Özet
This study investigates the thermal degradation behavior of poultry litter-based biomass pellets, with and without the addition of 10 mass% clinoptilolite, using thermogravimetric analysis and differential thermogravimetric analysis. Six pellet samples were prepared with particle sizes of 3 mm, 5 mm, and 8 mm and analyzed in nitrogen (N2) and oxygen (O2) atmospheres. Thermal parameters, including the initial (T i), maximum (T m), and final (T f) decomposition temperatures, were evaluated alongside mass loss and compositional data. The T i ranged from 162.41 (PL-8) to 193.92 degrees C (PL90C10-3), T m ranged from 293.23 to 302.91 degrees C, and Tf varied from 515.76 to 606.35 degrees C. Total mass was lowest in PL90C10-3 (68.09%) and lowest in PL-8 (55.49%). The addition of clinoptilolite increased volatile matter (up to 45.32%) and fixed carbon content (up to 16.78%), reducing ash content compared to zeolite-free samples. These results indicate that particle-size reduction and the addition of natural clinoptilolite positively influence the thermal degradation characteristics and thermal stability of poultry litter pellets.
