“…For the same reaction conditions of 18 min, 350˚C, and 4 bar H 2 , different percentages of MB catalyst: 1%, 2%, 3%, 4% were added to produce bio-jet fuel. The results of these experiments are shown in Figure (7). It is seen that the bio-jet fuel production yield increased with the increase of MB percentage.…”

Biofuels such as biodiesel and bio-jet fuel are‏ important sources of renewable energy, which has to be added to petroleum fuels in different ratios for environmental purposes. Biofuels in general, can be produced from several raw agriculture materials. Currently, the most important biofuel is the bio-jet fuel, used for partial replacement of jet fuel from petroleum origin. The most promising method for bio-jet fuel manufacture is the catalytic hydrocracking of a low-cost raw vegetable oil such as non-edible Jatropha oil. The type of product and its quality and quantity depend on the process conditions such as reaction time, temperature, and catalyst type, form, and amount. Heterogeneous catalysts play an important role in this process. The present study aims to the production of bio-jet fuel by hydrocracking of Jatropha oil conforming to ASTM specifications by the selection and preparation of an economic inorganic catalyst. The 4% catalyst was used in the production of biojet fuel under the obtained optimum operating conditions of 350˚C, 4 bar H2, 18 min, and followed by fractionation tower. The products were tested and their specifications conformed to the ASTM specifications, viz the freezing point (-56˚C), the flash point (53˚C), and existent gum content (5.9 mg/100 ml).

“…Particularly, one of the greatest challenges currently in this field is the development of a sustainable alternative for powering the aviation sector, where the use of electric or hydrogen-based technologies is still far from commercial application. The aviation sector utilizes approximately 3% of the world’s fossil fuels, generates around 2% of greenhouse gas emissions, and accounts for around 11–12% of all transportation-related CO 2 emissions. , In the current context, with a constant increase in fossil fuel prices, together with increasing environmental concerns and regulations all over the world, the development of sustainable biofuels is one of the best alternatives for replacing traditional jet fuel in the aviation sector. Thus, the European Green Deal sets out the need to reduce air transport emissions by 50% by 2050 as compared to 2005, specifically including the promotion of sustainable aviation fuels (SAFs), fully compatible with existing infrastructures and engines, as one of the key solutions .…”
