Pyrolysis analysis and kinetics of crude oils

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 kinetic parameters of crude oils studied. It was observed that as crude oils gets heavier (degrees API decreases) cracking activation energy increases. Activation energy of cracking also show a general trend with asphaltene content.

Thermal investigation of Seyitomer oil shale
Kök, Mustafa Verşan (2001-03-22)
This research presents the results of experimental study on the thermal investigation of Seyitomer oil shale sample. Thermogravimetry (TG/DTG) and differential scanning calorimetry (DSC) were used to determine the thermal behaviour of the oil shale sample. From the experiments and kinetic analysis, it was observed that Seyitomer oil shale sample have more than one reaction region where the activation energies of the first region are higher. Higher heating rates resulted in higher reaction temperatures both ...
Pyrolysis and Combustion Studies of Fossil Fuels by Thermal Analysis Methods Review
Kök, Mustafa Verşan (1995-02-01)
Instances where differential scanning calorimetry, thermogravimetry and differential thermal analysis have been applied to study the pyrolysis and combustion behaviour of fossil fuels (peat, lignite, bituminous coals, anthracite, oil shales, crude oils, lignite-oil mixtures, etc.) are reviewed. The literature survey showed that thermal methods were important not only theoretically but also from a practical point of view.

Kök, Mustafa Verşan (2002-01-01)
In this study, instances where thermal analysis techniques ( differential scanning calorimetry, thermogravimetry, differential thermal analysis, etc.) have been applied for fossil fuel characterisation and kinetics are reviewed. The scientific results presented clearly showed that thermal analysis is a well-established technique used in fossil fuel research area. The literature survey showed that thermal methods were important not only theoretically but also from a practical point of view.
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 decomposition of Tatarstan Ashal'cha heavy crude oil and its SARA fractions
Varfolomeev, Mikhail A.; Galukhin, Andrey; Nurgaliev, Danis K.; Kök, Mustafa Verşan (2016-12-15)
In this research, heavy crude oil from Ashal'cha field, Republic of Tatarstan, and its SARA (saturate, aromatic, resin and asphaltene) fractions were analyzed by differential scanning calorimetry (DSC) and thermogravimetry (TGA) methods. The experiments were performed at three different heating rates (10, 20, 30 degrees C/min) for DSC and at single heating rate for TGA analysis, all under the air atmosphere. In DSC experiments, two main reaction regions were detected at each heating rate known as low and hi...
