Abstract
In a method of improving the quality of diesel fuel, an oxidizing gas is formed into sub-micron size bubbles which are dispersed into diesel fuel, after which the treated fuel is recovered. The oxidizing gas is preferably ozone and is utilized immediately upon its manufacture. By means of the method, sulfur is removed from the diesel fuel and the cetane rating thereof is increased.
Claims10
A method of removing sulfur compounds from diesel fuel comprising the steps of:
- providing an oxidizing gas;
- forming the oxidizing gas into sub-micron size bubbles;
- providing a flow of diesel fuel;
- dispersing the sub-micron size bubbles of oxidizing gas into the flowing diesel fuel thereby oxidizing the sulfur compounds initially contained within the diesel fuel into sulfoxides and/or sulfones;
- removing the sulfoxides and sulfones from the diesel fuel;
- and
- recovering the treated diesel fuel.

A method of removing sulfur compounds from petroleum distillates comprising the steps of:
- providing an oxidizing gas;
- forming the oxidizing gas into sub-micron size bubbles;
- providing a flow of a petroleum distillate;
- dispersing the sub-micron size bubbles of oxidizing gas into the flowing petroleum distillate thereby oxidizing the sulfur compounds initially contained within the petroleum distillate into sulfoxides and/or sulfones;
- removing the sulfoxides and sulfones from the petroleum distillate;
- and
- recovering the treated petroleum distillate.
