Abstract
The composition and reactivity characteristics of Khoot coal from Mongolia in the processes of pyrolysis, gasification, thermal dissolution, and the production of porous materials were determined. It was established that the coal is characterized by high activity in the reactions of destruction. In the process of semicoking, the yield of liquid tar was as high as 10%. Highly porous activated carbons with specific surface areas to 900 m2/g and high sorption capacities were obtained by the steam activation of carbonizates. To 60.8% liquid products at low gas formation can be obtained from the Khoot coal in the process of thermal dissolution in a hydrogen-donor solvent at 450°C without the use of hydrogen.
