A fixed bed gasification model has been developed by using Aspen Plus as the simulation and modelling tool. The feedstock chosen consisted of raw empty fruit bunch (EFB) and torrefied EFB at 300°C. The hydrogen gas composition obtained using fixed bed gasification model from all feedstock were then analysed together with lower heating value (LHV) and cold gas efficiency (CGE). The simulation results show that as the gasifier temperature is increased, the amount of hydrogen produced is also increased and an increment of air-to-biomass ratio (ABR) reduces the amount of hydrogen produced. Besides, the torrefied EFB produced a higher amount of hydrogen gas (6.52%) at gasifier temperature of 800°C and air-to-biomass ratio (ABR) of 0.2 compared to raw EFB (5.09%). This indicates that torrefied biomass at higher temperature improves hydrogen production. In addition, the use of torrefied biomass also contributes to higher LHV and increases the efficiency of the gasification process.
