Characterization and Kinetics of Siberian and Tatarstan Regions Crude Oils Using Differential Scanning Calorimetry
Varfolomeev, M. A.; Rakipov, I. T.; Isakov, D. R.; Nurgaliev, D. K.; Kök, Mustafa Verşan (2015-01-01)
In this study, nonisothermal kinetics and thermal analysis of Siberian and Tatarstan regions crude oils is studied by differential scanning calorimetry (DSC) at different heating rates. DSC curves revealed two reaction regions in the temperature range of 20-600 degrees C, known as low and high temperature oxidation, respectively. Three different kinetic methods (ASTM, Borchardt and Daniels, and Roger and Morris) were used to determine the kinetic parameters of the samples and it was observed that the activa...

Koçak, Ebru; ASLAN KILAVUZ, SEDA; ÖZTÜRK, FATMA; İmamoğlu, İpek; Tuncel, Süleyman Gürdal (2021-01-01)
In order to find the spatial distribution characteristics of elemental (EC) and organic (OC) carbon in fine particles, daily PM2.5 aerosol samples were collected at two different stations, between July 2014 and September 2015 in Ankara, Turkey. Concentrations of OC ranged from 2.1 to 42 mu g m(-3) at urban station. These concentrations were higher than those obtained for suburban station whose values ranged from 1.3 to 15 mu g m(-3). Concentrations of EC ranged from 0.7 to 4.9 mu g m(-3) at the urban statio...
Characterization of medium and heavy crude oils using thermal analysis techniques
Kök, Mustafa Verşan (Elsevier BV, 2011-05-01)
This study focused on the characterization of heavy and medium grade crude oils in limestone matrix using differential scanning calorimeter (DSC) and thermogravimetry (TG-DTG). DSC and TG-DTG curves produced for two different crude oils + limestone mixtures indicate that the crude oil undergoes two major transitions when subjected to an oxidizing and constant rate environment known as low- and high-temperature oxidation. Kinetic analysis in the low- and high-temperature oxidation regions were performed usin...
Characterization of oil shales by high pressure DSC
Kök, Mustafa Verşan; Pokol, Gy. (1999-01-01)
Pressurised differential scanning calorimeter (PDSC) has been used to obtain information on the pyrolysis and combustion characteristics of oil shales. Two distinct exothermic peaks were identified in combustion experiments known as low temperature oxidation (LTO) and high temperature oxidation (HTO) reaction regions. The pyrolysis process of all studied oil shale samples showed one exothermic effect at each total pressure studied. Kinetic data were analysed by Roger & Morris and Arrhenius methods and the r...
