Abstract: Gasification is a thermo-chemical process which converts carbonaceous materials into producer gas or chemical feedstock. The present paper deals with a review on experimental investigations and ASPEN Plus simulations of fluidized bed biomass gasification. In experimental investigation the effect of gasifying agent, bed temperature, equivalence ratio (ER), steam to biomass ratio (SBR) and sorbent to biomass ratio (SOBR), bed material are considered. From the review of experimental works, it is observed that the performance of biomass gasification greatly depends on operating parameters such as equivalence ratio, steam to biomass ratio, temperature, gasifying agent, biomass, catalyst and type of sorbent used. On the other hand, review on ASPEN plus simulation deals with the modeling and simulation of biomass gasification through equilibrium model, kinetic model and combination of both. It is found that kinetic models can predict the temporal and spatial variation of gasification products compared to the maximum achievable yield predicted by the equilibrium model. Even though more accurate, kinetic models are more computationally intensive due to the inclusion of reaction kinetics and hydrodynamics compared to equilibrium models.
