This research focused on the characterization and kinetics of Siberian and Tatarstan crude oils by gas chromatography, combustion calorimetry, and thermogravimetry (TG-DTG) techniques. Calorimetric experiments show that crude oil with higher saturate content and low resin fraction has higher heating value. TG-DTG curves indicates that the crude oils undergoes two major transitions when subjected to an oxidizing and constant rate environment known as low- and high-temperature oxidations at each heating rate studied. Kinetic analysis in the low- and high-temperature oxidation regions was performed using model-free methods knows as Ozawa-Flynn-Wall and Kissinger-Akahira-Sunose. Throughout the study, it was observed that the activation energy values of the crude oil samples are varied between 41-72 and 145-198 kJ mol(-1) in low- and high-temperature oxidation regions, respectively.

Chemical evaluation and kinetics of Siberian, north regions of Russia and Republic of Tatarstan crude oils
Varfolomeev, Mikhail A.; Nagrimanov, Ruslan N.; Samatov, Aizat A.; Rakipov, Ilnaz T.; Nikanshin, Alexander D.; Vakhin, Alexey V.; Nurgaliev, Danis K.; Kök, Mustafa Verşan (2016-01-01)
In this research, thermal characteristics and model free kinetics of five different degrees American Petroleum Institute gravity crude oil samples from different locations were studied using combustion calorimetry and thermogravimetry (TGA) techniques. Higher heating values of crude oils were determined from the combustion calorimetry experiments. It was shown that these values increase with an increase in saturate fraction and degrees API gravity of studied samples and decrease with an increase in viscosit...
Characterization and Kinetics of Siberian and Tatarstan Regions Crude Oils Using Differential Scanning Calorimetry
Varfolomeev, M. A.; Rakipov, I. T.; Isakov, D. R.; Nurgaliev, D. K.; Kök, Mustafa Verşan (2015-01-01)
In this study, nonisothermal kinetics and thermal analysis of Siberian and Tatarstan regions crude oils is studied by differential scanning calorimetry (DSC) at different heating rates. DSC curves revealed two reaction regions in the temperature range of 20-600 degrees C, known as low and high temperature oxidation, respectively. Three different kinetic methods (ASTM, Borchardt and Daniels, and Roger and Morris) were used to determine the kinetic parameters of the samples and it was observed that the activa...
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...
Effect of clay on crude oil combustion by thermal analysis techniques
Kök, Mustafa Verşan (Springer Science and Business Media LLC, 2006-05-01)
This research was aimed to investigate the role of clay on the combustion and kinetic behavior of crude oils in limestone matrix. For this purpose, simultaneous TG (thermogravimetry) and DTA (differential thermal analysis) experiments were performed at three different heating rates as 10-15 and 20 degrees C min(-1), respectively. A uniform trend of decreasing activation energies was observed with the addition of clay. It was concluded that clays surface area affects the values of Arrhenius constant, while i...
Light crude oil combustion in the presence of limestone matrix
Kök, Mustafa Verşan; Keskin, C; Madarasz, J; Bagci, S (Springer Science and Business Media LLC, 2004-01-01)
In this study the combustion characteristics of crude oils (Karakus and Beykan) in the presence of a limestone matrix were determined using the thermogravimetry (TG/DTG). Experiments were performed at a heating rate of 10degreesC min(-1), whereas the air flow rate was kept constant at 10 L h(-1) in the temperature range of 20-900degreesC. In combustion with air, three distinct reaction regions were identified in all crude oil/limestone mixtures studied known as low temperature oxidation (LTO), fuel depositi...
