Influence of the parameters of organic compounds adsorption on iron surface and the operating efficiency of wear-preventive additives to diesel fuels
The article describes the calculations of adsorption activity of different organic com-pounds to metal iron, performed by quantum chemistry and molecular dynamics methods, aimed at consequent selection of the active substance for production of the wear-preventive additive for deep-hydrotreated diesel fuel. It is found out that the diesters of oxalic acid with maximum design values of adsorption energy in the test experiments according to GOST 12156-1-2006 in fuel composition at the rate of 1% give minimum values of the wear spot diameter (186–264 mm) at the norm not above 460 mm.
