Fuel composition for a diesel engine
The invention is directed to a fuel composition for diesel engines. The fuel composition comprises 0.1-99% by weight of a component or a mixture of components produced from biological raw material originating from plants and/or animals and/or fish. The fuel composition comprises 0-20% of components containing oxygen. Both components are mixed with diesel components based on crude oil and/or fractions from Fischer-Tropsch process.
1. A composition for diesel fuel, wherein said composition consists of at least one component produced by a process comprising:
providing at least one biological raw material originating from animals, wherein said biological raw material contains fatty acids and/or fatty acid esters;
hydrogenating and decomposing said fatty acids and/or fatty acid esters to form hydrocarbons;
isomerizing said hydrocarbons to form isoparaffins; and
wherein said composition is free of aromates and has a cetane number higher than 60.
2. The composition according to claim 1 , wherein said biological raw material is selected from fats, oils, and mixtures thereof.
3. The composition according to claim 1 , wherein said biological raw material is selected from animal-based fats; fats contained in milk; recycled fats of the food industry and mixtures thereof.
4. The composition according to claim 1 having a turbidity point lower than −30° C.
5. The composition according to claim 1 having a density less than diesel.
6. A composition for diesel fuel, wherein said composition consists of at least one component produced by a process comprising:
providing at least one biological raw material originating from animals or from animals in combination with plants and/or fish, wherein said biological raw material contains fatty acids and/or fatty acid esters;
hydrogenating and decomposing said fatty acids and/or fatty acid esters to form hydrocarbons; and
isomerizing said hydrocarbons to form isoparaffins;
wherein said composition is free of aromates.
7. The composition according to claim 6 , wherein said biological raw material is selected from fats, oils, and mixtures thereof.
8. The composition according to claim 6 , wherein said biological raw material is selected from animal-based fats; fats contained in milk; recycled fats of the food industry; wood-based fats or oils; non-wood, plant-based fats or oils; fats contained in plants bred by means of gene manipulation; fish oils; and mixtures thereof.
9. The composition according to claim 6 , wherein said biological raw material originates from a combination of animals and plants.
10. The composition according to claim 6 having a cetane number higher than 60.
11. The composition according to claim 6 having a turbidity point lower than −30° C.
12. The composition according to claim 6 having a density less than diesel.
13. A composition for diesel fuel, wherein said composition consists of:
a) at least one component produced by a process comprising:
providing at least one biological raw material originating from animals or from animals in combination with plants and/or fish, wherein said biological raw material contains fatty acids and/or fatty acid esters;
hydrogenating and decomposing said fatty acids and/or fatty acid esters to form hydrocarbons; and
isomerizing said hydrocarbons to form isoparaffins;
b) at least one component selected from aliphatic alcohols, ethers, fatty acid esters, water, and mixtures thereof;
wherein said composition is free of aromates.
14. The composition according to claim 13 , wherein said biological raw material is selected from fats, oils, and mixtures thereof.
15. The composition according to claim 13 , wherein said biological raw material is selected from animal-based fats; fats contained in milk; recycled fats of the food industry; wood-based fats or oils; non-wood, plant-based fats or oils; fats contained in plants bred by means of gene manipulation; fish oils; and mixtures thereof.
16. The composition according to claim 13 , wherein said biological raw material originates from a combination of animals and plants.
17. The composition according to claim 13 , wherein said biological raw material originates from a combination of animals, plants, and fish.
18. The composition according to claim 13 , wherein said (a) component has a cetane number higher than 60.
19. The composition according to claim 13 , wherein said (a) component has a turbidity point lower than −30° C.
20. The composition according to claim 13 , wherein said (a) component has a density less than diesel.
