Recently, there has been a growing global interest in processing low-grade types of solid fuels, such as oil shale. In the near future, the role of solid fuels in the country's fuel and energy balance is expected to increase, primarily due to their large reserves. Based on this, this work evaluates the semi – coke obtained by semi-coking low-grade types of solid combustible fossils-oil shale of the Baltic basin (Leningrad deposit). The influence of process parameters (temperature and holding time) on the physical and chemical properties of shale semi-coke was studied experimentally. Based on the data obtained, it is concluded that the obtained samples of semi-coke from oil shale and brown coal can be used as a substitute for coke in various industries and the national economy.
