In this research kinetic analysis of the Tuncbilek lignite and its mixture with different binders (molasses, CMC, sulphide
liquor, heavy crude oil, sodium silicate,cornstarch, lime, peridur, bentonite, cement and poly(vinyl-acetate)) were analysed
by thermogravimetric (TG/DTG) methods. Two different kinetic models (Arrhenius and Coats–Redfern) were used to determine the
activation energies of the samples studied. The concept of weighed mean activation energy was applied to determine the overall
reactivity of the samples. It was observed that molasses, CMC, heavy crude oil, peridur, bentonite and poly(acetate) decreased
the activation energy of the coal sample, whereas, all other binders increased the activation energy of the coal sample.

In this research, differential scanning calorimetry (DSC) was used to determine the combustion behavior and kinetic analysis
of raw and cleaned coal samples of different size fractions. DSC curves of the three coal samples (Soma, Tuncbilek and Afsin
Elbistan) showed two reaction regions. The first reaction region was due to moisture loss (endothermic) and observed in the
temperature range of ambient to 150°C. The second region was the exothermic region due to the combustion and observed in the
temperature range of 150 to 600°C. Kinetic parameters of the samples were determined using Roger and Morris kinetic model
and the results are discussed.

In this research, thermogravimetry (TG/DTG) was used to determine the kinetic analysis of different coals and effect of cleaning process on kinetic parameters of raw and cleaned coal samples from Soma, Tuncbilek and Afsin Elbistan regions.
