In our developing and changing world, the use of energy resources is becoming important. With the development of the aviation industry all over the world, the need to use more innovative, more sustainable resources emerges. When the demands in the transportation sector from past to present are examined, the transformation in energy resources will be inevitable. As stated, all studies have focused on the energy resources that reduce the environmental impact, sustainability, environmental friendliness, costs and dependence on oil producing states. In this study, the study of aviation fuels from past to present, its production, environmental impact, sustainability and the returns of alternative aviation fuels are discussed in detail. It is concluded that the world's developing and changing aviation sector should switch to sustainable alternative fuels as soon as possible.

“…High demand for jet fuel and the shortage of oil resources have attracted extensive research interest to study the processes of biological transformation 1–4 . The two‐stage hydrogenation route to produce jet fuel includes the hydrodeoxygenation of vegetable oil or animal fat and the hydrotreatment of long‐chain alkanes.…”

The hydrotreatment of n‐C16 over Pt/HPMo/SBA‐15 and the investigation of diffusion effect using a novel W‐P criterion

A series of Pt/HPMo/SBA‐15 catalysts with the pore size as a single variable were prepared to elucidate the internal diffusion effect on the hydrotreatment of n‐C16. A novel model was developed to calculate the Weisz‐Prater number (NW‐P) because the traditional model relies on excessive empirical reference values and affects the accuracy remarkably. The utilization of the internal effectiveness factor, Thiele modulus, and the apparent activities over catalysts with different diffusion capacity gave rise to NW‐P with improved accuracy, which can also be extended to other heterogeneous catalytic systems with macromolecules as reactants. Combining the novel model with the diffusion–reaction kinetic method, a conclusion has been drawn that the formation of m‐i‐C16 is more susceptible to internal diffusion than the consumption of n‐C16. Besides, the pore size should be not less than 10 nm to avoid the step‐limitation of internal diffusion, in the premise of adequate acid sites.

“…Besides, the hydrocracking process was carried out using a sulfided NiMo/Al 2 O 3 catalyst to produce bio-jet fuel (bioavtur) from natural triglycerides/coconut oil. The operating conditions of the process were at temperature of 280-380 °C, the pressure of 30 bar, liquid hourly space velocity (LHSV) of 1.0-3.0/h, and H 2 /feed volume ratio of 600 Nm 3 /m 3 ) [21]. Meanwhile, Al-Muttaqii et al [22] and Widayat et al [23] have produced biokerosene and biofuel from coconut oil using a Ni-Fe/HZSM-5 and Zn/HZSM-5 catalyst through a hydrocracking process.…”

Hydrocracking of Coconut Oil on the NiO/Silica-Rich Zeolite Synthesized Using a Quaternary Ammonium Surfactant

et al. 2020

NiO/silica-rich zeolite catalysts were used for coconut oil hydrocracking. The catalyst was prepared with a mixture of Na2SiO3, Al(OH)3, NaOH, and quaternary ammonium surfactants. The surfactant was varied of types like as tetrapropylammonium bromide (TPAB) and cetyltrimethylammonium bromide (CTAB). The acidity of the silica-rich sodalite zeolites enhances with the increase in nickel oxide added through a wet impregnation. The hydrocracking process was carried out by a semi-batch method. Liquid products were analyzed using GC-MS. The results showed that the addition of surfactants increased the catalyst surface area and acidity. Meanwhile, the presence of nickel oxide increases the acidity of the catalyst. The hydrocracking results showed an increase in gas products when the surface area was high, i.e., 23.781% in silica-rich sodalite zeolite without template (Z), 32.68% in silica-rich sodalite zeolite with tetrapropylammonium (ZTPA), and 39.673% in silica-rich sodalite zeolite with cetyltrimethylammonium (ZCTA). The presence of NiO increased the liquid product and the selectivity of the bioavtur fraction (C10-C15), where the highest percentage of liquid product was 60.07% at NiO/ZTPA.
