Abstract:
The present work concerns with CFD modelling of biomass fast pyrolysis in a fluidised bed reactor.
Initially, a study was conducted to understand the hydrodynamics of the fluidised bed reactor by investigating
the particle density and size, and gas velocity effect. With the basic understanding of hydrodynamics,
the study was further extended to investigate the different kinetic schemes for biomass fast
pyrolysis process. The Eulerian–Eulerian approach was used to model the complex multiphase flows in
the reactor. The yield of the products from the simulation was compared with the experimental data.
A good comparison was obtained between the literature results and CFD simulation. It is also found that
CFD prediction with the advanced kinetic scheme is better when compared to other schemes. With the
confidence obtained from the CFD models, a parametric study was carried out to study the effect of
biomass particle type and size and temperature on the yield of the products.
