As can be seen, the results agree satisfactorily, enabling cross-validation between the present model and the others mentioned. Note, however, that the model by Teklay et al. ( ) -more complex in the description of the phenomena in the solid phase and the chemical kinetics of the flash calcination of kaolinite -is intended for the simulation of the calcination of kaolinite in a fluidized bed reactor (for which 𝑡 ́ should be interpreted as the "clock" time). This good predictive ability of SAS compared to more complex models is discussed a little in section 7.4.
