A Study on Thermal Decomposition Kinetics of Some Turkish Coals

Abstract

The kinetic model that describes the weight loss of Turkish coals under pyrolysis conditions has been investigated. Nonisothermal thermogravimetric analysis data on 12 Turkish coals have been compared with the predictions of single first-order and distributed activation energy models. It was observed that the distributed activation energy model appears to provide a quantitatively satisfactory description of the devolatilization behavior of Turkish coals.
