The Characterization of a Tar Sand Sample Using Differential Scanning Calorimeters

Senguler, I.
Kök, Mustafa Verşan
In this study, non-isothermal kinetics and a thermal analysis tar sand sample is studied by differential scanning calorimeter and pressurized differential scanning calorimeter. Differential scanning calorimeter and pressurized differential scanning calorimeter curves revealed two reaction regions in the temperature range of 20-600 degrees C. Effect of pressure was also studied in order to see the thermal behavior of a tar sand sample under different elevated pressures. Two different kinetic methods (ASTM and Borchald and Daniels) were used to determine the kinetic parameters of the samples.


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...
The Thermal Characterization of Crude Oils in a Limestone Matrix of Different Particle Size
Kök, Mustafa Verşan (2014-05-03)
In the first part of this research, the effect of particle size (35-100 mesh) on the calcination kinetics of a limestone sample was investigated by thermogravimetric analysis technique. Thermal studies showed that two main weight loss regions are observed in limestone samples of different particle size. In the second part of the research, thermal analysis of a medium crude oil sample in a limestone matrix of different particle size is analyzed. Two different reaction regions were observed known as low tempe...
The effect of lime addition on the combustion properties and sulfur contents of three different coals
Ozbas, Kazim Esber; Hiçyilmaz, Cahit; Kök, Mustafa Verşan (2002-01-01)
In this research, combustion characterization of 3 different coals of Turkey, from the Soma, Tuncbilek, and Afsin Elbistan regions, were investigated with thermal analysis techniques such as differential scanning calorimetry (DSC) and thermogravimetry (TG/DTG). Lime was added to these coals in concentrations of 3, 7, and 10% by weight to investigate the change in combustible sulfur content and sulfur in ash. It was observed that lime has a positive effect on sulfur emission. Kinetic analysis was also perfor...
The Chemistry, Kinetics, and Potential Utilization of Different Origins of Bentonite Samples
Kök, Mustafa Verşan (2014-01-17)
In this research, different origins of bentonite samples (non-treated, treated, and test) were studied by x-ray diffraction, Fourier transform spectrophotometer, viscometer, and thermogravimetry. It was observed that the major clay minerals were smectite and montmorillonite. Different band intervals were studied by Fourier transform. The weight loss regions related to the dehydration and de-hydroxylation process were determined by thermogravimetry. Kinetic parameters of the bentonite samples were determined...
Thermal characterization of different origin class-G cements
Kök, Mustafa Verşan (2014-02-01)
In this study, thermal characteristics and kinetics of three different origin class-G cements (Mix, Bolu, and Nuh) were studied using thermogravimetry (TG/DTG) and differential scanning calorimeter (DSC). In DSC curves at different heating rates a number of peaks were observed consistently in different temperature intervals. TG/DTG is used to identify the detected phases and the corresponding mass loss. In the dehydration kinetic study of the different origin class-G cement samples, three different methods ...
