Jideani, TSeroka, Ntalane SKhotseng, L2025-09-252025-09-252025-092191-1363https://doi.org/10.1002/open.202500353http://hdl.handle.net/10204/14415Biomass-derived bio-oil, produced through thermochemical methods such as pyrolysis and hydrothermal liquefaction, has immense potential as a renewable feedstock for aviation fuels because of its renewable nature and the potential to significantly reduce greenhouse gas emissions. The development of biojet fuel from renewable sources, such as biomass, is a critical step toward achieving global energy sustainability and reducing the carbon footprint of the aviation industry. This review aims to provide a comprehensive analysis of the advances in catalyst design to upgrade biomass-derived oil to biojet fuel. The review will also explore the mechanisms by which these catalysts operate, the optimization of catalytic processes, and the performance metrics used to evaluate their efficiency. Recent case studies demonstrate the effectiveness of catalyst design in enabling efficient and sustainable conversion of biomass-based bio-oil into high-quality fuels, advancing the viability of renewable energy sources in aviation and beyond.FulltextenBio-mass derived bio-oilEnergy sourcesFossil fuelsArticlen/a
