In this research, non-isothermal kinetics and feasibility study of medium grade crude oil is studied in the presence of a limestone matrix. Experiments were performed at a heating rate of 10 degrees C min(-1), whereas the air flow rate was kept constant at 50 mL min(-1) in the temperature range of 20 to 600 degrees C (DSC) and 20 to 900 degrees C (TG). In combustion with air, three distinct reaction regions were identified in all crude oil/limestone mixtures, known as low temperature oxidation (LTO), fuel deposition (FD) and high temperature oxidation (HTO). The activation energy values were in the order of 5-9 kJ mol(-1) in LTO region and 189-229 kJ mol(-1) in HTO region. It was concluded that the medium grade crude oil field was not feasible for a self-sustained combustion process.

Thermo-oxidative reactions of crude oils Kök, Mustafa Verşan (Springer Science and Business Media LLC, 2011-08-01) In this research, thermo-oxidative reactions of crude oils of different origin are determined in limestone matrix using simultaneous thermogravimetry and differential thermal analysis (TG-DTA) systems. Two different reaction regions were identified known as low temperature (LTO) and high temperature oxidation (HTO). Kinetic parameters of the samples were determined by four different methods and the results are discussed.
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...
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...
Influence of reservoir rock composition on the combustion kinetics of crude oil Kök, Mustafa Verşan (Springer Science and Business Media LLC, 2009-08-01) In this research, the effect of different lithology (limestone and sandstone) on the combustion of light crude oils was investigated using thermal analysis techniques. Three distinct reaction regions were identified in all of the crude oil+limestone and sandstone mixtures, known as low temperature oxidation (LTO), fuel deposition (FD) and high temperature oxidation (HTO), respectively. Kinetic analysis of the crude oil+limestone and sandstone mixtures was performed using Coats and Redfern method and the res...
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...
