“…Abaturov et al 30 describe the effect of low-temperature (250 °C) and high-temperature (350 °C) thermal oxidation of shale tar on the content of anisotropic elements in the structure of the shale coke. It was found that thermo-oxidation of shale oil at 350 °C leads to the formation of α-fractions in the reaction medium (HI-TI, heptane-insoluble and toluene-insoluble) and increases the softening temperature and thermo-oxidation at 250 °C leads to the removal of elements with a microstructure score of more than 3 from the coke microstructure.…”

This paper presents the results of studies on the production of coke at excess pressures of 0.15, 0.25, and 0.35 MPa with delayed coking of shale tar obtained by pyrolysis of oil shale in the Baltic Basin. To assess the quality of the resulting coke, properties such as the absolute density, yield of volatile substances, ash content, and total porosity were analyzed. The microstructure of the resulting coke was analyzed by X-ray diffraction, for which the evaluation criteria were the interplanar spaces d 002 and d 100 and the sizes of the Lc and La crystallites. The scanning electron microscopy (SEM) technique was used to confirm the results of the analysis of the formed structure of shale coke obtained earlier. The calcined samples were classified as cokes with an isotropic structure. In addition, the fractional composition of the obtained gasoline and gas oil fractions of delayed coking of shale resin was analyzed.
