In this study, the effect of the mineral matter of Göynük oil shale on the conversion of organic carbon inkerogen into volatile hydrocarbons, polycyclic aromatic hydrocarbons (asphaltenes, preasphaltenes), and carbonin the solid residue was investigated. Kerogen was isolated by successive HCl, HNO3, and HF treatments. Aseries of temperature-programmed pyrolysis operations was performed with raw Göynük oil shale and eachproduct of every demineralization process. The results show that removal of the material soluble in HCl andHNO3 slightly affected the conversion of organic materials in the pyrolysis reactions. In contrast, removal ofthe material soluble in HF increased the conversion in pyrolysis reactions. This behavior is explained by theinhibitive effect of the silicate minerals. The leaching of mineral matter with HCl, HNO3, and HF caused noremarkable change in the composition of volatile hydrocarbons.
