This research is focused on the effects of pressure (100-300 Pa) and matrix and on light crude oil combustion in sandstone matrix using pressurized differential scanning calorimetry (PDSC). Light crude oils and sandstone mixtures were prepared to give a composition of 15 mass% crude oil in sandstone matrix. A total of forty-eight PDSC experiments were performed. Roger and Morris kinetic model was used to analyse the data obtained from PDSC experiments 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 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...
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...
Influence of reservoir rock composition on the combustion kinetics of crude oil Kök, Mustafa Verşan (Springer Science and Business Media LLC, 2009-08-01) 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 res...
Heating rate effect on the DSC kinetics of oil shales Kök, Mustafa Verşan (2007-12-01) This research was aimed to investigate the combustion and kinetics of oil shale samples (Mengen and Himmetoglu) by differential scanning calorimetry (DSC). Experiments were performed in air atmosphere up to 600 degrees C at five different heating rates. The DSC curves clearly demonstrate distinct reaction regions in the oil shale samples studied. Reaction intervals, peak and burn-out temperatures of the oil shale samples are also determined. Arrhenius kinetic method was used to analyze the DSC data and it w...
