Abstract (English):
Currently, the obtaining of environmentally friendly fuels is of scientific and practical interest, since the main pollutants of the environment are motor fuels, the combustion of which releases a large number of hazardous pollutants into the atmosphere along with exhaust gases. The article considers the process of extraction dearomatization of diesel fuel using ionic liquid morpholinformate as an extractant, then subsequent involvement in the composition of the obtained dearomatized diesel fuel as an oxygen-containing additive 5-10% methyl esters of natural petroleum acids. It was found that the yield of dearomatized diesel fuel in the process of extraction dearomatization is 84.8%. As a result, the content of sulfur and aromatic hydrocarbons in the dearomatized diesel fuel composition is reduced to 0,0216% and 0,8%, respectively. Then, 5-10% compounds based on dearomatized diesel fuel and methyl esters of natural petroleum acids were made and their quality indicators were studied. It was found that adding the latter to the dearomatized diesel fuel composition has a favorable effect on the quality indicators of the obtained compounds. Thus, the sulfur content in their composition decreases and amounts to 0,0205-0,0187%, and the aromatic hydrocarbon content is 0,6-0,3%. At the same time, the antiwear properties of the obtained 5-10% compounds were studied and it was found that their wear scar diameter decreases and amounts to 0,457 and 0,423 mm, respectively. In addition, the composition of exhaust gases during combustion of the original diesel fuel, dearomatized diesel fuel and dearomatized diesel fuel containing 10% methyl esters of natural petroleum acids was studied and a decrease in the content of carbon oxides, sulfur and nitrogen in the exhaust gases was found.
