First, three metals, nickel, cobalt, and molybdenum, were selected to be loaded on SAPO-11 separately and their activities were tested over the model feedstock, n-hexadecane. Among the three catalysts, nickel SAPO-11 shows the highest conversion of 70%. Second, the performance of Ni/SAPO-11, synthesized with (Ni/SAPO-11(CA)), and without (Ni/SAPO-11) citric acid was investigated with the hydro-processed alkanes derived from palm oil for the production of hydro-processed renewable jet fuel (HRJ). Catalyst metal particle size, structure, textural properties, acidity, and reduction degree were detected through transmission electron microscope (TEM), X-ray diffraction (XRD), N2 adsorption/desorption, pyridine-adsorbed infrared spectroscopy (Py-IR), and temperature programmed reduction (TPR). The product compositions over the Ni/SAPO-11(CA) catalyst show higher selectivity toward the carbon chain length of jet fuel (C8-C14) for 48% compared to the Ni/SAPO-11. Through the Taguchi method, the optimal operating conditions were found to be: temperature of 380°C, pressure of 52 bar, liquid hourly space velocity of 0.5 h−1, and H2-to-feedstock ratio of 1250, which yielded in 73% conversion to HRJ with 6.1 isomer-to-normal (I-to-N) alkane ratio. The derived cetane number (DCN) and the flash point of HRJ were also obtained to be 56 and 56°C to confirm the compatibility of HRJ with conventional jet fuel.
