Assessment of the Effect of Oxygen and Carbon Dioxide Concentrations on Gas Evolution During Heat Treatment of Thermoanthracite Carbon Material

Autor: Nikolai Gomelia, Olena Ivanenko, Yevgen Panov, Andrii Vahin, Serhii Leleka

Publikováno v: Journal of Ecological Engineering, Vol 21, Iss 2, Pp 139-149 (2020)

The processes of the interaction of carbon material (thermoanthracite pouring) with a gas-air mixture in a heat chamber are studied while heating to 800-850 °C. The influence of temperature, oxygen and carbon dioxide concentration on the formation e
