The results of an experimental study on the thermal and organic geochemical investigation of Seyitomer oil shale sample are presented. Thermogravimetry (TG/DTG) and differential scanning calorimetry (DSC) have been used to determine the thermal behaviour of the oil shale sample. On the other hand, organic carbon content, rock-eval pyrolysis, and gas and liquid chromatography experiments were conducted to determine geochemical properties of the oil shale sample.

Thermal investigation of Seyitomer oil shale Kök, Mustafa Verşan (2001-03-22) This research presents the results of experimental study on the thermal investigation of Seyitomer oil shale sample. Thermogravimetry (TG/DTG) and differential scanning calorimetry (DSC) were used to determine the thermal behaviour of the oil shale sample. From the experiments and kinetic analysis, it was observed that Seyitomer oil shale sample have more than one reaction region where the activation energies of the first region are higher. Higher heating rates resulted in higher reaction temperatures both ...
Oil shale kinetics by differential methods Kök, Mustafa Verşan (Springer Science and Business Media LLC, 2007-06-01) In this research, pyrolysis and combustion behavior of three different oil shale samples from Turkey were characterized using thermal analysis techniques (TG/DTG). In pyrolysis experiments, two different mechanisms causing mass loss were observed as distillation and cracking. In combustion experiments, two distinct exothermic peaks were identified known low and high temperature oxidation. On the other hand, determination of activation energies are required for the estimation of oil extraction conditions fro...
Thermal behavior and kinetics of crude oils at low heating rates by differential scanning calorimeter Kök, Mustafa Verşan (2012-04-01) The objective of this research was to investigate thermal behavior and kinetics of different origin crude oils in limestone matrix by differential scanning calorimeter (DSC) at low heating rates. In DSC experiments, three distinct reaction regions were identified in all of the crude oil + limestone mixtures known as low temperature oxidation (LTO), fuel deposition (FD) and high temperature oxidation (HTO) respectively. Kinetic analysis of the crude oil samples was determined by different models known as AST...
THERMAL ANALYSIS OF CO-FIRING OF OIL SHALE AND BIOMASS FUELS Ozgur, Emre; Miller, Sharon Falcone; Miller, Bruce G.; Kök, Mustafa Verşan (2012-01-01) The effect of co-firing of biomass fuels with oil shale on combustion was investigated Thermogravimetric analysis and differential scanning calorimetry were the tools used to perform the investigation. Since the combustion of biomass is highly exothermic, biomass fuels can serve as an appropriate fuel feedstock. Biomass fuels producing much volatile matter and containing less cellulose are good candidates for co-firing with oil shale. The biomass samples used in the study were hazelnut shell, wheat bran, po...
Comparative Pyrolysis and Combustion Kinetics of Oil Shales Kök, Mustafa Verşan (2000-02-01) In this research, thermal characteristics and kinetic parameters of eight Turkish oil shale samples were determined by thermogravimetry (TG/DTG) at non-isothermal heating conditions both for pyrolysis and combustion processes. A general computer program was developed and the methods are compared with regard to their accuracy and the ease of interpretation of the kinetics of thermal decomposition. Activation energies of the samples were determined by five different methods and the results are discussed.
