Abstract

Abstract: The investigation of the oil shale pyrolysis with a solid heat carrier was carried out using the experimental retorting system that simulates the Galoter industrial process. This system allows verifying both fractional composition of the oil shale and solid heat carrier, and their ratio and temperature. The oil shale of the Leningradsky deposit was used in the work, and quartz sand was used as the solid heat carrier. It is shown that the yield of the shale oil under the pyrolysis with solid heat carrier exceeds by more than 20% the results received in the standard Fisher retort. Using ash as the solid heat carrier results in a decrease in the yield of oil and gas with simultaneous increase in the amount of the solid residue. This is due to the chemical interaction of the acid components of the vapor-gas mixture with the oxides of alkaline-earth metals that are part of the ash.
