Claim Text:
1. A process of increasing the cetane number rating of a diesel oil feedstock, which process comprises the steps of: reacting a diesel fuel feedstock with ozone in the presence of an alcohol having two or more carbon atoms and at least one polar solvent different from said alcohol, thereby forming an ozonated diesel oil containing oxidized byproducts, wherein said alcohol and said polar solvent are employed in amounts totalling no more than about 10 vol.% of said feedstock; and separating said oxidized byproducts from said ozonated diesel oil to produce a diesel hydrocarbon product of increased cetane number rating relative to said feedstock; wherein said reacting of said feedstock with said ozone is carried out in the absence of an introduced oxidation catalyst.
