In this research effect of particle size on the combustion properties of Cayirhan coal sample was studied. Non-isothermal thermogravimetry and derivative thermogravimetry (TG/DTG) experiment were carried out for twelve different size fractions of the Cayirhan coal sample. Thermogravimetry experiments were performed from ambient to 900 degrees C in air atmosphere. Differential thermogravimetric data were analysed using an Arrhenius type reaction model assuming a first-order reaction. Kinetic parameters of the samples are determined and the results are discussed.

Effect of particle size on coal pyrolysis Kök, Mustafa Verşan; Karacan, Ozgen; Hicyilmaz, Cahit (1998-01-01) This research comprises the effect of particle size on coal pyrolysis by thermogravimetry (TG/DTG). 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 20-600 degrees C, under nitrogen atmosphere. Different fractions of Cayirhan coal coal showed differences in TG/DTG curves, peak temperatures and residue values. The Arrhenius model is applied to determine the kinetic parameters from TG/DTG curves.
Effect of particle size and heating rate on the combustion of Silopi asphaltite Altun, Naci Emre; Kök, Mustafa Verşan (2002-05-01) In this study, the effects of particle size and heating rate on the combustion properties of Silopi asphaltite were investigated. Nonisothermal thermogravimetry experiments were carried out at three different size fractions and five different heating rates. The TG/DTG experiments were carried out from ambient to 900 degreesC in air. The data obtained were analyzed for the determination of the combustion characteristics of the sample. Also an Arrhenius type kinetic model complemented with the weighed mean ac...
Effect of Heating Rate on Thermal Properties and Kinetics of Raw and Cleaned Coal Samples Energy Sources Kök, Mustafa Verşan; Hiçyılmaz, Cahit (2003-01-01)
Effect of particle size and heating rate on the pyrolysis of Silopi asphaltite Altun, Naci Emre; Kök, Mustafa Verşan (Elsevier BV, 2003-5) This study comprises the effect of particle size and heating rate on the pyrolysis of Silopi, Turkey asphaltite by non-isothermal thermogravimetry. The TG/DTG experiments were performed at five different heating rates with three different size fractions from ambient up to 900 degreesC in nitrogen atmosphere. The pyrolysis characteristics of the samples were analyzed using TG/DTG curves. Also, the pyrolysis kinetics of the samples were determined using the Arrhenius type kinetic model and ASTM methods.

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...
