最近已經大規模商業化從加氫可再生航空合成石蠟煤油（HRJ-SPK）生產可再生航空燃料。HRJ的第一步是通過加氫處理將生植物衍生的基於甘油酯的油轉化為直鏈烷烴。為了生產生物航空燃料，本研究集中在兩種不同催化劑之間的C15-C18烷烴的加氫處理，這是台灣最大的石油廢物之一的廢料油（WCO）在具有不同反應參數的固定床反應器中，包括反應溫度，氫氣壓力，LHSV和氫油比，在先前的文獻中高度報導了硫化的NiMo /γ-Al2O3和Pd/C。首先通過XRD，FTIR，TGA和SEM檢查新鮮和使用過催化劑，以研究加氫處理後的催化劑特性。通過觀察液體和氣體產物，還通過判斷加氫脫氧（HDO）的性能以及不同操作條件下的脫羰/脫羧作用來討論這兩種催化劑的最佳條件。所得到的液體產物，大多數為C15-C18正烷烴，可進一步裂化和異構化，生產符合航空燃料標準規格的航空燃料代用品。

Renewable jet fuel produced from hydro-processed renewable jet – synthesis paraffin kerosene (HRJ–SPK) has been commercialized in a large scale recently. The first step of HRJ is to convert biomass-derived, glyceride-based oils into straight-chain alkanes through hydro-processing. For the purpose of producing bio-jet fuel, this study focused on hydro-processing of waste cooking oil (WCO), which is one of the largest oil-based wastes in Taiwan, into C15-C18 alkanes over two different catalysts, pre-sulfied NiMo/γ-Al2O3 and Pd/C, as highly reported in the previous literatures, in a fixed bed reactor with varying reaction parameters including reaction temperature, hydrogen pressure, LHSV and H2-to-oil ratio. The fresh and spent catalysts were first examined through XRD, FTIR, TGA and SEM to investigate the catalyst characteristics after hydro-processing. Through observing the liquid and gas products, the optimal conditions for these two catalysts were also discussed by judging the performances of hydro-deoxygenation (HDO) as well as decarbonylation / decarboxylation with varying operating conditions. The resulting liquid products, mostly C15-C18 normal alkanes, can be further cracked and isomerized to produce jet fuel surrogate which meets the standard specifications of aviation fuel.
