Abstract
In the article pyrolysis of Kazakhstan oil shale with determination of physical and chemical properties of oil shale and products of its thermal decomposition is carried out. Elemental analysis of oil shale and analysis of mineral part of oil shale were carried out. Four parallel experiments of oil shale pyrolysis process were carried out, as a result of which the yields of such products as semi-coke, pyrolysis oil, combustible gas were determined, as well as their main characteristics (component composition, calorific value, etc.) were determined. The convergence of the results (from 4 experiments) is quite satisfactory.
