A model describing the three-stage noncatalytic gas–solid reactions is presented in this paper. With the equations describing the relationship between the fractional conversion of solid reactant and the reaction time scale, two general features are obtained for this three-stage model. The theoretical prediction of the transport of gaseous reactant through the porous media of a fixed bed column using this three-stage model is also presented in this paper.
