Abstract The aviation industry has set ambitious goals for reducing carbon emissions, with the International Civil Aviation Organization targeting net-zero emissions by 2050. Bio-jet fuel is expected to play a crucial role in achieving this target, and demand bio-jet projected rapidly increase. Bio-oil from fast pyrolysis of lignin, such as waste wood, considered promising alternative production through processes hydrodeoxygenation. In study, physical properties compositions produced wood-derived bio-oil blended petroleum-based jet well their changes during 16 weeks storage were investigated. Consistently, 0%, 10%, 50%, 100% fuels prepared. After aging, total acid number all-blended showed sharp increase 12 weeks, reaching over 0.1 mg KOH/g. Additionally, kinematic viscosity steady whereas oxidative stability decreased approximately 20% at alone. final boiling point increased up higher blends average molecular weight increased. high olefin content, which can further storage, leading decrease combustion characteristics. This study suggests that using 10% aircraft safe considering stability, but research required confirm finding.
