Abstract
A diesel fuel composition as disclosed includes a fossil diesel component, a fatty acid methyl esters component, and a hydrotreated renewable paraffinic diesel component. A method is disclosed for producing the diesel composition and use thereof. Use of the hydrotreated renewable paraffinic diesel component as an oxidation stability improver is further disclosed.
Claims21
A diesel fuel composition comprising:
- a. a fossil diesel component at least 20 vol-% of a total diesel fuel composition volume, the fossil diesel component having a boiling point range within a temperature range 150-400° C. measured according to EN-ISO-3405:2011;
- b. a fatty acid methyl esters (FAME) component 2-10 vol-% of the total diesel fuel composition volume;
- c. a hydrotreated renewable paraffinic diesel component 30-70 vol-% of the total diesel fuel composition volume, wherein the hydrotreated renewable paraffinic diesel component containing at least 70 wt-% paraffins in a range of carbon number C15-C18 of a total weight of paraffins in the hydrotreated renewable paraffinic diesel component;
- and
- d. antioxidant 10-1000 ppm by weight of the diesel fuel composition weight;
- wherein a total amount of the fossil diesel component, the FAME component, and the hydrotreated renewable paraffinic diesel component is at least 99 vol-% of the total diesel fuel composition volume.
A method for producing a diesel fuel composition the method comprising:
- providing a fossil diesel component;
- providing a hydrotreated renewable paraffinic diesel component;
- providing a fatty acid methyl esters (FAME) component;
- providing an antioxidant;
- and
- mixing the fossil diesel component, the hydrotreated renewable paraffinic diesel component, the FAME component, and the antioxidant with each other to form a diesel fuel composition containing, based on a total diesel composition volume, at least 20 vol-% fossil diesel component, the fossil diesel component having a boiling point range within a temperature range 150-400° C. measured according to EN-ISO-3405:2011;
- 30-70 vol-% hydrotreated renewable paraffinic diesel component, wherein the hydrotreated renewable paraffinic diesel component contains at least 70 wt-% paraffins in a range of carbon number C15-C18 of the total weight of paraffins in the hydrotreated renewable paraffinic diesel component;
- 2 vol-%-10 vol-% FAME component;
- and antioxidant 10-1000 ppm by weight of a diesel fuel composition weight.
(canceled)
A method for improving oxidation stability of a fuel composition containing a fossil diesel component and a fatty acid methyl esters (FAME) component a hydrotreated renewable paraffinic diesel component, the method comprising:
- adding a hydrotreated renewable paraffinic diesel component to the fuel composition to form a combined fuel composition containing 30-70 vol-% renewable paraffinic diesel component of a total combined fuel composition volume.
