A comparison of transient reactor models for non-catalytic gas-solid processing

Transient behaviour of packed bed reactors for non-catalytic gas-solid reactions has been simulated using the sharp interface, finite reaction zone and the particle-pellet model for the reaction process occurring within the individual pellets. The solution procedures to the system of equations is based on the orthogonal collocation method. The effect of perturbations in the reactor inlet conditions on the temperature profiles encountered in the bed has also been examined.
