Abstract
Disclosed herein are methods for manufacturing and using a diesel fuel composition comprising a cetane number improver, a fossil fuel component, and a hydrotreated renewable fuel component manufactured by hydrotreating and isomerising renewable raw material.
Claims20
A diesel fuel composition comprising:
- a hydrotreated renewable fuel component;
- a fossil fuel component;
- and
- a cetane number improver,
- wherein the fossil fuel component is a fossil middle distillate, and
- wherein the hydrotreated renewable fuel component constitutes 5-90 vol-% of the diesel fuel composition.
3 more elements
A method for improving a diesel fuel composition's cold properties, the method comprising:
- catalytically hydrotreating a renewable raw material comprising fatty acids, triglycerides, fatty acid esters, or combinations thereof into n-paraffins;
- catalytically isomerising the n-paraffins into branched chain paraffins to obtain a hydrotreated renewable fuel component;
- and
- mixing a cetane number improver and a fossil fuel component with the hydrotreated renewable fuel component,
- wherein the hydrotreated renewable fuel component produced from the catalytic isomerization contains an i-paraffin/n-paraffin ratio of at least 2.2 w/w.
