Abstract
The present disclosure provides a diesel fuel component produced from feedstock of biological origin and a method for producing the same. The present disclosure provides diesel fuel blends containing the diesel fuel component of biological origin and at least one additional diesel fuel.
Claims21
A method for combined production of aviation fuel and diesel fuel both of biological origin, the method comprising:
- providing feedstock of biological origin containing fatty acids and/or esters of fatty acids;
- and
- subjecting the feedstock to hydrotreatment and isomerization to obtain a paraffinic hydrocarbon intermediate;
- and
- fractionating said paraffinic hydrocarbon intermediate into at least two fractions,
- a lighter fraction fulfilling a specification ASTM D7566-20 Annex A2 for aviation fuel, and
- a heavier fraction fulfilling a specification EN 15940-18 for renewable diesel fuel;
- and
- adjusting a production capacity of the lighter fraction and a production capacity of the heavier fraction by selection of process conditions, and/or the isomerization process conditions, wherein yield of the lighter fraction is from 20 to 90 wt-% of a total weight of the formed fractions, and yield of the heavier fraction is from 10 to 80 wt-% of a total weight of the formed fraction;
- wherein a combined yield of the two fractions is at least 98 wt-% of the paraffinic hydrocarbon intermediate of biological origin.
7 more elements
A diesel fuel component of biological origin comprising:
- 0-5 wt-% of n-paraffins in C16-C20 range;
- and
- 90-97 wt-% isoparaffins in C16-C20 range, with from 21 wt-% to 45 wt-% of C17 paraffins and from 50 wt-% to 75 wt-% of C18 paraffins.
