Formulation and method of preparation of energy fortified diesel fuel

摘要

An energy fortified diesel fuel is provided containing a hydrocarbon additive wherein greater than 50% vaporizes at or above about 650 DEG F. and diesel fuel of which about 90% of the diesel fuel vaporizes at or below about 640 DEG F. or about 95% of the diesel fuel vaporizes at or below about 698 DEG F. This energy fortified diesel fuel is made by distilling a heavy hydrocarbon fraction such as slurry oil or heavy cycle oil obtained from an FCC unit or a heavy hydrocarbon fraction obtained from a steam cracker unit at a temperature of between about 500 and 750 DEG F. and at a pressure of between about 1 mm Hg and 10 psig to remove contaminants, removing distillate from this distillation, and mixing the distillate with diesel fuel, wherein about 90% of the diesel fuel vaporizes at or below about 640 DEG F. or about 95% of the diesel fuel vaporizes at or below about 698 DEG F., to form an energy fortified diesel fuel. This energy fortified diesel fuel is a desirable fuel for off highway heavy duty and "very" heavy duty compression ignition engines.
