Comprehensive CFD modelling of solar fast pyrolysis of beech wood pellets

On this basis, char, tar and gas predicted yields are compared with experimental data. In addition, the gas composition (CH4, CO, CO2, H2 and CxHy) is also compared. CFD results are in good agreement with the experimental values, validating this approach as a useful tool to predict the products yields and their composition when pyrolyzing biomass particles. Furthermore, the model can be used when modelling any process where pyrolysis occurs and it can even be easily coupled to any reactor scale model.
