Abstract:
In the article the low-temperature pyrolysis of Kazakhstan lowgrade 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.
