Fossil fuels have increasingly become limited, whilst the need for them still continues to increase. This leads to an urgency for finding alternative fuels. Bioavtur is an alternative fuel for aircraft that can be synthesized from fatty acids such as stearic acid (C18) and palmitic acid (C16). In this research, a NiMoO₄/SBA-15 nanocomposite was synthesized to be used as a catalyst in the conversion of palmitic acid into paraffin through a deoxygenation reaction. The mesoporous SBA-15 was synthesized by sol-gel method and NiMoO₄ was dispersed into the SBA-15 surface through dry impregnation method with a variation of Ni:Mo mass composition (10:0, 2.5:7.5, 5:5, and 7.5:2.5). The successful synthesis of SBA-15 and NiMoO4/SBA-15 was confirmed by SAXS, XRD, XRF, BET and FTIR measurement. The SEM and TEM images indicates the morphology of worm-like and hexagonal structure with cylindrical channels of SBA-15. The XPS analysis revealed the NiMoO4 structure and oxidation states of Ni²⁺ and Mo⁶⁺, while NH₃-TPD shows the existence of various acid sites in the structure. The catalytic test was carried out in a 250-mL semi-batch reactor at 350 °C and the resulting product was analyzed using GC-MS. The results of the analysis with time variations show that as the reaction time increases, the % yield will also increase. At a reaction time of 150 minutes, the NiMoO₄/SBA-15 catalyst (2.5:7,5) produces the highest both conversion of palmitic acid (73%), and the yield of saturated C15 (66.4%).
