Abstract: The gasification behavior of pine wood sawdust was investigated in CO 2 with different heating rates of 5, 10, 15, and 20 °C/min from room temperature to 1400 °C by thermogravimetric analysis (TGA) and mass spectrometry (MS). It was also examined under Ar to compare the differences observed under CO 2 at heating rate of 10 °C/min. Kinetics of pine wood sawdust thermal decomposition was determined by the models of FWO, KAS and master plot method. TGA results revealed different reaction sections from pyrolysis to char gasification under CO 2 . The pyrolysis behavior was similar under CO 2 and Ar and had a similar energy required value about 590 kJ/kg from 250 °C to 420 °C. CO, CH 4 , and H 2 were the primary gases obtained from thermal decomposition, and the amounts of which in CO 2 atmosphere were higher than those obtained in Ar. The average activation energy for pyrolysis under CO 2 was 184.72 kJ/mol.
