Abstract

The present invention provides a fuel comprising a renewable middle distillate composition obtainable by hydrodeoxygenation of a feedstock comprising levulinic acid dimers/oligomers and fractionated distillation. The renewable middle distillate composition contains less than 10.0 wt.-% aromatics.

Claims

1. A fuel comprising:

a renewable middle distillate composition which includes a fractionally distilled hydrodeoxygenation product of a hydrodeoxygenated feedstock of dimers/oligomers of levulinic acid and/or dimers/oligomers of derivatives of levulinic acid, wherein the renewable middle distillate composition contains less than 10.0 wt.-% aromatics, as determined in accordance with ASTM D2425,

wherein the renewable middle distillate composition contains from 50 wt.-% to 80 wt.-% cycloparaffins having 8 to 15 carbon atoms, wherein 50 wt.-% or more of the cycloparaffins have 8 to 10 carbon atoms,

wherein the freezing point of the renewable middle distillate composition is −

70°

C. or lower, and

wherein the boiling point of the middle distillate composition is in the range of 150°

C. to 370°

C.

2. The fuel according to claim 1, wherein the renewable middle distillate composition contains at most 9.5 wt.-% of aromatics, as determined in accordance with ASTM D2425.

3. The fuel according to claim 1, wherein the fuel further contains fossil fuel, HEFA (hydroprocessed ester and fatty acids) fuel and/or HVO (hydrotreated vegetable oil) fuel.

4. The fuel according to claim 1, wherein the BOCLE lubricity of the renewable middle distillate composition is 0.75 mm or less, as determined in accordance with ASTM D5001-10 (2014).

5. The fuel according to claim 1, wherein the renewable middle distillate composition obtained by hydrodeoxygenation of dimers/oligomers of levulinic acid and/or dimers/oligomers of derivatives of levulinic acid followed by fractionated distillation, is an aviation fuel or aviation fuel component.

6. The fuel according to claim 1, wherein the renewable middle distillate composition contains at most 3.0 wt.-% of aromatics, as determined in accordance with ASTM D2425.

7. The fuel according to claim 2, wherein the freezing point of the renewable middle distillate composition is −

95 C or lower.

8. The fuel according to claim 2, wherein the renewable middle distillate composition contains at least 55 wt.-% of cycloparaffins, as determined in accordance with ASTM D2425.

9. The fuel according to claim 2, wherein the renewable middle distillate composition contains at most 70 wt.-% of cycloparaffins, as determined in accordance with ASTM D2425.

10. The fuel according to claim 2, wherein the BOCLE lubricity of the renewable middle distillate composition is 0.67 mm or less, as determined in accordance with ASTM D5001-10 (2014).
