This research was focused on the combustion kinetics and oxidation mechanisms of light crude oils in limestone and sandstone matrices. Similarity of the TGA-DTA curves was produced for different crude oils + limestone or sandstone mixtures indicates that the crude oil undergoes three major transitions, known as low-temperature oxidation, fuel deposition, and high-temperature oxidation when subjected to an oxidizing and constant rate environment. Kinetic analysis of the low- and high-temperature oxidation regions was performed using the ASTM and Arrhenius kinetic methods. In reaction mechanism of the combustion reactions, oxidation mechanisms, and rate-controlling steps of fluid-solid reactions in limestone matrix was also determined. It was observed that the linear behavior at elevated temperatures justifies the assumption that chemical reaction was the controlling step.

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 characterization of crude oils in the presence of limestone matrix by TGA-DTG-FTIR
Kök, Mustafa Verşan; Nurgaliev, Danis K. (2017-06-01)
In present work oxidation of two heavy oils in limestone matrix was studied using simultaneous thermo-gravimetry (TGA), derivative thermogravimetry (DTG) and FTIR-spectroscopy techniques in the temperature range from 25 to 900 degrees C. Before the measurements, the composition and properties of crude oils and limestone were evaluated. Obtained TG and DTG curves shows four different reaction regions: low temperature oxidation (LTO), fuel deposition (FD), high temperature oxidation (HTO) and decomposition of...
Thermal characterization, combustion and kinetics of different origin crude oils
Gundogar, Asli S.; Kök, Mustafa Verşan (2014-05-01)
In this research, the combustion behavior of six Turkish crude oils (light and medium type) was investigated by thermogravimetry/derivative thermogravimetry (TG/DTG) and differential scanning calorimetry (DSC) methods under atmospheric air in the absence of rock matrix. Two main reaction intervals were observed on all thermograms known as low temperature oxidation (LTO) and high temperature oxidation (HTO) regions. The resulting curves showed that the mass loss under combustion is accompanied by exothermic ...
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...
Calorimetric study approach for crude oil combustion in the presence of clay as catalyst
Varfolomeev, Mikhail A.; Nurgaliev, Danis K.; Kök, Mustafa Verşan (2016-01-01)
In this research, the effect of heating rate and different clay concentrations on light and heavy crude oils in limestone matrix was investigated by differential scanning calorimeter (DSC). In DSC experiments, two main distinct reaction regions were identified in all of the crude oil + limestone matrix + catalyst, known as low- and high-temperature oxidation respectively. It was observed that addition of clay to porous matrix significantly affected the thermal characteristics and kinetics of different origi...
