度保持穩定。以自動且即時補水控制功能，使循環液能保持在某些濃度值的範圍內，以達到良好的滲濾效果。經由這研究及實驗結果, 取得相關流程參數與過濾效果等經驗資訊，期望在短期內能達成製造商業級過濾膜的分離純化系統的願景。

Biomass energy is a type of renewable energy. The primary application of biomass-converted energy engineering technology involves converting lignocellulosic organic material into sugar, employing separation, purification, and fermentation processes to generate biomass ethanol fuel, which can replace traditional fossil fuels.
In this study, an electromechanical automation system was designed and constructed to separate and purify membranes. Napier grass was used as the biomass material, to which a steam explosion treatment was applied, producing a mixture containing xylooligosaccharides. The objective of this study is to produce a xylooligosaccharide mixture that lacked a fermentation inhibitor.
The experiment comprised two phases. First, a total reflux method was adopted to plan, design, construct, and test a filtration membrane separation and purification system. Based on the composition and concentration ratios of the resulting steam explosion liquor, commercially available drugs were used to produce a simulated xylooligosaccharide mixture sample. Next, a total reflux operation was used to evaluate the separation effectiveness of filtration membrane in the separation and purification system. Second, instrument control components, devices, and a human-machine interface (HMI) apparatus that comprised an operator panel logic controller (OPLC = HMI + programmable logic controller) are employed. A temperature monitoring system was used to regulate and control the temperature of the circulating fluid of a filtration system, maintaining a constant filtrate temperature. An automated instant water replenishment system was used to maintain the xylooligosaccharide concentration levels of the circulating fluid in a certain range, facilitating optimal percolation. The experimental results provide relevant information, such as process parameters and filtration effects, which facilitates the goal of producing commercialized filtration-membrane separation and purification system in near future.
