Obtaining of Ashless Additives for Diesel Fuel Impoving the Lubricating,Anticorrosion and Protection Properties

Abstract

The production of “ultra pure” diesel fuels is connected with the deterioration of their certain performance characteristics. The lubricating properties of ultra pure diesel fuels are poor; their relative stability worsens; they tend to be corrosion-aggressive toward metal surfaces; and their electrophysical properties sharply deteriorate to increase the possibilities for accumulation of static-electric charge by transportation and feeding into vehicles (Tasheva, Petkov, and Ivanov, 2003 Tasheva, J., Petkov, P. and Ivanov, Sl. 2003. Contemporary trends in connection with the reduction of sulfur oxides at burning of fuels. Annual of University Prof. Dr. Assen Zlatarov, Bourgas, Bulgaria, XXXII(1): 150–155.  Google Scholar]; 2004 Tasheva, J., Petkov, P. and Ivanov, Sl. 2004.

These negative properties of the ultra pure diesel fuel are usually overcome by adding special substances to improve their lubricating properties, electric conductivity, and oxidation stability and to eliminate their corrosion aggressiveness.
