Thermal characteristics and rheological behaviour of eight crude oils covered a wide range of fluid composition and properties were studied by differential scanning calorimeter (DSC) and viscometry. Wax appearance temperatures (WAT) of crude oils were determined by DSC and viscometry. Good agreement is obtained between the results. The dynamic viscosity in the Newtonian temperature range of the crude oils (above 30 degrees C) generally obeyed a simple first-order Arrhenius type of temperature dependence. Activation energies of flow in the non-Newtonian range are not uniquely defined.

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...
TGA and DSC investigation of different clay mineral effects on the combustion behavior and kinetics of crude oil from Kazan region, Russia Kök, Mustafa Verşan; Nurgaliev, Danis K. (2021-05-01) In this research, the effect of different clay minerals (bentonite, illite and kaolinite) on the combustion behavior and kinetics of crude oils from Kazan region (Russia) was studied using thermogravimetry (TGA) and differential scanning calorimeter (DSC). The ramped temperature experiments were performed at constant heating rates (10, 20 and 30 degrees C/min) under air atmosphere. In both TGA and DSC experiments, two reaction zones were identified known as low temperature oxidation (LTO) and high temperatu...
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...
Thermal characterization of different origin class-G cements Kök, Mustafa Verşan (2014-02-01) In this study, thermal characteristics and kinetics of three different origin class-G cements (Mix, Bolu, and Nuh) were studied using thermogravimetry (TG/DTG) and differential scanning calorimeter (DSC). In DSC curves at different heating rates a number of peaks were observed consistently in different temperature intervals. TG/DTG is used to identify the detected phases and the corresponding mass loss. In the dehydration kinetic study of the different origin class-G cement samples, three different methods ...
Thermal characteristics of crude oils treated with rheology modifiers Kök, Mustafa Verşan; Cloudy, P.; Martin, D.; Garcin, M.; Volle, J.L. (1997-12-01) Thermal characteristics of eight crude oils and their treatment with additives were studied by differential scanning calorimetry (DSC), thermomicroscopy, viscometer and pour point tester. Different additives were found as more effective for different type of crude oils depending on the wax content. Crude oils showed a reduced pour point after treatment with additives. Effects of different additives were also discussed by analysing the DSC curves and thermomicroscopy result.
