“…Therefore, the use of biodiesel as a drop-in jet biofuel or even blended with fossil or bio-based fuels for aviation is not recommended, and should be limited to less than 5 ppm, according to ASTM D7566 [27]. For instance, Fatty Acid Methyl Esters (FAMEs) were obtained by the transesterification of methyl alcohol with oils from macaúba (Acrocomia aculeate) and palm (Elaeis guineensis) fruit kernel; further, the FAMEs were fractionated through atmospheric distillation to obtain short-chain esters (C 8 -C 14 ) aiming to blend them with fossil jet fuel; as a result, the blend (5 vol.%) of the light biodiesel cut (C 12 ) with the fossil jet fuel met the main technical standard properties (moisture content, density, distillation and flash point) [60].…”

The transition from fossil to bio-based fuels is a requisite for reducing CO2 emissions in the aviation sector. Jet biofuels are alternative aviation fuels with similar chemical composition and performance of fossil jet fuels. In this context, the Hydroprocessing of Esters and Fatty Acids (HEFA) presents the most consolidated pathway for producing jet biofuels. The process for converting esters and/or fatty acids into hydrocarbons may involve hydrodeoxygenation, hydrocracking and hydroisomerization, depending on the chemical composition of the selected feedstock and the desired fuel properties. Furthermore, the HEFA process is usually performed under high H2 pressures and temperatures, with reactions mediated by a heterogeneous catalyst. In this framework, supported noble metals have been preferably employed in the HEFA process; however, some efforts were reported to utilize non-noble metals, achieving a similar performance of noble metals. Besides the metallic site, the acidic site of the catalyst is crucial for product selectivity. Bifunctional catalysts have been employed for the complete process of jet biofuel production with standardized properties, with a special remark for using zeolites as support. The proper design of heterogeneous catalysts may also reduce the consumption of hydrogen. Finally, the potential of enzymes as catalysts for intermediate products of the HEFA pathway is highlighted.

“…The idea of using agricultural waste as a filler and/or reinforcement and marketing the resulting products has been of growing interest in recent decades. Investigations related to macaíba shell (MS), a byproduct of the food and cosmetic industry generated in the fruit processing process, stimulated this research 1‐4 . In addition, the abundance and low cost of MS has led to its use in different industrial applications without harming the environment.…”

Biocomposites based on macaíba shell (MS) and Polycaprolactone (PCL) were melting processed in this work; seeking better compatibility between PCL, MS was chemically treated with maleic anhydride (MA) and sodium hydroxide (NaOH), in addition, PCL‐g‐MA was used as compatibilizer. The biocomposites' performance was evaluated through Fourier transform infrared (FTIR), thermogravimetry (TG), contact angle, water absorption, scanning electron microscopy (SEM), the tensile experiments were executed according to ASTM D638 and the nonisothermal crystallization kinetics was performed from differential scanning calorimetry (DSC) scans using Pseudo‐Avrami, Ozawa, and Mo models. Chemical treated and compatibilized biocomposites presented better tensile behavior with no significant changes in the thermal stability. Higher HDT was verified on PCL/MS biocompounds due to the MS hardening effect, whereas higher contact angle and water absorption were computed for PCL/MS most due to new ways origin for the water get in as provided by MS. Related to crystallization kinetics Ozawa as displayed in the Appendix S1 failed to fit PCL/MS kinetics whereas Pseudo‐Avrami and Momay be safely used form processing purposes. Summing up, PCL/MS biocomposites were carefully investigated and gathered information may be promptly used in sundry applications as well as be added to the literature database.

“…In the effort to reduce GHG emission, bioaviation fuel emerged as the only promising solution due to its economic and environmental benefits 3 . It was reported that the blend of conventional aviation kerosene with 1% synthetic paraffinic biokerosene (SPK-like) fuel is capable to mitigate approximately 0.76% -0.81% of the CO2 emission 4 . Many international organisations such as Air Transport Action Group (ATAG), International Air Transport Association (IATA), North Atlantic Treaty Organization (NATO) and the European Union (EU) initiated the development of alternative aviation fuel, by funding projects to introduce green jet fuel to commercial flights through strategic applications.…”

According to Energy Outlook 2019 published by the US Energy information administration, aviation fuel consumption is expected to be more than double by the year 2050 as compared to the current usage. The increased cost of petroleum fuels and growing environmental concerns have made the aviation industry rely on biofuel in their fuel usage. Non-edible crops and algae are mainly used as feedstock for jet fuel production. There are many technologies such as blending Fatty Acid Methyl Esters (FAME), lipid hydroprocessing, Fischer-Tropsch synthesis, upgrading pyrolysis oils, Hydrothermal Liquefaction for jet biofuel production. However, sustainable production of jet biofuel is still under research. The current paper discusses the opportunities and challenges with these technologies.
