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 in DSC and TG/DTG experiments.

Thermal and geochemical investigation of Seyitomer oil shale
Kök, Mustafa Verşan; Hufnagel, Heinz; Sonel, Nurettin (Elsevier BV, 2001-4)
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.
Pyrolysis analysis and kinetics of crude oils
Kök, Mustafa Verşan (1998-01-01)
This research presents the results of an experimental study on the determination of pyrolysis behaviour and kinetics of six crude oils by differential scanning calorimetry (DSC) and thermogravimetry (TG/DTG). Crude oil pyrolysis indicated two main temperature ranges where loss of mass was observed. The first region between ambient to 400 degrees C was distillation. The second region between 400 and 600 degrees C was visbreaking and thermal cracking. Arrhenius-type kinetic model is used to determine the kine...
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...
Geological and thermal characterization of EskiAYehir region oil shales
Kök, Mustafa Verşan (2014-04-01)
In this study, geological consideration and thermal characterization of oil shale samples were studied. Geological considerations of oil shale samples were studied using Rock-Eval analysis and it was observed that the kerogen type of all oil shale samples were in the majority of Type-I and II. Thermal characteristics and kinetics analysis of oil shale samples were studied by non isothermal differential scanning calorimeter (DSC) and thermogravimetry (TG/DTG). In air atmosphere, two different mechanisms caus...
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...
