<p>Pyrolysis and combustion process of Mongolian Pine tree sawdust have been investigated by the isothermal thermogravimetric technique, at several different operating temperatures using the vertical fixed bed reactor. Gas chromatography analysis was employed to characterize the composition of evolving gas in samples during the pyrolysis process. Thermal degradation results showed that pine sawdust mainly devolatilized around 300-450°C temperatures with total volatile yield about 78%. When it is comparing with the Mongolian brown coals, devolatilization was higher at above 600°C (the volatile yield was 39-54% for all brown coals) than lower temperatures (7-32% at 600°C˂). The reaction kinetics activation energy (<i>Ea</i>), pre-exponential factor (<i>A</i>) were determined using first-order method for pyrolysis process. The apparent activation energy of Pine sawdust is 29.3 kJ/mol during pyrolysis process at range temperature of 600-900°C. The main evolving gaseous products during pyrolysis were H₂, CH₄, CO, CO₂, and their yields were relatively each pyrolysis temperatures.</p>
