摘要：

The coal sample of the Shivee Ovoo deposits has been non-isothermally pyrolysed in a thermogravimetric analyser to determine the influence of temperature, heating rate and purge gas employed on the thermal degradation of the sample. The heating rates investigated in the TG were 10-50 K min(-1) to final temperature of 1000 degreesC. N-2 or CO2 were employed as well as type of purge gas on the process of thermal degradation of the coal sample. The coal was also investigated in a fixed bed reactor to determine the influence of temperature and heating rate of the pyrolysis on the yield of products and composition of the gases evolved. The main gases produced were H-2, CH4, C2H2, C2H4, C2H6, C3H6 and C3H8 and also minor concentrations of other gases.
