Desulfurization and Denitrogenation Process for Light Oils Based on Chemical Oxidation followed by Liquid−Liquid Extraction

A desulfurization and denitrogenation process for light oils has been investigated based on the chemical oxidation of sulfur- and nitrogen-containing compounds using hydrogen peroxide and acetic acid as oxidizing agent. Sulfur and nitrogen compounds, when dissolved in n-tetradecane and xylene, were oxidized under moderate conditions and were removed successfully. By use of this basic process, although nitrogen content of actual light oils was reduced to
