Abstract

The present invention provides a composition comprising 10-40 mass! of C 8-30 linear alkanes, up to 20 mass % of C 7-20 aromatic hydrocarbons, at least 90 mass % of which are monoaromatic, and no more than 1 massl in total of oxygen containing compounds; wherein the total amount of C 8-30 alkanes in the composition is 50-95 mass % (and the total amount of C 8-30 alkanes, C 7-20 aromatic hydrocarbons and C 8-30 cycloalkanes is at least 95 massl; 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 10-40 mass % of C 8-30 linear alkanes, up to 20 mass % of C 7-20 aromatic hydrocarbons, at least 90 mass % of which are monoaromatic, and no more than 1 mass % in total of oxygen-containing compounds;
wherein the total amount of C 8-30 alkanes in the composition is 50-95 mass %, and the total amount of C 8-30 alkanes, C 7-20 aromatic hydrocarbons and C 8-30 cycloalkanes is at least 95 mass %;
wherein the composition comprises 45-80 mass % in total of C 8-30 cycloalkanes and C 8-30 branched alkanes; and
wherein the amounts are based on the mass of the composition.

2. A composition according to claim 1 , wherein the amount of C 8-30 linear alkanes is 20-40 mass %.

3. A composition according to claim 1 , wherein the amount of C 7-20 aromatic hydrocarbons is 0.1-15 mass %.

4. A composition according to claim 1 , which comprises 10-30 mass % of C 8-30 cycloalkanes.

5. A composition according to claim 1 , wherein the alkanes are C 9-23 alkanes.

6. A composition according to claim 1 , wherein the aromatic hydrocarbons are C 8-19 aromatic hydrocarbons.

7. A composition according to claim 1 , wherein the cycloalkanes are C 8-19 cycloalkanes.

8. A composition according to claim 1 , which comprises no more than 1 mass % of polyaromatic hydrocarbons.

9. A composition according to claim 1 , which comprises no more than 2 mass % of alkenes.

10. A composition according to claim 1 , which has a density of 795-830 kg/m 3 , as measured at 15° C. by the method of the EN ISO 12185 Standard.

11. A composition according to claim 1 , which has a lower heating value of 42.0-45.0 MJ/l, as measured using the method of the DIN 51900 Standard.

12. A composition according to claim 1 , which has a cetane number of at least 55, as measured using the method of the EN ISO 5165 Standard.

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

14. A fuel blend according to claim 13 , which contains the composition in an amount of 5-98 vol. % based on the volume of the blend.

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

16. A fuel blend according to claim 15 , wherein the petroleum-derived fuel is petrodiesel or kerosene.
