Документ Modern Trends in The Use of Additives in Fuel and Oil Materials (Overview)(2022) Trotsenko, Oleksandr; Grigorov, Andrey; Nazarov, Valerii; Nahliuk, MikhailDomestic and foreign literature data were reviewed on the conditions and features of additives use, their required content in fuel and oil materials, and the study of their characteristics in order to systematize data on additives used to improve the operational properties of fuel and oil materials. The use of additives in the composition of fuel and oil materials can significantly increase the level of their operational properties, without serious production costs associated with deep cleaning and preliminary preparation of raw products, compounding of raw products, technical re-equipment of production, etc. A list of additives was offered to fuel and oil materials used in the world practice of their production and application, added with dyes. These additives should be included in the main package of production branded premium fuel and oil materials, create their classification, simplify the procedure for identifying different batches, simplify the procedure for transportation, storage and distribution of fuel and oil materials. At the same time, among all the variety of dyes that are currently used for coloring to fuel and oil materials, the most appropriate is to use those that carry out multifunctional properties. These properties, depending on the type of materials, along with the color, can be density, detonation resistance, anti-corrosion. This approach, on one hand, will allow to balance the amount and properties of additives included in the overall package, on the other hand - will reduce production cost of the fuel and oil materials.Документ Technology for Producing Components of Technological and Boiler Fuels from Polymer Raw Materials(2021) Shevchenko, Kyrylo; Grigorov, A. B.; Ponomarenko, Vitaliy; Nahliuk, Mikhail; Bondarenko, Oleksandr; Stetsiuk, Yevhen; Matukhno, VasylThe article presents a schematic diagram of obtaining the components of technological and boiler fuels from polymer raw materials represented by materials from low and high pressure polyethylene, polypropylene and polystyrene. This scheme is based on the process of non-catalytic thermal destruction of raw materials in a batch reactor and consists of a section for preparation of raw materials, a section for thermal destruction as well as the fractionation of the resulting products. The given scheme on an industrial scale, depending on the properties of the raw material, makes it possible to obtain 10-20% (mass) of the fraction - 200°C, 30-50% (mass) of the 200-360°C fraction and 20-30% (mass.) fractions (> 360°C). Among the by-products, 3.0-5.0% (mass) light hydrocarbon gases (0.5-1.0 mass %) and the coke residue are formed. According to their properties, the obtained liquid products can be used as components for the production of process and a boiler fuel or as additives to improve the low-temperature properties of commercial fuels.Документ Selection of a dispersion medium for recycling plastic greases according to fire and explosion indicators(2020) Grigorov, Andrey; Sytnik, Alexey; Ponomarenko, Natalia; Neustroieva, Gelena; Nahliuk, MikhailThe article presents the results of determining fire and explosion hazard indicators for used lubricants, which are supposed to be used as a dispersion medium in the production of recycling plastic greases. Having determined the flash point of the oils, it is possible to calculate the values of the ignition temperature and self-ignition according to linear regression equations, with an error of up to 2 °C. The flash point can be a criterion when choosing raw materials and layout of the technological scheme for the production of recycling plastic greases.
