abstract = "The main objective of this study was to investigate the carbonization of Tun{\c c}bilek lignite by TG. Thermogravimetric analyses were performed at different conditions such as heating rates of 10 and 30 °C/min, temperatures of 500, 650 and 800 °C, particle sizes of 1700-700 and 150-100 um, heating mediums of nitrogen and carbon dioxide and gas flow rates of 15 and 40 cm 3/min. Based on TG curves, the kinetic parameters of the process were calculated using the methods of Coats-Redfern, Horowitz-Metzger and Dharwadkar-Karkhanavala in order to illuminate the mechanism of carbonization of Tun{\c c}bilek lignite. The carbonization kinetic models of Tun{\c c}bilek lignite were set up. The main carbonization stage could be described by the second order global models for Tun{\c c}bilek lignite and activation energies varied in the range of 31.7-69.0 kJ/mol.",
