Abstract
The oxidation behaviour of Göynük oil shale and its demineralization products up to 500°C, in an air atmosphere was investigated. The kerogen of a Turkish shale was isolated by successive HCl and HF demineralization procedures. The products obtained after each demineralization step were oxidized in an air atmosphere at different reaction temperatures. The weight-loss data was recorded and the effect of carbonates and silicates on the total yield of oxidation products was determined. The spent shale after the oxidation experiments were analysed by infrared spectroscopy. The results indicated that the oxidation reactions are catalysed by carbonates and inhibited by silicates.
