Oil shale as a promising source of raw materials for advanced solid fossil fuel technologies

Information on the chemical nature and structure of the organic matter of oil shale from different deposits, the composition and distribution of mineral impurities in the volume of oil shale, and the elemental composition of the organic matter is considered in this article. It was found that the composition and properties of oil shale from different deposits are essentially different, and significant differences can also be observed within the limits of a deposit. Oil shale from some deposits contain trace impurity elements such as uranium, molybdenum, vanadium, and rhenium. In a number of cases, the concentrations of such impurities are increased, and their extraction can be of industrial interest.
