A process for upgrading a diesel fuel, includes the steps of providing a diesel fuel feedstock; hydrogenating the feedstock at a pressure of less than about 600 psig so as to provide a hydrogenated product wherein a portion of the feedstock is converted to alkyl-naphthene-aromatic compounds; and sel

A process for upgrading a diesel fuel, includes the steps of providing a diesel fuel feedstock; hydrogenating the feedstock at a pressure of less than about 600 psig so as to provide a hydrogenated product wherein a portion of the feedstock is converted to alkyl-naphthene-aromatic compounds; and selectively oxidizing the hydrogenated product in the presence of a catalyst so as to convert the alkyl-naphthene-aromatic compounds to alkyl ketones. A catalyst and oxygen-containing Diesel fuel are also provided.

What is claimed is: 1. A catalyst for selective oxidation of alkyl-naphthene-aromatic compounds, the catalyst comprising between about 1% and about 5% wt of an element Me1 selected from the group consisting of oxides of Co, Ni, Fe, Cr, Cu and mixtures thereof; an oxide promoter Me2 in an amount between about 300 and about 10,000 wt ppm, and a nitrogen compound deposited on a support and being present in an amount between about 1% and about 4% wt, wherein the nitrogen compound is linked to both Me1 and Me2 to form a structure NMe1Me2. 2. The catalyst of claim 1 wherein the support is selected from the group consisting of carboxylic polymer, nitrogen-containing polymer, and nitrogen compound grafted on a silica support, and combinations thereof.
