dc.description.abstractIn this study, the effect of the mineral matter of Eynez lignite on the volatile hydrocarbon recovery, the yield of polycyclic aromatic hydrocarbons (asphaltenes, preasphaltenes), and the carbon in the solid residue was investigated. First, lignite was demineralized with HCl, HNO(3), and HF, successively. Then, the samples obtained from the demineralization step were pyrolyzed in isothermal pyrolysis reactor. The reaction temperatures are 450, 500, 550, 600, and 650 degrees C. Pyrolysis products were analyzed in capillary gas chromatography, and product evolution rate was calculated. The results show that removal of the inorganic elements in HCl decreased the volatile hydrocarbon recovery and that HNO(3) slightly affected the conversion of organic materials in the pyrolysis reactions. In contrast, removal of the inorganic elements in HF increased the conversion in pyrolysis reactions. This behavior is explained by the inhibitive effect of the silicate minerals.en_US
