Abstract

Drop-in fuels have attracted great interest for automotive and aeronautical use. In this work, bio-hydrocarbons were obtained from palm kernel oil (palmist oil) within the distillation range of diesel and jet fuel. Green fuels were produced through the hydrodeoxygenation of palmist fat and its hydrolyzed product by using Pd/C as a catalyst. Th e process is effi cient for hydrodeoxygenation with conversions of up to 96% aft er 5 hours of reaction at 10 bar of H2 pressures and 30°C, which are mild conditions compared with the majority of the processes described in the literature. The hydroprocessing products were analyzed by infrared spectroscopy, nuclear magnetic resonance, thermal analysis and gas chromatography-mass spectrometry. The freezing temperatures of the biofuels were determined by DSC. Up to 5% deoxygenation products can be used in commercial jet fuel without compromising the cold fuel properties.
