TotalEnergies has filed a patent for a jet fuel composition that combines petroleum-derived jet fuel with a renewable component made of hydroprocessed esters and fatty acids. The composition, containing 1 to 50% of the renewable component, has a freezing point of -40°C or below. The petroleum-derived jet fuel component has a specific content of C9-C12 normal paraffins, and the freezing point of the composition is lower than the theoretically calculated freezing point.

Jet fuel composition with improved cold properties using renewable component
A recently filed patent (Publication Number: US20230313061A1) describes a jet fuel composition that includes both a petroleum derived jet fuel component and a renewable component made up of hydroprocessed esters and fatty acids. The composition contains 1 to 50% of the renewable component and has a freezing point of -40°C or below. The petroleum derived jet fuel component has a content of C9-C12 normal paraffins ranging from 17% to 30% by weight. Importantly, the freezing point of the jet fuel composition is lower than what would be expected based on a linear relation.
The patent also outlines a method for producing the jet fuel composition. The method involves mixing the petroleum derived jet fuel component with the renewable component to achieve a composition containing 1 to 50% of the renewable component and having a freezing point of -40°C or below. The petroleum derived jet fuel component should have a total content of paraffins ranging from 40% to 55% by weight. The renewable component can be produced from various oils, including vegetable oil, animal fat, inedible highly saturated oils, waste oils, and by-products of oil refining. The method allows for the creation of a jet fuel composition with desirable properties, such as a freezing point below 30°C and a density between 730 and 772 kg/m3 at 15°C.
Overall, this patent presents a jet fuel composition that combines a petroleum derived component with a renewable component, resulting in a fuel with a low freezing point. The method described allows for the production of this composition by mixing the two components in specific proportions. The renewable component can be derived from various oils, making it a potentially sustainable and environmentally friendly option for jet fuel production.
