Abstract:
Mathematical modelling of a continuous fluidized-bed reactor has been carried out for non-catalytic gas–solid reactions. The two-phase bubblingbed model has been used. The feed stream size distribution with reversible or irreversible first-order kinetics can be considered by the model. The Grain model was used for non-catalytic reduction of solid reactants. A program was developed in MATLAB software for solving the governing equations at conditions of differenttemperatures and pressures. The model was validated using experimental data and simulation results available in the literature for the iron orereduction with a gas mixture containing hydrogen and was also used for predicting the extent of reaction for reduction of cobalt oxide by methane.
