Overview of domestic developments in the field of anti-wear additives for diesel fuels with low sulfur content

The analysis of the production volumes of diesel fuel with a low sulfur content in Russia is carried out. The need of diesel fuel manufacturers for anti-wear additives has been determined, taking into account the forecast of the Ministry of Economic Development until 2030. The domestic patents for anti-wear additives for diesel fuel are considered in detail and the best indicators of lubricity for each invention are given. The analysis of the dynamics of registration of domestic inventions on the method of obtaining anti-wear additives for the period from 2005 to 2020 is carried out. The article also shows the dependence of the lubricating ability of diesel fuels on the concentration of an anti-wear additive in the fuel and its composition. This review can be used by scientific and project groups when formulating a research hypothesis or for conducting a patent search. The article will be useful when preparing an application for intellectual property protection in this direction. In addition, the results of the review can be used in the formation of a feasibility study of an investment project and in the study of the domestic market of anti-wear additives for diesel fuel hydrotreating.
