| Abstract |
Pyrolytic kinetic and thermodynamic analyses of date seeds were performed using thermogravimetric analysis (TGA) at different heating rates (10, 20, 30, and 40 degrees C/min) ranging from 20 degrees C to 900 degrees C. The curves of TGA and differential thermogravimetric analysis (DTG) showed that pyrolysis of date seeds consists of three areas of mass loss: dehydration, devolatilistion and char formation. The temperature range of each of these regions varies with heating rate. The Coats-Redfern method was used to perform the kinetic and thermodynamic evaluations for the devolatilisation region at different heating rates. The Zhuravlev diffusion equation proved to be the best-fit model with the highest regression coefficient values in the devolatilistion region. The average activation energy value for the devolatilistion region was estimated to be 186 kJ/mol. The kinetic data were used to determine the thermodynamic parameters (Delta H, Delta G, and Delta S). The data presented here are useful for describing date seeds as a significant raw material for pyrolysis, designing pyrolysis reactors, and understanding the mechanism of date seed pyrolysis in detail. |
