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 py- rolysis products such as hard residue, condensed liquid (tar and pyrolysis water) and uncon- densed gas products. On the basis of proximate, ultimate, thermogravimetric and FTIR anal- ysis 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.
