Advanced simulation of biomass gasification in a fluidized bed reactor using ASPEN PLUS

A mathematical model of biomass gasification in bubbling fluidized gasifier has been developed in ASPEN PLUS. A sub-model for tar generation and cracking is included in this study. The model is capable of dealing with wide variety of biomasses and fluidizing agents, i.e. air, oxygen, steam and carbon di oxide or a mix of these gases. A comparison with experimental data and other simulation results was done. Results show that defining tar and its kinetics significantly improves model performance and its credibility.
