Abstract

A process for upgrading diesel oil to produce an upgraded diesel fuel comprising the steps of:
(a) reacting a diesel oil, having a boiling point at normal pressure of about 300°F to about 700°F, derived from a petroleum source with an oxidant selected from the group consisting of nitrogenous oxidizing agents and ozone wherein
(1) the reacting is to an extent sufficient to increase the cetane number of the diesel oil obtained in step (a) by at least 5 cetane numbers over the cetane number of the diesel oil feed to step (a), and
(2) (i) the reacting is such that when the oxidant is a nitrogeneous treating agent, the amount of oxi­ dant, equivalent on a 100% nitric acid basis, is about 10% or less by weight of the diesel oil feed to step (a); and
(ii) the reacting is such that when the oxidant is ozone, the amount of oxidant is sufficient to achieve an about 10% or greater reduction in the sulfur content of the reacted diesel oil obtained in step (a) over the diesel oil feed to step (a);
b) contactig the diesel oil from step (a) above with an extracting solvent, the extracting solvent
(1) having a dipole moment of about 2 or greater,
(2) being substantially immiscible with the diesel oil ob­ tained in step (a),
(3) being a nonhalogenated solvent, and
(4) excluding amines, which are reactive with the oxi­ dant,
or a mixture of such solvents or a water mixture of such sol­ vents comprising about 50% by weight or less water; and
(c) separating the diesel oil from step (b) above from the ex­ tracting solvent to recover upgraded diesel fuel.
