Evaluation of turkish oil shales - Thermal analysis approach

In this research, thermal characteristics of three Turkish oil shales (Himm etoglu, Beypazari and Hatuldag) were studied by thermal analysis techniques (differential scanning calorimetry, thermogravimetry and pressurised diffe rential scanning calorimetry). Two distinct exothermic peaks were identifie d in all experiments known as low-temperature oxidation and high-temperatur e oxidation reaction regions. Kinetic data were analysed by Arrhenius, and Coats and Redfern models and the results are discussed.
