Application of non-catalytic oxidative desulphurization process for obtaining diesel fuels with improved lubricity

Abstract

The fractions of diesel oil have been desulphurized via air oxidation without the catalysts in the presence of water. The products of sulphuric compounds oxidation were extracted by adsorption or joint adsorption and rectification. The samples of desulphurized diesel oil have been analyzed in accordance with reference documents after their treatment by alkali. The lubricity of the raw materials (straight-run diesel oil and hydrogenised fuel), desulphurized straight-run diesel oil (DSDO), hydrogenised fuel with DSDO additives and two samples of the fraction 553-623 K purified in the presence of water and without it has been determined. © Pysh'yev S., 2012.
