In this study, combustion and pyrolysis behavior of diesel and canola oil is investigated using thermal analysis techniques known as thermogravimetry (TG-DTG) and differential scanning calorimetry (DSC) at different heating rates. Reaction regions, peak temperatures, mass loss, heat flow rates, ignition temperatures, and specific heat of diesel and canola oil samples are determined using TG-DTG and DSC data. It was observed that as the heating rate of the reactions increased, peak temperatures of the reactions shift higher; implying that as the heating rate of the reactions increases the reactions lose their sensitivity. Five different kinetic methods were applied to determine combustion reaction parameters of the reactions. It was observed that averages of the activation energies of the samples are in the order of canola oil and diesel for different heating rates.

Combustion characteristics of crude oil-limestone mixtures: High pressure thermogravimetric analysis and their relevance to in-situ combustion Kök, Mustafa Verşan; Price, D. (1997-12-01) High pressure thermogravimetric analysis (HPTG) was used in order to study the oxidation of crude oil in a porous medium under pressurised conditions for simulation of in-situ combustion during oil recovery. Three distinct reaction regions were observed from the HPTG curves in an oxidising environment subjected to a constant heating rate. These were low temperature oxidation, fuel deposition and high temperature oxidation. The method of Coats and Redfern was used to obtain kinetic parameters and the results...
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...
Catalytic effects of metallic additives on the combustion properties of crude oils by thermal analysis techniques Kök, Mustafa Verşan (2001-08-20) Differential scanning calorimetry (DSC) was applied to crude oil combustion in the presence and absence of metal chlorides. It was observed that in the presence of smaller ratios of metallic additives, the surface reactions were predominant and the catalyst did not affect the reactions much. Three reaction regions were identified as low temperature oxidation (LTO), middle temperature oxidation (MTO) and high temperature oxidation (HTO). Kinetic parameters of the reaction regions were determined with two dif...
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...
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.
