The technical characteristics, organic elemental composition of coal and inorganic elemental composition of coal ash of Ulaan-Ovoo deposit have been determined. The thermal stability of coal organic mass has been investigated by thermogravimetric analysis: the mechanisms of the thermal decomposition of the coal organic mass have been explained and the thermal stability indices (T5%, T15% and T25%) has been determined. The coal of Ulaan-Ovoo deposit processed by pyrolysis under vaarious heating temperatures and determined the yields of pyrolysis products such as hard residue, condensed liquid (tar and pyrolysis water) and uncondensed gas products. On the basis of proximate, ultimate, thermogravimetric and FTIR analysis results have been confirmed that the Ulaan-Ovoo coal is a middle rank subbituminous D mark. The liquid tar product of pyrolysis of Ulaan-Ovoo coal was investigated by FTIR and GC/MS analysis. Also the pyrolysis hard residue and activated carbon were characterized.
