The purpose of this research was to perform dry and wet forward combustion experiments for Turkish heavy oil reservoirs (Raman, Adiyaman and Çamurlu and Bati Kozluca) under different experimental conditions. In the experiments, a vertical tube was packed with crushed limestone and saturated with crude oil and water. It was observed that peak temperatures were higher when stabilized combustion was achieved and decreased as the combustion front approached the outlet end of the tube. In wet combustion experiments, the rate of combustion reaction and therefore rate of heat generation were reduced with the resultant drop in peak temperatures. In dry and wet combustion experiments, excess carbon-dioxide productions were observed due to the decomposition of carbonate minerals. Atomic H/C ratio of the fuel consumed decreased as the average peak temperature increased. Fuel consumption rate was higher for dry combustion experiments as the °API gravity of the crude oils increased. A decrease is also observed in fuel consumption rate after the water-air ratio value is reached to optimum value. For high water-air ratio in wet combustion experiments, a general decrease was observed as the °API gravity of the crude oils increased.

Comparative Pyrolysis and Combustion Kinetics of Oil Shales Kök, Mustafa Verşan (2000-02-01) In this research, thermal characteristics and kinetic parameters of eight Turkish oil shale samples were determined by thermogravimetry (TG/DTG) at non-isothermal heating conditions both for pyrolysis and combustion processes. A general computer program was developed and the methods are compared with regard to their accuracy and the ease of interpretation of the kinetics of thermal decomposition. Activation energies of the samples were determined by five different methods and the results are discussed.
Investigation of alternative biomass fuels and Turkish lignites at high heating rate pyrolysis and combustion conditions Magalhaes, Duarte; Kazanç Özerinç, Feyza; Yozgatlıgil, Ahmet; Department of Mechanical Engineering (2021-2-12) The objective of this work was to investigate alternative Turkish fuels fortheir ignition, combustion, pyrolysis, and gasification behavior and to select alternative fuels for co-firing, co-pyrolysis, and co-gasification applications based on low and high heating rate experimental results. Agricultural biomass (olive residue, almond shell, and hazelnut shell)and Turkish lignites (Tunçbilek, and Soma) were chosen as the feedstocks. Severalexperimental rigs used such as thermogravi...
Investigation of combustion of lignite and torrefied biomass in a thermogravimetric analyzer (TGA) and in a circulating fluidized bed (CFB) under oxy-fuel combustion conditions Barzegar, Ramin; Yozgatlıgil, Ahmet; Department of Mechanical Engineering (2019) In this study, the combustion of Turkish lignites (Orhaneli and Soma), torrefied woodchip, and their blends was studied under oxygen-enriched and oxy-fuel combustion conditions in a thermogravimetric analyzer. The iso-conversional kinetic methods were used to estimate the Arrhenius parameters and the uncertainty assessments associated with the kinetic calculations were considered. The co-combustion experiments showed a synergetic effect between the biomass samples and Orhaneli lignite. Based on the obtained...
Chemical evaluation and kinetics of Siberian, north regions of Russia and Republic of Tatarstan crude oils Varfolomeev, Mikhail A.; Nagrimanov, Ruslan N.; Samatov, Aizat A.; Rakipov, Ilnaz T.; Nikanshin, Alexander D.; Vakhin, Alexey V.; Nurgaliev, Danis K.; Kök, Mustafa Verşan (2016-01-01) In this research, thermal characteristics and model free kinetics of five different degrees American Petroleum Institute gravity crude oil samples from different locations were studied using combustion calorimetry and thermogravimetry (TGA) techniques. Higher heating values of crude oils were determined from the combustion calorimetry experiments. It was shown that these values increase with an increase in saturate fraction and degrees API gravity of studied samples and decrease with an increase in viscosit...
Modelling of in situ combustion for Turkish heavy crude oil fields Kök, Mustafa Verşan (1995-01-01) Different models were used to determine the possibility of in situ combustion applications for heavy crude oil fields in south-east Turkey. In the first approach a one-dimensional model was developed, in which the frontal advance concept is combined with mass and energy balance equations with certain boundary conditions, limitations and assumptions. The recovery histories of three oil fields were determined; the highest recovery was obtained in field 2 with dry combustion and in field 1 with wet combustion,...
