Abstract

An improved diesel fuel based on a blend of biodiesel and ultra-low sulfur diesel fuel, particularly with a fuel additive containing a concentrate containing fuel borne catalyst (FBC). The catalyst will preferably comprise platinum and/or cerium and/or iron, and the ultra-low sulfur diesel fuel will preferably contain less than 10% aromatics. The biodiesel is typically employed in an amount of about 20% of the blend.

Claims

1. An improved diesel fuel blend comprising biodiesel and low aromatic content ultra-low sulfur diesel fuel.

2. A diesel fuel blend according to claim 1, which further includes a fuel borne catalyst (FBC) comprising platinum and/or iron, and/or cerium.

3. A diesel fuel blend according to claim 1, which comprises from 15 to 25% biodiesel.

4. A diesel fuel blend according to claim 1, wherein the low aromatic ultra-low sulfur diesel fuel component comprises less than 10% by volume aromatics.

5. A diesel fuel blend according to claim 1, wherein sulfur content is less than 0.0015%.

6. A diesel fuel blend according to claim 5, wherein the low aromatic ultra-low sulfur diesel fuel component comprises less than 10% by volume aromatics.

7. A diesel fuel blend according to claim 6, which further includes a fuel borne catalyst (FBC) comprising platinum and/or iron, and/or cerium.

8. A diesel fuel blend according to claim 1, which comprises from 15 to 25% biodiesel and the low aromatic ultra-low sulfur diesel fuel component comprises less than 10% by volume aromatics and a sulfur content of less than 0.0015% and the blend further includes a fuel borne catalyst (FBC) comprising platinum and/or iron, and/or cerium.

9. An improved diesel fuel blend comprising from 15 to 25% biodiesel and low aromatic content ultra-low sulfur diesel fuel comprising less than 10% by volume aromatics and a sulfur content of less than 0.0015%.

10. A diesel fuel blend according to claim 9, which further includes a fuel borne catalyst (FBC) comprising platinum and/or iron, and/or cerium.

11. A diesel fuel blend according to claim 10, wherein the FBC comprises platinum.

12. A diesel fuel blend according to claim 11, wherein the FBC comprises platinum and iron or cerium.
