Beypazari lignite was investigated by differential scanning calorimetry (DSC), thermogravimetry (TG), high pressure thermogravimetry (HPTG) and combustion cell experiments. All the experiments were conducted at non-isothermal heating conditions with a heating rate of 10 degrees C min(-1), in the temperature range of 20-700 degrees C. DSC-TG data were analysed using an Arrhenius-type reaction model assuming a first-order reaction. For the HPTG data the Coats and Redfern equation was used for kinetic analysis. In the combustion cell experiments the Fassihi and Brigham approach was used in order to calculate kinetic data. Finally a comparison is made between the kinetic results.

Non-isothermal DSC and TG/DTG analysis of the combustion of silopi asphaltites Kök, Mustafa Verşan (2007-06-01) In this research, non-isothermal combustion and kinetics of Silopi (Turkey) asphaltite samples were investigated by differential scanning calorimetry (DSC) and thermogravimetry (TG/DTG). A sample size of 10 mg, heating rates of 5, 10, 15 and 200C min(-1) were used in the temperature range of 20-600 degrees C, under air atmosphere. Two reaction regions were observed in DSC curves. The first region is due to the evaporation of moisture in asphaltite sample whereas, release of volatile matter and burning of ca...
An investigation into the thermal behavior of coals Kök, Mustafa Verşan (2002-10-01) The thermal behavior of 4 coal samples was investigated using simultaneous thermogravimetry (TG/DTG) and differential thermal analysis (DTA) methods. Upon heating the coals in an inert atmosphere up to 800degreesC, 31.44-43.82% weight loss occurs. The 2 temperature regions of increased chemical reactivity are evident in the coal samples studied Two different models determined kinetic analysis of the samples, and the results are discussed.
Kinetic analysis of DSC and thermogravimetry data for combustion of lignite Kök, Mustafa Verşan (1996-06-01) Thermal analysis increasingly being used to obtain kinetic data relating to sample decomposition. This work involves a comparative study of several methods used to analyse DSC and TG/DTG data obtained on the oxidation of Beypazari lignite. 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. For this study, the ratio method was regarded as the preferred method, because it permits the estim...
Recent developments in the application of thermal analysis techniques in fossil fuels Kök, Mustafa Verşan (2008-03-01) In this review, application of thermal analysis techniques (differential scanning calorimetry, thermogravimetry, differential thermal analysis, etc.) for fossil fuel characterization and kinetics are reviewed between 2001 and 2006. The results presented clearly showed that thermal analysis applications are well-established techniques used in fossil fuel research area.
Pyrolysis analysis and kinetics of crude oils Kök, Mustafa Verşan (1998-01-01) This research presents the results of an experimental study on the determination of pyrolysis behaviour and kinetics of six crude oils by differential scanning calorimetry (DSC) and thermogravimetry (TG/DTG). Crude oil pyrolysis indicated two main temperature ranges where loss of mass was observed. The first region between ambient to 400 degrees C was distillation. The second region between 400 and 600 degrees C was visbreaking and thermal cracking. Arrhenius-type kinetic model is used to determine the kine...
