Résumé : |
tests were carried out in a thermobalance using carbon from leather shavings char, under isothermal conditions and atmospheric pressure. The experimental results showed a good fit with the Shrinking Unreacted-Core model controlled by chemical reaction, and the Progressive-Conversion model did not describe the process. According to Shrinking Unreacted-Core model, the reaction initially occurs on the external surface of the particle and the reaction zone moves toward the center of the particle, leaving behind a layer of inert solid (ash). On the other hand, in the Progressive-Conversion model reaction occurs simultaneously in the entire volume of the particle. The activation energies of the C-O2 and C-CO2 reactions were determinate, as well as their reaction orders. |
