Abstract:

ASPEN PlusTM model is developed for the biomass gasification using the Adsorption Enhanced Reforming (AER) process with Dual Fluidized Bed (DFB). The model is validated against the experimental data in DFB mode and semi­batch mode which are conducted by a DFB facility in IFK at 650 °C. The simulation prediction is in good agreement with the experimental data such as gas components, Cold Gas Efficiency (CGE), Lower Heating Value (LHV) and gas. The gasification efficiency, which indicates the efficiency of AER process, is also evaluated. The sensitivity analyses are also conducted and compared with the experimental data conducted in the temperature range between 600 °C and 850 °C. The H2 concentration is well estimated in the whole temperature range except 750 °C. The maximum H2 concentration can be seen in the temperature range at 650 °C. LHV is also well simulated and is decreased up to 10 MJ/m3S.T.P at 750 °C. In the high temperature range, the CGE and gas yield are well predicted as the experimental data. The tendencies of the CGE and gas yield with the gasification temperature increase are the same as the experimental results. The gasification efficiency is increased with temperature increase in both modes.
