Abstract
A diesel fuel composition containing a renewable paraffinic diesel component and di-GTBE. A method for producing the diesel fuel composition and use thereof. Use of di-GTBE as a lubricity improver for fuels is further disclosed.
Claims20
A diesel fuel composition comprising:
- a. a renewable paraffinic diesel component at most 95 vol-% of a total diesel fuel composition volume, the renewable paraffinic diesel component containing paraffins in a range of carbon number C15-C18 at least 70 wt-% of a total weight of paraffins in the renewable paraffinic diesel component;
- and
- b. di-glycerol tert-butyl ether (di-GTBE) at least 5 vol-% of the total diesel fuel composition volume.
A method for producing a diesel fuel composition, comprising:
- providing a renewable paraffinic diesel component produced by;
- i. providing a feedstock originating from renewable sources, the feedstock containing fatty acids, or triglycerides, or both;
- ii. subjecting the renewable feedstock to hydrotreatment, to produce n-paraffins;
- and optionally
- iii. subjecting at least a portion of the n-paraffins from step ii) to an isomerization treatment to produce i-paraffins;
- providing di-glycerol tert-butyl ether (di-GTBE);
- and
- mixing the renewable paraffinic diesel component with the di-GTBE to form a diesel fuel composition containing di-GTBE at least 5 vol-% and renewable paraffinic diesel component at most 95 vol-% of the total diesel fuel composition volume.
5 more elements
A method for improving lubricity of a fuel using di-glycerol tert-butyl ether (di-GTBE), the method comprising:
- providing a fuel;
- and
- adding di-GTBE to the fuel.
