Aviation fuels used in gas‐turbine engine powered aircraft are mainly obtained from the distillation of mineral oil. These jet fuel molecules present carbon chain length of C8 to C16 in the same range of fossil kerosene and have high calorific values and a great cold behaviour. With the increase in consumption of jet fuels, it has become extremely important to develop alternative fuels with adequate properties that could be capable of fulfilling the aviation industry requirements. In this context, aviation alternative fuel originated from sustainable raw materials must meet a set of safety requirements and should exhibit similar physicochemical properties to mineral kerosene. In this study the production of a short‐chain esters enriched biofuel using molecular distillation of FAME obtained from babassu oil was evaluated. Operational conditions were assessed to obtain high mass yields and high ester content in the carbon chain length range of kerosene. A fuel with properties close to those of aviation biofuels was obtained at 140 °C. At this temperature, more than 80 % of the esters in the product composition were within the desired range and there was a mass recovery higher than 88 %. In addition, the short‐chain esters enriched biofuel was blended with fossil kerosene at different concentrations and its properties were analyzed in order to study the effects of the gradual addition of this biofuel stream to commercial aviation kerosene. Density, heating value, freezing temperature, and pour point were evaluated. A mixture up to 6.0 % g/g accomplished the specification limits established by ASTM D1655.

“…Noted, it was discovered that adding Ni as a dopant boosts the efficiency of zeolite in HDO and cracking [20]. Although many researchers have focused on the modification of zeolite catalysts in HDO and cracking reactions by the addition of various active metals such as noble metals (Pt, Pd, Ru) [21][22][23] and transition metals (Ni, Co, Mo) [5,[24][25][26], nevertheless, to the best of our knowledge, less study has focused on a detailed comparison of the effectiveness of HDO activity over pure zeolite beta and HZSM5 catalysts. Due to aforementioned finding, therefore, this study will highlight on the impact of zeolite beta and HZSM5 on the behavior and hydrocarbon selectivity of the oleic acid (OA) HDO reaction towards the diesel fraction.…”

This study investigated the hydrodeoxygenation (HDO) of oleic acid (OA) that is abundantly found in palm oil for the production of renewable diesel. The effectiveness of mesoporous catalysts, HZSM-5 and zeolite beta, in favoring diesel hydrocarbons was determined. The catalysts were activated by calcination at 550 °C for 5 h and their physicochemical properties were determined using X-ray diffraction (XRD), scanning electron microscopy (SEM), temperature-programmed desorption using ammonia probe molecules (TPD-NH 3 ), and Brunauer-Emmett-Teller analysis (BET). XRD analysis of both zeolite beta and HZSM5 showed high crystalline size of 24 and 84 nm, respectively. BET analysis found that the zeolite beta catalyst had a greater surface area (648 m 2 g −1 ) than HZSM5 (465 m g −1 ) without significant differences in pore size and volume. According to the TPD-NH 3 study, zeolite beta had the most weak + medium acid sites when compared to HZSM5. It should be noted that HZSM5 also demonstrated the presence of strong acid sites. The optimal conditions for both catalysts were 350 °C, 4 MPa hydrogen pressure, and 5% catalyst load over a 2 h reaction period. From the results, the zeolite beta exhibited superior HDO reaction activity than HZSM5 with diesel selectivity ~ 77%.

“…This particular ability of SAPOs was also exploited by Rabaev et al [41] to produce jet fuels (48% yield) with a significant content of aromatics (12%) from soybean oil. With the aim to improve the economics of the process, several researchers have attempted to carry out the conversion of vegetable oils into jet fuels in the absence of hydrogen over zeolitic materials [42,43]. Higher temperatures were required to achieve deoxygenation of the vegetable oils (e.g., 550 • C), which resulted in lower alkane yields and faster deactivations.…”

Concerns about depleting fossil fuels and global warming effects are pushing our society to search for new renewable sources of energy with the potential to substitute coal, natural gas, and petroleum. In this sense, biomass, the only renewable source of carbon available on Earth, is the perfect replacement for petroleum in producing renewable fuels. The aviation sector is responsible for a significant fraction of greenhouse gas emissions, and two billion barrels of petroleum are being consumed annually to produce the jet fuels required to transport people and goods around the world. Governments are pushing directives to replace fossil fuel-derived jet fuels with those derived from biomass. The present mini review is aimed to summarize the main technologies available today for converting biomass into liquid hydrocarbon fuels with a molecular weight and structure suitable for being used as aviation fuels. Particular emphasis will be placed on those routes involving heterogeneous catalysts.
