Abstract: Due to the stringent requirements imposed on diesel fuel, the authors of this paper proposed a method to improve environmental and performance properties of diesel fuels. The paper presents the results of the study of naturally occurring glycerides as detergent-dispersant additives for diesel fuels. The authors have developed a rapid method of determining the effectiveness of antioxidant additives for fuels and lubricants, which is based on the measurement of the optical density of the sample during oxidation in the given experimental conditions. A rapid method of evaluating the detergent-dispersant properties of the fuel based on the determination of the changes of optical density during sedimentation of the pollutant model based on colloidal graphite of grade P-1 (1 wt. % strong). The results showed that the designed additive shows unique surfactant properties at concentrations of 0,001–0,005 % by weight. The additive improves both thermal-oxidative, detergent-dispersant and environmental performance of fuels, because additive molecules contain optimally combined functional groups which creates internal synergies.

Abstract: Protective liquids are applied at power plants to protect the hot water storage tanks against corrosion, as well as to prevent the saturation of deaerated water with oxygen from the environment and its evaporation. Viscosity properties and their dependence on temperature, concentration and molecular weight of the polymer, which is part of the protective liquid are studied. The possibility of using low molecular weight polymers instead of high polyisobutylene as a thickener component is considered. A technique to assess the status of the protective liquid during operation and determine the feasibility of increasing the lifetime of the battery is developed. Options for recycling the discharge protective liquids using adsorbents and selective solvents, as well as by their use as components of lubricants and conservation materials are considered.
