Abstract (English):
The paper presents the results of obtaining diesel fuel with improved characteristics using the developed method. The essence of the developed method is that the Hydro Plus diesel fuel is produced in a diesel fuel hydrotreating unit by combining diesel fractions from atmospheric-tubular units and light gas oils from vacuum units, a catalytic cracking unit, and a delayed coking unit and hydrotreating the resulting mixture with hydrogen-containing gas formed in a catalytic reforming unit. After hydrotreating, technical kerosene (up to 15%) produced in atmospheric-tubular units is added to its composition. In the proposed method for increasing the volume and improving the performance properties of hydrotreated diesel fuel (ecologically clean fuel), the following additives are proposed to be used to level and improve some technical indicators of this fuel: Kerofluks 6100 - this additive prevents the formation of crystals of interconnected hydrocarbons of the limiting series, resulting in a decrease in the maximum filtration temperature and the freezing temperature of the resulting diesel fuel; Kerofluks 3614 - this additive acts as a paraffin dispersant by reducing the size of the resulting crystals of paraffin alkanes, as well as due to electrostatic forces; Kerokorr LA99C - this additive increases the lubricating properties of diesel fuel, resulting in increased wear resistance and service life of the engine. In addition, adding a certain amount of technical kerosene to the resulting environmentally friendly diesel fuel leads to an overall increase in the volume of the product produced, as well as an improvement in some performance characteristics of the final product (flash point and freezing point).
