Abstract
In the article low-temperature pyrolysis of coal of “Saryadyr” deposit with determination of physical and chemical properties of coal and products of its thermal destruction 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, as well as their main characteristics (component composition, calorific value, etc.) were determined. The convergence of the results (from 6 experiments) is quite satisfactory. The thermal balance of coal pyrolysis was carried out taking into account the average yields of products.
