The role of single metal loaded on SAPO-11-based hydroprocessing catalyst to produce renewable jet fuel was investigated in this work. First, three metals, nickel, cobalt, and molybdenum were loaded on SAPO-11 and their activities were tested over model feedstock, n-hexadecane. Among the three metals, nickel showed highest conversion of 70%. Then, the Ni/SAPO-11 synthesized with (labelled as Ni/SAPO-11(CA)) and without citric acid activities were tested over hydroprocessed alkanes to produce hydroprocessed renewable jet fuel (HRJ). The Ni/SAPO-11(CA) catalyst showed higher selectivity towards shorter hydrocarbon chain (C8 – C14) of 48% than the Ni/SAPO-11, therefore it was chosen as the catalyst to produce HRJ. Next, the catalyst properties, which consisted of its structure, textural properties, surface morphology, and acidity, were tested. After that, the reaction parameters were optimized using Taguchi method. The best parameters were: temperature 380°C, pressure 750 psi, LHSV 0.5/h, and H2-to-feeedstock ratio of 1250, which yielded in 73% hydroprocessing renewable jet fuel (HRJ) with 6.1 I/N ratio. Finally, the derived cetane number (DCN) and the flash point of HRJ were tested. The HRJ DCN was 56, higher than that of Jet-A1 and JP-5. The flash point of HRJ was 56°C, which showed compliance to the ASTM D7566 standard of above 38°C.
