摘要：Biomass from EFB is considered as potential renewable energy sources to be developed in Indonesia. EFB can be efficiently converted into valuable and useful gaseous products through gasification. Research about EFB gasification in various gasifier has been done, though little research about EFB simulation on CFB bed gasifier. The aim of this research is to simulate gasification of EFB on CFB gasifier by assuming that the gasification reaction isunder equilibrium condition. Method encompasses biomass feedstock, simulation basis manager, process description, simulation description, model validation, and sensitivity analysis. The model predicts H2 and CO fraction on syngas product in agreement with published real CFB gasification operation. The result shows that CFB gasifier performance is improving at high temperature above 800°C., and syngas conversion is higher under high temperature.The highest H2 yield achieved at 800°C.Impact of S/B has been investigated, and it is found that when value of S/B is increasing, the more H2 produced. The value of ER below 1 is desired since the focus is to get CO together with H2. The lower ER value the higher syngas yield obtained. The model will be used as a basis for further chemical production simulation from EFB gasification.
