Özet
Goynuk oil shale, polystyrene and several polystyrene-oil shale blends were degraded in a thermobalance apparatus at atmospheric pressure. Experiments were carried out dynamically by increasing the temperature from 298 to 1173 K with heating rates of 10 and 60 K min(-1) under an argon atmosphere. Derivative thermogravimetric data were analyzed by a reaction rate model assuming first order kinetics. Effects of blending ratio of oil shale and polystyrene and heating rate on the thermal degradation kinetics were investigated. Kinetic parameters were determined and the results were discussed.
