Thermal behavior of Harbul asphaltites (SE Anatolia, Turkey) has been studied using thermogravimetric analysis at atmospheric pressure and with nitrogen as the ambient gas.Asphaltite samples were ground separated according to their size by sieving.Particle distribution chemical composition asphaltite fractions are given.TG/DTG data demonstrated two stages mass loss.The first stage, called primary volatization, occurs in range 200-600 °C, second secondary gasification, 600-800 °C.Kinetic parameters pyrolysis (activation energy, Arrhenius constant reaction rate constant) determined separately for both Coats-Redfern kinetic model.
