Its core model was, until now, a proprietary technology (which has provided success since 2009).
Accordingly, a modified form of shrinking core model was used to take these variations into account.
Sharp interface unreacted core model was used for simulation of this process.
An unreacted core model was applied to estimate the activation energy of Cr2O3 reduction with 128 ± 4 kJ/mol.
A shrinking core model was then employed to determine the activation energy and pre-exponential factor under these conditions.
To describe the radial variation of oxygen concentration within the pellet, a dead core model was used.
The unreacted shrinking core model was chosen to describe this non-catalytic solid/gas (hydrated sorbent/SO2) reaction mechanism.
The core model was a 300 × 25 mm single sand-packed tube model with permeability of 3,000 × 10 3 μm2.
