Abstract
In the article the low-temperature pyrolysis of Kazakhstan low-grade coal with determination of physical and chemical properties of coal and products of its thermal decomposition is carried out. Elemental analysis of coal and analysis of mineral part of coal were carried out. 6 parallel experiments of the process of low-temperature pyrolysis of coal were carried out, as a result of which the yields of such products as semi-coke, tar, combustible gas were determined, and also their main characteristics (component composition, calorific value, etc.) were determined. The convergence of the results (from 6 experiments) is quite satisfactory. The heat balance of coal pyrolysis was carried out taking into account the average yields of products.
