Microanalysis of Oil Shale of the Leningrad Field

Abstract:

The development of the fuel and energy complex entails a direct increase in energy consumption and the development of fundamentally new types of resources. In the near future, it is predicted that the role of solid fuels, including low-grade ones, will increase in the country's fuel and energy balance, which is primarily due to their large reserves. Russia ranks third after the USA and Brazil in the world for this mineral and, according to the latest estimates, potential reserves of this raw material are in the order of 700,288.85 million t. The article is devoted to the analysis of the chemical composition of oil shale of the Leningrad field. The point microanalysis of oil shale was carried out on the scanning electron microscope TESCAN, and IR spectra of various functional groups that are part of the shale were obtained and analyzed. It has been revealed that the functional groups C-C, C=O, CH₂, CH₃, SH are typical for the organic component of the oil shale of the Leningrad field. Carbonates, silicates and hydroxides mainly represent the mineral part with impurities represented by phosphates, sulfides and sulfates.
