Abstract
The invention provides a method for increasing the cetane number of a low hydrogen content, highly aromatic distillate fuel by subjecting it to catalytic partial oxidation. Catalysts employed include transition metal oxides alone or in conjuction with alkali metal or alkaline earth metal compounds. Partial oxidation in accordance with the method of this invention not only results in cetane number improvement, but also allows a higher concentration of aromatic substituents in the fuel blend.
