Abstract

The present invention provides a composition comprising 8-30 mass % of C 4-12 linear alkanes, 5-50 mass % of C 4-12 branched alkanes, 25-60 mass % of C 5-12 cycloalkanes, 1-25 mass of C 6-12 aromatic hydrocarbons, no more than 1 mass % of alkenes, and no more than 0.5 mass % in total of oxygen-containing compounds; wherein the total amount of C 4-12 alkanes is 40-80 mass %, and the total amount of C 4-12 alkanes, C 5-12 cycloalkanes and C 6-12 aromatic hydrocarbons is at least 95 mass %; and wherein the amounts are based on the mass of the composition. Also provided is a method for producing the composition comprising the step of hydroprocessing a biological feedstock using a catalyst and the step of fractionating the product of the hydroprocessing step.

First claim

The invention claimed is:

1. A composition comprising 8-30 mass % of C 4-12 linear alkanes, 20-50 mass % of C 4-12 branched alkanes, 25-60 mass % of C 5-12 cycloalkanes, 1-25 mass of C 6-12 aromatic hydrocarbons, no more than 1 mass % of alkenes, and no more than 0.5 mass % in total of oxygen-containing compounds;
wherein the total amount of C 4-12 alkanes is 40-70 mass %, and the total amount of C 4-12 alkanes, C 5-12 cycloalkanes and C 6-12 aromatic hydrocarbons is at least 95 mass %; and
wherein the amounts are based on the mass of the composition.

2. A composition according to claim 1 , wherein the amount of C 4-12 linear alkanes is 10-20 mass %.

3. A composition according to claim 1 , wherein the amount of C 4-12 branched alkanes is 20-40 mass %.

4. A composition according to claim 1 , wherein the amount of C 5-12 cycloalkanes is 30-50 mass %.

5. A composition according to claim 1 , wherein the amount of C 6-12 aromatic hydrocarbons is 2-15 mass %.

6. A composition according to claim 1 , wherein the linear alkanes are C 5-10 linear alkanes.

7. A composition according to claim 1 , wherein the branched alkanes are C 5-11 branched alkanes.

8. A composition according to claim 1 , wherein the cycloalkanes are C 6-10 cycloalkanes.

9. A composition according to claim 1 , wherein the aromatic hydrocarbons are C 6-10 aromatic hydrocarbons.

10. A fuel blend comprising a composition as defined in claim 1 .

11. A fuel blend according to claim 10 , wherein the amount of the composition is 2-85 vol. % based on the volume of the fuel blend.

12. A fuel blend according to claim 11 , wherein the amount of the composition is 5-25 vol. %.

13. A fuel blend according to claim 11 , which further comprises a petroleum-derived fuel.

14. A fuel blend according to claim 13 , wherein the petroleum-derived fuel is petroleum naphtha and/or petroleum gasoline.

15. A fuel blend according to claim 10 , which further comprises ethanol.

16. A fuel blend according to claim 15 , wherein the amount of ethanol is up to 85 vol. % based on the volume of the fuel blend.

17. A fuel blend according to claim 16 , wherein the amount of ethanol is 75-85 vol %.

18. A fuel blend according to claim 10 , which further comprises at least one of butane, isobutanol and ethyl tert-butyl ether.

19. A fuel blend according to claim 10 , which comprises 2-25 vol. % of the composition, 75-85 vol. % of ethanol, 1-5 vol. % of ether compounds containing five or more carbon atoms, and up to 2 vol. % of C 3-8 higher alcohols, the amount of butane contained in the fuel blend being 2-10 vol. %.

20. The composition according to claim 1 , wherein the density of the composition is 720-775 kg/m 3 as measured at 15° C. by EN ISO 12185 method.
