Abstract
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.
