Shevchenko K. Technology of components of motor and boiler fuels obtained from secondary polymer raw materials

The dissertation is aimed at developing the technology of obtaining components of motor and boiler fuels. The object of research is the process of obtaining components of motor and boiler fuels by thermal destruction of polyethylene and polypropylene secondary raw materials. The subject of research is the influence of chemical composition and temperature limits of boiling, the obtained components on the properties of compounded commercial fuel. The dissertation solves an important scientific and practical problem related to the expansion of raw materials and improving the production of motor and boiler fuels that meet environmental safety standards adopted in the European Union. For the first time in the dissertation: - theoretically substantiated and experimentally confirmed the effect of the hydrocarbon composition of liquid products of thermal destruction of secondary polyolefin raw materials - fractions with a boiling range of 200-300 ° C on their chemical stability; - hypothesized the influence of the rate of thermal destruction (k, g / s) of polyolefin raw materials on the mass yield and physico-chemical quality indicators of fuel fractions; - graphical schemes of limiting the content of the obtained component are presented, according to which it is necessary to determine the limits of boiling of narrow fuel fractions, which should be used in compounded fuel; - an algorithm for the selection of secondary raw materials for its technological processing into components of motor and boiler fuels is proposed, which is based on determining production costs at each stage of the process and allows calculating the total cost of the final product.
