Abstract

The pyrolysis process is fundamental in many deep coal utilization technologies. The comparison of conversion of three different types of coal was carried out utilizing thermal analysis in the atmosphere of argon, carbon dioxide, and steam within the temperature range from ambient temperature to 1000°C. The anthracite, bituminous coal, and lignite of Siberian deposits were studied. It was found that within the temperature range of 20-700°C for bituminous coal and lignite, and within 20-800°C for anthracite, the differences between mass loss rate in inert medium and other studied samples were insignificant. While flue gases (from fossil fuels burnt with low excess air ratio) in general consist of carbon dioxide and steam. Thus, they could be used for the pyrolysis of studied fuels within the mentioned temperature ranges.
