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 results are discussed.

Effect of clay on crude oil combustion by thermal analysis techniques Kök, Mustafa Verşan (Springer Science and Business Media LLC, 2006-05-01) This research was aimed to investigate the role of clay on the combustion and kinetic behavior of crude oils in limestone matrix. For this purpose, simultaneous TG (thermogravimetry) and DTA (differential thermal analysis) experiments were performed at three different heating rates as 10-15 and 20 degrees C min(-1), respectively. A uniform trend of decreasing activation energies was observed with the addition of clay. It was concluded that clays surface area affects the values of Arrhenius constant, while i...
Effect of different clay concentrations on crude oil combustion kinetics by thermogravimetry Kök, Mustafa Verşan (2010-03-01) The objective of this research was to investigate the effect of different clay composition and concentrations on the thermal behaviour and kinetics of heavy crude oil in limestone matrix by thermogravimetry (TG/DTG). In TG/DTG experiments, three distinct reaction regions were identified in all of the crude oil + limestone mixture known as low temperature oxidation (LTO), fuel deposition (FD) and high temperature oxidation (HTO) respectively. Addition of clay to porous matrix significantly affected the react...
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...
Light crude oil combustion in the presence of limestone matrix Kök, Mustafa Verşan; Keskin, C; Madarasz, J; Bagci, S (Springer Science and Business Media LLC, 2004-01-01) In this study the combustion characteristics of crude oils (Karakus and Beykan) in the presence of a limestone matrix were determined using the thermogravimetry (TG/DTG). Experiments were performed at a heating rate of 10degreesC min(-1), whereas the air flow rate was kept constant at 10 L h(-1) in the temperature range of 20-900degreesC. In combustion with air, three distinct reaction regions were identified in all crude oil/limestone mixtures studied known as low temperature oxidation (LTO), fuel depositi...
Oil shale kinetics by differential methods Kök, Mustafa Verşan (Springer Science and Business Media LLC, 2007-06-01) In this research, pyrolysis and combustion behavior of three different oil shale samples from Turkey were characterized using thermal analysis techniques (TG/DTG). In pyrolysis experiments, two different mechanisms causing mass loss were observed as distillation and cracking. In combustion experiments, two distinct exothermic peaks were identified known low and high temperature oxidation. On the other hand, determination of activation energies are required for the estimation of oil extraction conditions fro...
