Abstract

A fuel composition comprises humins and at least one organic oxygenated solvent which has an apparent viscosity of at most 1.5 Pa·s at 100° C. at a shear rate of 30 s −1 . Humins are produced by the dehydration of carbohydrates. The organic oxygenated solvent is selected from the group consisting of alcohols, ethers, aldehydes, ketones, acids, esters, which may be aromatic, cycloaliphatic and aliphatic, and mixtures thereof. The fuel compositions can be used as marine fuel.

First claim

2. Fuel composition according to claim 1 , which has an apparent viscosity in the range of 0.005 to 0.1 Pa·s, preferably in the range of 0.01 to 0.08 Pa·s.

3. Fuel composition according to claim 1 , comprising the humins in an amount ranging from 1 to 99% wt, based on the weight of the fuel composition.

4. Fuel composition according to claim 1 , wherein the humins are produced by the dehydration of carbohydrates.

5. Fuel composition according to claim 1 , comprising the organic oxygenated solvent in an amount ranging from 1 to 99% wt, based on the weight of the fuel composition.

6. Fuel composition according to claim 1 , wherein the organic oxygenated solvent is selected from the group consisting of alcohols, ethers, aldehydes, ketones, acids, esters, which may be aromatic, cycloaliphatic and aliphatic, and mixtures thereof.

7. Fuel composition according to claim 1 , wherein the organic oxygenated solvent is selected from the group consisting of mono-alcohols having from 1 to 10 carbon atoms, ethers having from 4 to 10 carbon atoms, and C 1 -C 6 esters of carboxylic acids, containing from 1 to 6 carbon atoms, and mixtures thereof.

8. Fuel composition according to claim 7 , wherein the organic oxygenated solvent has been selected from C 1 -C 6 alkyl esters of levulinic acid.

9. A method of use of a fuel composition, wherein the fuel composition according to claim 1 is used as a marine fuel.

10. Residual fuel oil composition comprising a residual fuel oil and a fuel composition according to claim 1 .

11. Residual fuel oil composition according to claim 10 , wherein the residual fuel oil is present in the range of 9 to 95% wt, humins are present in an amount in the range of 1 to 90% wt, and the organic oxygenated solvent is present in an amount in the range of 0.1 to 20% wt, the weight percentages being based on the weight of the residual fuel oil, the humins and the organic oxygenated solvent.

12. Residual fuel oil composition comprising a mixture of residual fuel oil and humins, wherein the residual fuel oil is a liquid residual fuel oil which comprises at least 1% of humins by weight of the mixture and the mixture has an apparent viscosity of at most 1.5 Pa·s at 100° C. at a shear rate of 30 s −1 .

13. Residual fuel oil composition according to claim 12 , which has a kinematic viscosity in the range of 5 to 50 mm 2 /s at 100° C., determined in accordance with ASTM D445.

15. The method according to claim 14 , comprising adding a residual fuel oil to the mixture.

16. Fuel composition according to claim 2 , comprising the humins in an amount ranging from 1 to 99% wt, based on the weight of the fuel composition.

17. Fuel composition according to claim 2 , wherein the humins are been produced by the dehydration of carbohydrates.

18. Residual fuel oil according to claim 12 , wherein the residual fuel oil is present in the range of 9 to 95% wt, humins are present in an amount in the range of 1 to 90% wt, and the organic oxygenated solvent is present in an amount in the range of 0.1 to 20% wt, the weight percentages being based on the weight of the residual fuel oil, the humins and the organic oxygenated solvent.
