Abstract
Emissions of polynuclear aromatic hydrocarbons (PAHs) from diesel engines may be reduced by blending a renewable hydrocarbon distillate with a base diesel fuel. The base diesel may be a fossil diesel fuel, a Fischer-Tropsch diesel fuel as well as a hydroprocessed biodiesel fuel or a combination thereof. The renewable hydrocarbon distillate is a fraction from hydrotreated bio-oil having a boiling point between from about 320° F. to about 700° F.
