The model correctly describes the trend of the evolution of surface area and pore volume, in the sense that they both increase with burn-off and then decrease once a threshold burn-off has been reached. The agreement between the simulated pore volume and the data is good up to 25% burn-off, beyond which the model underpredicts the data. Furthermore, the maximum in the pore volume observed experimentally occurs at about 70% burnoff, while the model predicts a value of 85%.
