lubricity

The article deals with the determination of hydrodynamic parameters necessary to conduct the desulfurization process of straight-run kerosene (SRKF) and straight-run diesel fractions (SRDF) via oxidation of sulfuric organic compounds, followed by the removal of oxidation products. The established parameters which are characterized by the linear rate of the oxidant (air) movement and the dummy contact time between the oxidant and the feedstock allow the process to be carried out without stirring.

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.
