20.500.12556/RUL-135519 Recent advancements in catalytic conversion pathways for synthetic jet fuel produced from bioresources Sustainable Aviation Fuel (SAF) has become an important measure in the aviation industry’s efforts to mitigate carbon emissions and reduce their overall environmental impacts. However, commercial usage is relatively stunted due to a plethora of drawbacks in the production process and economic feasibility of the fuel. In this study, the currently accepted technologies for producing synthetic jet fuels under the American Society for Testing Material (ASTM D7566) standard specification for aviation turbine fuel are reviewed. The emphasis is placed in terms of their reactions, type of catalysts used for the conversion pathways of Fisher-Tropsch (FT), Hydroprocessed Esters and Fatty Acids (HEFA) and Alcohol-to-Jet (ATJ), and the use of biomass resources as feedstock. The advancement in the production process and physicochemical properties of the uncertified biojet fuels are reviewed and discussed. Generally, Co- and Fe-based catalysts are commonly used for the FT process, while bimetallic catalysts consisting of Pt, Pd, Ni and Mo have shown excellent activities and selectivities for the HEFA process. For the ATJ process, zeolites such as HZSM-5, beta and SAPO have shown remarkable ethanol dehydration efficiency, while TiO2 and ferrierite have been studied for the combined iso-butanol dehydration and oligomerisation processes. Fundamental factors influencing the reaction efficiency including the feedstock properties, reaction conditions, catalytic reusability and catalyst supports are discussed. Finally, the key challenges and prospects for biojet fuel commercialisation are addressed. biojet fuel catalyst production pathway sustainable aviation fuel hydroprocessed esters fatty acids biojet gorivo katalizatorji proizvodna pot trajnostno letalsko gorivo hidroprocesirani estri maščobne kisline true false true Angleški jezik Slovenski jezik Članek v reviji 2022-03-17 10:06:11 2022-03-17 10:06:16 2025-02-05 11:14:24 0000-00-00 00:00:00 2022 0 0 24 str., art. 114974 Vol. 251 Jan. 2022 0000-00-00 PostprintKoncna Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 2024-01-01 662:629.7:502.131.1 0196-8904 10.1016/j.enconman.2021.114974 98610435 RAZ_Goh_Brandon_Han_Hoe_2022.pdf RAZ_Goh_Brandon_Han_Hoe_2022.pdf 1 5E08FC3E824EDD4BF07CB221438E5579 8cbc9164fc0c045d0ffd1b0293a1789c743b86ed407e1f07b91f4785dd3a61ac 7357379d-a5d8-11ec-8556-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=154647 https://www.sciencedirect.com/science/article/pii/S019689042101150X 1 7e9378f1-a5d1-11ec-8556-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=154637 Fakulteta za strojništvo 0 0 0
