N2 - Because not conflict with human and animal food resources, non-food vegetable oils are promising sources for developing liquid advanced biofuel. Directly upgrading non-food vegetable oils to hydrocarbon fuels is likely offering reasonable profit margin for bio-jet fuel production. The sunflower oil extracted from residues that were produced in sunflower seed de-hulled processing is inedible due to its quality not meeting food standards. Genetically modified sunflower grown on margin lands can also provide one possible non-food source for sustainable biofuel production source since it doesn't compete with the use of arable lands. Sunflower oils produced from those non-food sources were cracked on ZSM-5 catalysts in a fixed-bed reactor at three temperatures, 450 °C, 500 °C, and 550 °C. Characterization of the upgraded sunflower oils, advanced hydrocarbon fuel and distilled residual fuel, including pH value, density, water content, viscosity, heating value, and fatty acid profile, was carried out. The composition of non-condensable gases generated during the catalytic cracking process was also analyzed. The effect of the reaction temperatures on the upgraded sunflower oils' yield and quality was discussed. The results showed that reaction temperatures affected the yield and properties of upgraded sunflower oils. The highest yield of advanced hydrocarbon fuel from raw sunflower oils was 21.1% at 550 °C. Upgraded sunflower oils were a mixture of un-cracked oils and hydrocarbons. After distillation, the advanced hydrocarbon fuel had lower viscosity, moisture content and density. The non-condensable gases contained C, - C5 light hydrocarbons, H2, CO, CO2, etc. The reaction temperatures had significant effect on the concentrations of these compounds during catalytically cracking sunflower oils.
