A two dimensional, heterogeneous model was developed for the simulation of a coked catalyst regeneration fixed-bed reactor in a green acrylics process. A kinetic model which consists of combustion of coke containing carbon, hydrogen and oxygen was derived. The unknown parameters (including the kinetic parameters, initial composition and concentration of coke, heat transfer parameters and catalyst pore diameter) were identified using the results of regeneration experiments with the coke formed in a glycerol dehydration process. Good agreements between the model predictions and experimental results were obtained.
