Removal of Sulfur from Hydrotreated Diesel Fuel

A simple and ecological two-stage method of removing sulfur from hydrotreated diesel fuel is described. In the first stage, the sulfur compounds left in the fuel are oxidized by hydrogen peroxide into sulfones, and in the second stage, the sulfones formed are extracted from the oxidation product by adsorption with silica gel. The diesel fuel obtained with this method satisfies the new European standards for sulfur content.
