Abstract

The volume reaction model based on a second-order rate equation with a first-order dependence on each solid and gaseous reactant concentration was solved to predict the detailed performance of gas-solid reactions. The model was discussed in relation to the shrinking core model and the homogeneous reaction model and also compared with the volume reaction model based on the first-order rate expression.
The predicted results are verified in the oxidation of iron sulfide particles to describe the general behavior in the wide region extending from chemical reaction control to diffusion control.
