Документ Recycling of Polymer Waste into Plastic Lubricants(2022) Grigorov, Andrey; Sinkevich, Irina; Ponomarenko, Natalia; Bondarenko, Oleksandr; Usachov, Dmytro; Matukhno, Vasyl; Shevchuk, OleksandrA technology for the production of greases from polymeric household waste has been proposed, including the stage of boiling the polymer in a solvent, which is used as a used motor oil SAE10W-40. In the production of greases using this technology, a significant amount of used polymer products is utilized, while the share of waste from low-pressure polyethylene and polypropylene (PP) is, respectively, 20-50% of the mass and 50-75% of the mass. This approach makes it possible to significantly expand the raw material base of the specified technological process and, due to the involvement of relatively cheap raw materials, significantly reduce the cost of finished products. The results of the study of the adhesive properties of the obtained lubricants allow us to give the following recommendations: for lubricants based on low-pressure polyethylene with a polymer: oil ratio of 1: 1, the rational rotation speed was no more than 2850 rpm, with a ratio of 1: 3 - about 3950 rpm and with a ratio of 1 : 5 - up to 5300 rpm; rational rotation speed for lubricants based on PP at a polymer: oil ratio of 1: 1 does not exceed 3600 rpm, at a ratio of 2: 1- 4900 rpm and at a ratio of 3: 1 - 6000 rpm.Документ Possibility of producing plastic lubricants by thermal destruction of solid domestic wastes(2020) Grigorov, Andrey; Zelenskii, Oleg; Sytnik, Alexey; Nahliuk, IvanThe results of non-catalytic thermal destructive processing of solid domestic waste at atmospheric pressure and temperature of 360°C, which are represented by products of low pressure polyethylene, are presented. The products obtained during degradation can be divided into fuel products (gas, liquid hydrocarbon fraction, coke residue) and fraction (with the beginning of boiling in the temperature range 200-320°C), which can be used in the production of greases. After the heat treatment and cooling of these fractions, a product with properties similar to NYCO 65 VASELINE (Technical petrolatum (GREASE)) can be obtained. For the production of plastic lubricants with other properties and a large temperature interval of application, a scheme has been proposed, it provides for the addition of fillers and additives of different functional purpose to the lubricant obtained.Документ Production of boiler and furnace fuels from domestic wastes (polyethylene items)(2018) Grigorov, Andrey; Mardupenko, Aleksey; Sinkevich, Irina; Tulskaya, Alena; Zelenskyi, OlegThe results of the thermal destruction of solid domestic waste (which are polyethylene items) were presented for batch-type laboratory equipment. According to the modern requirements of EU for the amount of sulphur in fuel and boiler fuels, polyethylene items are a valuable source for pro-duction of these fuels. During atmospheric heating of the raw material in reactor the intensive destruction of polyethylene can be observed in the range of temperature 560–580 K. It has been defined the composition of products of polyethylene thermal destruction: 95 % (mass.) of liquid hydrocarbons, 4,5 % (mass.) of light hydrocarbon gases and 0,5 % (mass.) of coke. Fractionation of liquid hydrocarbons allows to separate 15 % (mass) of fraction 340-488 K, 14 % of fraction 406-518 K, 43 % of fraction 438-546 K and 27 % of residue (>623ºС fractions). Liquid products can be applied for production of boiler and furnace fuels independently and in a mixture with the petroleum processing products in different ratio.
