Claims20
A method of making a diesel fuel blend having enhanced cold properties, the method comprising:
- selecting a renewable fuel component and a mineral middle distillate fuel component having cloud points that differ by no more than a pre-selected temperature value;
- and
- blending the selected renewable fuel component and the selected mineral middle distillate fuel component in a ratio of amounts by volume of from 10:90 to 90:10 to form a diesel fuel blend that comprises 10-25 wt % n-paraffins in a C14-C20 range and an amount of iso-paraffins in a C14-C20 range such that a ratio of a sum of wt % amounts of the iso-paraffins in the C14-C20 range to a sum of wt % amounts of the n-paraffins in the C14-C20 range is less than 2.2 or is from 1.1 to 2.2.
A diesel fuel blend comprising:
- a renewable fuel component and a mineral middle distillate fuel component in which the renewable fuel component and mineral middle distillate fuel component are present in the diesel fuel blend in a ratio of amounts by volume of from 10:90 to 90:10;
- and
- the diesel fuel blend of the renewable fuel component and the mineral middle distillate fuel component having 10-25 wt % n-paraffins in a C14-C20 range and an amount of iso-paraffins in the C14-C20 range, such that a ratio of a sum of wt % amounts of the iso-paraffins in the C14-C20 range to a sum of wt % amounts of the n-paraffins in the C14-C20 range is less than 2.2 or is from 1.1 to 2.2.
A fuel blend comprising:
- a renewable fuel component and a mineral middle distillate fuel component in which the renewable fuel component and mineral middle distillate fuel component are present in the fuel blend in a ratio of amounts by volume of from 10:90 to 90:10;
- and
- the fuel blend of the renewable fuel component and the mineral middle distillate fuel component having 10-25 wt % n-paraffins in a C14-C20 range and an amount of iso-paraffins in the C14-C20 range, such that a ratio of a sum of wt % amounts of the iso-paraffins in the C14-C20 range to a sum of wt % amounts of the n-paraffins in the C14-C20 range is less than 2.2 or is from 1.1 to 2.2.
