2. Case where reaction volume and transfer properties remain constant
We're going to look at the modeling of the solid consumable particle.
This type of model can be applied to the regeneration of a catalyst poisoned by a carbon deposit or a poison contained in the feed or, more generally, to any interaction of a solid phase dispersed in an inert solid support. The model can also be applied to a pure-body particle whose reaction volume remains constant, and where the operating regime throughout the transformation remains in the chemical regime.
2.1 Modeling
The solid particle B is represented by the pseudo-homogeneous sheet model (cf. ) in the absence of convective gas flow, the material and energy balances are written as follows.
