為了促進加氫處理之綠色柴油成為傳統柴油以及轉脂化生質柴油的替代品，製程研究、技術經濟分析以及量產系統是眼下必須完成之研究。事實上，國內針對將植物油透過加氫反應產生綠色柴油之製程研究並不多。因此，本研究在NiMo/γ-Al2O3催化劑上以不同的反應溫度，壓力，重時空速（WHSV）和氫油比進行實驗製程；並透過GC-MS/FID/TCD等儀器測定其轉化率，選擇性和GC產率之變化。由上述結果表明了綠色柴油的競爭力，因此量化生產之方法以及系統優化也於此研究中一併完成。在系統優化後，綠色柴油之實際產率有著顯著提升。而量化系統中所使用之NiMo/γ-Al2O3催化劑也被發現可進行再活化，並且在油品轉化率保持在 100 %的情況下使產油量提升將近40倍。此外，本研究也針對系統之能量轉換效率以及碳排放進行分析。而透過優化系統所生產之綠柴也被送往SGS進行其油品性質之檢測。
For the purpose of promoting hydro-processed Green Diesel as the local replacements of traditional diesel and transesterification biodiesel, the experimental investigation and mass production method should be carried out. In fact, domestic experimental studies focusing on Green Diesel production in Taiwan were still missing. As so, the experiment was conducted with varying reaction temperature, pressure, weight hourly space velocity (WHSV) and H2 to oil ratio over the NiMo/γ-Al2O3 catalyst and the conversion, selectivity and GC yield were determined by GC-MS/FID/TCD. As the results shows the competitive of Green Diesel, mass production method and system optimizing were established. The production yield has been slightly promoted after the system optimization, the NiMo/γ-Al2O3 catalyst can be reactivated after the regeneration treatment and the total scale has been promoted while the conversion remains 100 %. In addition, the energy conversion ratio and production carbon footprint were also investigated in this study. The Green Diesel produced through the mass production system were sent to SGS Corporation and the fuel properties were further analyzed.
