隨著世界人口不斷增長，對於能源的需求日益增加，大量的石化燃料開發與燃燒增加溫室氣體的排放，發展可再生之生物燃料取代傳統石化燃料是當今各國首要關注議題之一。植物油可透過異相觸媒催化轉脂化反應生產生質柴油，於歐美各國已有商業應用實例，然而高含氧量導致低溫流動性差及能量密度低的缺點。加氫處理能有效去除三酸甘油脂中的氧原子，改善生質柴油的缺點，生產更高品質的替代生質燃料，且加氫處理生產設備能沿用化工廠固有之石油精煉基礎設施，提高商用可行性。應用適當異相雙功能型觸媒可降低加氫處理的反應環境條件與增加反應速率，有效達到增效作用，催化劑中的酸性點位具有裂解及異構化功能，金屬活性中心能提供氫溢流與脫氧之活性點位，異相催化方式則具有分離成本低的優勢。本實驗使用雙金屬雙功能型異相觸媒進行生質燃油生成反應，探討不同種類之觸媒在加氫脫氧反應上的表現。
本實驗使用ZSM-5型沸石作為載體，其具有高比表面積能均勻金屬活性點位，提高分散性，且能同時提供布忍斯特酸性點位與路易士酸性點位進行加氫裂解及異構化反應，使用經濟便利的含浸法擔載鎳鉬雙金屬於沸石表面進行觸媒改質，比較鎳金屬擔載量對鎳鉬雙金屬觸媒催化加氫脫氧反應之影響，本實驗亦透過質譜儀分析液相產物與氣相產物之成分組成。使用過之雙金屬觸媒使用離心機與液相產物分離後，透過FT-IR與ICP討論觸媒失活程度，評估耐用性。由實驗結果可知，於大豆油：十氫萘＝1：3體積比的條件，在325°C、氫氣壓力40 bars的反應環境下以5 wt%觸媒使用量催化加氫脫氧反應，增加鎳金屬擔載量能減緩裂解反應，提高選擇率。

The hydrotreatment of soybean oil to liquid alkane fuels was conducted in presence of zeolite ZSM-5 supported bimetallic Ni and Mo catalysts. The bimetallic Ni and Mo catalysts, aka NiMo/ZSM5, were successfully prepared on zeolite ZSM-5 by incipient wetness impregnation method. Prior to the hydrotreatment process, NiMo/ZSM5 were activated with hydrogen stream at 500°C for 1 h, i.e. reducing NiMo/ZSM5 from an oxidation state to a reduction state denoted as NiMo(R)/ZSM5. The catalyzed hydrotreating reaction of soybean oil was conducted in a semi-batch autoclave equipped with magnetic stirrer at 325°C under 40 bars of pure hydrogen. ICP-OES was conducted to characterize the loading of Ni and Mo as 9.4 wt% and 4.8 wt%, respectively, based on the mass of ZSM-5. After 4 hours hydrotreatment, the highest yield near 25% could be achieved. Various instruments were employed to characterize the catalysts, such as XRD, SEM, TEM, BET, SQUID, H2-TPR and FT-IR. The conversions were determined by analyzing liquid by GC-FID. In addition, isomerized alkanes and gas phase product were revealed by GC-MS.
