Diesel fuel composition with renewable and fossil fuel components
The granted patent US12037556B2 outlines a novel diesel fuel composition that integrates a hydrotreated renewable fuel component, a fossil fuel component, and a cetane number improver, specifically 2-ethylhexyl nitrate (2-EHN). The hydrotreated renewable fuel component is characterized by containing at least 80 wt-% of C15-C18 paraffins and an i-paraffin/n-paraffin ratio of at least 2.2 w/w. This renewable component can constitute between 5-90 vol-% of the overall diesel fuel composition, with specific claims indicating optimal ranges of 20-80 vol-% for enhanced performance. The composition notably excludes Fischer-Tropsch derived GTL fuel and can include various sources for the hydrotreated renewable fuel, such as hydrotreated vegetable oils, animal fats, and other plant-based oils.
Additionally, the patent details methods for producing and improving the cetane number of the diesel fuel composition. The methods involve mixing the hydrotreated renewable fuel component with the cetane number improver and fossil fuel component, maintaining the same specifications for the renewable component as in the composition claims. The amount of 2-EHN is specified to be between 100-1000 mg/kg, with claims suggesting a synergistic effect on cetane number enhancement when combined with the hydrotreated renewable fuel. The patent emphasizes the importance of low metal and phosphorus content in the renewable feedstock, ensuring the quality and performance of the resulting diesel fuel composition.
