Özet

In the study, the catalytic pyrolysis behavior of low-rank Umutbaca coal with the addition of CaO was examined using thermal analysis methods. For this purpose, the effect of adding CaO to coal on both the pyrolysis temperatures of the coal and the composition of the gas and solid product (char) was investigated. Also, the kinetic analysis was carried out to characterize the catalytic pyrolysis process by adding CaO to coal. Using the data obtained in TGA at heating rates of 2.5, 5, and 10 oC/min, the activation energies required for the pyrolysis process of coal both with and without CaO were calculated by KAS and FWO methods. Thermodynamic parameters including ∆H, ∆G, and ∆S were calculated with activation energies obtained from the FWO method. The thermodynamic suitability of adding CaO to a low rank coal such as Umutbaca for the pyrolysis process was investigated.
