Abstract
The purpose of this paper is to investigate the validity of a lumped model, i.e. a reaction front model, for the simulation of solid absorption process. A distributed model is developed for solid absorption process, and a dimensionless RF number is suggested to predict the qualitative shape of reaction degree profile. The simulation results from the reaction front model are compared with those from the distributed model solved by a finite difference scheme, and it is shown that they are in good agreement in almost all cases, no matter whether there is reaction front or not.
