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.

Effect of metal oxide on light oil combustion - TA and kinetic analysis Kök, Mustafa Verşan (Springer Science and Business Media LLC, 2003-01-01) Simultaneous thermogravimetry (TG) and differential thermal analysis (DTA) were applied to light crude oil combustion in the presence and absence of metal oxide. In crude oil-limestone mixture, three main transitional stages are detected. These are distillation, low-temperature oxidation (LTO) and high temperature oxidation (HTO) regions respectively. In the case of experiments with Fe(III)chloride at different amounts, the shape of TG-DTA curve is changed considerably. Kinetic parameters of the samples are...
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...
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...
Crude oil characterization using TGA-DTA, TGA-FTIR and TGA-MS techniques Kök, Mustafa Verşan; Nurgaliev, Danis K. (2017-06-01) In this research, combustion characterization and kinetics of four different origin crude oil samples were determined using thermogravimetry - differential thermal analysis (TGA-DTA) and thermogravimetry - Fourier transform infrared (TGA-FTIR) and thermogravimetry mass spectrophotometry (TGA-MS) techniques.
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...
