The processes of the interaction of carbon material (thermoanthracite pouring) with a gas-air mixture in a heat chamber were studied while heating to 800–850°C. The influence of temperature, oxygen and carbon dioxide concentration on the formation efficiency of carbon monoxide, carbon dioxide, hydrogen and methane was determined. A pilot plant was created, which provided heating of the carbon material at the indicated temperatures and regulating the supply of air and carbon dioxide. It was found that a noticeable oxidation of the carbon material in the heat chamber in the presence of oxygen or carbon dioxide occurs at the temperatures above 500°C. Significant concentrations of carbon monoxide were formed at temperatures of 600–800°C. It was shown that when using gas mixtures with an oxygen content of 7–21% minimum concentrations of carbon monoxide are formed at an oxygen content of 14%. At temperatures above 500°C, the formation of hydrogen and methane in gas flows was noted. The methane yield increased with the decreasing oxygen content.
