Abstract
A method and process to remove sulfur compounds from a real fuel product of straight-run diesel (SRD) by the action of ozone bubbling and tert-butyl hydroperoxide (t-BUOOH) under normal laboratory conditions is disclosed. Slight desulfurization is taken place after ozone bubbling process which may be assigned to a removal of sulfur compounds in a gaseous form (SO). Most of the organically bound sulfur and/or elemental sulfur and hydrogen sulfide still exist in the ozonized samples. Sulfur removal from SRD samples was achieved by combining ozone bubbling with extraction by using different solvents to remove the oxidized sulfur compound (polar) from ozonized samples. This method provides a considerable level of total sulfur reduction where the reduction of sulfur reaches 93%.
