In this study, four oil-shale samples (Nigde-Ulukisla) excavated from Central Anatolia Turkey were analyzed where this region is believed to have a high potential of oil in its shale rich outcrops. The samples (similar to 40 g) were combusted at 50 psi gas injection pressure, at an air injection rate of 1.5 L min(-1) in a combustion-reaction cell. All the experiments were conducted up to 600 degrees C. The percentages of oxygen consumption and carbon monoxide and carbon dioxide production were obtained instantaneously with respect to time. The combustion periods and relative reaction rates were determined by examining the effluent gas concentration peaks. Activation energies of the samples were determined using Weijdema's approach. It was observed that the activation energies of the samples are varied between 22-103 kJ mol(-1).

Thermal characteristics and kinetics of crude oils and SARA fractions Kök, Mustafa Verşan (Elsevier BV, 2013-10-10) In this study, two Turkish crude oils from southeastern part of Turkey and their saturate, aromatic and resin fractions were analyzed by thermogravimetric analysis (TGA). The experiments were performed at three different heating rates (5, 10, 15 degrees C/min) under air atmosphere. Two different reaction regions were observed from thermogravimetry (TG), differential thermogravimetry (DTG) curves due to the oxidative degradation of crude oil components. From TGA curves, it was detected that the heavier fract...
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...
Non-isothermal kinetic analysis and feasibilty study of medium grade crude oil field Kök, Mustafa Verşan (Springer Science and Business Media LLC, 2008-03-01) In this research, non-isothermal kinetics and feasibility study of medium grade crude oil is studied in the presence of a limestone matrix. Experiments were performed at a heating rate of 10 degrees C min(-1), whereas the air flow rate was kept constant at 50 mL min(-1) in the temperature range of 20 to 600 degrees C (DSC) and 20 to 900 degrees C (TG). In combustion with air, three distinct reaction regions were identified in all crude oil/limestone mixtures, known as low temperature oxidation (LTO), fuel d...
Geological Considerations for the Economic Evaluation of Turkish Oil Shale Deposits and Their Combustion-Pyrolysis Behavior Kök, Mustafa Verşan (Informa UK Limited, 2010-01-01) The oil shale deposits in Turkey are widely distributed in middle and western Anatolia. Turkish oil shales are of Palaeocene-Eocene and middle upper Miocene age. Current reserves of oil shales are approximately 2,220 million tons (total reserve) and mainly are located in Himmetoglu, Seyitomer, Beypazari, and Hatildag deposits. Some petrological, geochemical, Fisher Assay, and fluidized combustion tests are performed for these oil shale fields, and it was concluded that Himmetoglu oil shale is the most appro...
Geological considerations for the economic evaluation of oil shale deposits in Turkey Şener, Mehmet; Şengüler, Ilker; Kök, Mustafa Verşan (Elsevier BV, 1995-7) Geological information is given on four oil shale fields in middle and western Anatolia: Himmetoǧlu, Seyitömer, Beypazari{dotless} and Hati{dotless}ldaǧ. Some petrological, geochemical, Fischer assay and fluidized bed combustion test results for the oil shales are also presented. As a result of economic evaluation, it was concluded that Himmetoǧlu oil shale is the most appropriate for domestic and industrial utilization.
