The paper presents a CFD model of a bed reactor for biomass pyrolysis. The input data for the model are kinetic coefficients obtained by an original numerical method based on mathematical processing of thermogravimetric and mass spectrometric curves of biomass pyrolysis. Validation of the model on the basis of experimental results is carried out. The description of the used kinetic model, heat and mass transfer mechanisms is given. The developed model is characterized by coefficients of determination 0.82-0.85 with respect to the experimental data, and shows the best convergence at the temperature program aimed at exposure at 480°C. The developed model can be used for scaling of pyrolysis reactors.
